AGILE confirms intense gamma-ray activity above 100 MeV from the blazars PKS 0514-459 and TXS 1700+685, as previously reported by Fermi-LAT team with ATel #14633.
Integrating from 2021-05-14 07:00 UT to 2021-05-16 07:00 UT, a maximum likelihood analysis yields a 5 sigma detection positionally consistent with the blazar PKS 0514-459, with a source flux F = (2.3 +/- 0.7) x 10e-6 ph/cm^2/s (E > 100 MeV). This detection partially includes the time of the GeV flare reported recently by Fermi/LAT from the same source.
Integrating in the same time period, a maximum likelihood analysis yields a 5 sigma detection positionally consistent with the blazar TXS 1700+685, with a source flux F = (2.0 +/- 0.6) x 10e-6 ph/cm^2/s (E > 100 MeV). This detection partially includes the time of the GeV flare reported recently by Fermi/LAT from the same source.
The AGILE-GRID detection was obtained while AGILE is observing in spinning mode, surveying a large fraction of the sky each day.
Multifrequency follow-up observations are strongly encouraged.
The source can be monitored with the public mobile application "AGILEScience" developed by the AGILE Team, available for both Android and iOS devices.
