AT 2024qfm: a luminous fast blue optical transient at a redshift of z = 0.2267 identified by Lasair-ZTF
M. Fulton, S. J. Smartt, S. Srivastav +20
Luminous fast blue optical transients (LFBOTs) emit from x-ray to radio wavelengths, epitomised by the discovery of AT 2018cow in a host galaxy at 65 Mpc. In the following eight ye…
The Wandering Supermassive Black Hole Powering the off-nuclear TDE AT2024tvd
M. Guolo, A. Mummery, S. van Velzen +11
We present an analysis of the spectral energy distribution (SED) of the off-nuclear tidal disruption event (TDE) AT2024tvd during its late-time plateau phase, combining X-ray spect…
Can tidal disruption event models reliably measure black hole masses?
C. R. Angus, A. J. Smith, D. Magill +15
Tidal disruption event (TDE) light curves are increasingly used to infer the masses of quiescent supermassive black holes (), offering a powerful probe of low-mass bla…
Normal or transitional? The evolution and properties of two type Ia supernovae in the Virgo cluster
L. Izzo, C. Gall, N. Khetan +47
Type Ia supernovae (SNe Ia) are among the most precise cosmological distance indicators used to study the expansion history of the Universe. The vast increase of SN Ia data due to…
Pan-STARRS follow-up of the gravitational-wave event S250818k and the lightcurve of SN 2025ulz
J. H. Gillanders, M. E. Huber, M. Nicholl +30
Kilonovae are the scientifically rich, but observationally elusive, optical transient phenomena associated with compact binary mergers. Only a handful of events have been discovere…
The radio flare and multi-wavelength afterglow of the short GRB 231117A: energy injection from a violent shell collision
G. E. Anderson, G. P. Lamb, B. P. Gompertz +64
We present the early radio detection and multi-wavelength modeling of the short gamma-ray burst (GRB) 231117A at redshift . The Australia Telescope Compact Array automatic…
