GECAM (Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor) is an ALL-TIME ALL-SKY monitor for GW EM. It consists of two small satellites in the same Low Earth Orbit (~600 km, 29°) with opposite orbital phase, monitoring instantaneous 100% all-sky from 6 keV to 5 MeV, without a turned-off during the SAA passage.
GECAM shall detect several GW GRBs per year jointly with...
Joint detections between gravitational waves and gamma-ray bursts (GRBs) enable multi-messenger science and allows for constraints on the neutron star equation of state, tests of fundamental physics, and insight into the origin of the prompt emission. To increase the likelihood of these coincident detections, full sky coverage in the gamma-ray regime is needed. BurstCube aims to expand sky...
The Transient High-Energy Sky and Early Universe Surveyor (THESEUS) is a space mission concept currently under Phase A study by ESA as candidate M5 mission, aiming at exploiting Gamma-Ray Bursts for investigating the early Universe and at providing a substantial advancement of multi-messenger and time-domain astrophysics. Through an unprecedented combination of X-/gamma-rays monitors, an...
The discovery of the joint GRB/GW 170817 events opened a new window into the multi-messenger astronomy. The Advanced gravitational wave detectors of second and third generation will observe larger and larger volume of the Universe. While the current optical surveys will suffer of the faint kilonova emission and many contaminants within the gravitational-wave poor sky-localization, and the ...
The polarimetry of gamma rays converting to an e+e- pair would open a new window on the high-energy sky with, among other things, providing insight into the radiation mechanism in young pulsars (curvature or synchrotron) or deciphering the composition of the gamma-ray emitting jets in blazars (leptonic or lepto-hadronic).
The performance of polarimeters based on homogeneous active targets...
