Estimates of Cosmological Parameters Using the CMB Angular Power Spectrum of ACBAR
J. H. Goldstein, P. A. R. Ade, J. J. Bock +14
We report an investigation of cosmological parameters based on the measurements of anisotropy in the cosmic microwave background radiation (CMB) made by ACBAR. We use the ACBAR dat…
High Resolution Observations of the CMB Power Spectrum with ACBAR
C. L. Kuo, P. A. R. Ade, J. J. Bock +11
We report the first measurements of anisotropy in the cosmic microwave background (CMB) radiation with the Arcminute Cosmology Bolometer Array Receiver (ACBAR). The instrument was…
Improved Measurement of the Angular Power Spectrum of Temperature Anisotropy in the CMB from Two New Analyses of BOOMERANG Observations
J. E. Ruhl, P. A. R. Ade, J. J. Bock +27
We report the most complete analysis to date of observations of the Cosmic Microwave Background (CMB) obtained during the 1998 flight of BOOMERANG. We use two quite different metho…
Simulating Observations of Dark Matter Dominated Galaxies: Towards the Optimal Halo Profile
W. J. G. de Blok, A. Bosma, S. S. McGaugh
Low Surface Brightness (LSB) galaxies are dominated by dark matter, and their rotation curves thus reflect their dark matter distribution. Recent high-resolution rotation curves su…
Where has all the neutral hydrogen gone?
M. J. Disney, R. F. Minchin
Our extremely deep survey for extragalactic HI (HIDEEP) finds no intergalactic gas clouds, and no galaxies with HI at inferred global column-densities below 10^20 cm^-2 when we cou…
Stability of the Submillimeter Brightness of the Atmosphere Above Mauna Kea, Chajnantor and the South Pole
J. B. Peterson, S. J. E. Radford, P. A. R. Ade +4
The summit of Mauna Kea in Hawaii, the area near Cerro Chajnantor in Chile, and the South Pole are sites of large millimeter or submillimeter wavelength telescopes. We have placed…
A Limit on the Cosmological Mass Density and Power Spectrum from the Rotation Curves of Low Surface Brightness Galaxies
S. McGaugh, M. Barker, E. de Blok
The concentrations of the cuspy dark matter halos predicted by simulations of cold dark matter are related to the cosmology in which the halos form. Observational constraints on ha…
Self-similar condensation of rotating magnetized self-gravitating isothermal filaments
P. Hennebelle
Ordinary differential equations describing the self-similar collapse of a rotating, magnetized, self-gravitating and isothermal filament are derived. Explicit homologous solutions…
The SCUBA Local Universe Galaxy Survey
L. Dunne, S. A. Eales
The SCUBA local universe galaxy survey is the first systematic survey of the local universe at submillimetre wavelengths. We have observed ~200 galaxies from the IRAS bright galaxy…
Molecular gas freeze-out in the pre-stellar core L1689B
M. P. Redman, J. M. C. Rawlings, D. J. Nutter +2
C17O (J=2-1) observations have been carried out towards the pre-stellar core L1689B. By comparing the relative strengths of the hyperfine components of this line, the emission is s…
The Large Scale Distribution of Neutral Hydrogen in the Fornax Region
Meryl Waugh, M. J. Drinkwater, R. L. Webster +22
Using HIPASS data, we have searched for HI in a ~25x25 sq.deg. region centred on the Fornax cluster. Within a velocity search range of 300 - 3700 km/s and a lower flux limit of ~40…
Cosmological constraints from Archeops
A. Benoit, P. Ade, A. Amblard +65
We analyze the cosmological constraints that Archeops places on adiabatic cold dark matter models with passive power-law initial fluctuations. Because its angular power spectrum ha…
The Cosmic Microwave Background Anisotropy Power Spectrum measured by Archeops
A. Benoit, P. Ade, A. Amblard +65
We present a determination by the Archeops experiment of the angular power spectrum of the cosmic microwave background anisotropy in 16 bins over the multipole range l=15-350. Arch…
A census of metals at high and low redshifts and the connection between submillimetre sources and spheroid formation
L. Dunne, S. A. Eales, M. G. Edmunds
Deep surveys in many wavebands have shown that the rate at which stars were forming was at least a factor of 10 higher at z > 1 than today. Heavy elements (metals) are produced by…
Measuring the Geometry and Topology of Large Scale Structure using SURFGEN: Methodology and Preliminary Results
Jatush V. Sheth, Varun Sahni, Sergei F. Shandarin +1
We present a new ansatz which can successfully be used to determine the morphological properties of the supercluster-void network. The ansatz is based on a surface modelling scheme…

V. G. Gurzadyan, P. A. R. Ade, P. de Bernardis +20
The properties of the Cosmic Microwave Background (CMB) maps carry valuable cosmological information. Here we report the results of the analysis hot and cold CMB anisotropy spots i…
