A soft and transient ultraluminous X-ray source with 6-h modulation in the NGC 300 galaxy
A. Sacchi, P. Esposito, D. de Martino +13
We investigate the nature of CXOU J005440.5-374320 (J0054), a peculiar bright ( erg/s) and soft X-ray transient in the spiral galaxy NGC 300 with a 6-hour per…
A helium-burning white dwarf binary as a supersoft X-ray source
J. Greiner, C. Maitra, F. Haberl +12
Type Ia supernovae are cosmic distance indicators, and the main source of iron in the Universe, but their formation paths are still debated. Several dozen supersoft X-ray sources,…
The 2019 outburst of AMXP SAX J1808.4-3658 and radio follow up of MAXI J0911-655 and XTE J1701-462
K. V. S. Gasealahwe, I. M. Monageng, R. P. Fender +14
We present radio coverage of the 2019 outburst of the accreting millisecond X-ray pulsar SAX J1808.4-3658, obtained with MeerKAT. We compare these data to contemporaneous X-ray and…
SRG/eROSITA-triggered XMM-Newton observations of three Be/X-ray binaries in the LMC: Discovery of X-ray pulsations
F. Haberl, C. Maitra, D. Kaltenbrunner +11
Using data from eROSITA, the soft X-ray instrument aboard Spectrum-Roentgen-Gamma (SRG), we report the discovery of two new hard transients, eRASSU J050810.4-660653 and eRASSt J044…
The triple-peaked afterglow of GRB 210731A from X-ray to radio frequencies
S. de Wet, T. Laskar, P. J. Groot +18
GRB 210731A was a long-duration gamma-ray burst discovered by the Burst Alert Telescope (BAT) aboard the Neil Gehrels Swift observatory. Swift triggered the wide-field, robotic Mee…
Hot white dwarfs and pre-white dwarfs discovered with SALT
C. S. Jeffery, K. Werner, D. Kilkenny +3
The Southern African Large Telescope (SALT) survey of helium-rich hot subdwarfs aims to explore evolutionary pathways amongst groups of highly-evolved stars. The selection criteria…
