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 ... -
H I Distribution in Blue Compact Dwarf Galaxies
(Astronomical Society of the Pacific, 2000)We present VLA HI observations and preliminary results for two dwarf galaxies, Haro 2 (Mrk 33) and Haro 4 (Mrk 36, which are currently experiencing a burst of star formation. We analyze the distribution and kinematics of ... -
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 ... -
H I Recycling: Formation of Tidal Dwarf Galaxies
(Astronomical Society of the Pacific, 2001)Galactic collisions trigger a number of phenomena, such as transportation inward of gas from distances of up to kiloparsecs from the center of a galaxy to the nuclear region, fueling a central starburst or nuclear activity. ... -
An H i/Optical Atlas of H II Galaxies and Their Companions
(1995)We have conducted a directed search for intergalactic H I clouds, using H II galaxies as pointers to fields on the sky likely to contain such clouds. This extends our previous survey (Taylor et al. 1993) by using the VLA ... -
H IIRegion Statistics in Barred and Non-Barred Galaxies
(1996)We present new high quality Ha continuum-subtracted images of the grand design galaxies NGC 157, NGC 3631, NGC 6764, and NGC 6951, two of them barred and two non-barred, and describe the statistical properties of the HII ... -

H-1 NMR study of the conformation and absolute stereochemistry of two spirocyclic NK-1 antagonists
(2005-08)The binding affinities at the human NK-1 receptor of two spirocyclic compounds were found to be similar despite being epimeric at a key stereocentre. This unexpected result prompted a thorough investigation of the solution ... -
H-ATLAS : PACS imaging for the Science Demonstration Phase
(2010)We describe the reduction of data taken with the PACS instrument on board the Herschel Space Observatory in the Science Demonstration Phase of the Herschel-ATLAS (H-ATLAS) survey, specifically data obtained for a 4 × 4 ... -
H-ATLAS/GAMA : Quantifying the morphological evolution of the galaxy population using cosmic calorimetry
(2015-10-01)Using results from the Herschel Astrophysical Terrahertz Large-Area Survey and the Galaxy and Mass Assembly project, we show that, for galaxy masses above approximately 1.0e8 solar masses, 51% of the stellar mass-density ... -
H-ATLAS/GAMA : The nature and characteristics of optically red galaxies detected at submillimetre wavelengths
(2016-02-21)We combine Herschel/SPIRE sub-millimeter (submm) observations with existing multi-wavelength data to investigate the characteristics of low redshift, optically red galaxies detected in submm bands. We select a sample of ... -
H2 Spectroscopy in the Photodissociation Region of M17 Northern Bar
(Astronomical Society of the Pacific, 1993)We present results of long slit spectroscopy, from 2.0 to 2.5 microns, of the photodissociation region in the northern bar of M17. The observations give us an insight into the physical conditions in the region and provide ... -
H2D+ in the High-Mass Star-Forming Region Cygnus X
(2012-06-01)H2D+ is a primary ion that dominates the gas-phase chemistry of cold dense gas. Therefore, it is hailed as a unique tool in probing the earliest, prestellar phase of star formation. Observationally, its abundance and ... -
H2O Southern Galactic Plane Survey (HOPS) : Paper III - Properties of Dense Molecular Gas across the Inner Milky Way
(2017-09-01)The H2O Southern Galactic Plane Survey (HOPS) has mapped 100 square degrees of the Galactic plane for water masers and thermal molecular line emission using the 22-m Mopra telescope. We describe the automated spectral-line ...
