Title: | Galactic microquasar transients with AGILE | Authors: | Munar-Adrover, Pere PIANO, Giovanni Sabatini, S. TAVANI, MARCO LUCARELLI, Fabrizio VERRECCHIA, Francesco PITTORI, Carlotta |
Issue Date: | 2017 | Volume: | 6th International Symposium on High Energy Gamma-Ray Astronomy | Editors: | Aharonian, Felix A.; Hofmann, Werner; Rieger, Frank M. | Series: | AIP CONFERENCE PROCEEDINGS | Number: | 1792 | Issue: | 1 | First Page: | 040015 | Abstract: | The AGILE satellite has been proven to be an excellent tool to study transient gamma-ray sources since it entered in a spinning operational mode in 2009. Thanks to its scanning capabilities it observes the whole sky every few hours. Several new interesting systems were discovered, such as AGL J2241+4454 in 2010, probably associated to the mysterious black-hole high-mass X-ray binary MWC 656. With a state of the art PSF and sensitivity in the 100 MeV – 1 GeV energy range, AGILE studied this system in order to identify new periods of gamma-ray activity that could be associated to the binary, and found a total of 10 flares spanning from 2008 until 2013. AGILE studied also the Cygnus region, finding evidence of a new recent gamma-ray flare from the microquasar Cygnus X-3, with a flux of ∼ 2×10−8 ph cm−2 s, during a state transition phase in the bright high-soft X-ray state. Also Cygnus X-1 was detected in the past by AGILE, although both systems are very different and show different behaviour. | Conference Name: | 6th International Symposium on High Energy Gamma-Ray Astronomy | Conference Place: | Heidelberg, Germany | Conference Date: | 11–15 July, 2016 | URI: | http://hdl.handle.net/20.500.12386/30005 | URL: | https://aip.scitation.org/doi/abs/10.1063/1.4968919 | ISSN: | 0094-243X | ISBN: | 978-0-7354-1456-3 | DOI: | 10.1063/1.4968919 | Bibcode ADS: | 2017AIPC.1792d0015M | Fulltext: | open |
