Introduction
Pierantonio Cinzano made the First World Atlas of Night Sky Brightness, based on satellite measurements. In 2001 he set up the first Laboratory of Photometry and Radiometry of Light Pollution (LPLAB) and, in 2003, the first instrument for photometrical and spectroscopical mapping of the Night Sky Brightness (WASBAM). In 2012 presented Extended Garstang Models, a numerical solution of the radiative transfer problem applied to the propagation of light pollution, and the LPTRAN software package.

Methods to map artificial night sky brightness and stellar visibility across large territories or their distribution over the entire sky at any site are based on the computation of the propagation of light pollution with Garstang models, a simplified solution of the radiative transfer problem in the atmosphere which allows a fast computation by red...
Article
We apply the sky brightness modelling technique introduced and developed by Roy Garstang to high-resolution DMSP-OLS satellite measurements of upward artificial light flux and to GTOPO30 digital elevation data in order to predict the brightness distribution of the night sky at a given site in the primary astronomical photometric bands for a range o...

We present the first World Atlas of the zenith artificial night sky brightness at sea level. Based on radiance calibrated high resolution DMSP satellite data and on accurate modelling of light propagation in the atmosphere, it provides a nearly global picture of how mankind is proceeding to envelope itself in a luminous fog. Comparing the Atlas wit...

Artificial lights raise night sky luminance, creating the most visible effect of light pollution-artificial skyglow. Despite the increasing interest among scientists in fields such as ecology, astronomy, health care, and land-use planning, light pollution lacks a current quantification of its magnitude on a global scale. To overcome this, we presen...

Light pollution is one of the most rapidly increasing types of environmental degradation. To limit this pollution several effective practices have been defined: shields on lighting fixtures to prevent direct upward light; no over lighting, i.e. avoid using higher lighting levels than strictly needed for the task, constraining illumination to the ar...

Background: Artificial light at night affects locations distant from its source through light scattered back to earth from the sky (sky glow). Sky glow is visible in protected and undeveloped areas hundreds of kilometers from large cities. It degrades the scenic quality of the night sky, and may alter nocturnal environments and the visual performan...

We present Roadpollution, a software to compute main parameters of road lighting design and many useful parameters related to the produced light pollution and the energy waste.

Article

We present the results of a comparison of light pollution produced by some light installations for roadway lighting as obtained with the software Roadpollution. Luminaires with an direct upward flux factor apparently as small as 0.2% and 2.2% produce increases of light pollution even of the order of 20% and 200% respectively. Reflection of downward...

We present the kinematics and photometry of the stars and of the ionized gas near the centre of the S0 galaxy NGC4036. Dynamical models based on the Jeans Equation have been constructed from the stellar data to determine the gravitational potential in which the ionized gas is expected to orbit. Inside 10'', the observed gas rotation curve falls wel...

The kinematics of stars and ionized gas has been studied near the center of the S0 galaxy NGC 4036. Dynamical models based both on stellar photometry and kinematics have been built in order to derive the gravitational potential in which the gas is expected to orbit. The observed gas rotation curve falls short of the circular velocity curve inferred...

Light pollution, the alteration of the natural light levels in the night environment produced by man-made light, is one of the most rapidly increasing threats to the natural environment. The fast growth of the night sky brightness due to light pollution not only is damaging the perception of the starry sky but it is silently altering even the perce...

Recent analysis of extended rotation curves of late-type spirals have confirmed that these objects have detectable amounts of dark matter (DM) already in the optical region, with dark-to-luminous mass ratio scaling inversely with luminosity. Since currently available rotation curves of early-type spirals are often fragmentary and not extended enoug...

The knowledge of the contribution $b_d(d)$ to the artificial sky luminance in a given point of the sky of a site produced by the sources beyond a given distance $d$ from it is important to understand the behaviour of light pollution in diffusely urbanized areas and to estimate which fraction of the artificial luminance would be regulated by norms o...

The direction of the upward light emission has different polluting effects on the sky depending on the distance of the observation site. We studied with detailed models for light pollution propagation the ratio $(b_{H})/(b_{L})$, at given distances from a city, between the artificial sky luminance $b_{H}$ produced by its upward light emission betwe...

We present stellar and ionized-gas velocity curves and velocity dispersion profiles for the Sa galaxies NGC 2179 and NGC 2775. Using their luminosity profiles and modeling both their stellar and gaseous kinematics, we have derived the mass distribution of the dark and the luminous matter. This unambiguously shows that, inside one disk length-scale...

We report the discovery of two counterrotating stellar disks in the early-type spiral galaxy NGC 3593. The major axis kinematics shows the presence of two dynamically cold counterrotating components. The surface brightness profile is well reproduced by the sum of the contributions of two exponential disks of different scale lengths (r1 = 40''; r2 =...

Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components of a sample of S0 galaxies. In all galaxies the central velocity dispersion of the ionized gas exceeds 150 km s-1. In some galaxies the gas dispersion remains as high as the stellar one over an extended radial range, showing that random motion...
