News on the X-ray emission from hot subdwarf stars
N. La Palombara, S. Mereghetti
In latest years, the high sensitivity of the instruments on-board the XMM-Newton and Chandra satellites allowed us to explore the properties of the X-ray emission from hot subdwarf…
A young contracting white dwarf in the peculiar binary HD 49798/RX J0648.0--4418?
S. B. Popov, S. Mereghetti, S. I. Blinnikov +2
HD 49798/RX J0648.0--4418 is a peculiar X-ray binary with a hot subdwarf (sdO) mass donor. The nature of the accreting compact object is not known, but its spin period ~s a…
INTEGRAL Detection of the First Prompt Gamma-Ray Signal Coincident with the Gravitational Wave Event GW170817
V. Savchenko, C. Ferrigno, E. Kuulkers +20
We report the e INTernational Gamma-ray Astrophysics Laboratory (INTEGRAL) detection of the short gamma-ray burst GRB 170817A (discovered by Fermi-GBM) with a signal-to-noise ratio…
The radio and X-ray mode-switching pulsar PSR B0943+10
Sandro Mereghetti, Michela Rigoselli
Observations obtained in the last years challenged the widespread notion that rotation-powered neutron stars are steady X-ray emitters. Besides a few allegedly rotation-powered neu…
Behind the dust curtain: the spectacular case of GRB 160623A
F. Pintore, A. Tiengo, S. Mereghetti +6
We report on the X-ray dust-scattering features observed around the afterglow of the gamma ray burst GRB 160623A. With an XMM-Newton observation carried out ~2 days after the burst…
INTEGRAL observations of GW170104
V. Savchenko, C. Ferrigno, E. Bozzo +16
We used data from the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) to set upper-limits on the -ray and hard X-ray prompt emission associated with the gravitational…
