Jitter radiation as an alternative mechanism for the nonthermal X-ray emission of Cassiopeia A
Emanuele Greco, Jacco Vink, Amael Ellien +1
Synchrotron radiation from relativistic electrons is usually invoked as the responsible for the nonthermal emission observed in Supernova Remnants (SNRs). Diffusive shock accelerat…
Clumpy wind studies and the non-detection of cyclotron line in OAO 1657-415
Pragati Pradhan, Carlo Ferrigno, Biswajit Paul +11
Winds of massive stars are suspected to be inhomogeneous (or clumpy), which biases the measures of their mass loss rates. In High Mass X-ray Binaries (HMXBs), the compact object ca…
Accretion geometry of the neutron star low mass X-ray binary Cyg X-2 from X-ray polarization measurements
R. Farinelli, S. Fabiani, J. Poutanen +92
We report spectro-polarimetric results of an observational campaign of the bright neutron star low-mass X-ray binary Cyg X-2 simultaneously observed by IXPE, NICER and INTEGRAL. Co…
Polarization properties of the weakly magnetized neutron star X-ray binary GS 1826-238 in the high soft state
Fiamma Capitanio, Sergio Fabiani, Andrea Gnarini +94
The launch of the Imaging X-ray Polarimetry Explorer (IXPE) on 2021 December 9 has opened a new window in X-ray astronomy. We report here the results of the first IXPE observation…
Timing analysis of the 2022 outburst of the accreting millisecond X-ray pulsar SAX J1808.43658: hints of an orbital shrinking
Giulia Illiano, Alessandro Papitto, Andrea Sanna +19
We present a pulse timing analysis of NICER observations of the accreting millisecond X-ray pulsar SAX J1808.43658 during the outburst that started on 2022 August 19. Similar to…
XMM-Newton and Swift observations of supergiant high mass X-ray binaries
Carlo Ferrigno, Enrico Bozzo, Patrizia Romano
Wind-fed supergiant X-ray binaries are precious laboratories not only to study accretion under extreme gravity and magnetic field conditions, but also to probe still highly debated…
