X-ray luminous late-type giants: an overlooked population contributing to the Galactic ridge iron line emission
Tong Bao, Gabriele Ponti, Xiao-jie Xu +8
The origin of the highly ionized iron emission (Fe XXV at ) characterizing the Galactic ridge X-ray emission (GRXE) remains a fundamental puzzle in high-energy a…
The orbital period and inclination of the neutron star X-ray transient MAXI J1807+132
E. A. Saavedra, T. Muñoz-Darias, M. A. P. Torres +7
The neutron star X-ray transient MAXI J1807+132 has undergone outbursts in 2017, 2019, and 2023. We conducted an -band time series photometry campaign using the Isaac Newton Tel…
State-dependent signatures of jets and winds in the optical and infrared spectrum of the black hole transient GX 3394
A. Ambrifi, D. Mata Sánchez, T. Muñoz-Darias +14
GX 3394 is one of the prototypical black hole X-ray transients, exhibiting recurrent outbursts that allow detailed studies of black hole accretion and ejection phenomena. In thi…
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…
Fast infrared winds during the radio-loud and X-ray obscured stages of the black hole transient GRS 1915+105
J. Sánchez-Sierras, T. Muñoz-Darias, S. E. Motta +10
The black hole transient GRS 1915+105 entered a new phase of activity in 2018, generally characterised by low X-ray and radio fluxes. This phase has been only interrupted by episod…
Evidence for a black hole in the historical X-ray transient A 1524-61 (=KY TrA)
I. V. Yanes-Rizo, M. A. P. Torres, J. Casares +5
We present VLT spectroscopy, high-resolution imaging and time-resolved photometry of KY TrA, the optical counterpart to the X-ray binary A 1524-61. We perform a refined astrometry…
