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~…
GRB241107A: a Giant Flare from a close-by extragalactic Magnetar?
James Craig Rodi, Dominik Patryk Pacholski, Sandro Mereghetti +5
We report the results on the short gamma-ray burst GRB 241107A, obtained with the IBIS instrument on board the INTEGRAL satellite. The burst had a duration of about 0.2 s, a fluenc…
INTEGRAL search for magnetar giant flares from the Virgo Cluster and in nearby galaxies with high star formation rate
Dominik P. Pacholski, Edoardo Arrigoni, Sandro Mereghetti +1
Giant flares from magnetars can reach, for a fraction of a second, luminosities greater than 10 erg s in the hard X-ray/soft -ray range. This makes them visible a…
INTEGRAL observations of magnetars
Dominik P. Pacholski, Lorenzo Ducci, Martin Topinka +1
The INTEGRAL satellite has collected a large amount of data on magnetars in our Galaxy, spanning more than 20 years starting from 2003. The large data set obtained with the IBIS/IS…
