The Role of XMM–Newton in the Investigation of Persistent BeXRBs

Mereghetti, Sandro; Esposito, Paolo; Israel, Gian Luca +2 more

The persistent BeXRBs are a class of high-mass X-ray binaries (HMXRBs), which are characterized by persistent low X-ray luminosities ($$ {L}_{\mathrm{X}}\sim {10}^{34} $$ erg s$$ {}^{-1} $$) and wide ($$ {P}_{\mathrm{orb}}> $$ 30 days), almost circular orbits. In these sources the NS is slowly rotating (with $$ {P}_{\mathrm{spin}} $$ well above…

INTEGRAL Observations of Magnetars

Mereghetti, Sandro; Ducci, Lorenzo; Pacholski, Dominik Patryk +1 more

The INTEGRAL satellite has collected a large amount of data on magnetars in our Galaxy, spanning more than 20 years starting from 2003. The large data set obtained with the IBIS/ISGRI instrument at energies above 20 keV allows us to study both the properties and long-term evolution of their persistent hard X-ray emission and the population charact…
