Detection of an Extremely Luminous Radio Counterpart to the Be/X-ray Binary A0538-66
Justine Crook-Mansour, Rob Fender, Alex Andersson +14
We present the discovery of radio emission from the Be/X-ray binary A0538-66 with the Australian Square Kilometre Array Pathfinder (ASKAP), and results from a subsequent weekly mon…
The very faint X-ray transient Swift J174610-290018 at the Galactic center
Giovanni Stel, Gabriele Ponti, Nathalie Degenaar +17
Very Faint X-ray Transients (VFXTs) are a class of X-ray binary systems that exhibit occasional outbursts with peak X-ray luminosities (L_X< 1e36 erg s^-1) much lower than typical…
INTEGRAL IBIS catalog of magnetar bursts
Dominik P. Pacholski, Sandro Mereghetti, Martin Topinka
One of the distinctive properties of magnetars, young neutron stars powered mainly by magnetic energy, is the emission of short (1 s) bursts of hard X-rays. Such bursts h…
A magnetar outburst with atypical evolution: the case of Swift J1555.2-5402
A. Borghese, F. Coti Zelati, M. Imbrogno +12
The magnetar Swift J1555.2-5402 was discovered in outburst on 2021 June 3 by the Burst Alert Telescope on board the Swift satellite. Early X-ray follow-up revealed a spin period P~…
Discovery of a 9.67-s pulsar in an ultraluminous X-ray source in NGC 4631 with XMM-Newton
L. Ducci, S. Mereghetti, F. Pintore +4
Thanks to a recent observation with XMM-Newton, we discovered periodic pulsations at P= 9.6652 +/- 0.0002 s in a new ultraluminous X-ray source (ULX) in the galaxy NGC 4631. This s…
Prospects for Time-Domain and Multi-Messenger Science with eXTP
Shu-Xu Yi, Wen Zhao, Ren-Xin Xu +75
In this new era of time-domain and multi-messenger astronomy, various new transients and new phenomena are constantly being discovered thanks to the rapid advances in observations,…
