Prof. Peter Meikle is internationally recognised as a pioneer of the infrared study of supernovae. For over 25 years, he and his team at Imperial College London have carried out infrared investigations of all types of supernovae. This includes late-time spectroscopic studies providing, for example, key evidence for (a) the production of large ...
We have obtained the first mid-IR spectra of any supernova apart from SN 1987A. A prominent [NiII] 6.64 micron line is observed, from which we deduce that the mass of stable nickel must be at...
Signatures of delayed detonation, asymmetry, and electron capture in the mid-infrared spectra of supernovae 2003hv and 2005df
We present early-time near-infrared spectra of the type Ia supernova 1991T and latetime spectra of SNe 1991T and 1987A obtained with IRIS on the AAT and CGS4 on UKIRT. A large mass of iron is present in the ejecta of type Ia supernovae.
Extensive optical and near-infrared observations of the nearby, narrow-lined type Ic SN 2007gr: days 5 to 415
7 Δεκ 1999 · We present first-season infrared (IR) and optical photometry and spectroscopy of the Type Ia Supernova 1998bu in M96. We also report optical polarimetry of this event. SN 1998bu is one of the closest …
The spectroscopic behaviour of Type Ia supernovae before and just after maximum light is of great interest since this covers the time when the photosphere recedes through most of the ejecta. While a number of optical spectra exist for this period, there are only a few early-time infrared spectra.
