Early Ultraviolet, Optical and X-Ray Observations of the Type IIP SN 2005cs in M51 with Swift

Peter J. Brown, Luc Dessart, Stephen T. Holland +14

We report early photospheric-phase observations of the Type IIP Supernova (SN) 2005cs obtained by Swift's Ultraviolet-Optical and X-Ray Telescopes. Observations started within two…

Swift multi-wavelength observations of the bright flaring burst GRB051117A

M. R. Goad, K. L. Page, O. Godet +13

We report on the temporal and spectral characteristics of the early X-ray emission from the Gamma Ray Burst 051117A as observed by Swift. The superb quality of the early X-ray ligh…

Redshift Filtering by Swift Apparent X-ray Column Density

Dirk Grupe, John A. Nousek, Daniel E. vanden Berk +5

We remark on the utility of an observational relation between the absorption column density in excess of the Galactic absorption column density, $ΔN_{\rm H} = N_{\rm H, fit} - N_{\…

SWIFT observations of TeV BL Lac objects

A. Tramacere, P. Giommi, E. Massaro +10

Context: We present the results of a set of observations of nine TeV detected BL Lac objects performed by the XRT and UVOT detectors on board the Swift satellite between March and…

Swift and XMM-Newton Observations of the Extraordinary GRB 060729: An afterglow with a more than 100 days X-ray light curve

Dirk Grupe, Caryl Gronwall, Xiang-Yu Wang +8

We report the results of the Swift and XMM observations of the Swift-discovered long Gamma-Ray Burst GRB 060729 (=115s). The afterglow of this burst was exceptionally brigh…

GRB Radiative Efficiencies Derived from the Swift Data: GRBs vs. XRFs, Long vs. Short

Bing Zhang, Enwei Liang, Kim L. Page +17

We systematically analyze the prompt emission and the early afterglow data of a sample of 31 GRBs detected by {\em Swift} before September 2005, and estimate the GRB radiative effi…
