Four-dimensional Vibrational Spectroscopy for Nanoscale Mapping of Phonon Dispersion in BN Nanotubes
Ruishi Qi, Ning Li, Jinlong Du +8
Direct measurement of local phonon dispersion in individual nanostructures can greatly advance our understanding of their electrical, thermal, and mechanical properties. However, s…
A Low-Mass Stellar-Debris Stream Associated with a Globular Cluster Pair in the Halo
Zhen Yuan, Jiang Chang, Timothy C. Beers +1
There are expected to be physical relationships between the globular clusters (GCs) and stellar substructures in the Milky Way, not all of which have yet been found. We search for…
Existence of coLegendrians in contact -manifolds
Yang Huang
We introduce the notion of coLegendrian submanifold in a contact manifold as a middle-dimensional coisotropic submanifold and study its existence in dimension via contact Morse…
Dependency of Sliding Friction for Two Dimensional Systems on Electronegativity
Jianjun Wang, Avinash Tiwari, Yang Huang +2
We study the role of electronegativity in sliding friction for five different two dimensional (2D) monolayer systems using density functional theory (DFT) with van der Waals (vdW)…
Mapping the Galactic disk with the LAMOST and Gaia Red clump sample: I: precise distances, masses, ages and 3D velocities of 140000 red clump stars
Yang Huang, Ralph Schonrich, Huawei Zhang +10
We present a sample of 140,000 primary red clump (RC) stars of spectral signal-to-noise ratios higher than 20 from the LAMOST Galactic spectroscopic surveys, selected based…
A Catalog of RV Variable Star Candidates from LAMOST
Zhijia Tian, Xiaowei Liu, Haibo Yuan +14
RV variable stars are important in astrophysics. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectroscopic survey has provided ~ 6.5 million stellar spec…
Scattering of massless scalar field by charged dilatonic black holes
Yang Huang, Hongsheng Zhang
Wave propagations in the presence of black holes is a significant problem both in theoretical and observational aspects, especially after the discovery of gravitational wave and co…
Astronomical Site Monitoring System at Lijiang Observatory
Yu-Xin Xin, Jin-Ming Bai, Bao-Li Lun +18
We installed two sets of Astronomical Site Monitoring System(ASMS) at Lijiang Observatory(GMG), for the running of the 2.4-meter Lijiang optical telescope(LJT) and the 1.6-meter Mu…
Inequalities for generalized matrix function and inner product
Yang Huang, Yongtao Li, Lihua Feng +1
We present inequalities related to generalized matrix function for positive semidefinite block matrices. We introduce partial generalized matrix functions corresponding to partial…
Extensions of Fiedler-Markham's inequality and Thompson's inequality
Yongtao Li, Yang Huang, Lihua Feng +1
We present some new inequalities related to determinant and trace for positive semidefinite block matrices by using symmetric tensor product, which are extensions of Fiedler-Markha…
Probing the conformal invariance around the nonsingular static spherical black holes with waves
Rui-Hui Lin, Rui Jiang, Yang Huang +1
Conformal invariance can ameliorate or eliminate the singularities residing in the black holes, and may still exist in the strong gravity regimes close to these black holes. In thi…
Some properties for morphism of representations
Yang Huang, Yongtao Li, Weijun Liu +1
Let and be representations of finite group . A linear map is called a morphism from to if it satisfys for each…
A dynamical construction of Liouville domains
Yang Huang
We first present a general construction of Liouville domains as partial mapping tori. Then we study two examples where the (partial) monodromies exhibit certain hyperbolic behavior…
The LAMOST spectroscopic survey of star clusters in M31. II. Metallicities, ages and masses
Chen Bingqiu, Liu Xiaowei, Xiang Maosheng +14
We select from Paper I a sample of 306 massive star clusters observed with the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) in the vicinity fields of M31 and…

Maosheng Xiang, Xiaowei Liu, Haibo Yuan +17
We introduce the LAMOST Stellar Parameter Pipeline at Peking University --- LSP3, developed and implemented for the determinations of radial velocity and stellar atmosp…
Relative Flux Calibration of the LAMOST Spectroscopic Survey of the Galactic Anti-center
Maosheng Xiang, Xiaowei Liu, Haibo Yuan +17
We have developed and implemented an iterative algorithm of flux calibration for the LAMOST Spectroscopic Survey of the Galactic anti-center (LSS-GAC). For a given LSS-GAC plate, t…
