Derivation of Distances with the Tully-Fisher Relation: The Antlia Cluster
N. Bonhomme, H. M. Courtois, R. B. Tully
The Tully-Fisher relation is a correlation between the luminosity and the HI 21cm line width in spiral galaxies (LLW relation). It is used to derive galaxy distances in the interva…
Our Peculiar Motion Away from the Local Void
R. Brent Tully, Edward J. Shaya, Igor D. Karachentsev +4
The peculiar velocity of the Local Group of galaxies manifested in the Cosmic Microwave Background dipole is found to decompose into three dominant components. The three components…
MoLUSC: A MOck Local Universe Survey Constructor
T. Sousbie, H. Courtois, G. Bryan +1
This paper presents MoLUSC, a new method for generating mock galaxy catalogs from a large scale ( Mpc) dark matter simulation, that requires only modest CPU tim…
The Supernova Legacy Survey: Measurement of Omega_M, Omega_Lambda and w from the First Year Data Set
P. Astier, J. Guy, N. Regnault +39
We present distance measurements to 71 high redshift type Ia supernovae discovered during the first year of the 5-year Supernova Legacy Survey (SNLS). These events were detected an…
The abundance of Lyman-(α) emitters in hierarchical models
Morgan Le Delliou, Cedric Lacey, Carlton M. Baugh +5
We present predictions for the abundance of Ly- emitters in hierarchical structure formation models. We use the {\tt GALFORM} semi-analytical model to explore the impact on the…
The LEDA galaxy distribution: I. Maps of the Local Universe
Helene Courtois, Georges Paturel, Thierry Sousbie +1
In order to investigate the properties of large-scale structures of galaxies in the universe, we present an analysis of their spatial distribution at z0.033. We used the LEDA ex…
