Reaction-rates for Sm-146 production in supernovae
Correlations of the Nd-142/Nd-144 ratio with the Sm/Nd ratio in some meteorites have been previously explained by the alpha-decay of long-lived Sm-146. In order to account for these observations, a necessary production ...
The Spectral Evolution of High-Frequency Radio Outbursts in the Blazar PKS:0420-014
Multifrequency monitoring data between 375 and 22 GHz are used to investigate spectral evolution of radio outbursts in the blazar 0420-014. It is shown that, after subtraction of the underlying `quiescent' emission, the ...
Study of short-lived silver isotopes with a laser ion-source
A chemically selective laser ion source based on resonance ionization of atoms in a hot cavity has been applied for the study of short-lived silver isotopes at CERN/ISOLDE. Silver atoms were ionized by two resonant excitations ...
An H i/Optical Atlas of H II Galaxies and Their Companions
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 ...
High Resolution Studies of Molecular Hydrogen by Means of Near-Infrared Fabry-Perot Imaging
(Astronomical Society of the Pacific, 1995)
We present a study of the velocity profiles of the v=1-0 S(1) transition of molecular hydrogen (H2) towards the star forming region of OMC-1. A three dimensional data cube is presented which displays the spatial distribution ...
A model for the infrared continuum spectrum of NGC 1068
We present a model for the nuclear infrared (IR) continuum spectrum of the Seyfert galaxy NGC 1068. The torus emission is modelled in terms of the tapered disc models of Efstathiou & Rowan-Robinson, which give a good fit ...
Shell effects in neutron capture on Pb

Beta-decay studies of neutron-rich Sc, Ti, V, Cr

Near-IR spectropolarimetry and modeling of NGC 1068
We present new spectropolarimetric data for NGC 1068, including, for the first time, coverage in the near-IR. Using these, and other previously published data, we develop a scattering model for NGC 1068, using NGC 5548 for ...
