Infrared to millimetre observations of active galaxies
… data are described. The central 1.5 kpc of the starburst galaxy M82 was mapped at 800 and 1100pm. The far-infrared (FIR) to millimetre continuum is due to thermal reradiation from dust grains at a temperature of 47 K, and the spatial distribution of the thermal emission shows a halo of grains …

LUMINOSITY DISTRIBUTIONS AND ABUNDANCE TOMOGRAPHY MODELLING OF TYPE IA SUPERNOVAE
… B and V - band light curves, separated by host galaxy type. A new method for calculating host galaxy extinction is implemented and the width luminosity relation (WLR) is examined. After correction for host galaxy extinction, ‘normal’ SNe Ia (∆m15(B) < 1.6 mag) fill a larger parameter space in …

Millimetre and Submillimetre continuum imaging studies of nearby active galaxies
… The observations of Cygnus A constrained the galaxy's cold dust temperature between 37 and 85K, corresponding to dust masses between 1.0 x 10 8M® and 1.4 x 106M® respectively. Based on the dust spatial and mass limits, it is possible the heating of the cold dust in Cygnus A is dominated by …

Magneto-centrifugal Wind with Applications to Astrophysical Accretion Disks
We calculate the structure of radially self-similar magneto-centrifugal winds with a wide range of magnetic flux distribution, mass loading, and injection speed at the base of the wind. A variety of wind structures is obtained, including winds driven by magneto-centrifugal and magnetic pressure …

Supernovae as gamma ray emitters from the MeV to the TeV
… these two aspects of supernovae. (1) Both starburst galaxies and ultra luminous infrared galaxies are new gamma-ray source classes discovered by Fermi and TeV telescopes. These extreme star-forming galaxies have high supernova rates, and thus accelerating cosmic rays that collide with dense …
