The binary neutron star merger GW170817 was a gravitational-wave event rich with electromagnetic counterparts: a short gamma-ray burst, a kilonova, afterglow radiation from the relativistic outflow and—if further data confirms—afterglow radiation from the slowly expanding nebula. However, this richness is due to the proximity and favorable inclination of this historic event. During upcoming...
In the next decade, the Vera Rubin Observatory Legacy Survey of Space and Time (LSST) will provide an unprecedented volume of optical data of the southern sky. Its public alert stream will communicate the detection of millions of potential transient objects every night. The key to use this stream for GW and high-energy science is to be able to select the small number of extreme astrophysical...
We present the 3UTransat space mission under study at IRAP for the surveillance of the hard X-ray sky with a constellation of cubesats.
The talk will quickly go through the science goals of the mission, the design of the satellites and constellation, the preliminary results of on-going phase-0 study at CNES and science simulations at IRAP, and the planned agenda for the development of the...
