The role of the host galaxy kinematics on nuclear activity

, 2008
We investigate the kinematic properties of the stars and ionised gas in the circumnuclear regions of a matched sample of nearby Seyfert and non-active galaxies, using the SAURON Integral-Field Unit (IFU) on the William Herschel Telescope (WHT).

The Void Galaxy Survey

, 2011
The Void Galaxy Survey (VGS) is a multi-wavelength program to study similar to 60 void galaxies. Each has been selected from the deepest interior regions of identified voids in the SDSS redshift survey on the basis of a unique geometric technique, with ...

The role of host galaxy kinematics in nuclear activity

, 2007
Most bulge-dominated galaxies host a supermassive black hole and yet ongoing nuclear activity is observed in only ~5% of nearby galaxies. Reignition of dormant black holes is therefore required and a key unanswered question is whether the ignition ...

The empirical laws of galaxy dynamics: from gas kinematics to weak lensing

Galaxies obey a set of strict dynamical laws, which imply a close coupling between the visible matter (stars and gas) and the observed dynamics (set by dark matter in the standard cosmological context). Here we review recent results from weak gravitational lensing, which allows studying the empirical laws of galaxy dynamics out to exceedingly large ...

Galaxy dynamics in clusters

, 1995
We use high resolution simulations to study the formation and distribution of galaxies within a cluster which forms hierarchically. We follow both dark matter and a gas component which is subject to thermal pressure, shocks, and radiative cooling. Galaxy

Kinematics and dynamics pf giant stars in the solar neighbourhood

, 2004
We study the motion of giant stars in the Solar neighbourhood and what they tell us about the dynamics of the Galaxy: we thus contribute to the huge project of understanding the structure and evolution of the Galaxy as a whole.

Kinematics and simulations of the stellar stream in the halo of the umbrella galaxy

, 2018
We study the dynamics of faint stellar substructures around the Umbrella Galaxy, NGC 4651, which hosts a dramatic system of streams and shells formed through the tidal disruption of a nucleated dwarf elliptical galaxy.
