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).   Groundwater and streamflow sources in China's Loess Plateau on catchment scale 期刊论文  OAI收割 CATENA, 2019, 卷号: 181, 页码: 7 作者:  Li, Zhi;  Coles, Anna E.;  Xiao, Jun   |  收藏  |  浏览/下载：44/0  |  提交时间：2020/06/05 China's Loess Plateau  Groundwater source  Stable isotopes  Impacting factor  Evaporation line   Geochemical characteristics and geological significance of Cretaceous phonotephrite from the Mid-Pacific Mountains 期刊论文  OAI收割 SCIENCE CHINA-EARTH SCIENCES, 2018, 卷号: 61, 期号: 6, 页码: 745-764 作者:  Chen, Shuangshuang;  Liu, Jiaqi   |  收藏  |  浏览/下载：42/0  |  提交时间：2018/09/28 Phonotephrite  OIB-type mantle source  Carbonatite metasomatism  Line Islands  Mid-Pacific Mountain
