A multi-beam HI survey of the Virgo Cluster - two isolated HI clouds ?
J. Davies, R. Minchin, S. Sabatini +11
We have carried out a fully sampled large area () 21cm \HI line survey of part of the Virgo cluster using the Jodrell Bank multi-beam instrument. The su…
Is there a common origin for the WMAP low multipole and for the ellipticity in BOOMERanG CMB maps?
V. G. Gurzadyan, P. A. R. Ade, P. de Bernardis +19
We have measured the ellipticity of several degree scale anisotropies in the BOOMERanG maps of the Cosmic Microwave Background (CMB) at 150 GHz. The average ellipticity is around 2…
Detailed Studies of Cloud Cores: Probing the Initial Conditions for Protostellar Collapse
Philippe Andre, Arnaud Belloche, Patrick Hennebelle +1
Improving our understanding of the earliest stages of star formation is crucial to gain insight into the origin of stellar masses, multiple systems, and protoplanetary disks. We di…
Modification of Dust Grain Structure by Sputtering
M. D. Gray, M. G. Edmunds
We have applied the SRIM computer code to study the sputtering of some likely astrophysical grain materials, and we have shown that selective embedding of metallic projectiles offe…
The Canada-UK Deep Submillimetre Survey VIII: Source Identifications in the 3-hour field
Dave Clements, Steve Eales, Kris Wojciechowski +10
We present optical, near-infrared and radio observations of the 3-hour field of the Canada-UK Deep Submillimetre Survey. Of the 27 submillimetre sources in the field, nine have sec…
A Sample of Field Ellipticals
Rodney M. Smith, Vicent J. Martinez, Matthew J. Graham
Using well-defined selection criteria applied to the LEDA galaxy catalogue we have constructed a sample of elliptical galaxies that can be taken to lie in the field. Such criteria…
The Subillimeter Properties of Extremely Red Objects in the CUDSS Fields
Tracy Webb, Mark Brodwin, Steve Eales +1
We discuss the submillimeter properties of Extremely Red Objects (EROs) in the two Canada-UK Deep Submillimeter Survey (CUDSS) Fields. We measure the mean submillimeter flux of the…
Semi-analytical homologous solutions of the gravo-magnetic contraction
P. Hennebelle
We propose an extension of the semi-analytical solutions derived by Lin et al. (1965) describing the two-dimensional homologous collapse of a self-gravitating rotating cloud having…
Protostellar collapse induced by compression. II: rotation and fragmentation
P. Hennebelle, A. Whitworth, S. Cha +1
We investigate numerically and semi-analytically the collapse of low-mass, rotating prestellar cores. Initially, the cores are in approximate equilibrium with low rotation (the ini…
CDM in LSB Galaxies: Toward the Optimal Halo Profile
W. J. G. de Blok
Low Surface Brightness (LSB) galaxies are dominated by dark matter. High-resolution rotation curves suggest that their total mass-density distributions are dominated by constant de…
Dust obscuration studies along quasar sight lines using simulated galaxies
D. K. Churches, A. H. Nelson, M. G. Edmunds
We use the results of a set of three-dimensional SPH-Treecode simulations which model the formation and early evolution of disk galaxies, including the generation of heavy elements…
The dynamical evolution of fractal star clusters: the survival of substructure
Simon P. Goodwin, A. P. Whitworth
We simulate the dynamics of fractal star clusters, in order to investigate the evolution of substructure in recently formed clusters. The velocity dispersion is found to be the key…
Simulating star formation in molecular cloud cores I. The influence of low levels of turbulence on fragmentation and multiplicity
Simon P Goodwin, A P Whitworth, D. Ward-Thompson
We present the results of an ensemble of simulations of the collapse and fragmentation of dense star-forming cores. We show that even with very low levels of turbulence the outcome…
Satellites of Isolated Elliptical Galaxies
Rodney M. Smith, Vicent J. Martinez
Using well-defined selection criteria applied to the LEDA galaxy catalogue we have derived a sample of elliptical galaxies that can be classified as isolated. From this we have inv…
MAXIMA: A Balloon-Borne Cosmic Microwave Background Anisotropy Experiment
B. Rabii, C. D. Winant, M. E. Abroe +20
We describe the Millimeter wave Anisotropy eXperiment IMaging Array (MAXIMA), a balloon-borne experiment designed to measure the temperature anisotropy of the Cosmic Microwave Back…
The Canada-UK Deep Submillimeter Survey VII: Optical and near-infrared identifications for the 14h field
Tracy Webb, Simon Lilly, David Clements +5
We present the multi-wavelength identifications for 23 sources in the Canada-UK Deep Submillimeter Survey (CUDSS) 14h field. The identifications have been selected on the basis of…
HIDEEP - An extragalactic blind survey for very low column-density neutral hydrogen
R. F. Minchin, M. J. Disney, P. J. Boyce +13
We have carried out an extremely long integration-time (9000 s/beam) 21-cm blind survey of 60 square degrees in Centaurus using the Parkes multibeam system. We find that the noise…
MAXIPOL: A Balloon-borne Experiment for Measuring the Polarization Anisotropy of the Cosmic Microwave Background Radiation
B. R. Johnson, M. E. Abroe, P. Ade +17
We discuss MAXIPOL, a bolometric balloon-borne experiment designed to measure the E-mode polarization anisotropy of the cosmic microwave background radiation (CMB) on angular scale…
Why do starless cores appear more flattened than protostellar cores?
Simon P Goodwin, D. Ward-Thompson, A. P. Whitworth
We evaluate the intrinsic three dimensional shapes of molecular cores, by analysing their projected shapes. We use the recent catalogue of molecular line observations of Jijina et…
The Planck High Frequency Instrument, a 3rd generation CMB experiment, and a full sky submillimeter survey
J. M. Lamarre, J. L. Puget, F. Bouchet +23
The High Frequency Instrument (HFI) of Planck is the most sensitive CMB experiment ever planned. Statistical fluctuations (photon noise) of the CMB itself will be the major limitat…
The Origin of Cosmic Dust
Loretta Dunne, Stephen Eales, Rob Ivison +2
Large amounts of dust have recently been discovered in high-z galaxies and QSOs. The stellar winds produced by AGB stars are thought to be the main source of dust in galaxies, but…
Monte Carlo Radiative Transfer in Embedded Prestellar Cores
D. Stamatellos, A. P. Whitworth
We implement a Monte Carlo radiative transfer method, that uses a large number of monochromatic luminosity packets to represent the radiation transported through a system. These pa…
