Detection of extended X-ray emission around the PeVatron microquasar V4641 Sgr with XRISM
Hiromasa Suzuki, Naomi Tsuji, Yoshiaki Kanemaru +26
A recent report on the detection of very-high-energy gamma rays from V4641 Sagittarii (V4641 Sgr) up to ~0.8 peta-electronvolt has made it the second confirmed "PeVatron" microquas…
Evolution of the Accretion Disk and Corona During the Outburst of the Neutron Star Transient MAXI J1807+132
Sandeep K. Rout, Teo Munoz-Darias, Jeroen Homan +4
Low-mass X-ray binaries with a neutron star as the primary object show a complex array of phenomenology during outbursts. The observed variability in X-ray emission primarily arise…
Dynamical confirmation of a black hole in the X-ray transient Swift J1727.8-1613
D. Mata Sanchez, M. A. P. Torres, J. Casares +3
The X-ray transient Swift J1727.8-1613 ended its 10-month discovery outburst on June of 2024, when it reached an optical brightness comparable to pre-discovery magnitudes. With the…
Analysis of optical spectroscopy and photometry of the type I X-ray bursting system UW CrB
M. R. Kennedy, P. Callanan, P. M. Garnavich +19
UW Coronae Borealis (UW CrB) is a low mass X-ray binary that shows both Type 1 X-ray and optical bursts, which typically last for 20 s. The system has a binary period of close to 2…
Recovery of the X-ray polarisation of Swift J1727.81613 after the soft-to-hard spectral transition
J. Podgorný, J. Svoboda, M. Dovčiak +34
We report on the detection of X-ray polarisation in the black-hole X-ray binary Swift J1727.81613 during its dim hard spectral state by the Imaging X-ray Polarimetry Explorer (I…
Dramatic Drop in the X-Ray Polarization of Swift J1727.81613 in the Soft Spectral State
Jiří Svoboda, Michal Dovčiak, James F. Steiner +34
Black-hole X-ray binaries exhibit different spectral and timing properties in different accretion states. The X-ray outburst of a recently discovered and extraordinarily bright sou…
Evidence for inflows and outflows in the nearby black hole transient Swift J1727.8-162
D. Mata Sánchez, T. Muñoz-Darias, M. Armas Padilla +2
We present 20 epochs of optical spectroscopy obtained with the GTC-10.4m telescope across the bright discovery outburst of the black hole candidate Swift J1727.8-162. The spectra c…
