The DESI Transients Survey: Legacy Classifications and Methodology
Xander J. Hall, Antonella Palmese, Segev BenZvi +56
We present the first systematic spectroscopic observations of extragalactic transients from the Dark Energy Spectroscopic Instrument (DESI), as part of the DESI Transients Survey p…
Early results in the search for extreme coronal line emitters with the Dark Energy Spectroscopic Instrument
Peter Clark, Joseph Callow, Or Graur +44
Here we present the results of our search through the Early Data Release (EDR) of the Dark Energy Spectroscopic Instrument (DESI) for extreme coronal line emitters (ECLEs) - a rare…
AT2025ulz and S250818k: Leveraging DESI spectroscopy in the hunt for a kilonova associated with a sub-solar mass gravitational wave candidate
Xander J. Hall, Antonella Palmese, Brendan O'Connor +47
On August 18th, 2025, the LIGO--Virgo--KAGRA collaboration reported a sub-threshold gravitational wave candidate detection consistent with a sub-solar-mass neutron star merger, den…
The rate of extreme coronal line emitters in the Baryon Oscillation Spectroscopic Survey LOWZ sample
Joseph Callow, Or Graur, Peter Clark +30
Extreme coronal line emitters (ECLEs) are a rare class of galaxy that exhibit strong, high-ionization iron coronal emission lines in their spectra. In some cases, these lines are t…
Candidate strongly lensed type Ia supernovae in the Zwicky Transient Facility archive
A. Townsend, J. Nordin, A. Sagués Carracedo +61
Gravitationally lensed type Ia supernovae (glSNe Ia) are unique astronomical tools that can be used to study cosmological parameters, distributions of dark matter, the astrophysics…
The rate of extreme coronal line emitting galaxies in the Sloan Digital Sky Survey and their relation to tidal disruption events
Joseph Callow, Or Graur, Peter Clark +27
High-ionization iron coronal lines (CLs) are a rare phenomenon observed in galaxy and quasi-stellar object spectra that are thought to be created by high-energy emission from activ…
