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…
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…
The two tails of PSR J2055+2539 as seen by Chandra: analysis of the nebular morphology and pulsar proper motion
Martino Marelli, Andrea Tiengo, Andrea De Luca +4
We analyzed two Chandra observations of PSR J2055+2539 (for a total integration time of 130 ks) in order to measure its proper motion and study its two elongated nebular feat…
Discovery of a 0.42-s pulsar in the ultraluminous X-ray source NGC 7793 P13
G. L. Israel, A. Papitto, P. Esposito +11
NGC 7793 P13 is a variable (luminosity range ~100) ultraluminous X-ray source (ULX) proposed to host a stellar-mass black hole of less than 15 M in a binary system with o…
