The Spectral Energy Distribution of Fermi bright blazars
A. A. Abdo, M. Ackermann, M. Ajello +107
(Abridged) We have conducted a detailed investigation of the broad-band spectral properties of the γ-ray selected blazars of the Fermi LAT Bright AGN Sample (LBAS). By combining ou…
Fermi Observations of GRB 090902B: A Distinct Spectral Component in the Prompt and Delayed Emission
GBM collaboration, LAT Collaboration, The Swift Team
We report on the observation of the bright, long gamma-ray burst, GRB 090902B, by the Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) instruments on-board the Fermi ob…
A multiwavelength study of Swift GRB 060111B constraining the origin of its prompt optical emission
G. Stratta, A. Pozanenko, J-L. Atteia +18
In this work, we present the results obtained from a multi-wavelength campaign, as well as from the public Swift/BAT, XRT, and UVOT data of GRB 060111B for which a bright optical e…
A glimpse of the end of the dark ages: the gamma-ray burst of 23 April 2009 at redshift 8.3
N. R. Tanvir, D. B. Fox, A. J. Levan +59
It is thought that the first generations of massive stars in the Universe were an important, and quite possibly dominant, source of the ultra-violet radiation that reionized the hy…
