An on-going multi-wavelength survey of Ly-alpha emitters at redshifts z = 2 - 8
Kim K. Nilsson, Johan P. U. Fynbo, Palle Moller +1
In the last decade, the technique of finding Ly-alpha emitters through narrow-band imaging has become a promising method of detecting high redshift galaxies. Ly-alpha emitters have…
Photometry with FORS at the ESO VLT
W. Freudling, M. Romaniello, F. Patat +3
ESO's two FOcal Reducer and low dispersion Spectrographs (FORS) are the primary imaging cameras for the VLT. Since they are not direct-imaging cameras, the accuracy of photometry w…
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…
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…
Velocity-Metallicity Correlation for high-z DLA Galaxies: Evidence for a Mass-Metallicity Relation?
C. Ledoux, P. Petitjean, J. P. U. Fynbo +2
We used our database of VLT-UVES quasar spectra to build up a sample of 70 Damped Lyman-alpha (DLA) or strong sub-DLA systems with total neutral hydrogen column densities of log N(…
Physics of the GRB 030328 afterglow and its environment
E. Maiorano, N. Masetti, E. Palazzi +30
We report on the photometric, spectroscopic and polarimetric, monitoring of the optical afterglow of Gamma-Ray Burst (GRB) 030328 detected by HETE-2. Photometry, collected at 7 dif…
