LIGO/VIRGO S200213t: upper limits from AGILE/MCAL observations
Abstract
In response to the LIGO/Virgo GW event S200213t at T0 = 2020-02-13 04:10:40.238 (UTC), a preliminary analysis of the AGILE mini calorimeter (MCAL) triggered data found no event candidates within a time interval covering -/+ 15 sec from the LIGO/Virgo T0. At the T0, about 96% of the S200213t 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 S200213t localization region, from a minimum of 1.6E-06 erg cm^-2 to a maximum of 7.5 E-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.
