Do Submillimeter Galaxies Trace Megaparsec Large-scale Structures? -- An Overdensity Analysis of 449 Submillimeter Galaxies in COSMOS

Canze Deng, Daizhong Liu, Helmut Dannerbauer +19

We present an environmental analysis and overdensity catalog for a large sample of submillimeter galaxies (SMGs) in the COSMOS field in order to understand whether SMGs are signpos…

AGN torus emission for a homogeneous sample of bright FSRQs

Gianluca Castignani, Gianfranco De Zotti

We have selected a complete sample of 80 flat-spectrum radio quasars (FSRQs) from the WMAP 7-yr catalog within the SDSS area, all with measured redshift, and have inspected their S…

Cluster candidates around low power radio-galaxies at z~1-2 in COSMOS

Gianluca Castignani, Marco Chiaberge, Annalisa Celotti +2

We search for high redshift (1-2) galaxy clusters using low luminosity radio galaxies (FR~I) as beacons and our newly developed Poisson Probability Method (PPM) based on pho…

A new method to search for high redshift clusters using photometric redshifts

Gianluca Castignani, Marco Chiaberge, Annalisa Celotti +1

We describe a new method (Poisson Probability Method, PPM) to search for high redshift galaxy clusters and groups by using photometric redshift information and galaxy number counts…

Time delays between Fermi LAT and GBM light curves of GRBs

Gianluca Castignani, Dafne Guetta, Elena Pian +3

Most Gamma-Ray Bursts (GRBs) detected by the Fermi Gamma-ray Space Telescope exhibit a delay of up to about 10 seconds between the trigger time of the hard X-ray signal as measured…

Black-hole mass estimates for a homogeneous sample of bright flat-spectrum radio quasars

Gianluca Castignani, Francesco Haardt, Andrea Lapi +3

We have selected a complete sample of flat-spectrum radio quasars (FSRQs) from the WMAP 7-yr catalog within the SDSS area, all with measured redshift, and have compared the black h…
