Ground-based gamma-ray astronomy [PDF]

open access: yesAIP Conference Proceedings, 2000
Ground-based gamma-ray astronomy has become an active astrophysical discipline with four confirmed sources of TeV gamma rays, two plerionic supernova remnants (SNRs) and two BL Lac objects (BL Lacs). An additional nine objects (one plerion, three shell-type SNRs, one X-ray binary, and four BL Lacs) have been detected but have not been confirmed by ...

Future Developments in Ground-Based Gamma-Ray Astronomy

open access: yes, 2023
Ground-based gamma-ray astronomy is a powerful tool to study cosmic-ray physics, providing a diagnostic of the high-energy processes at work in the most extreme astrophysical accelerators of the universe. Ground-based gamma-ray detectors apply a number of experimental techniques to measure the products of air showers induced by the primary gamma-rays ...

Characteristics of extensive air showers around the energy threshold for ground-particle-based $$\gamma $$ γ -ray observatories

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
Very-high-energy $$\gamma $$ γ -ray astronomy based on the measurement of air shower particles at ground-level has only recently been established as a viable approach, complementing the well established air Cherenkov technique.

Search for Sub-Solar Mass Binaries with Einstein Telescope and Cosmic Explorer

open access: yesEntropy, 2022
A possible detection of sub-solar mass ultra-compact objects would lead to new perspectives on the existence of black holes that are not of astrophysical origin and/or pertain to formation scenarios of exotic ultra-compact objects.

Multi-messenger astrophysics of black holes and neutron stars as probed by ground-based gravitational wave detectors: from present to future

open access: yesFrontiers in Astronomy and Space Sciences
The ground-based gravitational wave (GW) detectors LIGO and Virgo have enabled the birth of multi-messenger GW astronomy via the detection of GWs from merging stellar-mass black holes (BHs) and neutron stars (NSs).
