Decadal pre-explosion activity and circumstellar interaction in a supernova

Ting-Wan Chen, Amar Aryan, Sheng Yang +52

When a massive star explodes as a supernova, crucial information about its immediate environment is lost within hours. Here we report rapid optical observations from Lulin Observat…

The transitional Type Ibn/IIn SN 2022pda, with pre-explosion outbursts and a double-peaked light curve

Y. -Z. Cai, A. Pastorello, R. Chiba +65

We report the results of a photometric and spectroscopic follow-up campaign of the unusual interacting supernova (SN) 2022pda. Precursor variability lasting days is obse…

SCAT Data Release 1: 1812 optical spectra of 1331 transients

Michael A. Tucker, Mark E. Huber, Benjamin J. Shappee +19

We present the first data release (DR1) of the Spectroscopic Classification of Astronomical Transients (SCAT) survey, covering the first years of observations (March 20…

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…

An Archival Optical Counterpart Search for Extragalactic Fast X-Ray Transients Discovered by Einstein Probe

Run-Duo Liang, Wen-Xiong Li, Liang-Duan Liu +50

Extragalactic fast X-ray transients (eFXTs) represent a rapidly growing class of high-energy phenomena, whose physical origins remain poorly understood. With its wide-field, sensit…

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…
