Welcome to the home page of the Extragalactic Team here at the Mullard Space Science Laboratory. These pages are intended to provide information for other researchers and for interested members of the public alike. For anyone unfamiliar with the subject of Active Galactic Nuclei or `AGN' (which include Seyfert galaxies and quasars), try the Beginner's Guide for a brief description of what these fantastic objects are.
OUR MAJOR TOPICS OF INTEREST ARE:
QUASARS
SEYFERT GALAXIES
NARROW EMISSION LINE GALAXIES
X-RAY BACKGROUND
EXTRAGALACTIC SUB-MM AND IR ASTRONOMY
Current Areas of Research:
Population
Studies of Active Galactic Nuclei:
probing the structure and geometry
of Seyfert 1s and quasars
X-ray Evolution
of AGN:
looking back in time. to measure how
the number of AGN and their brightness in X-rays have evolved
Ultra-soft
X-ray AGN:
high temperature emission from the nucleus
Narrow Emission
Line Galaxies:
starburst galaxies and `mini' Seyfert nuclei
Submm/IR Astronomy:
Measurements of the Cosmic Microwave Background and submm/IR emission
from galaxies and quasars.
More general information about quasars and Seyfert galaxies may be found in the following pages:
