Automatically distinguishing Rubin transients from AGN using variability metrics
Dylan Magill, Matt Nicholl, Philip Wiseman +7
Stochastic variability of active galactic nuclei (AGN) can produce contaminants in the search for explosive extragalactic transients (such as supernovae and tidal disruption events…
Testing and Combining Transient Spectral Classification Tools on 4MOST-like Blended Spectra
Andrew Milligan, Isobel Hook, Christopher Frohmaier +15
With the 4-meter Multi-Object Spectroscopic Telescope (4MOST) expected to provide an influx of transient spectra when it begins observations in early 2026 we consider the potential…
Evidence for a steeper SMBH-Bulge mass relationship extended to low masses using TDE host galaxies
Paige Ramsden, Matt Nicholl, Sean L. McGee +1
Tidal disruption events (TDEs) are excellent tools for probing low mass supermassive black holes (SMBHs) that may otherwise remain undetected. Here, we present an extended SMBH--Bu…
EP 250108a/SN 2025kg: Observations of the most nearby Broad-Line Type Ic Supernova following an Einstein Probe Fast X-ray Transient
J. C. Rastinejad, A. J. Levan, P. G. Jonker +66
With a small sample of fast X-ray transients (FXTs) with multi-wavelength counterparts discovered to date, the progenitors of FXTs and their connections to gamma-ray bursts (GRBs)…
Super-SNID : an expanded set of SNID classes and templates for the new era of wide-field surveys
Dylan Magill, Michael D. Fulton, Matt Nicholl +4
We present an expanded template library for the supernova identification (SNID) software, along with updated source files that make it easy to merge our templates - and other major…
The impact of ultraviolet suppression on the rates and properties of strongly lensed Type IIn supernovae detected by LSST
Andrés I. Ponte Pérez, Graham P. Smith, Matt Nicholl +4
Upcoming wide-field time-domain surveys, such as the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) are expected to discover up to two orders of magnitude more…
