The Cherenkov Telescope Array Observatory (CTAO) is the next-genration very-high energy gamma-ray observatory with two observation stations, one in the Canary island of La Palma (Spain) and the other in the Paranal desert in Chile. Designed to operate for 30 years, the CTAO will function as an open, proposal-driven facility, offering access to researchers worldwide.
The CTAO is nearing a...
The powerful array of instruments and flexible rapid response provided by the European Southern Observatory has led to it playing a major role in the science enabled by Swift in the past 20 years. This has included obtaining numerous redshifts, observations of breakthrough events (including several of the highest redshift GRBs) and their host galaxies, and building up of statistical samples...
Fast X-ray Transients (FXTs) are minute-to-hours long flashes of
X-rays, first discovered serendipitously in X-ray satellite data
(e.g., Chandra, XMM-Newton, and Swift). They are proven to be caused by
energetic extra-galactic phenomena. Currently, Einstein Probe is
revolutionizing the field by discovering many FXTs and, crucially, by
their low-latency announcement thereof. These...
On September 22, 2017, the IceCube Neutrino Observatory detected a high-energy neutrino of potential astrophysical origin which was found by follow-up electromagnetic observations to spatially and temporally coincide with the flaring state of a known blazar, TXS 0506+056. Since then, several additional neutrino events have been found in spatial correlation with known high-energy sources....
VERITAS is one of the world’s most sensitive detectors of astrophysical very high energy (VHE; E> 100 GeV) gamma rays. The array is located in southern Arizona, USA and is made up of four 12-m imaging atmospheric Cherenkov telescopes (IACTs). With nearly 20 years of operation since the first telescope’s installation was complete, the instrument has been able to study Galactic sources such as...
