Discovery of X-ray Polarization from the Black Hole Transient Swift J1727.8-1613

Alexandra Veledina, Fabio Muleri, Michal Dovciak +113

We report the first detection of the X-ray polarization of the bright transient Swift J1727.8-1613 with the Imaging X-ray Polarimetry Explorer. The observation was performed at the…

First X-ray polarization measurement confirms the low black-hole spin in LMC X-3

Jiří Svoboda, Michal Dovčiak, James F. Steiner +109

X-ray polarization is a powerful tool to investigate the geometry of accreting material around black holes, allowing independent measurements of the black hole spin and orientation…

Fundamental scaling relationships revealed in the optical light curves of tidal disruption events

Andrew Mummery, Sjoert van Velzen, Edward Nathan +4

We present fundamental scaling relationships between properties of the optical/UV light curves of tidal disruption events (TDEs) and the mass of the black hole that disrupted the s…

The Luminous, Hard State Can't Be MAD

P. Chris Fragile, Koushik Chatterjee, Adam Ingram +1

We present a straightforward argument for why the luminous, hard state of black hole X-ray binaries (BHXRBs) cannot always be associated with a magnetically arrested accretion disc…

Discovery of strongly variable X-ray polarization in the neutron star low-mass X-ray binary transient XTE J1701462

Massimo Cocchi, Andrea Gnarini, Sergio Fabiani +105

After about 16 years since its first outburst, the transient neutron star low-mass X-ray binary XTE J1701462 turned on again in September 2022, allowing for the first study of i…

The First X-ray Polarization Observation of the Black Hole X-ray Binary 4U 1630-47 in the Steep Power Law State

Nicole Rodriguez Cavero, Lorenzo Marra, Henric Krawczynski +107

The Imaging X-ray Polarimetry Explorer (IXPE) observed the black hole X-ray binary 4U 1630-47 in the steep power law (or very high) state. The observations reveal a linear polariza…
