Radio AGN in spiral galaxies
(2015-12-01)
Radio AGN in the nearby Universe are more likely to be found in galaxies with early-type morphology, the detection rate in spiral or late-type galaxies (LTGs) being around an order of magnitude lower. We combine the mJy ...
The triggering of local AGN and their role in regulating star formation
(2015-09-01)
We explore the processes that trigger local AGN and the role of these AGN in regulating star formation, using ~350 nearby galaxies observed by the mJy Imaging VLBA Exploration at 20cm (mJIVE) survey. The >10^7 K brightness ...
Molecular and atomic gas in dust lane early-type galaxies - I : Low star-formation efficiencies in minor merger remnants
(2015-06-01)
In this work we present IRAM-30m telescope observations of a sample of bulge-dominated galaxies with large dust lanes, which have had a recent minor merger. We find these galaxies are very gas rich, with H2 masses between ...
An infrared study of local galaxy mergers
(2015-05-13)
We combine a large, homogeneous sample of $\sim$3000 local mergers with the Imperial IRAS Faint Source Redshift Catalogue (IIFSCz), to perform a blind far-infrared (FIR) study of the local merger population. The IRAS-detected ...
Galaxy Zoo : the dependence of the star formation-stellar mass relation on spiral disk morphology
(2015-03-19)
We measure the stellar mass-star formation rate relation in star-forming disk galaxies at z1. Of the galaxies lying significantly above the M-SFR relation in the local Universe, more than 50% are mergers. We interpret this ...
