mm VLBA Observations of SiO masers: probing the close stellar environment of the PPN OH231.8+4.2
J. F. Desmurs, C. Sanchez Contreras, V. Bujarrabal +2
We present milliarsecond-resolution maps of the SiO maser emission v=1 J=2-1 (3 mm) in the bipolar post-AGB nebula OH231.8+4.2, and compare them with our previous observations of t…
Small-scale anisotropy and intermittency in high and low-latitude solar wind
A. Bigazzi, L. Biferale, S. M. A. Gama +1
We analyze low and high--latitude fast solar wind data from the Ulysses spacecraft from 1992 to 1994 using a a systematic method to analyse the anisotropic content of the magnetic…
Accurate determination of the mass distribution in spiral galaxies III. Fabry-Perot imaging spectroscopy of 6 spiral galaxies
S. Blais-Ouellette, P. Amram, C. Carignan +1
High resolution Fabry-Perot data of six spiral galaxies are presented. Those data extend the previous sample of spiral galaxies studied with high resolution 3D spectroscopy to earl…
The Lens Redshift and Group Environment for HE 0435-1223
Nicholas D. Morgan, Christopher S. Kochanek, Olga Pevunova +1
The redshift of the galaxy lensing HE 0435-1223 is 0.4546 +/- 0.0002, based on observations obtained with the Low Dispersion Survey Spectrograph 2 (LDSS2) on the Magellan Consortiu…
Infrared Properties of Cataclysmic Variables in the 2MASS All Sky Data Release
D. W. Hoard, C. S. Brinkworth, S. Wachter
We present results from our analysis of the near-infrared (J, H, and Ks) photometry for all cataclysmic variables from the catalog of Downes et al. (2001) that are detected in the…
The radio source population at high frequency: follow-up of the 15-GHz 9C survey
R. C. Bolton, G. Cotter, G. G. Pooley +6
We have carried out extensive radio and optical follow-up of 176 sources from the 15 GHz 9th Cambridge survey. Optical identifications have been found for 155 of the radio sources;…
Self-Consistent Theory of Halo Mergers
Andrew J. Benson, Marc Kamionkowski, Steven H. Hassani
The rate of merging of dark-matter halos is an absolutely essential ingredient for studies of both structure and galaxy formation. Remarkably, however, our quantitative understandi…
ImpZ: a new photometric redshift code for galaxies and quasars
T. S. R Babbedge, M. Rowan-Robinson, E. Gonzalez-Solares +7
We present a combined galaxy-quasar approach to template-fitting photometric redshift techniques and show the method to be a powerful one. The code (ImpZ) is presented, developed a…
The substellar population of the young cluster lambda Orionis
David Barrado y Navascues, J. R. Stauffer, J. Bouvier +2
By collecting optical and infrared photometry and low resolution spectroscopy, we have identified a large number of low mass stars and brown dwarf candidates belonging to the young…
Warm dust and aromatic bands as quantitative probes of star-formation activity
N. M. Forster Schreiber, H. Roussel, M. Sauvage +1
We combine samples of spiral galaxies and starburst systems observed with ISOCAM to investigate the reliability of mid-infrared (MIR) dust emission as a quantitative tracer of star…
The 2D Continuum Radiative Transfer Problem: Benchmark Results for Disk Configurations
I. Pascucci, S. Wolf, J. Steinacker +5
We present benchmark problems and solutions for the continuum radiative transfer (RT) in a 2D disk configuration. The reliability of three Monte-Carlo and two grid-based codes is t…
BVRIJK light curves and radial velocity curves for selected Magellanic Cloud Cepheids
Jesper Storm, Bruce W. Carney, Wolfgang P. Gieren +4
We present high precision and well sampled BVRIJK light curves and radial velocity curves for a sample of five Cepheids in the SMC. In addition we present radial velocity curves fo…
