The First Swift Ultra-Violet/Optical Telescope GRB Afterglow Catalog
P. W. A. Roming, T. S. Koch, S. R. Oates +21
We present the first Swift Ultra-Violet/Optical Telescope (UVOT) gamma-ray burst (GRB) afterglow catalog. The catalog contains data from over 64,000 independent UVOT image observat…
Multiwavelength Observations of the Powerful Gamma-ray Quasar PKS 1510-089: Clues on the Jet Composition
J. Kataoka, G. Madejski, M. Sikora +16
We present the results from a multiwavelength campaign of the powerful Gamma-ray quasar PKS 1510-089. This campaign commenced with a deep Suzaku observation lasting three days for…
Photometric Calibration of the Swift Ultraviolet/Optical Telescope
T. S. Poole, A. A. Breeveld, M. J. Page +28
We present the photometric calibration of the Swift UltraViolet/Optical Telescope (UVOT) which includes: optimum photometric and background apertures, effective area curves, colour…
ROXA J081009.9+384757.0: a erg/s blazar with hard X-ray synchrotron peak or a new type of radio loud AGN?
P. Giommi, E. Massaro, P. Padovani +10
We report the discovery of ROXA J081009.9+384757.0 = SDSS J081009.9+384757.0, a z=3.95 blazar with a highly unusual Spectral Energy Distribution (SED). This object was first notice…
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…
