Deciphering the Kinematic Substructure of Local Dark Matter with LAMOST K Giants
The Astrophysical JournalNumerical simulations indicate that correlations exist between the velocity distributions of stars and dark matter (DM). We study the local DM velocity distribution based on these correlations.

The Local Stellar Halo is Not Dominated by a Single Radial Merger Event
The Astrophysical Journal Letters, 2022 We use halo dwarf stars with photometrically determined metallicities that are located within 2 kpc of the Sun to identify local halo substructure. The kinematic properties of these stars do not indicate a single, dominant radial merger event (RME).

Anisotropy in the carbon monoxide (CO) line emission across the Milky Way’s disk [PDF]
Astronomy & AstrophysicsWe present a study of the CO line emission anisotropy across the Milky Way’s disk to examine the effect of stellar feedback and Galactic dynamics on the distribution of the dense interstellar medium.

FEBS Letters, EarlyView.CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

All-sky Kinematics and Chemistry of Monoceros Stellar Overdensity
The Astrophysical Journal, 2023 We explore the kinematic and chemical properties of the Monoceros stellar overdensity by combining data from the Two Micron All Sky Survey, Wide-field Infrared Survey Explorer, APOGEE, and Gaia.

Connecting Star Formation in the Milky Way and Nearby Galaxies. I. Comparability of Molecular Cloud Physical Properties [PDF]
Monthly notices of the Royal Astronomical SocietyWe used CO (2-1) and CO (1-0) data cubes to identify molecular clouds and study their kinematics and dynamics in three nearby galaxies and the inner Milky Way. When observed at similar spatial and velocity resolutions, molecular clouds in the same mass

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes
FEBS Letters, EarlyView.GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Candidate Members of the VMP/EMP Disk System of the Galaxy from the SkyMapper and SAGES Surveys
The Astrophysical Journal Supplement SeriesPhotometric stellar surveys now cover a large fraction of the sky, probe to fainter magnitudes than large-scale spectroscopic surveys, and are relatively free from the target selection biases often associated with such studies.

Alien Type Ia Supernovae from the Milky Way Merger History and One Possible Candidate: Kepler’s Supernova [PDF]
Astrophysical JournalThe Milky Way is a dynamic and evolving system shaped by numerous merger events throughout its history. These mergers bring stars with kinematic and dynamic properties differing from the main stellar population.

Galactic Forces Rule the Dynamics of Milky Way Dwarf Galaxies [PDF]
The Astrophysical Journal, 2018 Abstract Dwarf galaxies populating the Galactic halo are assumed to host the largest fractions of dark matter, as calculated from their velocity dispersions. Their major axes are preferentially aligned with the Vast Polar Structure (VPOS) that is perpendicular to the Galactic disk, and we find their velocity gradients aligned as well ...
