A Galactic microblazar as a potential accelerator of ultra-high-energy particles
Josep Martí, Pedro L. Luque-Escamilla, Benito Marcote +10
Context. Persistent jets from X-ray binaries which are aligned very close to the line of sight could be considered to be Galactic equivalents of blazars, or 'microblazars'. They ar…
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…
A candidate proton cyclotron feature in the ultraluminous X-ray source NGC 4656 ULX-1
Nelson Cruz-Sanchez, Enzo A. Saavedra, Federico A. Fogantini +6
Ultraluminous X-ray sources represent extreme super-Eddington accretion regimes, and a subset is now known to host highly magnetized neutron stars. However, direct observational pr…
Constraints on cyclotron features and accretion regime in the high-mass X-ray binary 4U 1700-37 from NuSTAR
Lautaro West-Ocampo, Federico A. Fogantini, Enzo A. Saavedra +6
4U 1700-37 is a wind-fed high-mass X-ray binary hosting a compact object, likely a neutron star, accreting from O6.5 Iaf+ supergiant HD 153919. Coherent pulsations not firmly detec…
