My primary research interests centre on the
study of the UV to Gamma-ray emission from
Active Galctic Nuclei (AGN); a
subset of galaxies whose central regions produce copious amounts of
radiation, most likely due to the accretion of matter onto a
"supermassive" black hole (106 to 109
times the mass of the sun).
This work is primarily observational,
involving the reduction & interpretation of satellite data,
including those collected using
EXOSAT,
Ginga,
IUE,
ROSAT,
HST,
ASCA,
RXTE,
BeppoSAX,
CXO,
FUSE,
and
XMM-Newton
missions
(still operational).
My current research can be divided into three broad (but related) areas,
as detailed below.
