The high-$x$ data from the ZEUS Collaboration are used to extract parton density distributions of the proton deep in the perturbative regime of QCD. The data primarily constrain the up-quark valence distribution and new results are presented on its $x$-dependence as well as on the momentum carried by the up-quark. The results were obtained using Ba...

Several marginally significant associations between high-energy neutrinos and potential astrophysical sources have been recently reported, but a conclusive identification of these sources remains challenging. We explore the use of Monte Carlo simulations to gain deeper insight into the implications of, in particular, the IC170922A-TXS 0506+056 obse...

Dark matter, cosmic rays, otherworldly lightning, and meteors. Not bad for a day’s work. That’s the ambitious workload researchers have charged to Mini-EUSO, a revolutionary new telescope peering back at earth from aboard the International Space Station.

We present constraints on an astrophysical population of neutrino sources imposed by recent data from the IceCube neutrino observatory. By using the IceCube point source search method to model the detection of sources, our detection criterion is more sensitive than using the observation of high-energy neutrino multiplets for source identification....

In this way, possible associations with astrophysical source populations can be assessed in a physically and statistically principled...
