MeerKAT HI commissioning observations of MHONGOOSE galaxy ESO 302-G014
(2020-09-22)
We present the results of three commissioning HI observations obtained with the MeerKAT radio telescope. These observations make up part of the preparation for the forthcoming MHONGOOSE nearby galaxy survey, which is a ...
Variations in the Star Formation Efficiency of the Dense Molecular Gas across the Disks of Star-Forming Galaxies
(2015-10)
We present a new survey of HCN(1-0) emission, a tracer of dense molecular gas, focused on the little-explored regime of normal star-forming galaxy disks. Combining HCN, CO, and infrared (IR) emission, we investigate the ...
High-resolution mass models of dwarf galaxies from LITTLE THINGS
(2015-06)
We present high-resolution rotation curves and mass models of 26 dwarf galaxies from LITTLE THINGS. LITTLE THINGS is a high-resolution Very Large Array HI survey for nearby dwarf galaxies in the local volume within 11 Mpc. ...
Estimating the star formation rate at 1 kpc scales in nearby galaxies.
(2012-07)
Using combinations of H alpha, ultraviolet (UV), and infrared (IR) emission, we estimate the star formation rate (SFR) surface density, Sigma(SFR), at 1 kpc resolution for 30 disk galaxies that are targets of the IRAM ...
Low CO luminosities in dwarf galaxies
(2012-05-07)
We present maps of (12)COJ = 2-1 emission covering the entire star-forming disks of 16 nearby dwarf galaxies observed by the IRAM HERACLES survey. The data have 13 '' angular resolution, similar to 250 pc at our average ...
H I in galactic disks
(Cambridge University Press, 2009)
Studies of the atomic phase of the interstellar medium, via the 21-cm spectral line of neutral hydrogen (H I), play a key role in our attempts to understand the structure and evolution of disk galaxies. We present here ...
