Enhanced gamma-ray activity from Eta Carinae detected by AGILE

AGILE is detecting gamma-ray emission above 100 MeV from a source positionally consistent with the colliding wind binary Eta Carinae:
New ATel issued: “Enhanced gamma-ray activity from Eta Carinae”, ATel #13329 (G. Piano et al.).

This high-energy gamma-ray activity is consistent with the emission pattern of October 2008, when AGILE observed a peak gamma-ray emission from Eta Carinae a few months before the periastron passage of January 2009 (Tavani et al., ApJ 698, L142, 2009). The next periastron passage should occur by the end of February 2020.
