No burst was detected during a 8-hour observational campaign toward SGR J1935+2154 by FAST. Despite 29 SGR bursts detected by Fermi GBM in the time span, stringent upper limits on radio emission associated with these SGR bursts are obtained. 没看懂这个图的意思,明明像是看到了什么东西。 QQ群里...
| 快速射电暴是指遥远宇宙中突然出现的短暂而猛烈的无线电波暴发,持续时间只有几毫秒,却能够释放出相当于太阳在一整天内释放的能量。SGR 1935+2154是唯一探测到X射线脉冲辐射、快速射电暴(FRB),继而出现相位稳定射电脉冲发射的磁星,刷新了人们对磁星辐射的认识。近日,国际天文学期刊《天体物理学报增刊》(The ...
We present the results obtained from imaging observations and a search for radio pulsations toward the magnetar SGR J1935+2154 made using the Giant Metrewave Radio Telescope and the Ooty Radio Telescope. We present the high-resolution radio image of the supernova remnant (SNR) G57.2+0.8, which...

SGR 1935+2154 Swift-BAT archival data search We report on a search for previous Swift-BAT detections of SGR 1935+2154 (Cummings et al. ATel #6294). Swift-BAT has seen no subthreshold image peaks withi... JR Cummings,S Campana - 《Radiation Physics & Chemistry》 被引量: 2发表: 2000年...
An Insight-HXMT Dedicated 33 day Observation of SGR J1935+2154. I. Burst Catalog Magnetars are neutron stars with an extreme magnetic field and sometimes manifest as soft gamma-ray repeaters (SGRs). SGR J1935+2154 is one of the most pro... C Cai,WC Xue,CK Li,... - IOP Publishing ...

Deep Upper Limit on the Optical Emission during a Hard X-Ray Burst from the Magnetar SGR J1935+2154 During one of the IFI+Iqueye observing windows, a hard X-ray burst was detected with the Fermi Gamma-ray Burst Monitor. We performed a search for any significant increase in the count rat...
