THE RADIAL PROFILE AND FLATTENING OF THE MILKY WAY’S STELLAR HALO TO 80 kpc FROM THE SEGUE K-GIANT SURVEY [PDF]
, 2015 We characterize the radial density, metallicity, and flattening profile of the Milky Way’s stellar halo, based on the large sample of spectroscopically confirmed giant stars from SDSS/SEGUE-2, spanning galactocentric radii 10 kpc ≤ rGC ≤ 80 kpc.

FEBS Open Bio, EarlyView.Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Metallicity and α-abundance for 48 Million Stars in Low-extinction Regions in the Milky Way
The Astrophysical JournalWe estimate ([M/H], [ α /M]) for 48 million giants and dwarfs in low-dust extinction regions from the Gaia DR3 XP spectra by using tree-based machine learning models trained on APOGEE DR17 and a metal-poor star sample from Li et al.

Detection of Multiple Phase Space Overdensities of GSE Stars by Orbit Integration
The Astrophysical Journal, 2023 In N -body simulations, nearly radial mergers can form shell-like overdensities in the sky position and phase space ( r − v _r ) due to the combination of dynamical friction and tidal stripping.

Galactic googly: the rotation-metallicity bias in the inner stellar halo of the Milky Way [PDF]
, 2017 The first and second moments of stellar velocities encode important information about the formation history of the Galactic halo. However, due to the lack of tangential motion and inaccurate distances of the halo stars, the velocity moments in the ...

FEBS Open Bio, EarlyView.IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

The birth of the Milky Way: the in-situ halo and early thick disk as uncovered by accurate stellar ages with Gaia [PDF]
, 2019 As Milky Way-like galaxies form, smaller stellar systems accrete onto the main galactic progenitor, assembling a kinematically hot, spheroidal-like stellar halo surrounding the galactic disc.
