The Supernova Type Ia Rate Evolution with SNLS
J. D. Neill, M. Sullivan, D. Balam +36
We present a progress report on a project to derive the evolution of the volumetric supernova Type Ia rate from the Supernova Legacy Survey. Our preliminary estimate of the rate ev…
Supernova search at intermediate z. II. Host galaxy morphology
J. Mendez, P. Ruiz-Lapuente, G. Altavilla +6
We discuss the host galaxy morphology of the 8 SNe discovered as a part of the International Time Programme (ITP) project ``Omega and Lambda from Supernovae, and the Physics of Sup…
Supernova search at intermediate z. I. Spectroscopic analysis
G. Altavilla, P. Ruiz-Lapuente, A. Balastegui +7
We study 8 supernovae discovered as part of the International Time Programme (ITP) project ``Omega and Lambda from Supernovae and the Physics of Supernova Explosions'' at the Europ…
Sunyaev-Zel'dovich constraints from black hole-seeded proto-galaxies
N. Aghanim, C. Balland, J. Silk
Recent studies of galactic nuclei suggest that most galaxies are seeded by super-massive black holes which power the central nucleus. In this picture, the proto-galactic object is…
On the Uncertainty in X-Ray Cluster Mass Estimates
C. Balland, A. Blanchard
We study the uncertainty in galaxy cluster mass estimates derived from X-ray data assuming hydrostatic equilibrium (HE) for the intra cluster gas. Using a Monte-Carlo procedure we…
