The Impact of Inelastic Collisions with Hydrogen on NLTE Copper Abundances in Metal-Poor Stars
Xiaodong Xu, Jianrong Shi, Xiaofeng Wang
We investigate the non-local thermodynamic equilibrium (NLTE) analysis for \ion{Cu}{1} lines with the updated model atom that includes quantum-mechanical rate coefficients of Cu\,$…
LAMOST/HRS Spectroscopic Analysis of Two New Li-rich Giants
Zeming Zhou, Jianrong Shi, Hongliang Yan +9
Two Li-rich candidates, TYC 1338-1410-1 and TYC 2825-596-1, were observed with the new high-resolution echelle spectrograph, LAMOST/HRS. Based on the high-resolution and high-signa…
Most Lithium-rich Low-mass Evolved Stars Revealed as Red Clump stars by Asteroseismology and Spectroscopy
Hong-Liang Yan, Yu-Tao Zhou, Xianfei Zhang +19
Lithium has confused scientists for decades at almost each scale of the universe. Lithium-rich giants are peculiar stars with lithium abundances over model prediction. A large frac…
Towards the full realization of the RIBLL2 beam line at the HIRFL-CSR complex
Bao-Hua Sun, Jian-Wei Zhao, Xue-Heng Zhang +31
The RIBLL2 in-flight separator at IMP, the secondary beam line between two storage rings at the \blue{\uwave{Heavy Ion Research Facility in Lanzhou (HIRFL-CSR)}}, has been commissi…
Constraining the interaction between dark sectors with future HI intensity mapping observations
Xiaodong Xu, Yin-Zhe Ma, Amanda Weltman
We study a model of interacting dark matter and dark energy, in which the two components are coupled. We calculate the predictions for the 21-cm intensity mapping power spectra, an…
Signature of the interaction between dark sectors in the reionization process
Rui An, Xiaodong Xu, Jun Zhang +2
We consider the reionization process in a cosmological model in which dark matter interacts with dark energy. Using a semi-analytical reionization model, we compute the evolution o…
Constraints on interacting dark energy models from Planck 2015 and redshift-space distortion data
André A. Costa, Xiao-Dong Xu, Bin Wang +1
We investigate phenomenological interactions between dark matter and dark energy and constrain these models by employing the most recent cosmological data including the cosmic micr…
Dynamical analysis of modified gravity with nonminimal gravitational coupling to matter
Rui An, Xiaodong Xu, Bin Wang +1
We perform a phase space analysis of a generalized modified gravity theory with nonminimally coupling between geometry and matter. We apply the dynamical system approach to this ge…
Early dark energy and its interaction with dark matter
Bo-Yu Pu, Xiao-Dong Xu, Bin Wang +1
We study a class of early dark energy models which has substantial amount of dark energy in the early epoch of the universe. We examine the impact of the early dark energy fluctuat…
Testing the tensor-vector-scalar Theory with the latest cosmological observations
Xiao-dong Xu, Bin Wang, Pengjie Zhang
The tensor-vector-scalar (TeVeS) model is considered a viable theory of gravity. It produces the Milgrom's modified Newtonian dynamics in the nonrelativistic weak field limit and i…
Testing the Interaction between Dark Energy and Dark Matter with Planck Data
André A. Costa, Xiao-Dong Xu, Bin Wang +2
Interacting Dark Energy and Dark Matter is used to go beyond the standard cosmology. We base our arguments on Planck data and conclude that an interaction is compatible with the ob…
The effect of Dark Matter and Dark Energy interactions on the peculiar velocity field and the kinetic Sunyaev-Zel'dovich effect
Xiao-Dong Xu, Bin Wang, Pengjie Zhang +1
The interaction between Dark Matter and Dark Energy has been proposed as a mechanism to alleviate the coincidence problem. We analyze the effect of the interaction on the evolution…
The signature of the scattering between dark sectors in large scale cosmic microwave background anisotropies
Xiao-Dong Xu, Bin Wang, Elcio Abdalla
We study the interaction between dark sectors by considering the momentum transfer caused by the dark matter scattering elastically within the dark energy fluid. Describing the dar…
