NuSTAR/XMM-Newton monitoring of the Seyfert 1 galaxy HE 1143-1810. Testing the two-corona scenario
F. Ursini, P. -O. Petrucci, S. Bianchi +11
We test the two-corona accretion scenario for active galactic nuclei in the case of the `bare' Seyfert 1 galaxy HE 1143-1810. We perform a detailed study of the broad-band UV--X-ra…
ESA Voyage 2050 white paper: A Polarized View of the Hot and Violent Universe
Paolo Soffitta, Niccolò Bucciantini, Eugene Churazov +27
Since the birth of X-ray Astronomy, spectacular advances have been seen in the imaging, spectroscopic and timing studies of the hot and violent X-ray Universe, and further leaps fo…
A Black Hole X-ray Binary at 100 Hz: Multiwavelength Timing of MAXI J1820+070 with HiPERCAM and NICER
J. A. Paice, P. Gandhi, T. Shahbaz +12
We report on simultaneous sub-second optical and X-ray timing observations of the low mass X-ray binary black hole candidate MAXI J1820+070. The bright 2018 outburst rise allowed s…
A unified accretion-ejection paradigm for black hole X-ray binaries. IV. Replication of the 2010--2011 activity cycle of GX 339-4
G. Marcel, J. Ferreira, M. Clavel +8
Transients XrB exhibit different spectral shapes during their evolution. In luminosity-color diagrams, their X-ray behavior forms unexplained q-shaped cycles. We proposed a framewo…
