The recent CHIME/FRB and STARE2 detection of an extremely bright (fluence ~MJy ms) radio burst from the Galactic magnetar SGR 1935+2154 supports the hypothesis that (at least some) fast radio bursts are emitted by magnetars at cosmological distances. In follow-up observations totalling 522.7 h on source, we detect two bright radio bursts with fluences of 112 ± 22 Jy ms and 24 ± 5 Jy ms, respectively. Both bursts appear to be affected by interstellar scattering and we measure significant linear and circular polarization for the fainter burst. The bursts are separated in time by ~1.4 s, suggesting a non-Poissonian, clustered emission processsimilar to those seen in some repeating fast radio bursts. Together with the burst reported by CHIME/FRB and STARE2, as well as a much fainter burst seen by FAST (fluence 60 mJy ms), our observations demonstrate that SGR 1935+2154 can produce bursts with apparent energies spanning roughly seven orders of magnitude, and that the burst rate is comparable across this range. This raises the question of whether these four bursts arise from similar physical processes, and whether the fast radio burst population distribution extends to very low energies (~1030 erg, isotropic equivalent).   Multiwavelength Observations of Fast Radio Bursts 期刊论文 Universe, 2021, 卷号: 7, 页码: 76 作者:  Nicastro, Luciano;  Guidorzi, Cristiano;  Palazzi, Eliana;  Zampieri, Luca;  Turatto, Massimo 收藏  |  浏览/下载：24/0  |  提交时间：2021/11/18 r-mode instability of neutron stars in low-mass X-ray binaries: effects of Fermi surface depletion and superfluidity of dense matter 期刊论文 MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2021, 卷号: 500, 期号: 1, 页码: 1505-1511 作者:  Dong, J.
