The Gamow Explorer: A gamma-ray burst observatory to study the high redshift universe and enable multi-messenger astrophysics

N. E. White, F. E. Bauer, W. Baumgartner +63

The Gamow Explorer will use Gamma Ray Bursts (GRBs) to: 1) probe the high redshift universe (z > 6) when the first stars were born, galaxies formed and Hydrogen was reionized; and…

A Deep Search with HST for Late Time Supernova Signatures in the Hosts of XRF 011030 and XRF 020427

Andrew Levan, Sandeep Patel, Chryssa Kouveliotou +16

X-ray Flashes (XRFs) are, like Gamma-Ray Bursts (GRBs), thought to signal the collapse of massive stars in distant galaxies. Many models posit that the isotropic equivalent energie…

New Constraints on , , and w from an Independent Set of Eleven High-Redshift Supernovae Observed with HST

R. A. Knop, G. Aldering, R. Amanullah +45

We report measurements of , , and w from eleven supernovae at z=0.36-0.86 with high-quality lightcurves measured using WFPC-2 on the HST. This is an independent set of hi…

GRB 020813: polarization in the case of a smooth optical decay

J. Gorosabel, E. Rol, S. Covino +35

We present the results of a VLT polarimetric monitoring campaign of the GRB 020813 optical afterglow carried out in three nights, from 0.88 to 4.20 days after the gamma-ray event.…

Optical and NIR Observations of the Afterglow of GRB 020813

S. Covino, D. Malesani, F. Tavecchio +28

We present optical and near-infrared (NIR) photometry of the bright afterglow of GRB 020813. Our data span from 3 hours to 4 days after the GRB event. A rather sharp achromatic bre…

Overview of the SuperNova/Acceleration Probe (SNAP)

G. Aldering, SNAP collaboration

The SuperNova / Acceleration Probe (SNAP) is a space-based experiment to measure the expansion history of the Universe and study both its dark energy and the dark matter. The exper…
