The Stellar and Gas Kinematics of the LITTLE THINGS Dwarf Irregular Galaxy NGC 1569
(2012-11)
In order to understand the formation and evolution of Magellanic-type dwarf irregular (dIm) galaxies, one needs to understand their three-dimensional structure. We present measurements of the stellar velocity dispersion ...
BASIS: Bayfordbury single-object integral field spectrograph
(SPIE, 2012-09)
We present an inexpensive (<US$500) and easily replicable integral field unit for use on small aperture telescopes. Based on a commercial small spectrograph (SBIG Self-Guiding Spectrograph) and a 37 optical fibre bundle ...
The JCMT Nearby Galaxies Legacy Survey - VIII : CO data and the L -L correlation in the SINGS sample
(2012-08-21)
The James Clerk Maxwell Telescope Nearby Galaxies Legacy Survey (NGLS) comprises an Hi-selected sample of 155 galaxies spanning all morphological types with distances less than 25Mpc. We describe the scientific goals of ...
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 ...
Two long HI tails in the outskirts of Abell 1367
(2012-01-01)
We present VLA D-array Hi observations of the RSCG42 and FGC1287 galaxy groups, in the outskirts of the Abell 1367 cluster. These groups are projected ∼1.8 and 2.7Mpc west from the cluster centre. The Arecibo Galaxy ...
Deep radio continuum imaging of the dwarf irregular galaxy IC 10: tracing star formation and magnetic fields
(2011-09-20)
We exploit the vastly increased sensitivity of the Expanded Very Large Array to study the radio continuum and polarization properties of the post-starburst, dwarf irregular galaxy IC 10 at 6 cm, at a linear resolution of ...
H I asymmetries in the isolated galaxy CIG 292
(2011-09-20)
We present Expanded Very Large Array (EVLA) D-array observations of the 21 cm line of neutral hydrogen (H-I) of CIG 292, an isolated SA(s)b galaxy at a distance of similar to 24.3 Mpc. From previous Hi single dish observations ...
Studying the spatially resolved Schmidt-Kennicutt law in interacting galaxies : The case of Arp 158
(2011-09)
Context. Recent studies have shown that star formation in mergers does not seem to follow the same Schmidt-Kennicutt relation as in spiral disks, presenting a higher star formation rate (SFR) for a given gas column density. ...
VII Zw 403: H I structure in a blue compact dwarf galaxy
(2011-09)
We present optical (UBVJ), ultraviolet (FUV, NUV), and high-resolution atomic hydrogen (H I) observations of the nearby blue compact dwarf (BCD), VII Zw 403. We find that VII Zw 403 has a relatively high H I mass-to-light ...
