The Gas Phase in a Low Metallicity ISM
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 ...
THINGS: The HI Nearby Galaxy Survey
We present “The HI Nearby Galaxy Survey (THINGS)”, a high spectral (≤5.2 kms−1) and spatial (~ 6′′) resolution survey of HI emission in 34 nearby galaxies obtained using the NRAO Very Large Array (VLA). The overarching ...
The star formation efficiency in nearby galaxies : measuring where gas forms stars effectively
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 ...
