In this article, we study the variability of Si iv and C iv broad absorption lines (BALs) between two different epochs in the case of 10 broad absorption-line quasi-stellar objects (BALQSOs). By performing multicomponent analysis of Si iv and C iv broad absorption troughs, we analyse each BAL trough to find the individual and uniquely determined nu...

ASTA is a new spectral analysis software aiming to serve the growing need of an integrated computing environment which will implement efficiently the demanding process of multicomponent analysis. It is a cutting-edge spectral multicomponent analysis software for displaying, fitting and analyzing astronomical spectra of complex emission and absorpti...

In this paper we analyze the C IV and Si IV broad absorption troughs of two BALQSOs (J101056.69+355833.3, J114548.38+393746.6) to the individual components they consist of. By analyzing a BAL trough to its components we have the advantage to study the variations of the individual absorbing systems in the line of sight and not just the variations of...

Yπάρχουν δύο είδη/κατηγορίες αστρολογίας. 1. Η πρώτη κατηγορία περιλαμβάνει τα κείμενα της Εσωτερικής Αστρολογίας, τα οποία περιγράφουν θεωρητικά τη δομή του αισθητού και του μη αισθητού Σύμπαντος. Τα κείμενα αυτά αποτελούν τη βάση πάνω στην οποία τεκμηριώνεται η αστρική και γενικότερα η υπερκόσμια δράση της γήινης και ανθρώπινης, καθώς και της συμ...

Η Αστρολογία δεν πρέπει να συγχέεται με την Αστρονομία, την επιστήμη των νόμων των άστρων, ούτε με την Αστροφυσική την επιστήμη που μελετά τις φυσικές ιδιότητες των άστρων και των ουρανίων σωμάτων γενικότερα. Αν θέλαμε να δώσουμε ένα κάποιον ορισμό για την Αστρολογία, θα λέγαμε ότι Αστρολογία ονομάζεται το σύνολο των παραδόσεων και συστημάτων, τα ο...

Οι σύγχρονες επιστημονικές απόψεις, λογικά, θα έπρεπε να ικανοποιούν τη θεολογική φιλοσοφία και να γεφυρώνουν τις βασικές διαφωνίες της με την Επιστήμη. Σε πολλές περιπτώσεις, η σύνδεση αυτή έχει πραγματοποιηθεί και ένας νέος διάλογος μεταξύ Επιστήμης και Θεολογίας έχει ανοίξει, με στόχο τη διαμόρφωση των νέων πολιτισμικών δεδομένων του «αύριο». Όμ...

Χριστιανική θεολογική σκέψη «εναντίον» Νευτώνειας επιστήμης Σήμερα πλέον, κατά τη γνώμη μας, δύο είναι οι βασικές φιλοσοφικές ή θεολογικές διαφωνίες μεταξύ της χριστιανικής θεολογικής σκέψης και της κλασικής Νευτώνειας επιστήμης. Η πρώτη διχογνωμία αφορά την ύπαρξη μιας αόρατης δημιουργίας η οποία συνυπάρχει, περισσότερο ή λιγότερο με την αισθητή...

Όπως είναι φανερό από όλα τα προηγούμενα, η αλληλεπίδραση μεταξύ Επιστήμης και Θεολογίας έχει βαθιές ρίζες και σε πολλές περιπτώσεις παίρνει εκρηκτικό χαρακτήρα. Το δραματικό γεγονός όμως είναι ότι η παρέμβαση των καμπαλιστικών δυτικών θεολογικών δομών στη συγκρότηση της επιστημονικής σκέψης συνεχίζεται μέχρι σήμερα. Ως παράδειγμα αναφέρουμε την άπ...

Η εμμονή της Δυτικής χριστιανικής Εκκλησίας να στηρίζει τα καμπαλιστικά ιουδαϊκά δόγματα που αφορούσαν την επιστήμη, διατηρήθηκε μέχρι των ημερών μας, όταν υπό την ισχυρή κοινωνική πίεση, άρθηκαν τα αναθέματα που είχαν διατυπωθεί εναντίον σπουδαίων αστρονόμων. Όμως, σε πολλές άλλες περιπτώσεις, τα υλιστικά και μηχανιστικά επιστημονικά χαρακτηριστικ...

Broad Absorption Line QSOs (BALQSOs) are a subtype of radio-quite QSOs that exhibit complex and unusually broad (FWHM ≥ 2,000 km/s) absorption lines. The existence of these lines in BALQSO spectra raises some questions with respect to the properties, the physical conditions and kinematics of the BAL material as well as the morphology of BAL troughs...

In this paper, using the Gauss - Rotation model (GR model), we analyse the UV C IV resonance lines in the spectra of 20 Oe stars of different spectral subtypes, in order to detect the structure of C IV region. We study the presence and behaviour of absorption clouds and analyse their characteristics. From this analysis we can calculate the values o...

We investigate the physical conditions and kinematics of broad absorption line region clouds of Si IV in 21 HiBAL Quasars. We use the Danezis et al. method [1], [2], [3] in order to fit and analyze the broad absorption troughs of Si IV resonance lines in the UV region of the electromagnetic spectrum. We find that the BAL flow is not smooth but inst...

Broad Absorption Line Regions - BALR are composed of a number of successive independent absorbing density layers. Using the GR model, we analyze the UV Si IV ({\lambda}{\lambda}1393.755 - 1402.770), O IV ({\lambda}1401.156) and C IV ({\lambda}{\lambda}1548.187 - 1550.772) resonance lines in the spectra of a certain QSO and discuss the results conce...

Ένα από τα πιο πολυσυζητημένα θέματα της περιόδου που διανύουμε είναι οι σχέσεις μεταξύ Επιστήμης και Τεχνολογίας και η επίδρασή τους στη δομή ενός πολιτισμικού ρεύματος. Ιδιαίτερο ενδιαφέρον έχουν οι απόψεις που συνδέουν το περιεχόμενο της Επιστήμης και της Τεχνολογίας με την ανθρώπινη καθημερινότητα και τη σχέση τους με την παραγωγική διαδικασία...

Θεωρούμε ότι το νέο ανθρωπιστικό πολιτισμικό ρεύμα που ήδη γεννιέται θα στηριχτεί σε τέσσερις βασικές και αποδεικνυόμενες πειραματικά επιστημονικές αλήθειες. Η πρώτη αλήθεια αφορά αυτό που ονομάζουμε υλική πραγματικότητα. Για τη σύγχρονη επιστημονική σκέψη η αισθητή υλική πραγματικότητα, σε οποιοδήποτε επίπεδο, αποτελεί έναmatrix, δηλαδή μια ψεύτικ...

Όπως όλοι έχουμε αντιληφθεί, οι Δυτικές κοινωνίες διέρχονται μια περίοδο δραματικά αυξανόμενης κοινωνικής και πολιτικής κρίσης, η οποία συν τω χρόνω οδηγεί τον Δυτικό πολιτισμό σε κατάρρευση. Είναι σε όλους πια φανερό ότι η διεθνής οικονομική κατάρρευση που βιώνουμε σήμερα δεν είναι το αίτιο, αλλά το αποτέλεσμα μιας ολοκληρωτικής κατάρρευσης αξιών...

Here we consider the presence of absorption components shifted to the violet or red side of the main spectral line (satellite or discrete absorption components, i.e., SACs or DACs) in the regions of the Mg II resonance lines in Be stars as well as their kinematical characteristics. Namely, our objective is to check whether there exists a common phy...

In this review we present our recent investigation of the complex absorption lines in spectra of hot emission stars. The lines are created in a material ejected from stars (here we call it density regions around the objects). Particularly we present a model (GR model) which is developed to study satellite or discrete absorption components (SACs or...

Boad Absorption Line Regions - BALR are composed of a number of successive independent absorbing density layers. Using the GR model, we analyze the UV Si IV (1393.755 - 1402.770), O IV (1401.156) and C IV (1548.187 - 1550.772) resonance lines in the spectra of a certain QSO and discuss the results concerning its kinematic properties (rotational, ra...

Some Hot Emission Stars and AGNs present peculiar spectral line profiles which are due to DACs and SACs phenomena. The origin and the mechanisms which are responsible for the creation of DACs/SACs is an important problem that has been studied by many researchers. This paper is a review of our efforts to study the origin and the mechanisms of these...

Using the GR model, we analyze the UV Si IV resonance lines in the spectra of 68 Be stars of different spectral subtypes, in order to detect the structure of Si IV region. We calculated the values of the rotational, radial and random velocities as well as the absorbed energy of each one of the λλ 1393.755, 1402.778 Å Si IV resonance lines and we pr...

Το Βυζάντιο αποτελεί τον συνδετικό κρίκο ανάμεσα στην ελληνική αρχαιότητα και τη σύγχρονη εποχή, ενώ στο Βυζάντιο βρίσκονται οι ρίζες του νεότερου Ελληνισμού και της Ορθοδοξίας. Έως σήμερα, εν πολλοίς, προσεγγίζαμε τον πολιτισμό του Βυζαντίου κυρίως μέσα από τη θεολογία, παρότι πολλοί λόγιοι στη Βυζαντινή αυτοκρατορία διακρίθηκαν και στις θετικές ε...

Using the GR model, we analyze the ultraviolet Si IV resonance lines in the spectra of 19 Be stars of different spectral subtypes, in order to detect the presence of absorption components and to analyze their characteristics. From this analysis we can calculate the values of a group of physical parameters, such as the apparent rotational and radial...

Using the GR model, we analyze the UV Mg II resonance lines in the spectra of 20 Be stars of different spectral subtypes, in order to detect the presence of satellite or discrete absorption components. The values of some physical parameters -- rotational, radial and random velocities, as well as the FWHM and the absorbed energy, as a function of th...

Most of the Broad Absorption Lines (BALs) in quasars show very complex profiles. An idea to explain these profiles is that the dynamical systems of broad line regions are not homogeneous but consist of a number of dense regions or ion populations with different physical parameters. This approach is used to study the ultraviolet CIV resonance lines...

Classical Newtonian Physics and Euclidean Geometry are currently used to describe biological phenomena and the processes of drug formulation, which are characterized by homogeneity and linearity. On the other hand, at the mesoscopic level, the principles and the laws of physics are quite different from the Classical Newtonian Physics and Euclidean...

Παράλληλα με τον Γαλιλαίο (1564-1642), άνθησε τον 17ο αιώνα η φιλοσοφική σκέψη του Kαρτέσιου (Renatus Cartesius ή René Descartes, 1596-1650), ο οποίος διατύπωσε μια νέα φιλοσοφία για τη φύση. O Γάλλος φιλόσοφος θεωρείται ο πατέρας της σύγχρονης ευρωπαϊκής φιλοσοφίας, εφόσον έως την εποχή του η νεότερη φιλοσοφία ήταν σκόπιμα προσανατολισμένη προς τη...

The notion of the infinite, with the modern meaning of the term, was first introduced by the Greek philosopher Anaximander (6 th Century BC). Anaximander introduced the apeiron (the boundless) as the beginning of everything (the first principle). According to his theory, the apeiron is undefined and ever moving. It gives birth to the contradictory...

Most of Broad Absorption Lines (BALs) in quasars (QSOs) present very complex profiles. This means that we cannot fit them with a known physical distribution. An idea to explain these profiles is that the dynamical systems of Broad Line Regions (BLRs) are not homogeneous but consist of a number of density regions or ion populations with different ph...

A characteristic of the Western thought is the effort to counter Christian theology through arguments based on scientific discoveries (antirrhetic theology). Two objections can be raised against this trait: a) Modern science considers as a fact the future expansions, corrections, even total abolishment of scientific knowledge in the face of new dis...

According to the GR model, the Broad Absorption Line Region (BALR), lie in a disk around the quasar and is composed of a number of successive independent absorbing density regions that have different apparent rotational and radial velocities. By fitting the observed absorption lines with GR model, we can calculate some basic kinematical pa- rameter...

This work explores the relation and interdependence among theology, science and social structure within the framework of a new ``Cultural Current'', which will probably prevail in the Western societies, through the study of the development of the cultural currents in the ages. The now prevailing in these societies Positivist Cultural Current suffer...

In the history of calendrical reforms the Julian calendar that prevailed for centuries was gradually replaced by the Gregorian one from 1582 onwards. After these two calendars, some other calendrical systems were introduced in Europe, none of which prevailed beyond its limited (in time and place) political environment. In this work the following su...

Cosmological views of presocratic philosophers, atomists and thinkers Leucippus and Democritus presented in the lyric poem of Alkman.

Κορυφαία φυσικομαθηματική διάνοια της επιστημονικής επανάστασης του 17ου αιώνα, ο Άγγλος φυσικός, μαθηματικός και αστρονόμος Ισαάκ Νεύτων (Isaac Newton, 1642-1727), γεννήθηκε στις 25 Δεκεμβρίου του 1642 (4 Iανουαρίου του 1643) στο Γούλσθορπ κοντά στο Γκράνθαμ του Λινκολνσάιρ στην Αγγλία.

Hot emission stars (Oe and Be stars) present complex spectral line profiles, which are formed by a number of DACs and/or SACs. In order to explain and reproduce theoretically these complex line profiles we use the GR model (Gauss-Rotation model). This model presupposes that the regions, where the spectral lines are created, consist of a number of i...

We use the GR model in order to fit broad spectral lines (absorption and emission) of several BAL QSOs. According to this motdel, we assume that the Broad Line Regions (BLR), which originate in a disk wind, are composed of a number of successive independent absorbing density layers, which may have different random, rotational and radial velocities....

The relation between philosophy and science has passed from many phases in history and still is an interesting topic. The value of falsifiability (or refutability) in science was stressed by Popper. Here, as a paradigm, the juxtaposition of the Earth-centered view of the universe and the prevalence of the heliocentric theory is examined. A new phys...

Cosmological views of Democritus have been analyzed.

To έτος που διανύουμε, το 2009, καθορίστηκε από τον Ο.Η.Ε., την Ουνέσκο και τη Διεθνή Αστρονομική Ένωση ως διεθνές έτος Αστρονομίας. Ο εορτασμός αυτός αποτελεί για την Ελλάδα ένα σπουδαίο γεγονός, αφού η επιστήμη της Αστρονομίας σ' αυτήν ακριβώς τη χώρα δημιουργήθηκε και εδώ έφτασε σε μεγαλειώδη αποτελέσματα. Δυστυχώς μετά τους σπουδαίους αρχαίους...

Assuming that the Broad Absorption Line Region – BALR (originated in a disk wind) is composed of a number of successive independent absorbing density layers, which have apparent rotational and radial velocities and where ions have random velocities, we applied a model in order to obtain the kinematical parameters of BALR, by fitting the broad absor...
