It has long been speculated that magnetars are the engine powering repeating bursts from FRB sources4-13, but no convincing evidence has been collected so far14. Recently, the Galactic magnetar SRG 1935+2154 entered an active phase by emitting intense soft íray bursts15. One FRB-like event with two peaks (FRB 200428) and a luminosity slightly lower than the faintest extragalactic FRBs was detected from the source, in association with a soft íray/hard-X-ray flare18-21. Here we report an eight-hour targeted radio observational campaign comprising four sessions and assisted by multi-wavelength (optical and hard-X-ray) data. During the third session, 29 soft-íray repeater (SGR) bursts were detected in íray energies. Throughout the observing period, we detected no single dispersed pulsed emission coincident with the arrivals of SGR bursts, but unfortunately we were not observing when the FRB was detected. The non-detection places a fluence upper limit that is eight orders of magnitude lower than the fluence of FRB 200428. Our results suggest that FRB-SGR burst associations are rare. FRBs may be highly relativistic and geometrically beamed, or FRB-like events associated with SGR bursts may have narrow spectra and characteristic frequencies outside the observed band. It is also possible that the physical conditions required to achieve coherent radiation in SGR bursts are difficult to satisfy, and that only under extreme conditions could an FRB be associated with an SGR burst.   Constant cyclotron line energy in Hercules X-1 - Joint Insight-HXMT and NuSTAR observations 期刊论文  OAI收割 Journal of High Energy Astrophysics, 2019, 卷号: 23, 页码: 29-32 作者:  HXMT   |  收藏  |  浏览/下载：52/0  |  提交时间：2022/02/08 Stars: neutron star  Pulsars: binary(Her X-1)  X-rays: stars  Astrophysics - High Energy Astrophysical Phenomena  Abstract: The long-term evolution of the centroid energy of the CRSF in Her X-1 is still a mystery. We report a new measurement from a campaign between Insight-HXMT and NuSTAR performed in February 2018. Generally, the two satellites show well consistent results of timing and spectral properties. The joint spectral analysis confirms that the previously observed long decay phase has ended, and that the line energy instead keeps constant around 37.5 keV after flux correction.   Super-Eddington accreting massive black holes explore high-z cosmology: Monte-Carlo simulations 期刊论文  OAI收割 PHYSICAL REVIEW D, 2018, 卷号: 97, 期号: 12, 页码: 123502 作者:  Cai, RG;  Guo, ZK;  Huang, QG;  Yang, T   |  收藏  |  浏览/下载：50/0  |  提交时间：2018/12/27 ACTIVE GALACTIC NUCLEI  BROAD-LINE REGION  REVERBERATION MAPPING CAMPAIGN  BARYON ACOUSTIC-OSCILLATIONS  GALAXIES  RATES  DISKS  II.  CONSTRAINTS  CONSTANT   Boosting water conservation by improving campaign: Evidence from a field study in China 期刊论文  OAI收割 URBAN WATER JOURNAL, 2018, 卷号: 15, 期号: 10, 页码: 966-973 作者:  Sun, Yan;  Li, Pengna;  She, Shengxiang;  Eimontaite, Iveta;  Yang, Bo   |  收藏  |  浏览/下载：56/0  |  提交时间：2019/04/22 Water conservation  campaign  field study  quantitative information  norm information   Global tidal mapping from observations of a radar campaign 期刊论文  OAI收割 ADVANCES IN SPACE RESEARCH, 2017, 卷号: 60, 期号: 1, 页码: 130-143 作者:  Yu, You;  Wan, Weixing;  Reid, Iain M.;  Chen, Jinsong;  Vincent, Robert A.   |  收藏  |  浏览/下载：80/0  |  提交时间：2017/11/16 Radar campaign  MLT tides  Hough mode decomposition  Pole-to-pole tidal mapping   A first comprehensive evaluation of China's GNSS-R airborne campaign: part II-river remote sensing 期刊论文  OAI收割 SCIENCE BULLETIN, 2015, 卷号: 60, 期号: 17, 页码: 1527-1534 作者:  Bai, Weihua;  Xia, Junming;  Wan, Wei;  Zhao, Limin;  Sun, Yueqiang 收藏  |  浏览/下载：22/0  |  提交时间：2015/10/29 GNSS-R  River height  Airborne campaign  Flow velocity   Initial results of China's GNSS-R airborne campaign: soil moisture retrievals 期刊论文  OAI收割 SCIENCE BULLETIN, 2015, 卷号: 60, 期号: 10, 页码: 964-971 作者:  Wan, Wei;  Bai, Weihua;  Zhao, Limin;  Long, Di;  Sun, Yueqiang 收藏  |  浏览/下载：31/0  |  提交时间：2015/09/28 GNSS-R  Soil moisture  Airborne campaign  The Yellow River  GPS   Initial results of China's GNSS-R airborne campaign: soil moisture retrievals 期刊论文  OAI收割 SCIENCE BULLETIN, 2015, 卷号: 60, 期号: 10, 页码: 445-453 作者:  Wan, Wei;  Bai, Weihua;  Zhao, Limin;  Long, Di;  Sun, Yueqiang 收藏  |  浏览/下载：22/0  |  提交时间：2016/04/20 GNSS-R  Soil moisture  Airborne campaign  The Yellow River  GPS
