A dust-enshrouded tidal disruption event with a resolved radio jet in a galaxy merger
S. Mattila, M. Pérez-Torres, A. Efstathiou +33
Tidal disruption events (TDEs) are transient flares produced when a star is ripped apart by the gravitational field of a supermassive black hole (SMBH). We have observed a transien…
A population of highly energetic transient events in the centres of active galaxies
E. Kankare, R. Kotak, S. Mattila +25
Recent all-sky surveys have led to the discovery of new types of transients. These include stars disrupted by the central supermassive black hole, and supernovae that are 10-100 ti…
Supernovae and radio transients in M 82
S. Mattila, M. Fraser, S. J. Smartt +4
We present optical and near-infrared (IR) photometry and near-IR spectroscopy of SN 2004am, the only optically detected supernova (SN) in M 82. These demonstrate that SN 2004am was…
Extensive optical and near-infrared observations of the nearby, narrow-lined type Ic SN 2007gr: days 5 to 415
Deborah J. Hunter, Stefano Valenti, Rubina Kotak +26
We present photometric and spectroscopic observations at optical and near-infrared wavelengths of the nearby type Ic SN 2007gr. These represent the most extensive data-set to date…
SN 2008S: an electron capture SN from a super-AGB progenitor?
M. T. Botticella, A. Pastorello, S. J. Smartt +31
We present comprehensive photometric and spectroscopic observations of the faint transient SN 2008S discovered in NGC 6946. SN 2008S exhibited slow photometric evolution and almost…
Massive stars exploding in a He-rich circumstellar medium III. SN 2006jc: IR echoes from new and old dust in the progenitor CSM
S. Mattila, W. P. S. Meikle, P. Lundqvist +9
We present near- and mid-infrared (IR) photometric data of the Type Ibn supernova (SN) 2006jc obtained with the United Kingdom Infrared Telescope (UKIRT), the Gemini North Telescop…
