The SZ effect as a cosmological discriminator
J. M. Diego, E. Martinez-Gonzalez, J. L. Sanz +2
We show how future measurements of the SZ effect (SZE) can be used to constrain the cosmological parameters. We combine the SZ information expected from the Planck full-sky survey,…
Quasar-galaxy associations revisited
N. Benitez, J. L. Sanz, E. Martinez-Gonzalez
Gravitational lensing predicts an enhancement of the density of bright, distant QSOs around foreground galaxies. We measure this QSO-galaxy correlation w_qg for two complete sample…
Segregated Optical-NIR colour distributions of MDS galaxies
I. Ferreras, L. Cayon, E. Martinez-Gonzalez +2
We present a K survey of 29 fields covering approximately 90 arcmin^2 from the Medium Deep Survey (MDS) catalogue down to a completeness magnitude of K=18.0 (limiting magnitude K=1…
Are optically-selected QSO catalogs biased ?
I. Ferreras, N. Benitez, E. Martinez-Gonzalez
A thorough study of QSO-galaxy correlations has been done on a region close to the North Galactic Pole using a complete subsample of the optically selected CFHT/MMT QSO survey and…
Weak lensing correlations in open and flat universes
J. L. Sanz, E. Martinez-Gonzalez, N. Benitez
Correlations between the magnification or polarization of background sources, induced by gravitational lensing due to the large-scale structure, and the positions of foreground gal…
R-Band Imaging of Fields Around 1<z<2 Radiogalaxies
N. Benitez, E. Martinez-Gonzalez, J. I. Gonzalez-Serrano +1
We have taken deep -band images of fields around five radiogalaxies: 0956+47, 1217+36, 3C256, 3C324 and 3C294 with . 0956+47 is found to show a double nucleus. Our data…
