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

European 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

Entropy, 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

Frontiers 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).
