Omega from the COBE-DMR anisotropy maps
L. Cayon, E. Martinez-Gonzalez, J. L. Sanz +2
We have made a likelihood statistical analysis of the angular correlations in the {\it COBE}-DMR two-year sky maps by Monte Carlo simulation of the temperature fluctuations. We ass…
High redshift AGNs from the 1Jy catalogue and the magnification bias
N. Benitez, E. Martinez-Gonzalez
We have found a statistically significant (99.1 \%) excess of red () galaxies with photographic magnitudes , taken from the APM Sky Catalogue around $z \sim…
INTERMEDIATE RESOLUTION SPECTROSCOPY OF THE RADIO GALAXY B2 0902+34 AT
J. M. Martin-Mirones, E. Martinez-Gonzalez, J. I. Gonzalez-Serrano +1
We have carried out spectroscopic observations of the high redshift () radio galaxy 0902+34 at intermediate resolution with the William Herschel Telescope. The dynami…
Genus and spot density in the COBE DMR first year anisotropy maps
S. Torres, L. Cayon, E. Martinez-Gonzalez +1
A statistical analysis of texture on the {\it COBE}-DMR first year sky maps based on the genus and spot number is presented. A generalized statistic is defined in terms of ``…
