Unprecedentedly bright X-ray flaring in Cygnus X-1 observed by INTEGRAL

P. Thalhammer, T. Bouchet, J. Rodriguez +15

We study three extraordinarily bright X-ray flares originating from Cyg X-1 seen on 2023 July 10 detected with INTEGRAL. The flares had a duration on the order of only ten minutes…

Burst-induced coronal cooling in GS 1826-24 The clock wagging its tail

C. Sánchez-Fernández, J. J. E. Kajava, J. Poutanen +2

Type I X-ray bursts in GS 1826-24, and in several other systems, may induce cooling of the hot inner accretion flow that surrounds the bursting neutron star. Given that GS 1826-24…

Rapid spectral transition of the black hole binary V404 Cyg

J. J. E. Kajava, C. Sánchez-Fernández, J. Alfonso-Garzón +2

During the June 2015 outburst of the black hole binary V404 Cyg, rapid changes in the X-ray brightness and spectra were common. The INTEGRAL monitoring campaign detected spectacula…

Optical/X-ray correlations during the V404 Cyg June 2015 outburst

J. Alfonso-Garzón, C. Sánchez-Fernández, P. A. Charles +6

We present a multiwavelength analysis of the simultaneous optical and X-ray light curves of the microquasar V404 Cyg during the June 2015 outburst. We have performed a comprehensiv…

A faint outburst of the accreting millisecond X-ray pulsar SAX J1748.9-2021 in NGC 6440

F. Pintore, A. Sanna, A. Riggio +6

SAX J1748.9-2021 is an accreting X-ray millisecond pulsar observed in outburst five times since its discovery in 1998. In early October 2017, the source started its sixth outburst,…

The December 2015 re-brightening of V404 Cyg: Variable absorption from the accretion disc outflow

J. J. E. Kajava, S. E. Motta, C. Sánchez-Fernández +1

In December 2015 the black hole binary V404 Cyg underwent a secondary outburst after the main June 2015 event. We monitored this re-brightening with the INTEGRAL and Swift satellit…
