Title: | Possible Quasi-Periodic Gamma-ray Emission from Blazar PG 1553+113 | Authors: | Thompson, David Cutini, Sara Ciprini, Stefano Larsson, Stefan STAMERRA, Antonio Fermi Large Area Telescope Collaboration |
Issue Date: | 2017 | Journal: | BULLETIN OF THE AMERICAN PHYSICAL SOCIETY | Volume: | APS April Meeting Abstracts | Number: | 2017 | First Page: | S4.004 | Abstract: | We report an update on a possible gamma-ray and multiwavelength nearly periodic oscillation in an active galactic nucleus. Data from the Fermi Large Area Telescope exhibit an apparent quasi-periodicity in the gamma-ray flux (E > 100 MeV) from the GeV/TeV BL Lac object PG 1553+113. The indication of a 2.18 +/- 0.08 year period gamma-ray cycle is strengthened by correlated oscillations observed in radio and optical fluxes, through data collected in the Owens Valley Radio Observatory, Tuorla, Katzman Automatic Imaging Telescope, and Catalina Sky Survey monitoring programs and Swift-UVOT. Further long-term multiwavelength monitoring of this blazar may discriminate among the possible explanations for this quasi-periodicity. | Conference Name: | APS April Meeting 2017 | Conference Place: | Washington, D.C. | Conference Date: | 28-31 January, 2017 | URI: | http://hdl.handle.net/20.500.12386/27225 | URL: | https://www.aps.org/meetings/baps/april17.cfm http://meetings.aps.org/Meeting/APR17/Session/S4.4 |
