Searching for electromagnetic emission in an AGN from the gravitational wave binary black hole merger candidate S230922g
Tomás Cabrera, Antonella Palmese, Lei Hu +17
We carried out long-term monitoring of the LIGO/Virgo/KAGRA binary black hole (BBH) merger candidate S230922g in search of electromagnetic emission from the interaction of the merg…
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…
Light-Curve Structure and Halpha Line Formation in the Tidal Disruption Event AT 2019azh
Sara Faris, Iair Arcavi, Lydia Makrygianni +33
AT 2019azh is a H+He tidal disruption event (TDE) with one of the most extensive ultraviolet and optical data sets available to date. We present our photometric and spectroscopic o…
Long-term follow-up observations of extreme coronal line emitting galaxies
Peter Clark, Or Graur, Joseph Callow +40
We present new spectroscopic and photometric follow-up observations of the known sample of extreme coronal line emitting galaxies (ECLEs) identified in the Sloan Digital Sky Survey…
The nuclear transient AT 2017gge: a tidal disruption event in a dusty and gas-rich environment and the awakening of a dormant SMBH
F. Onori, G. Cannizzaro, P. G. Jonker +28
We present the results from a dense multi-wavelength (optical/UV, near-infrared (IR), and X-ray) follow-up campaign of the nuclear transient AT2017gge, covering a total of 1698 day…
Probing the Progenitors of Type Ia Supernovae using Circumstellar Material Interaction Signatures
Peter Clark, Kate Maguire, Mattia Bulla +4
This work aims to study different probes of Type Ia supernova progenitors that have been suggested to be linked to the presence of circumstellar material (CSM). In particular, we h…
SN 2018gjx reveals that some SNe Ibn are SNe IIb exploding in dense circumstellar material
S. J. Prentice, K. Maguire, I. Boian +27
We present the data and analysis of SN 2018gjx, an unusual low-luminosity transient with three distinct spectroscopic phases. Phase I shows a hot blue spectrum with signatures of i…
LSQ13ddu: A rapidly-evolving stripped-envelope supernova with early circumstellar interaction signatures
Peter Clark, Kate Maguire, Cosimo Inserra +30
This paper describes the rapidly evolving and unusual supernova LSQ13ddu, discovered by the La Silla-QUEST survey. LSQ13ddu displayed a rapid rise of just 4.80.9 d to reach a…
SN2018kzr: a rapidly declining transient from the destruction of a white dwarf
Owen R. McBrien, Stephen J. Smartt, Ting-Wan Chen +31
We present SN2018kzr, the fastest declining supernova-like transient, second only to the kilonova, AT2017gfo. SN2018kzr is characterized by a peak magnitude of , peak…
Soft X-Ray Excess from Shocked Accreting Plasma in Active Galactic Nuclei
Keigo Fukumura, Douglas Hendry, Peter Clark +2
We propose a novel theoretical model to describe a physical identity of the soft X-ray excess, ubiquitously detected in many Seyfert galaxies, by considering a steady-state, axisym…
