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…
ATLAS100 -- I. A volume-limited sample of supernovae and related transients within 100 Mpc
Shubham Srivastav, Stephen J. Smartt, Thomas Moore +29
We present ATLAS100 -- a sample of 1729 supernovae and other explosive optical transients within Mpc observed by the ATLAS survey over a span of 5.75 years from 2017 Sep…
An unexpected population of quenched galaxies harbouring under-massive SMBHs revealed by tidal disruption events
Paige Ramsden, Sean L. McGee, Matt Nicholl
Restricted by event horizon suppression, tidal disruption events (TDEs) provide a unique window into otherwise hidden supermassive black holes (SMBHs) at the lower end of the mass…
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…
MUSE IFU observations of galaxies hosting Tidal Disruption Events
M. Pursiainen, G. Leloudas, J. Lyman +14
We present an analysis of twenty tidal disruption event (TDE) host galaxies observed with the MUSE integral-field spectrograph on ESO VLT. We investigate the presence of extended e…
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…
The case of AT2022wtn: a Tidal Disruption Event in an interacting galaxy
F. Onori, M. Nicholl, P. Ramsden +35
We present the results from our multi-wavelength monitoring campaign of the transient AT2022wtn, discovered by the Zwicky Transient Facility in the nucleus of SDSSJ232323.79+104107…
Quasi-periodic X-ray eruptions years after a nearby tidal disruption event
M. Nicholl, D. R. Pasham, A. Mummery +61
Quasi-periodic Eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of galaxies, repeating on timescales of hours to weeks. The mechanism behind these rare systems i…
Double "acct": a distinct double-peaked supernova matching pulsational pair-instability models
C. R. Angus, S. E. Woosley, R. J. Foley +35
We present multi-wavelength data of SN2020acct, a double-peaked stripped-envelope supernova (SN) in NGC2981 at ~150 Mpc. The two peaks are temporally distinct, with maxima separate…
The fast transient AT 2023clx in the nearby LINER galaxy NGC 3799 as a tidal disruption of a very low-mass star
P. Charalampopoulos, R. Kotak, T. Wevers +30
We present an extensive analysis of the optical and UV properties of AT2023clx, the closest TDE to date, that occurred in the nucleus of the interacting LINER galaxy, NGC3799 (z=0.…
SN 2022jli: a type Ic supernova with periodic modulation of its light curve and an unusually long rise
Moore T., Smartt S. J., Nicholl M. +42
We present multi-wavelength photometry and spectroscopy of SN 2022jli, an unprecedented Type Ic supernova discovered in the galaxy NGC 157 at a distance of 23 Mpc. The mu…
AT2022aedm and a new class of luminous, fast-cooling transients in elliptical galaxies
M. Nicholl, S. Srivastav, M. D. Fulton +49
We present the discovery and extensive follow-up of a remarkable fast-evolving optical transient, AT2022aedm, detected by the Asteroid Terrestrial impact Last Alert Survey (ATLAS).…
The bulge masses of TDE host galaxies and their scaling with black hole mass
Paige Ramsden, Daniel Lanning, Matt Nicholl +1
Tidal disruption events (TDEs) provide a means to probe the low end of the supermassive black hole (SMBH) mass distribution, as they are only observable below the Hills mass ($\les…
Systematic light curve modelling of TDEs: statistical differences between the spectroscopic classes
Matt Nicholl, Daniel Lanning, Paige Ramsden +4
With the sample of observed tidal disruption events (TDEs) now reaching several tens, distinct spectroscopic classes have emerged: TDEs with only hydrogen lines (TDE-H), only heliu…
