Ultraluminous X-ray sources in the first eROSITA survey I. Candidate catalogs

P. Weber, T. P. Roberts, S. Hämmerich +28

Ultraluminous X-ray sources (ULXs) are luminous non-nuclear X-ray point sources embedded in galaxies. Their luminosities exceeding 10^39 erg/s potentially require sub-Eddington acc…

A phase-coherent timing solution for the X-ray dim isolated neutron star eRASSU J131716.9-402647

J. Kurpas, A. M. Pires, A. D. Schwope +2

Based on its predominantly thermal X-ray emission and long spin period, the isolated neutron star eRASSU J131716.9-402647 is one of the most promising candidates for membership in…

Isolated neutron star candidates from the fourth generation XMM-Newton catalogues

Adriana M. Pires, Christian Motch, Jan Kurpas +9

X-ray thermally emitting isolated neutron stars (XINSs) are a rare population that provides insights into neutron star cooling, magnetic-field evolution, and Galactic demographics.…

Pulsar scintillation studies with LOFAR III. Annual variations in PSR~J08147429

Yanqing Cai, Ziwei Wu, Weiwei Zhu +27

The interstellar scintillation observed in radio pulsars arises from interference between electromagnetic waves scattered by electron density fluctuations in the turbulent interste…

Multi-epoch afterglow rebrightenings in GRB 250129A: Evidence for successive shock interactions

D. Akl, S. Antier, H. Koehn +105

Most long gamma-ray bursts (GRBs) exhibit afterglows broadly consistent with external forward-shock emission, typically described by smooth broken power-law decays in the multiband…

A comprehensive catalogue of high-mass X-ray binaries in the Large Magellanic Cloud detected during the first eROSITA all-sky survey

D. Kaltenbrunner, C. Maitra, F. Haberl +9

The Magellanic Clouds, the closest star-forming galaxies to the Milky Way, offer an excellent environment to study high-mass X-ray binaries. While the Small Magellanic Cloud has be…
