ABSTRACT We present Hubble Space Telescope imaging of a pre-explosion counterpart to
SN 2019yvr obtained 2.6 yr before its explosion as a type Ib supernova (SN Ib). Aligning to a …

We present observations of ASASSN-19dj, a nearby tidal disruption event (TDE) discovered
in the post-starburst galaxy KUG 0810+ 227 by the All-Sky Automated Survey for …

We present optical, ultraviolet, and infrared data of the type II supernova (SN II) 2020jfo at
14.5 Mpc. This wealth of multiwavelength data allows us to compare different metrics …

We present GHOST, a database of 16,175 spectroscopically classified supernovae (SNe)
and the properties of their host galaxies. We have constructed GHOST using a novel host …

MAAT is proposed as a visitor mirror-slicer optical system that will allow the OSIRIS
spectrograph on the 10.4-m Gran telescopio CANARIAS (GTC) the capability to perform …

Analyses of type Ia supernovae (SNe Ia) have found puzzling correlations between their
standardised luminosities and host galaxy properties: SNe Ia in high-mass, passive hosts …

Kirsty Taggart Page 1 The environments and progenitors of extreme supernovae in the low-redshift
universe by Kirsty Taggart A thesis submitted in partial fulfilment of the requirements of …

The explosive origin of the young supernova remnant (SNR) 3C 397 (G41. 1-0.3) is debated.
Its elongated morphology and proximity to a molecular cloud are suggestive of a core …

The galaxy Mrk 590 is one of the few known 'changing-look'Active Galactic Nuclei (AGN) to
have transitioned between states twice, having just increased its flux after a period of˜ 10 …
