The talk aims to introduce the status of the field, discuss key recent results and instruments, as well as future perspectives.
Very-high-energy (VHE) gamma-ray astroparticle physics is a relatively young field, and observations over the past decade have surprisingly revealed almost two hundred VHE emitters which appear to act as cosmic particle accelerators. These sources are an important component of the Universe, influencing the evolution of stars and galaxies. At the same time, they also act as a probe of physics...
SiPMs are now widely applied for light detection in particle physics and astroparticle. I will focus on Cherenkov light detection from ground and discuss also some space application. Focus will be construction of cameras and challenges for their operation.
The Very Energetic Radiation Imaging Telescope Array System (VERITAS) consists of four atmospheric Cherenkov telescopes fully operating in the northern hemisphere since 2007. It is located at Fred Lawrence Whipple Observatory in southern Arizona, USA and is sensitive to gamma rays from 85 GeV to 30 TeV energy range. One of the major focuses of the broad science topics of the multinational...
In this presentation, I will discuss how the wide field-of-view, high-duty cycle, and excellent sensitivity at energies above 10 TeV make the HAWC Gamma-Ray Observatory a uniquely suited instrument to survey the Northern Hemisphere sky for cosmic-ray acceleration, distribution, and propagation, gamma-ray transients, dark matter signals, and other fundamental physics phenomena. I will present...
The Fermi Large Area Telescope has been surveying the gamma-ray sky for more than 13 years. With more than 5,000 detected gamma-ray sources, LAT observations have been instrumental to improve our understanding of particle acceleration and gamma-ray production in astrophysical sources. In this talk, I will review recent science highlights from the LAT. In particular, I will focus on transient...
