Angular momentum evolution of galaxies in EAGLE
Claudia del P. Lagos, Tom Theuns, Adam R. H. Stevens +5
We use the EAGLE cosmological hydrodynamic simulation suite to study the specific angular momentum of galaxies, , with the aims of (i) investigating the physical causes behind t…
Spatially resolved variations of the IMF mass normalisation in early-type galaxies as probed by molecular gas kinematics
Timothy A. Davis, Richard M. McDermid
We here present the first spatially-resolved study of the IMF in external galaxies derived using a dynamical tracer of the mass-to-light ratio. We use the kinematics of relaxed mol…
Star Formation in Nearby Early-Type Galaxies: The Radio Continuum Perspective
Kristina Nyland, Lisa M. Young, Joan M. Wrobel +9
We present a 1.4 GHz Karl G. Jansky Very Large Array (VLA) study of a sample of early-type galaxies (ETGs) from the volume- and magnitude-limited ATLAS-3D survey. The radio morphol…
Molecular Gas Kinematics and Line Diagnostics in Early-type Galaxies: NGC4710 and NGC5866
Selcuk Topal, Martin Bureau, Timothy A. Davis +3
We present interferometric observations of CO lines (12CO(1-0, 2-1) and 13CO(1-0, 2-1)) and dense gas tracers (HCN(1-0), HCO+(1-0), HNC(1-0) and HNCO(4-3)) in two nearby edge-on ba…
Delayed triggering of radio Active Galactic Nuclei in gas-rich minor mergers in the local Universe
Stanislav Shabala, Adam Deller, Sugata Kaviraj +5
We examine the processes triggering star formation and Active Galactic Nucleus (AGN) activity in a sample of 25 low redshift () gas-rich galaxy mergers observed at milli-ar…
The Tully-Fisher Relation of COLD GASS Galaxies
Alfred L. Tiley, Martin Bureau, Amélie Saintonge +3
We present the stellar mass (M_*) and Wide-Field Infrared Survey Explorer (WISE) absolute Band 1 magnitude (M_W1) Tully-Fisher relations (TFRs) of subsets of galaxies from the CO L…
Cold, clumpy accretion onto an active supermassive black hole
Grant R. Tremblay, J. B. Raymond Oonk, Françoise Combes +22
Supermassive black holes in galaxy centres can grow by the accretion of gas, liberating energy that might regulate star formation on galaxy-wide scales. The nature of the gaseous f…
The Atlas3D project -- XXXI. Nuclear radio emission in nearby early-type galaxies
Kristina Nyland, Lisa M. Young, Joan M. Wrobel +22
We present the results of a high-resolution, 5 GHz, Karl G. Jansky Very Large Array study of the nuclear radio emission in a representative subset of the Atlas3D survey of early-ty…
