The main focus of my current research is in the study of galaxy
formation and evolution in the Epoch of Reionization ; focusing on the
discovery of high redshift galaxies and quasars powered by
the accretion of matter onto
supermassive black holes.
I work on the determination of the
space densities, star formation rates and how and when galaxies and
quasars form. In the past I have worked on the experimental
determination of the rate of gravitational deceleration of the
Universe. This work resulted in the unexpected discovery that the rate
of expansion of the
Universe was accelerating.
My current research focuses on the discovery and study of
high redshift galaxies and quasars
that contain supermassive (100-1000 million Solar mass)
black holes; determining how
their space density, star formation and accretion properties
evolve with redshift; and using the
quasars to probe the baryonic content of the Universe via intervening
absorption lines from H, C, N, O. My group has
pioneered the use of high redshift quasars to determine the mass of
neutral hydrogen in the high redshift Universe via intervening
absorption lines imprinted on the spectra of background
high redshift quasars. I
have also pioneered the use of mm and submm microwave radiation to
determine the star formation rate in quasar host galaxies.
I am the Principal Investigator (PI) of the VISTA Hemisphere
Survey(VHS) which is an ambitious new near
Infra-Red sky survey project which
started in April, 2010. VHS has been been awarded around 300
clear nights over a 5 year period on the new 4.2m ESO VISTA telescope
in Chile. I lead the quasar science working group in the Dark Energy
Survey (DES) project which has built the largest CCD camera in existence
and has been awarded 500 nights on the CTIO 4m telescope in Chile to use
this camera to observe at optical wavelengths part of the sky that will be
surveyed in the near Infra-Red with the VISTA Hemisphere Survey. I am
also working on the 4MOST project which is designing a wide field
spectroscopic instrument for the VISTA telescope. Other projects that
I am active in the SDSS-III
Baryon Oscillation Spectroscopic Survey (BOSS) project and
the ESA satellite mission
