The CFHTLS Real Time Analysis System "Optically Selected GRB Afterglows"

We combined the Fermi /GBM and LAT data in joint spectral fits to characterize the time evolution of its spectrum from keV to GeV energies, using a Band+CUTBPL spectral model in view

We present data and initial results from X-Shooter emission- line spectroscopy of star-forming galaxies selected through long GRBs in a redshift range 0.1 < z < 3.6.. In total,

Also overplotted on the first epoch spectrum is a power-law (with slope set by a fit to the X-ray afterglow and assuming a Δβ = 0.5 cooling break between the X-rays and the

The analysis can be divided into two main parts: the study of the abundance pattern in the host galaxy measured by the afterglow absorption lines, and the study of the ionised

The pres- ence of strong stellar absorption features coupled with a weak [O ii ] emission line in the X-Shooter spectrum suggest that the host galaxy candidate is a low-mass member

4.5. We prefer to adopt a different approach while fitting.. GRB 120327A absorption features detected in the X-shooter NIR arm. Solid, red lines represent the best-fit model to the

While the detection of orphan afterglows was initially pro- posed as a way to constrain GRB beaming (Rhoads 1997), more recent work has shown that the number of visible after-

Once again, the process selects approximatively 0.05% of luminosity variable objects down to magnitude r’ = 22, and 11 objects which were classified as matched in the
