dc.description.abstract | FRB 180916 is a most intriguing source capable of producing repeating fast radio bursts with a periodic 16.3 day temporal pattern. The source is well positioned in a star-forming region in the outskirts of a nearby galaxy at 150 Mpc distance. In this Letter we report on the X-ray and γ-ray observations of FRB 180916 obtained by AGILE and Swift. We focused especially on the recurrent 5 day time intervals of enhanced radio bursting. In particular, we report on the results obtained in the time intervals 2020 February 3-8, 2020 February 25, 2020 March 5-10, and 2020 March 22-28 during a multiwavelength campaign involving high-energy and radio observations of FRB 180916. We also searched for temporal coincidences at millisecond timescales between the 32 known radio bursts of FRB 180916 and X-ray and MeV events detectable by AGILE. We do not detect any simultaneous event or any extended X-ray and γ-ray emission on timescales of hours/days/weeks. Our cumulative X-ray (0.3-10 keV) flux upper limit of 5 × 10<SUP>-14</SUP> erg cm<SUP>-2</SUP> s<SUP>-1</SUP> (obtained during 5 day active intervals from several 1-2 ks integrations) translates into an isotropic luminosity upper limit of L<SUB>X,UL</SUB> ∼ 1.5 × 10<SUP>41</SUP> erg s<SUP>-1</SUP>. Deep γ-ray observations above 100 MeV over a many-year timescale provide an average luminosity upper limit one order of magnitude larger. These results provide the so-far most stringent upper limits on high-energy emission from the FRB 180916 source. Our results constrain the dissipation of magnetic energy from a magnetar-like source of radius R<SUB>m</SUB>, internal magnetic field B<SUB>m</SUB>, and dissipation timescale τ<SUB>d</SUB> to satisfy the relation ${R}_{m,6}^{3}\,{B}_{m,16}^{2}\,{\tau }_{d,8}^{-1}\lesssim 1$ , where R<SUB>m,6</SUB> is R<SUB>m</SUB> in units of 10<SUP>6</SUP> cm, B<SUB>m,16</SUB> is B<SUB>m</SUB> in units of 10<SUP>16</SUP> G, and τ<SUB>d,8</SUB> in units of 10<SUP>8</SUP> s. | en_US |
