Description:
Microquasars are accreting black holes or neutron stars in binary systems with associated relativistic jets. Despite their frequent outburst activity, they have never been unambiguously detected emitting high-energy gamma rays. The Fermi Large Area Telescope (LAT) has detected a variable high-energy source coinciding with the position of the x-ray binary and microquasar Cygnus X-3. Its identification with Cygnus X-3 is secured by the detection of its orbital period in gamma rays, as well as the correlation of the LAT flux with radio emission from the relativistic jets of Cygnus X-3. The gamma-ray emission probably originates from within the binary system, opening new areas in which to study the formation of relativistic jets.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fermi LAT Collaboration -- Abdo, A A -- Ackermann, M -- Ajello, M -- Axelsson, M -- Baldini, L -- Ballet, J -- Barbiellini, G -- Bastieri, D -- Baughman, B M -- Bechtol, K -- Bellazzini, R -- Berenji, B -- Blandford, R D -- Bloom, E D -- Bonamente, E -- Borgland, A W -- Brez, A -- Brigida, M -- Bruel, P -- Burnett, T H -- Buson, S -- Caliandro, G A -- Cameron, R A -- Caraveo, P A -- Casandjian, J M -- Cecchi, C -- Celik, O -- Chaty, S -- Cheung, C C -- Chiang, J -- Ciprini, S -- Claus, R -- Cohen-Tanugi, J -- Cominsky, L R -- Conrad, J -- Corbel, S -- Corbet, R -- Dermer, C D -- de Palma, F -- Digel, S W -- do Couto e Silva, E -- Drell, P S -- Dubois, R -- Dubus, G -- Dumora, D -- Farnier, C -- Favuzzi, C -- Fegan, S J -- Focke, W B -- Fortin, P -- Frailis, M -- Fusco, P -- Gargano, F -- Gehrels, N -- Germani, S -- Giavitto, G -- Giebels, B -- Giglietto, N -- Giordano, F -- Glanzman, T -- Godfrey, G -- Grenier, I A -- Grondin, M-H -- Grove, J E -- Guillemot, L -- Guiriec, S -- Hanabata, Y -- Harding, A K -- Hayashida, M -- Hays, E -- Hill, A B -- Hjalmarsdotter, L -- Horan, D -- Hughes, R E -- Jackson, M S -- Johannesson, G -- Johnson, A S -- Johnson, T J -- Johnson, W N -- Kamae, T -- Katagiri, H -- Kawai, N -- Kerr, M -- Knodlseder, J -- Kocian, M L -- Koerding, E -- Kuss, M -- Lande, J -- Latronico, L -- Lemoine-Goumard, M -- Longo, F -- Loparco, F -- Lott, B -- Lovellette, M N -- Lubrano, P -- Madejski, G M -- Makeev, A -- Marchand, L -- Marelli, M -- Max-Moerbeck, W -- Mazziotta, M N -- McColl, N -- McEnery, J E -- Meurer, C -- Michelson, P F -- Migliari, S -- Mitthumsiri, W -- Mizuno, T -- Monte, C -- Monzani, M E -- Morselli, A -- Moskalenko, I V -- Murgia, S -- Nolan, P L -- Norris, J P -- Nuss, E -- Ohsugi, T -- Omodei, N -- Ong, R A -- Ormes, J F -- Paneque, D -- Parent, D -- Pelassa, V -- Pepe, M -- Pesce-Rollins, M -- Piron, F -- Pooley, G -- Porter, T A -- Pottschmidt, K -- Raino, S -- Rando, R -- Ray, P S -- Razzano, M -- Rea, N -- Readhead, A -- Reimer, A -- Reimer, O -- Richards, J L -- Rochester, L S -- Rodriguez, J -- Rodriguez, A Y -- Romani, R W -- Ryde, F -- Sadrozinski, H F-W -- Sander, A -- Saz Parkinson, P M -- Sgro, C -- Siskind, E J -- Smith, D A -- Smith, P D -- Spinelli, P -- Starck, J-L -- Stevenson, M -- Strickman, M S -- Suson, D J -- Takahashi, H -- Tanaka, T -- Thayer, J B -- Thompson, D J -- Tibaldo, L -- Tomsick, J A -- Torres, D F -- Tosti, G -- Tramacere, A -- Uchiyama, Y -- Usher, T L -- Vasileiou, V -- Vilchez, N -- Vitale, V -- Waite, A P -- Wang, P -- Wilms, J -- Winer, B L -- Wood, K S -- Ylinen, T -- Ziegler, M -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1512-6. doi: 10.1126/science.1182174.
