We execute a detailed spectral-timing study of Cygnus X-1 in the low/hard, intermediate and high/soft states with Hard X-ray Modulation Telescope observations. The broad band energy spectra fit well "truncated disk model" inner boundary accretion stays within $\sim$10 \textit R$_{\rm g}$ moves inward as source softens. Through studying PDS, rms Fourier-frequency component resolved spectroscopy, we find that variations are generated two different regions for each state. discover major role...
LIGO/Virgo S190814bv is the first high-probability neutron star - black hole (NSBH) merger candidate, whose gravitational waves (GWs) triggered detectors at 21:10:39.012957 UT, 14 August 2019. It has a probability $>99\%$ of being an NSBH merger, with low false alarm rate (FAR) 1 per 1.559e+25 years. For electromagnetic counterparts (especially short gamma-ray bursts (GRBs)) are generally expected. However, no counterpart been found in extensive follow-up observing campaign. In present work,...
Rapid response and short time latency are very important for Time Domain Astronomy, such as the observations of Gamma-ray Bursts (GRBs) electromagnetic (EM) counterparts gravitational waves (GWs). Based on near real-time Fermi/GBM data, we developed a low-latency pipeline to automatically calculate temporal spectral properties GRBs. With this pipeline, some parameters can be obtained, T90 fluence, within ∼ 20 min after GRB trigger. For 90% GRBs, fluence consistent with GBM catalog results 2σ...
