Candidate isolated neutron stars in the 4XMM-DR10 catalog of X-ray sources
Michela Rigoselli, Sandro Mereghetti, Caterina Tresoldi
Most isolated neutron stars have been discovered thanks to the detection of their pulsed non-thermal emission, at wavelengths spanning from radio to gamma-rays. However, if the bea…
INTEGRAL limits on past high-energy activity from FRB 20200120E in M81
Sandro Mereghetti, Martin Topinka, Michela Rigoselli +1
The repeating fast radio burst FRB 20200120E is located in a globular cluster belonging to the nearby M81 galaxy. Its small distance (3.6 Mpc) and accurate localization make it an…
The X-ray evolution and geometry of the 2018 outburst of XTE J1810-197
A. Borghese, N. Rea, R. Turolla +17
After 15 years, in late 2018, the magnetar XTE J1810-197 underwent a second recorded X-ray outburst event and reactivated as a radio pulsar. We initiated an X-ray monitoring campai…
New X-ray observations of the hot subdwarf binary HD49798 / RXJ0648.0-4418
S. Mereghetti, F. Pintore, T. Rauch +7
HD49798 / RXJ0648.0-4418 is the only confirmed X-ray binary in which the mass donor is a hot subdwarf star of O spectral type and, most likely, it contains a massive white dwarf (1…
Scientific simulations and optimization of the XGIS instrument on board THESEUS
Sandro Mereghetti, Giancarlo Ghirlanda, Ruben Salvaterra +12
The XGIS (X and Gamma Imaging Spectrometer) is one of the three instruments onboard the THESEUS mission (ESA M5, currently in Phase-A). Thanks to its wide field of view and good im…
