The detection of a coincident bright X-ray burst represents the first observed multiwavelength counterpart of an FRB. However, the search for similar emission at optical wavelengths has been hampered by the high inferred extinction on the line of sight. Here, we present results from the first search for second-timescale emission from the source at near-infrared (NIR) wavelengths using the Palomar Gattini-IR observing system in the J band, enabled by a novel detector readout mode that allows short exposure times of ?0.84 s with 99.9% observing efficiency. With a total observing time of ?12 hr (?47,728 images) during its 2020 outburst, we place median 3Ҡlimits on the second-timescale NIR fluence of ?18 Jy ms (13.1 AB mag). The corresponding extinction-corrected limit is ?125 Jy ms for an estimated extinction of AJ = 2.0 mag. Our observations were sensitive enough to easily detect an NIR counterpart of FRB 200428 if the NIR emission falls on the same power law as observed across its radio to X-ray spectrum. We report nondetection limits from epochs of four simultaneous X-ray bursts detected by the Insight-HXMT and NuSTAR telescopes during our observations. These limits provide the most stringent constraints to date on fluence of flares at 1014 Hz, and constrain the fluence ratio of the NIR emission to coincident X-ray bursts to RNIR ? 0.025 (fluence index ?0.35).   The FRB 121102 Host Is Atypical among Nearby Fast Radio Bursts 期刊论文  OAI收割 The Astrophysical Journal Letters, 2019, 卷号: 884, 期号: 1 作者:  Li,Ye;  Zhang,Bing;  Nagamine,Kentaro;  Shi,Jingjing   |  收藏  |  浏览/下载：52/0  |  提交时间：2019/12/02 High energy astrophysics  Radio astronomy  Radio transient sources  Radio bursts   Limits on the Weak Equivalence Principle and Photon Mass with FRB 121102 Subpulses 期刊论文  OAI收割 The Astrophysical Journal Letters, 2019, 卷号: 882, 期号: 1 作者:  Xing,Nan;  Gao,He;  Wei,Jun-Jie;  Li,Zhengxiang;  Wang,Weiyang   |  收藏  |  浏览/下载：25/0  |  提交时间：2020/03/10 Radio transient sources
