Discovery of a radio-flaring M dwarf in a commensal transient search of the LADUMA field
Moses Mlangeni, Patrick A. Woudt, Paul J. Groot +11
We report the discovery and characterisation of MKT J032848.4-271904.6, a new radio transient identified in the LADUMA field using SARAO Science Data Processor (SDP) UHF-band image…
A Faint Progenitor System for the Faint Supernova 2024vjm
Erez A. Zimmerman, Avishay Gal-Yam, Paul J. Groot +68
Type Ia Supernovae (SNe Ia) are well known for their role as standardizable cosmological candles. Their uniformity is credited to their single origin as thermonuclear explosions of…
A catalog to unite them all: REGALADE, a revised galaxy compilation for the advanced detector era
Hugo Tranin, Nadejda Blagorodnova, Marco A. Gómez-Muñoz +10
Many applications in transient science, gravitational wave follow-up, and galaxy population studies require all-sky galaxy catalogs with reliable distances, extents, and stellar ma…
Textual interpretation of transient image classifications from large language models
Fiorenzo Stoppa, Turan Bulmus, Steven Bloemen +4
Modern astronomical surveys deliver immense volumes of transient detections, yet distinguishing real astrophysical signals (for example, explosive events) from bogus imaging artefa…
The kangaroo's first hop: the early fast cooling phase of EP250108a/SN 2025kg
Rob A. J. Eyles-Ferris, Peter G. Jonker, Andrew J. Levan +52
Fast X-ray transients (FXTs) are a rare and poorly understood population of events. Previously difficult to detect in real time, the launch of the Einstein Probe with its wide fiel…
Hertzsprung gap stars in nearby galaxies and the Quest for Luminous Red Novae Progenitors
Hugo Tranin, Nadejda Blagorodnova, Viraj Karambelkar +5
After the main sequence phase, stars more massive than 2.5 M rapidly evolve through the Hertzsprung gap as yellow giants and supergiants (YSG), before settling into the red…
