Precision engineering for astronomy: historical origins and the future revolution in ground-based astronomy [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
Abstract Since the dawn of civilization, the human race has pushed technology to the limit to study the heavens in ever-increasing detail. As astronomical instruments have evolved from those built by Tycho Brahe in the sixteenth century, through Galileo and Newton in the seventeenth, to the present day, astronomers have made ever more

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.

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 ...

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).
