Carbon monoxide in clouds at low metallicity in the dwarf irregular galaxy WLM
(2013-03-27)
Carbon monoxide (CO) is the primary tracer for interstellar clouds where stars form, but it has never been detected in galaxies in which the oxygen abundance relative to hydrogen is less than 20 per cent of that of the ...
CO in late-type galaxies within the central region of Abell 1367
(2013-02)
We present 12CO (J = 1→ 0) and 12CO (J = 2 →1) spectra for 19 bright, late–type galaxies (spirals) in the central region of the galaxy cluster Abell 1367 (z = 0.02) from observations make with the IRAM 30–m telescope. All ...
NGC 2207/IC 2163 : A Grazing Encounter with Large-scale Shocks
(2012-11)
Radio continuum, Spitzer infrared, optical, and XMM-Newton X-ray and ultraviolet observations (UVW1 and UVM2) are used to study large-scale shock fronts, young star complexes, and the galactic nuclei in the interacting ...
Little Things
(2012-11)
We present LITTLE THINGS (Local Irregulars That Trace Luminosity Extremes, The H I Nearby Galaxy Survey), which is aimed at determining what drives star formation in dwarf galaxies. This is a multi-wavelength survey of 37 ...
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 ...
