A deep observation of the X-Persei-like binary system CXOU J225355.1+624336
N. La Palombara, L. Sidoli, P. Esposito +2
We report on the follow-up observation of the persistent X-ray pulsar CXOU J225355.1+624336, discovered with the CATS@BAR project on archival data. The sourc…
IKT16: Discovery of a 22 ms energetic rotation-powered pulsar in the Small Magellanic Cloud
C. Maitra, P. Esposito, A. Tiengo +5
We report here on the discovery with XMM-Newton of pulsations at 22 ms from the central compact source associated with IKT16, a supernova remnant in the Small Magellanic Cloud (SMC…
The EXTraS Project: Exploring the X-ray transient and variable sky
A. De Luca, R. Salvaterra, A. Belfiore +29
Temporal variability in flux and spectral shape is ubiquitous in the X-ray sky and carries crucial information about the nature and emission physics of the sources. The EPIC instru…
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…
The rare X-ray flaring activity of the Ultraluminous X-ray source NGC 4559 X7
Fabio Pintore, S. Motta, C. Pinto +9
Ultraluminous X-ray sources are considered amongst the most extremely accreting objects in the local Universe. The recent discoveries of pulsating neutron stars in ULXs strengthene…
Multi-band observations of Swift J0840.7-3516: a new transient ultra-compact X-ray binary candidate
F. Coti Zelati, A. de Ugarte Postigo, T. D. Russell +5
We report on multi-band observations of the transient source Swift J0840.7-3516, which was detected in outburst in 2020 February by the Neil Gehrels Swift Observatory. The outburst…
