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…
