… Following our initial announcement of high velocities in SN 2009ip (Smith & Mauerhan
2012a), two preliminary reports presented optical photometry which was interpreted as indicating …

… SN 2010jp from Smith et al. (2012), the R-band light curve of SN 2005ip (in green; Smith et
al… For comparison, we also show (in blue) the R/unfiltered light curve of SN 2010jp from Smith …

We present photometry and spectroscopy of the Type IIn supernova (SN) 2011ht, identified
previously as a possible SN impostor. The light curve exhibits an abrupt transition from a well-…

… 2011a) in a volume-limited sample of large star-forming galaxies, and there are hints that
they are as common or possibly more common at lower metallicity (see Smith 2014). It is …

… program to study the environment around SN 2009ip (PI Smith, GO-13787) using four filters:
… of the environment around SN 2009ip, see Smith, Andrews & Mauerhan (2016b). We also …

We present optical photometry and spectroscopy of the peculiar Type IIn/Ibn supernova (SN)
2011hw. Its optical light curve exhibits a slower decline rate than that of normal SNe Ibc, …

We present late-time Hubble Space Telescope (HST) images of the site of supernova (SN)
2009ip taken almost 3 yr after its bright 2012 luminosity peak. SN 2009ip is now slightly …

We present low-resolution near-infrared (IR) 0.8–2.5 μm spectra of Supernova (SN) 2009ip,
taken immediately before, during and just after its rapid brightening in late September/…

The Galactic transient V1309 Sco was the result of a merger in a low-mass star system, while
V838 Mon was thought to be a similar merger event from a more massive B-type progenitor…

We present multi-epoch spectropolarimetry of Type IIn supernova SN2017hcc, 16–391 d
after explosion. Continuum polarization up to 6 per cent is observed during the first epoch, …
