Data pubblicazione: | 2019 | Rivista: | GRB Coordinates Network | Numero: | 24933 | Da pagina:: | 1 | Abstract: | In response to the LIGO/Virgo GW event S190630ag at T0 = 2019-06-30 18:52:05 (UT), a preliminary analysis of the AGILE minicalorimeter (MCAL) triggered data found no event candidates within a time interval covering -/+ 15 sec from the LIGO/Virgo T0. At the T0, about 60% of the S190630ag 90% c.l. localization region was accessible to the AGILE MCAL. Three-sigma upper limits (ULs) are obtained for a 1 s integration time at different celestial positions within the accessible S190630ag localization region, from a minimum of 1.6E-06 erg cm^-2 to a maximum of 7.4E-06 erg cm^-2 (assuming as spectral model a single power law with photon index 1.5). The AGILE-MCAL detector is a CsI detector with a 4 pi FoV, sensitive in the energy range 0.4-100 MeV. Additional analysis of AGILE data is in progress. | URI: | http://hdl.handle.net/20.500.12386/34937 | URL: | https://gcn.gsfc.nasa.gov/gcn3/24933.gcn3 | Bibcode ADS: | 2019GCN.24933....1P | Fulltext: | open |
