Kavli Affiliate: Renxin Xu | First 5 Authors: Chen Zhang, Yong Gao, Cheng-Jun Xia, Renxin Xu, | Summary: Solid states of strange-cluster matter called strangeon matter can form strangeon stars that are highly compact. We show that strangeon matter and strangeon stars can be recast into dimensionless forms by a simple reparametrization and rescaling, through […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Huaisong Zhao, Peng Zou, Feng Yuan, , | Summary: By calculating the dynamical structure factor along the high symmetry directions in the Brillouin zone, the dynamical excitations of attractive Fermi-Hubbard model in a two-dimensional square optical lattice are studied with random phase approximation. {Two kinds of collective […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Zhen Cao, F. Aharonian, Q. An, Axikegu, Y. X. Bai | Summary: The diffuse Galactic $gamma$-ray emission, mainly produced via interactions between cosmic rays and the diffuse interstellar medium, is a very important probe of the distribution, propagation, and interaction of cosmic rays in the Milky […]

In this work […]
Shengqi Yang, Fangzhou Jiang, Andrew Benson, Yi-Ming Zhong, Charlie Mace | Summary: [[{“value”:”One necessary step for probing the nature of self-interacting dark matter (SIDM) particles with astrophysical observations is to pin down any possible velocity dependence in the SIDM cross section. Major challenges for achieving this goal include eliminating, or mitigating, the impact of the […]

Kavli Affiliate: Xian Chen | First 5 Authors: Han Yan, Xian Chen, Alejandro Torres-Orjuela, , | Summary: The possibility of forming gravitational-wave sources with high center-of-mass (c.m.) velocities in the vicinity of supermassive black holes requires us to develop a method of deriving the waveform in the observer’s frame. Here we show that in the […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Chun Wang, Yang Huang, Yutao Zhou, Huawei Zhang, | Summary: We construct a catalogue of stellar masses and ages for 696,680 red giant branch (RGB) stars, 180,436 primary red clump (RC) stars, and 120,907 secondary RC stars selected from the LAMOST,DR8. The RGBs, primary RCs, and secondary […]
