On the excess of power in high resolution CMB experiments
J. M. Diego, P. Vielva, E. Martinez-Gonalez +1
We revisit the possibility that an excess in the CMB power spectrum at small angular scales (CBI, ACBAR) can be due to galaxy clusters (or compact sources in general). We perform a…
Cosmology with Galaxy Clusters through the Sunyaev-Zel'dovich effect
J. M. Diego
Future Sunyaev-Zel'dovich effect (SZE) surveys will detect thousands of clusters, many of them at high redshift. We show how the SZE number counts as a function of flux can be used…
Redshift of Galaxy Clusters from the Sunyaev-Zel'dovich effect
J. M Diego, J. Mohr, J. Silk +1
We develop a new method for estimating the redshift of galaxy clusters through resolved images of the Sunyaev-Zel'dovich effect (SZE). Our method is based on morphological observab…
Cosmology with GTC. A combined mm-optical galaxy cluster survey
J. M. Diego, E. Martinez-Gonzalez, J. L. Sanz +2
The CMB Planck satellite (ESA) will provide a catalogue of nearly 30000 galaxy clusters (Sunyaev-Zel'dovich effect) between redshift 0 and approx. 2-3 (depending on the cosmologica…
A joint fit to the cosmological Model and the T-M and L_x-T relations using cluster data
J. M. Diego, E. Martinez-Gonzalez, J. L. Sanz +3
In this work we show how well can the cosmological parameters be constrained using galaxy cluster data. We also show how in the process of fitting the model which attempts to descr…
Constraints on Cluster Properties Using X-ray and Optical Data
J. M. Diego, E. Martinez-Gonzalez, J. L. Sanz +2
In this work we show that combining different cluster data sets is a powerful tool to constrain both, the cosmology and cluster properties. We assume a model with 9 parameters and…
