The JCMT nearby galaxies legacy survey - V. The CO(J=3-2) distribution and molecular outflow in NGC 4631
(2011)
We have made the first map of CO(J = 3-2) emission covering the disc of the edge-on galaxy, NGC 4631, which is known for its spectacular gaseous halo. The strongest emission, which we model with a Gaussian ring, occurs ...
Environmental effects in galaxy clusters : Infalling groups in Abell 85 and 1367
(2010-12-01)
We are carrying out a multifrequency survey of late type galaxies in nearby clusters with the aim to investigate the effects exerted by both the very local and the global cluster environments. We report new VLA-HI images ...
Dwarf-Galaxy Cosmology
(2010)
Dwarf galaxies provide opportunities for drawing inferences about the processes in the early universe by observing our “cosmological backyard”—the Local Group and its vicinity. This special issue of the open-access journal ...
NGC765-a disturbed HI giant
(2010)
We present H I spectral line and radio-continuum Very Large Array (VLA) data of the galaxy NGC 765, complemented by optical and Chandra X-ray maps. NGC 765 has the largest H I-to-optical ratio known to date of any spiral ...
The JCMT Nearby Galaxies Legacy Survey – III. Comparisons of cold dust, polycyclic aromatic hydrocarbons, molecular gas and atomic gas in NGC 2403
(2010)
We used Spitzer Space Telescope 3.6, 8.0, 70 and 160 μm data, James Clerk Maxwell Telescope HARP-B CO J= (3–2) data, National Radio Astronomy Observatory 12 m telescope CO J= (1–0) data and Very Large Array H i data to ...
Probing evolutionary mechanisms in galaxy clusters: neutral atomic hydrogen in Abell 1367
(2010)
We present Very Large Array H i imaging data for a field in the NW of the galaxy cluster Abell 1367 (z= 0.02) in an attempt to probe the effect environment has on the interstellar medium of late-type spiral galaxies. Several ...
Extremely inefficient star formation in the outer disks of nearby galaxies
(2010)
We combine data from The H I Nearby Galaxy Survey and the GALEX Nearby Galaxy Survey to study the relationship between atomic hydrogen (H I) and far-ultraviolet (FUV) emission outside the optical radius (r 25) in 17 spiral ...
The James Clerk Maxwell Telescope Nearby Galaxies Legacy Survey. II. Warm molecular gas and star formation in three field spiral galaxies
(2010)
We present the results of large-area 12CO J = 3-2 emission mapping of three nearby field galaxies, NGC 628, NGC 3521, and NGC 3627, completed at the James Clerk Maxwell Telescope as part of the Nearby Galaxies Legacy Survey. ...
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 ...
Heracles: The HERA CO Line Extragalactic Survey
(2009)
We present the Heterodyne Receiver Array CO Line Extragalactic Survey, an atlas of CO emission from 18 nearby galaxies that are also part of The H I Nearby Galaxy Survey and the Spitzer Infrared Nearby Galaxies Survey. We ...
