Time-varying double-peaked emission lines following the sudden ignition of the dormant galactic nucleus AT2017bcc
E. J. Ridley, M. Nicholl, C. A. Ward +35
We present a pan-chromatic study of AT2017bcc, a nuclear transient that was discovered in 2017 within the skymap of a reported burst-like gravitational wave candidate, G274296. It…
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…
GW190425: Pan-STARRS and ATLAS coverage of the skymap and limits on optical emission associated with FRB190425
S. J. Smartt, M. Nicholl, S. Srivastav +32
GW190425 is the second of only two binary neutron star (BNS) merger events to be significantly detected by the LIGO-Virgo- Kagra gravitational wave detectors. With a detection only…
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).…
A Precursor Plateau and Pre-Maximum [O II] Emission in the Superluminous SN2019szu: A Pulsational Pair-Instability Candidate
Aysha Aamer, Matt Nicholl, Anders Jerkstrand +29
We present a detailed study on SN2019szu, a Type I superluminous supernova at , that displayed unique photometric and spectroscopic properties. Pan-STARRS and ZTF forced p…
Polarimetry of Hydrogen-Poor Superluminous Supernovae
M. Pursiainen, G. Leloudas, A. Cikota +11
We present linear polarimetry for seven hydrogen-poor superluminous supernovae (SLSNe-I). For SN 2017gci, for which we present two epochs of spectropolarimetry at +3 d and +29 d po…
