The Physics of the Nebular Phase in Black Hole X-ray Binaries: Modelling V404 Cygni
A. Ambrifi, T. Muñoz-Darias, J. A. Fernández-Ontiveros +3
Some of the most extreme galactic black hole transients exhibit a nebular phase at the end of their outbursts. This stage was first identified in the 2015 outburst of V404 Cygni, w…
Superorbital variability in the quiescent black hole X-ray transient A0620-00
Enzo A. Saavedra, Roi Alonso, Teo Muñoz-Darias +10
Quiescent black hole low-mass X-ray binaries provide a key setting for probing accretion physics at low luminosities. A0620-00, the archetypal system in this class, has remained in…
Resolving SLX 1744-299 and SLX 1744-300 in the hard X-ray band: implications for their ultracompact nature
Enzo A. Saavedra, Montserrat Armas Padilla, Teo Muñoz-Darias
Persistent, low-luminosity low-mass X-ray binaries (LMXBs) offer a unique opportunity to study accretion in this poorly understood regime, as well as to unveil new members of the u…
Dense, multi-phase accretion disk atmosphere in the low-luminosity state of black hole transientV4641 Sgr
Zuobin Zhang, Rob Fender, James H. Matthews +11
We present soft X-ray spectroscopy of the black-hole X-ray binary V4641~Sgr with the \textit{XMM-Newton} Reflection Grating Spectrometer (RGS). The RGS spectrum shows narrow emissi…
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 NuSTAR view of Ultra-Compact X-ray Binaries
A. Borghese, M. Armas Padilla, T. Muñoz-Darias
Ultra-compact X-ray binaries (UCXBs) are a subclass of low-mass X-ray binaries (LMXBs) characterised by tight orbits and hydrogen-poor donor stars. We present a spectral and timing…
A high-resolution X-ray view of the ultra-fast outflow in MAXI J1810-222
C. Pinto, M. Del Santo, A. D'Aì +10
In previous work, it was reported that the Galactic black hole candidate MAXI J1810-222 exhibited a notable absorption spectral feature at around 1 keV in low-resolution X-ray spec…
A search for optical counterparts in quiescent black hole X-ray transients
I. V. Yanes-Rizo, J. Casares, M. A. P. Torres +7
Dynamical mass measurements of compact stars in X-ray transients demand the detection of optical/near infrared counterparts in quiescence. Out of the 73 black-hole candidates in X-…
Ubiquitous yet forgotten: broad absorptions in the optical spectra of low-mass X-ray binaries
D. Mata Sanchez, T. Munoz-Darias, J. Casares +2
Optical outburst spectra of low-mass X-ray binaries enable studies of extreme accretion and ejection phenomena. While some of their spectroscopic features have been analysed in det…
Accretion disc winds in X-ray binaries
Teo Muñoz-Darias, María Díaz Trigo, Chris Done +2
Despite early theoretical expectations that large-scale, massive outflows would be triggered by accretion onto black holes and neutron stars, their presence was not firmly establis…
