The Environmental Dependence of Galaxy Evolution
(University of Hertfordshire, 2013-12-10)
Observations of galaxy environments have revealed numerous correlations associated
with their intrinsic properties. It is therefore clear that if we are to understand the
processes by which galaxies form and evolve, we ...
Studies of Metal Poor T Dwarfs in UKIDSS
(University of Hertfordshire, 2013-07-31)
I have used blue near-infrared colours to select a group of UKIDSS T dwarfs with spectral
types later than T4. From amongst these I identify two kinematic halo T-dwarf candi-
dates. Blue near-infrared colours have been ...
Formation of Stars and Star Clusters in Colliding Galaxies
(2013-04-03)
Mergers are known to be essential in the formation of large scale structures and to have a
significant role in the history of galaxy formation and evolution. Besides a morphological
transformation, mergers induce important ...
