The unidentified PeV source LHAASO J2108+5157: A microquasar remnant?
Josep Mart\'ı, Pedro L. Luque-Escamilla, Leandro Abaroa +4
Context. LHAASO~J2108+5157 is one of the most intriguing Galactic ultra-high-energy -ray sources. It is detected up to hundreds of TeV but lacks a clear counterpart at lower fre…
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…
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…
Unmasking LHAASO J2108+5157: Near Infrared Insights into a Mysterious TeV Source
Josep Martí, Pedro L. Luque-Escamilla, Josep M. Paredes +1
LHAASO J2108+5157 is one of the few ultra-high energy gamma-ray sources in the LHAASO catalogue without secure counterpart at longer wavelengths. Several Galactic scenarios have be…
A runaway T-Tauri star leaving an extended trail
Josep Martí, Pedro L. Luque-Escamilla, Estrella Sánchez-Ayaso
Aims. We address the problem of young stellar objects that are found too far away from possible star formation sites. Different mechanisms have been proposed before to explain this…
