Gamma-Ray Burst Luminosity Functions Based On a Newly Discovered Correlation Between Peak Spectral Energy and V/V_max

Maarten Schmidt

We have discovered a correlation between the observed peak spectral energy E_pk,obs and the average Euclidean value of V/V_max of gamma-ray bursts (GRBs). We present the evidence f…

Are Durations of Weak Gamma-Ray Bursts Reliable?

Maarten Schmidt

Simulations in the GUSBAD Catalog of gamma-ray bursts suggest that the apparent duration of a burst decreases as its amplitude is decreased. We see no evidence for this effect in t…

Luminosity-dependent evolution of soft X-ray selected AGN: New Chandra and XMM-Newton surveys

G. Hasinger, T. Miyaji, M. Schmidt

We present new results on the cosmological evolution of unabsorbed (type-1) active galactic nuclei (AGN) selected in the soft (0.5-2 keV) X-ray band. From a variety of ROSAT, XMM-N…

The SDSS View of the Palomar-Green Bright Quasar Survey

Sebastian Jester, Donald P. Schneider, Gordon T. Richards +12

We investigate the extent to which the Palomar-Green (PG) Bright Quasar Survey (BQS) is complete and representative of the general quasar population by comparing with imaging and s…

The GUSBAD Catalog of Gamma-Ray Bursts

Maarten Schmidt

The GUSBAD catalog of gamma-ray bursts (GRBs) is based on archival BATSE DISCLA data covering the full 9.1 years of the Compton Gamma Ray Observatory mission. The catalog contains…

Luminosities and Space Densities of Short Gamma-Ray Bursts

Maarten Schmidt

Using the Euclidean value of <V/Vmax> as a cosmological distance indicator, we derive the isotropic-equivalent characteristic peak luminosity of gamma-ray bursts both longer and sh…
