“…GRB 090618 is characterised by a remarkable fluence of (3.2 ± 0.6) −5 erg cm −2 , measured by MCAL in the energy band between 350 keV and 100 MeV. The GRB has a steep spectrum in the same energy band, with a photon index of -3.16 [20] by MCAL, and is not detected in gamma-rays by the GRID. The interested reader can find the details and the complete analysis of the upper limits of GRBs in the GRID in a forthcoming paper [18].…”

The AGILE satellite, in orbit since 2007, localized up to October 2009 about 1 Gamma Ray Burst (GRB) per month with the hard X-ray imager SuperAGILE (18 -60 keV) (with a rate reduced by a factor 2-3 in spinning mode) and is detecting around 1 GRB per week with the non-imaging Mini-Calorimeter (MCAL, 0.35 -100 MeV). Up to now the AGILE Gamma Ray Imaging Detector firmly detected four GRBs in the energy band between 20 MeV and few GeV. In this paper we review the status of the GRBs observation with AGILE and discuss the upper limits in the gamma-ray band of the non-detected events. Moreover AGILE is detecting hundreds of Terrestrial Gamma-ray Flashes (TGFs) with the MCAL instrument. Thanks to the MCAL energy range extended up to 100MeV and its flexible trigger logic on sub-millisecond time scales, AGILE is adding a wealth of observations which pose severe constrains on production models. In this presentation we will describe the characteristics of the AGILE TGF sample. Finally we present the first precise localization study of TGFs from space, carried out at gamma-ray energies above 20 MeV with the AGILE gamma-ray imager.

“…A remarkable case of this behaviour is the long GRB 090618, localised by Swift [19] and also by SuperAGILE (in a consistent position) and detected by the MCAL [20]. GRB 090618 is characterised by a remarkable fluence of (3.2 ± 0.6) −5 erg cm −2 , measured by MCAL in the energy band between 350 keV and 100 MeV.…”

“…This was an extremely bright burst that also triggered Fermi -GBM (McBreen 2009), Super-AGILE (Longo et al 2009), and Konus-Wind (Golenetskii et al 2009). The burst's X-ray afterglow was detected by the XRT and the burst's optical afterglow was detected by UVOT.…”

Abstract. The GRB-SNe connection has been strengthened since 2008 by the detection of 6 additional GRB-SNe at both local and cosmological redshifts. This review summarizes the recent observations of SNe associated with GRBs 081007, 090618, 091127, 100316D, 101219B and 111211A, as well as the observations of SN 2008D, which was associated with a bright X-ray flash (XRF 080109) and may represent a link between "plain" SN and GRB-SNe. It is now clear that most -if not all -long-duration GRBs are produced by the core collapse of massive stars.
