A hint to the origin of the extended emission in LAT GRBs: the relation between LAT luminosity and prompt energetics
Lara Nava,Giacomo Vianello,Nicola Omodei,G. Ghisellini,G. Ghirlanda,Annalisa Celotti,F. Longo,R. Desiante +7 more
TL;DR: In this paper, the authors consider the 0.1-10 GeV rest frame light curves of 10 GRBs detected by LAT and with known redshift and derive limits on the distribution of epsilon_e (the fraction of the shock energy that goes into electrons) and eta (the efficiency of the mechanism producing the prompt).

X-ray variability and prediction of TeV emission in the HBL 1ES 1101-232
Anna Wolter,Fabrizio Tavecchio,Alessandro Caccianiga,G. Ghisellini,G. Tagliaferri,Tapada da Ajuda +5 more
TL;DR: In this paper, the spectral energy distribution of 1ES 1101-232 was modeled in terms of a homogeneous SSC model and the magnetic field strength of the source was derived by using a short Mark 6 pointing.

ISO observations of the BL Lac object PKS 2155-304
TL;DR: In this article, the authors obtained four light curves at 4.0, 14.3, 60 and 90 microns, and a broad-band filter spectrum from 2.8 to 170 micron.

TL;DR: In this article, the first population of stars and the processes involved in the formation of galaxies and clusters of galaxies are reconstructed. And the X-ray spectroscopy of diffuse matter has the unique capability of simultaneously probing all the elements (C through Fe), in all their ionization stages and all binding states (atomic, molecular, and solid), and thus provides a model independent survey of the metals.
