Probing evolutionary mechanisms in galaxy clusters: H I in Abell 1367
(2009)
We are carrying out a programme of CO and interferometric H I observations in the nearby galaxy cluster Abell 1367. The aim is to better understand the processes driving the evolution of the ISM in late-type galaxies in ...
Triggered star formation and the creation of the supergiant HI shell in IC 2574
(2009)
Based on deep imaging from the Advanced Camera for Surveys aboard the Hubble Space Telescope (HST), we present new evidence that stellar feedback created a similar to 1 kpc supergiant Hi shell (SGS) and triggered star ...
Collisional Debris as Laboratories to Study Star Formation
(2009)
In this paper we address the question of whether star formation (SF) is driven by local processes or the large-scale environment. To do so, we investigate SF in collisional debris where the gravitational potential well and ...
The Gas Phase in a Low Metallicity ISM
(2008)
We present several results from our analysis of dwarf irregular galaxies culled from The HI Nearby Galaxy Survey (THINGS). We analyse the rotation curves of two galaxies based on “bulk” velocity fields, i.e. velocity maps ...
The star formation efficiency in nearby galaxies : measuring where gas forms stars effectively
(2008)
We measure the star formation efficiency (SFE), the star formation rate (SFR) per unit of gas, in 23 nearby galaxies and compare it with expectations from proposed star formation laws and thresholds.We use Hi maps from The ...
