Prolonged activity of the central engine of Gamma Ray Bursts

G. Ghisellini, M. Nardini, G. Ghirlanda

We call "prompt" emission of Gamma Ray Bursts (GRBs) the erratic and violent phase of hard X-ray and soft gamma-ray emission, usually lasting for tens of seconds in long GRBs. Howe…

The Chandra COSMOS Survey, I: Overview and Point Source Catalog

Martin Elvis, Francesca Civano, Cristian Vignali +40

The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8 Ms, Chandra} program that has imaged the central 0.5 sq.deg of the COSMOS field (centered at 10h, +02deg) with an effective exp…

Stellar and total baryon mass fractions in groups and clusters since redshift 1

S. Giodini, D. Pierini, A. Finoguenov +24

We investigate if the discrepancy between estimates of the total baryon mass fraction obtained from observations of the cosmic microwave background (CMB) and of galaxy groups/clust…

X-ray Cluster Cosmology

A. Vikhlinin, S. Murray, R. Gilli +18

Sensitive, wide-area X-ray surveys which would be possible with the WFXT will detect huge samples of virialized objects spanning the mass range from sub-groups to the most massive…

In Situ Probes of the First Galaxies and Reionization: Gamma-ray Bursts

Matthew McQuinn, Joshua S. Bloom, Jonathan Grindlay +20

The first structures in the Universe formed at z>7, at higher redshift than all currently known galaxies. Since GRBs are brighter than other cosmological sources at high redshift a…

Blazars in hard X-rays

Gabriele Ghisellini

Although blazars are thought to emit most of their luminosity in the gamma-ray band, there are subclasses of them very prominent in hard X-rays. These are the best candidates to be…
