PublicationPeculiar Transverse Velocities of Galaxies from Quasar Microlensing. Tentative Estimate of the Peculiar Velocity Dispersion at z ~ 0.5
We propose to use the flux variability of lensed quasar images induced by gravitational microlensing to measure the transverse peculiar velocity of lens...

PublicationRelationships between cluster densities and other statistical quantities.
We present a procedure for obtaining the cluster densities in terms of the probability, P_n_(r), for a randomly placed sphere of radius r to contain n galaxies...

PublicationThe Herschel-PEP survey: evidence for downsizing in the hosts of dusty star-forming systems
By making use of Herschel PACS Evolutionary Probe observations of the COSMOS and Extended Groth Strip fields, we have estimated the dependence of the clustering...

PublicationThe structure models for galaxy clustering.
The models for galaxy clustering in which galaxies are identified with peaks on the mass density field smoothed on an appropriate scale are plagued by some...
