Parameterization of the energy and rapidity distributions of secondary pions and kaons produced in energetic proton-proton collisions
Hylke B. J. Koers, Asaf Pe'er, Ralph A. M. J. Wijers
The possibility of proton acceleration to very high energies in astrophysical sources may have unique observational consequences. In particular, the decay of secondary mesons creat…
The LOFAR Transients Key Project
Rob Fender, Robert Braun, Ben Stappers +18
LOFAR, the Low Frequency Array, is a new radio telescope under construction in the Netherlands, designed to operate between 30 and 240 MHz. The Transients Key Project is one of the…
A very brief description of LOFAR - the Low Frequency Array
H. Falcke, M. P. van Haarlem, A. G. de Bruyn +28
LOFAR (Low Frequency Array) is an innovative radio telescope optimized for the frequency range 30-240 MHz. The telescope is realized as a phased aperture array without any moving p…
Constraints on an optical afterglow and on supernova light following the short burst GRB 050813
P. Ferrero, S. F. Sanchez, D. A. Kann +18
We report early follow-up observations of the error box of the short burst 050813 using the telescopes at Calar Alto and at Observatorio Sierra Nevada (OSN), followed by deep VLT/F…
No supernovae associated with two long-duration gamma ray bursts
Johan P. U. Fynbo, Darach Watson, Christina C. Thoene +28
It is now accepted that long duration gamma-ray bursts (GRBs) are produced during the collapse of a massive star. The standard "collapsar" model predicts that a broad-lined and lum…
Three intervening galaxy absorbers towards GRB060418: faint and dusty?
Sara L. Ellison, Paul Vreeswijk, Cedric Ledoux +8
We present an analysis of three strong, intervening Mg II absorption systems (z_abs = 0.603, 0.656, 1.107) towards the optical afterglow of gamma-ray burst (GRB) 060418. From high…
