Photoionization of the Composite Nebula Surrounding NGC 5408 X-1: Implications for Beamed Emission
Jing Guo, Hua Feng, Roberto Soria +4
NGC 5408 X-1 is one of the best studied ultraluminous X-ray sources (ULXs) and is surrounded by a photoionized nebula. Previous optical spectroscopy established the presence of str…
Optical outburst evolution of the transient black hole X-ray binary Swift J1727.8-1613: Disc response to jet ejections and late-outburst emergence of powerful disc winds
N. Castro Segura, K. Solomons, J. M. Corral-Santana +22
Swift J1727.81613 is a newly discovered transient low-mass X-ray binary harbouring a stellar-mass () black hole. We present state-resolved VLT/X-Shooter optical…
Disc Winds From Accreting Systems in the 2040s
Noel Castro Segura, Virginia Cúneo, Francesco Tombesi +9
What does the temporal evolution of disc winds tell us about accreting systems and the accretion process? Studies of accretion-disc outflows across all mass scales, including accre…
On the distance to the black hole X-ray binary Swift J1727.81613
Benjamin J. Burridge, James C. A. Miller-Jones, Arash Bahramian +11
We review the existing distance estimates to the black hole X-ray binary Swift J1727.81613, present new radio and near-UV spectra to update the distance constraints, and discuss…
Characterising the short-orbital period X-ray transient Swift J1910.2-0546
J. M. Corral-Santana, P. Rodriguez-Gil, M. A. P. Torres +13
SwiftJ1910.2-0546 is a Galactic X-ray transient discovered during a bright outburst in 2012. We use time-series optical photometry and spectroscopy to estimate the orbital period,…
Searching for new Hypervelocity Stars with Gaia DR3 and VLT/FORS2 Spectroscopy
Julio A. Carballo-Bello, Pau Ramos, Jesús M. Corral-Santana +5
Hypervelocity stars are unique objects moving through the Milky Way at speeds exceeding the local escape velocity, providing valuable insights into the Galactic gravitational poten…
