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 ...
THINGS: The HI Nearby Galaxy Survey
(2008)
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 ...
Are the kinematics of DLAs in agreement with their arising in the gas disks of galaxies?
(2008)
We demonstrate in this paper that the velocity widths of the neutral gas in damped Lyα (DLA) systems are inconsistent with these systems originating in gas disks of galaxies, similar to those seen in the local universe. ...
High-resolution rotation curves and galaxy mass models from THINGS
(2008)
We present rotation curves of 19 galaxies from The H I Nearby Galaxy Survey (THINGS). The high spatial and velocity resolution of THINGS make these the highest quality H I rotation curves available to date for a large ...
