The nature of dark matter particle is one of the biggest puzzles in physics today. Gamma-rays (as measured by e.g. Fermi LAT NASA satellite) are particularly powerful ways to test one of the most popular particle physics proposal, WIMPs. However, to test particle physics properties via gamma-rays, d ...

The recently identified source class of pulsar haloes may be numerous and bright enough in the TeV energy range to constitute a large fraction of the sources that will be observed with the Cherenkov Telescope Array (CTA). In this work, we quantify the prospects for detecting and characterizing pulsa ...

The upcoming Cherenkov Telescope Array (CTA) will dramatically improve the point-source sensitivity compared to the current Imaging Atmospheric Cherenkov Telescopes (IACTs). One of the key science projects of CTA will be a survey of the whole Galactic plane (GPS) using both southern and northern obs ...

The Cherenkov Telescope Array Observatory (CTAO) will be a ground-based Cherenkov telescope performing wide-sky surveys, ideal for anisotropy studies such as cross-correlations with tracers of the cosmic large-scale structure. Cross-correlations can shed light on high-energy γ-ray sources and potent ...

Numerous observations confirm the existence of dark matter (DM) at astrophysical and cosmological
scales, yet the fundamental nature of this elusive component of our Universe remains unknown. Theory and
simulations of Galaxy formation predict that DM should cluster on small scales in bound structu ...

Aims: Traditional star-galaxy classification techniques often rely on feature estimation from catalogs, a process susceptible to introducing inaccuracies, thereby potentially jeopardizing the classification’s reliability. Certain galaxies, especially those not manifesting as extended sources, can be ...

The TeV extragalactic sky is dominated by blazars, radio-loud active galactic nuclei with a
relativistic jet pointing towards the Earth. Blazars show variability that can be quite exceptional
both in terms of flux (orders of magnitude of brightening) and time (down to the minute timescale).

The Cherenkov Telescope Array (CTA) will be the next-generation observatory in the field of very-high-energy (20 GeV to 300 TeV) gamma-ray astroparticle physics. The traditional approach to data analysis in this field is to apply quality cuts, optimized using Monte Carlo simulations, on the data acq ...
