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…

AT 2018dyk: tidal disruption event or active galactic nucleus? Follow-up observations of an extreme coronal line emitter with the Dark Energy Spectroscopic Instrument
Peter Clark, Joseph Callow, Or Graur +29
We present fresh insights into the nature of the tidal disruption event (TDE) candidate AT 2018dyk. AT 2018dyk has sparked a debate in the literature around its classification as e…

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…
