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...

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.
7 Δεκ 1999 · We present early-time infrared (IR) and optical spectroscopy, and optical photometry, of the Type Ia supernova 1994D. These observations provide the most complete optical-IR spectral coverage ever …
Most astronomers measure the wavelength of IR radiation in microns (µm), or millionths of a meter. A human hair, for example, is about 70 µm wide. The visible spectrum extends from about 0.4 µm (violet) to 0.7 µm (red), and the infrared spans the broad region up to hundreds of microns. The infrared region can be further segmented into three ...
