Abstract As one paper in a series reporting on large reverberation mapping campaign of super-Eddington accreting massive black holes (SEAMBHs) active galactic nuclei (AGNs), we present the results 10 SEAMBHs monitored spectroscopically during 2015–2017. Six them are observed for first time, and have generally higher 5100 Å luminosities than our from 2012 to 2015; remaining four repeat observations check if their previous lags change. Similar SEAMBHs, H β time newly objects shorter values...
Abstract. With the increase in economic development over past thirty years, many large cities eastern and southwestern China are experiencing increased haze events atmospheric pollution, causing significant impacts on regional environment even climate. However, knowledge aerosol physical chemical properties heavy conditions is still insufficient. In this study, two winter Beijing that occurred 2011 2012 were selected investigated by using ground-based remote sensing measurements. We used a...
Abstract We report on the spectral behavior of first Galactic ultraluminous X-ray pulsar Swift J0243.6+6124 with NuSTAR observations during its 2017–2018 outburst. At sub-Eddington levels, source spectrum is characterized by three emission components: from accretion column, hot spot, and a broad iron line region. When above Eddington limit, spot temperature increases features two more blackbody components. One component has radius 10–20 km likely originate top column. The other one saturates...
Abstract We report results of the first reverberation mapping campaign I Zwicky 1 during 2014–2016, which showed unambiguous reverberations broad H β line emission in varying optical continuum. From analysis using several methods, we obtain a lag <?CDATA ${\tau }_{{\rm{H}}\beta }={37.2}_{-4.9}^{+4.5}\,\mathrm{days}$?> . Taking virial factor ${f}_{{}_{\mathrm{BLR}}}=1$?> , find black hole mass ${M}_{\bullet }={9.30}_{-1.38}^{+1.26}\times {10}^{6}{M}_{\odot }$?> from mean spectra. The...
The solar X-ray and Extreme Ultraviolet Imager (X-EUVI), developed by the Changchun Institute of Optics, Fine Mechanics Physics, Chinese Academy Sciences (CIOMP), is first space-based ultraviolet (EUV) imager China loaded on Fengyun-3E (FY-3E) satellite supported Meteorological Administration (CMA) for observation. Since started work July 11, 2021, X-EUVI has obtained many images. instrument employs an innovative dual-band design to monitor a much larger temperature range Sun, which covers...
Abstract The recently discovered neutron star transient Swift J0243.6+6124 has been monitored by the Hard X-ray Modulation Telescope . Based on obtained data, we investigate broadband spectrum of source throughout outburst. We estimate flux and search for possible cyclotron line in spectrum. However, no evidence line-like features is found up to 150 keV. In absence any its energy spectrum, magnetic field based observed spin evolution applying two accretion torque models. both cases, get...
Abstract Owing to the narrow energy band of Swift Burst Alert Telescope (BAT), several urgent issues remain unsolved. We systematically study properties a refined sample 283 Swift/BAT gamma-ray bursts (GRBs) with well-measured spectral peak ( E p ) at high confidence level greater than 3 σ . find that duration T 90 distribution still exhibits an evident bimodality more reliable boundary ≃ 1.06 s instead 2 as found for previously contaminated samples, including without well-peaked spectra,...
Silver indium cadmium (Ag–In–Cd) control rod is widely used in pressurized water reactor nuclear power plants, and it continuously consumed a high neutron flux environment. The mass ratio of 107 Ag the Ag–In–Cd 41.44%. To accurately calculate consumption value rod, reliable reaction cross section required. Meanwhile, also an important weak r nucleus. Thus, sections for induced interactions with are very both energy astrophysics. (n, γ ) has been measured range 1–60 eV using back streaming...

We present the observational results from a detailed timing analysis of black hole candidate Swift J1658.2-4242 during its 2018 outburst with observations Hard X-ray Modulation Telescope (Insight-HXMT), Neutron Star Interior Composition Explorer (NICER) and AstroSat in 0.1-250keV. The evolution intensity, hardness integrated fractional root mean square (rms) observed by Insight-HXMT NICER are presented this paper.
