Filtered pseudo-scalar dark matter and gravitational waves from first order phase transition
Wei Chao, Xiu-Fei Li, Lei Wang
If dark matter (DM) acquires mass during a first order phase transition, there will be a filtering-out effect when DM enters the expanding bubble. In this paper we study the filter…
Age-metallicity dependent stellar kinematics of the Milky Way disc from LAMOST and Gaia

Based on Insight-HXMT data, we report on the pulse fraction evolution during the 2017-2018 outburst of the newly discovered first Galactic ultraluminous X-ray source (ULX) Swift J0…
Mode Angular Degree Identification in Subgiant Stars with Convolutional Neural Networks based on Power Spectrum
Minghao Du, Shaolan Bi, Xianfei Zhang +3
Identifying the angular degrees of oscillation modes is essential for asteroseismology and depends on visual tagging before fitting power spectra in a so-called peakbagging ana…
Measuring the viscosity of dark matter with strongly lensed gravitational waves
Shuo Cao, Jingzhao Qi, Marek Biesiada +3
Based on the strongly lensed gravitational waves (GWs) from compact binary coalescence, we propose a new strategy to examine the fluid shear viscosity of dark matter (DM) in the gr…
Improved deep learning techniques in gravitational-wave data analysis
Heming Xia, Lijing Shao, Junjie Zhao +1
In recent years, convolutional neural network (CNN) and other deep learning models have been gradually introduced into the area of gravitational-wave (GW) data processing. Compared…
Asteroseismology of luminous red giants with Kepler. II. Dependence of mass loss on pulsations and radiation
Jie Yu, Saskia Hekker, Timothy R. Bedding +5
Mass loss by red giants is an important process to understand the final stages of stellar evolution and the chemical enrichment of the interstellar medium. Mass-loss rates are thou…
Structure-preserving, energy stable numerical schemes for a liquid thin film coarsening model
Juan Zhang, Cheng Wang, Steven M. Wise +1
In this paper, two finite difference numerical schemes are proposed and analyzed for the droplet liquid film model, with a singular Leonard-Jones energy potential involved. Both fi…
Giant X-ray and optical Bump in GRBs: evidence for fall-back accretion model
Litao Zhao, He Gao, WeiHua Lei +2
The successful operation of dedicated detectors has brought us valuable information for understanding the central engine and the progenitor of gamma-ray bursts (GRBs). For instance…

Zezhou Hu, Zhen Zhong, Peng-Cheng Li +2
In this work, taking the QED effect into account, we investigate the shadows of the static black hole with magnetic monopoles and neutral black holes in magnetic fields through the…
Neutron Star Mergers in AGN Accretion Disks: Cocoon and Ejecta Shock Breakouts
Jin-Ping Zhu, Bing Zhang, Yun-Wei Yu +1
Neutron star mergers are believed to occur in accretion disks around supermassive black holes. Here we show that a putative jet launched from the merger of a binary neutron star (B…
Evolved Massive Stars at Low-metallicity III. A Source Catalog for the Large Magellanic Cloud
Ming Yang, Alceste Z. Bonanos, Biwei Jiang +9
We present a clean, magnitude-limited (IRAC1 or WISE115.0 mag) multiwavelength source catalog for the LMC. The catalog was built upon crossmatching () and deblending ($3…
