Guilt, Agency, Listening and 32-bit – a composer’s need to capture the sound of Covid
(2021-06-01)As a composer and sound designer, academic and researcher, listener, cyclist, home-schooler and dad, my working patterns and life-style have changed enormously over the past year. Having taken for granted many aspects of ... -
Gyrospun antimicrobial nanoparticle loaded fibrous polymeric filters
(2017-05-01)A one step approach to prepare hybrid nanoparticle embedded polymer fibres using pressurised gyration is presented. Two types of novel antimicrobial nanoparticles and poly (methylmethacrylate) polymer were used in this ... -
H 2O and OH Masers as Probes of the Obscuring Torus in NGC 1068
(1996)We report the discovery of OH masers and positionally resolved H_2_O maser emission in the nucleus of NGC 1068. The brightest H_2_O masers are associated with the radio continuum component that is probably the location of ... -
The H alpha galaxy survey. I. The galaxy sample, H alpha narrow-band observations and star formation parameters for 334 galaxies
(2004)We discuss the selection and observations of a large sample of nearby galaxies, which we are using to quantify the star formation activity in the local Universe. The sample consists of 334 galaxies across all Hubble types ... -
H alpha spectropolarimetry of the Herbig Ae star AB Aurigae
(2000)We present spectropolarimetric observations, obtained at Hα, of the Herbig Ae star AB Aurigae. Changes in linear polarization across the Hα line probe structure in the immediate circumstellar environment of the central ... -
An H I absorption line survey of Messier 31
(1988-08-01)The 21-cm absorption through the disk of M31 has been observed, using the VLA to study the cool atomic phase of the interstellar medium in this nearby spiral galaxy. It is found that the abundance of diffuse clouds with ... -
An H I absorption survey of M31 and M33 - The mixture of warm and cool phases in the interstellar media of spiral galaxies
(1993)The VLA in A-array is used to survey the nearby spiral galaxies M31 and M33 in the 21-cm line in order to measure absorption by the H I toward background continuum sources. Spectral line cubes with rms noise less than 1.2 ... -
H I and CO Emission in Blue Compact Dwarfs: Haro 2 and Haro 4/26
(Astronomical Society of the Pacific, 2002)We present VLA HI imaging of two actively star-forming dwarf galaxies, Haro 2 and Haro 4, and of the spiral galaxy NGC 3510 (Haro 26), some 22' SW of Haro 4 (8.5kpc). We also present a map of the CO(1-0) distribution 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 ... -
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 ... -
