Detection of kilosecond hard lags in the new pulsating ULX candidate NGC 7456 ULX-1
W. Leone, F. Pintore, C. Pinto +19
Context. Ultraluminous X-ray sources (ULXs) are thought to be powered, in many cases, by super-Eddington accretion onto compact objects. While soft X-ray lags have been detected in…
Stellar flare detection in XMM-Newton with gradient boosted trees
Mario Pasquato, Martino Marelli, Andrea De Luca +5
The EXTraS project, based on data collected with the XMM-Newton observatory, provided us with a vast amount of light curves for X-ray sources. For each light curve, EXTraS also pro…
4XMM J181330.1-175110: a new supergiant fast X-ray transient
M. Marelli, L. Sidoli, M. Polletta +3
Supergiant Fast X-ray Transients (SFXT) are a sub-class of High Mass X-ray Binaries (HMXB) in which a compact object accretes part of the clumpy wind of the blue supergiant compani…
Skipping a beat: discovery of persistent quasi-periodic oscillations associated with pulsed fraction drop of the spin signal in M51 ULX-7
Matteo Imbrogno, Sara Elisa Motta, Roberta Amato +24
The discovery of pulsations in (at least) six ultraluminous X-ray sources (ULXs) has shown that neutron stars can accrete at (highly) super-Eddington rates, challenging the standar…
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…
Multiwavelength observations of PSR J2021+4026 across a mode change reveal a phase shift in its X-ray emission
M. Razzano, A. Fiori, P. M. Saz Parkinson +6
Context. We have investigated the multiwavelength emission of PSR J2021+4026, the only isolated gamma-ray pulsar known to be variable, which in October 2011 underwent a simultaneou…
