In-flight calibration of the SWIFT XRT effective area
P. Romano,Giancarlo Cusumano,Sergio Campana,V. Mangano,Alberto Moretti,A. F. Abbey,Lorella Angelini,A. P. Beardmore,David N. Burrows,M. Capalbi,Guido Chincarini,Oberto Citterio,P. Giommi,M. R. Goad,Olivier Godet,Gisela Hartner,Joanne E. Hill,J. A. Kennea,V. LaParola,Teresa Mineo,D. C. Morris,J. A. Nousek,J. P. Osborne,K. L. Page,C. Pagani,C. Pagani,M. Perri,G. Tagliaferri,F. Tamburelli,Alan A. Wells +29 more
TL;DR: In this article, the authors report the initial results of the analysis of the Swift X-ray Telescope effective area as measured both on-axis and off-axis during the in-flight calibration phase using the laboratory results and ray-tracing simulations as a starting point.

GRB 050410 and GRB 050412: are they really dark gamma-ray bursts?
Teresa Mineo,V. Mangano,Stefano Covino,Gaspare Cusumano,V. La Parola,Eleonora Troja,P. W. A. Roming,David N. Burrows,Sergio Campana,M. Capalbi,G. Chincarini,N. Gehrels,P. Giommi,Joanne E. Hill,Joanne E. Hill,F. E. Marshall,A. Moretti,P. T. O'Brien,M. J. Page,M. Perri,P. Romano,B. Sbarufatti,G. Sato,Gianpiero Tagliaferri +23 more
TL;DR: The GRB-050410 afterglow light curve reveals the expected characteristics of the third component of the canonical Swift light curve and a complex phenomenology was detected in the GRB 050412 because of the presence of the very early break.

An X-ray Polarimeter for Constellation-X
Keith Jahoda,K. Black,P. Deines-Jones,Joanne E. Hill,T. R. Kallman,Tod E. Strohmayer,J. H. Swank +6 more
TL;DR: Polarimetry remains a largely unexploited technique in observational X-ray astronomy which could provide insight in the study of the strong gravity and magnetic fields at the core of the Constellation-X observational program as discussed by the authors.
