The restless population of bright X-ray sources of NCG 3621
A. Sacchi, M. Imbrogno, S. E. Motta +9
We report on the multi-year evolution of the population of X-ray sources in the nuclear region of NGC 3621 based on Chandra, XMM-Newton and Swift observations. Among these, two sou…
A puzzling 2-hour X-ray periodicity in the 1.5-hour orbital period black widow PSR J1311-3430
Andrea De Luca, Martino Marelli, Sandro Mereghetti +3
Time-domain analysis of an archival XMM-Newton observation unveiled a very unusual variability pattern in the soft X-ray emission of PSR J1311-3430, a black widow millisecond pulsa…
Exploring X-ray variability with unsupervised machine learning I. Self-organizing maps applied to XMM-Newton data
Miloš Kovačević, Mario Pasquato, Martino Marelli +3
XMM-Newton provides unprecedented insight into the X-ray Universe, recording variability information for hundreds of thousands of sources. Manually searching for interesting patter…
Recurrent X-ray flares of the black hole candidate in the globular cluster RZ 2109 in NGC 4472
A. Tiengo, P. Esposito, M. Toscani +7
We report on the systematic analysis of the X-ray observations of the ultra-luminous X-ray source XMMU J122939.7+075333 located in the globular cluster RZ 2109 in the Virgo galaxy…
A Multi-wavelength search for Black Widows and Redbacks counterparts of candidate -ray millisecond pulsars
C. Braglia, R. P. Mignani, A. Belfiore +6
The wealth of detections of millisecond pulsars (MSPs) in -rays by {\em Fermi} has spurred searches for these objects among the several unidentified -ray sources. Interesting…
A Supernova Candidate at z=0.092 in XMM-Newton Archival Data
G. Novara, P. Esposito, A. Tiengo +14
During a search for X-ray transients in the XMM-Newton archive within the EXTraS project, we discovered a new X-ray source that is detected only during a ~5 min interval of a ~21 h…
