Abstract Thanks to the rapidly increasing time-domain facilities, we are entering a golden era of research on gamma-ray bursts (GRBs). In this Letter, report our observations GRB 240529A with Burst Optical Observer and Transient Exploring System, 1.5 m telescope at Observatorio de Sierra Nevada, 2.5 Wide Field Survey Telescope China, Large Binocular Telescope, Telescopio Nazionale Galileo. The prompt emission shows two comparable energetic episodes separated by quiescence time roughly 400 s....
Abstract As part of the International Asteroid Warning Network's observational exercises, we conducted a campaign to observe near-Earth asteroid 2019 XS around its close approach Earth on 2021 November 9. The goal was characterize errors in observation times reported Minor Planet Center, which become an increasingly important consideration as astrometric accuracy improves and more fast-moving asteroids are observed. exercise, total 957 observations during encounter were subsequently analyzed...
LISA will detect gravitational waves (GWs) in the milli-Hz frequency band space. Time-delay interferometry (TDI) is developed to suppress laser noise beneath acceleration and optical metrology noise. To identify stochastic GW signals, we need characterize these components entangled TDI data streams. In this work, investigate noises characterization by combining first-generation channels from Michelson Relay configurations. The are helpful lower band, configuration could effectively resolve...
Abstract Accurate radial velocity determinations of optical emission lines (i.e., [N ii ] λλ 6548, 6584, H α and [S 6717, 6731) are very important for investigating the kinematic dynamic properties nebulae. The second stage survey program Large sky Area Multi-Object fiber Spectroscopic Telescope (LAMOST) has started a sub-survey nebulae (MRS-N) which will spectroscopically observe large sample near Galactic plane. Until now, 15 MRS-N plates have been observed from September 2017 to June...
Meteoroids/asteroids could deposit energy to Earth during their entries, which arouses great concerns. Strewn field, as a product of meteoroids/asteroids breakup, comprehensively reflects the trajectory, dynamics, and physical properties meteoroids/asteroids. It typically has length several dozen kilometers. Nevertheless, recently found massive Aletai irons in northwest China comprise longest known strewn field ~430 This implies that dynamics be unique. Petrographic trace elemental studies...
Abstract The Earth close approach of near-Earth asteroid 2005 LW3 on 2022 November 23 represented a good opportunity for second observing campaign to test the timing accuracy astrometric observation. With 82 participating stations, International Asteroid Warning Network collected 1046 observations around time approach. Compared previous targeting 2019 XS, some individual observers were able significantly improve their reported observation times. In particular, U.S. surveys achieved...
The China Near-Earth Object Survey Telescope (CNEOST) conducted four photometric surveys from 2015 to 2018 using image processing and aperture photometry techniques obtain extensive light curve data on asteroids. second-order Fourier series method was selected for its efficiency in determining the rotation periods of observed Our study successfully derived 892 asteroids, with 648 those matching values recorded LCDB (for asteroids U > 2). To enhance reliability spin parameters shape...
