Icarus Revisited: An Ancient, Metal-poor Accreted Stellar Stream in the Disk of the Milky Way

open access: yesThe Astrophysical Journal
The search for accreted satellites in the Galactic disk is a challenging task, to which Gaia plays a crucial role in synergy with ground-based spectroscopic surveys. In 2021, P. Re Fiorentin et al.

ORIGIN AND EVOLUTION OF THE ABUNDANCE GRADIENT ALONG THE MILKY WAY DISK [PDF]

open access: yes, 2009
Based on a simple model of the chemical evolution of the Milky Way disk, we investigate the disk oxygen abundance gradient and its time evolution. Two star formation rates (SFRs) are considered, one is the classical Kennicutt–Schmidt law (Ψ = 0.25Σ1.4gas,

Microglia Drive Peripapillary Vascular Density Reduction in Normal Tension Glaucoma by Regulating the Rpl17/Stat5b/Apoa1 Axis

open access: yesAdvanced Science, EarlyView.
This study revealed that E50K mutant microglia drive retinal peripapillary vascular density reduction in NTG via the Rpl17/Stat5b/Apoa1 axis and identified Apoa1 as a novel suppressor of retinal vascular endothelial cells. These findings identify a potential therapeutic target for glaucoma and support the clinical potential of EA for protecting RGCs ...

An Inward-moving and Asymmetric Velocity Wave Detected in LAMOST-Gaia

open access: yesThe Astrophysical Journal Letters
The phase space, as coded by kinematic parameters and chemical abundances, is crucial for understanding the formation of the Galactic disk. Using red giant stars from the Galactic thin disk with [Fe/H] > − 0.8 and low- α ratios identified in LAMOST-Gaia,

Dust distribution in the Milky Way disk

open access: yes, 2019
To study the Galactic disk structure, we use the combination of the near-infrared survey 2MASS and Gaia DR2. We develop the Field Extinction - Distance Relation Deconvolver (FEDReD) algorithm to unravel distance and extinction. It is a Bayesian deconvolution algorithm which works field of view by field of view.

Synaptic Dysfunction in the Anterior Cingulate Cortex Underlies Pain‐Anxiety Comorbidity in a Mandibular Asymmetry Mouse Model

open access: yesAdvanced Science, EarlyView.
This study establishes a mandibular asymmetry (MA) mouse model that recapitulates chronic orofacial pain and anxiety comorbidity. Anterior cingulate cortex (ACC) hyperactivation and synaptic dysfunction are identified as central neural mechanisms underlying these pathologies, with chemogenetic inhibition of ACC CaMKII+ neurons effectively reversing ...

The Stellar Disk Structure Revealed by the Mono-age Populations of the LAMOST Red Clump Star Sample

open access: yesThe Astronomical Journal
Understanding the structure of the Galactic disk is crucial for understanding the formation and evolutionary history of the Milky Way. This study examines the structure of the Galactic disk by analyzing a sample of 138,667 primary red clump (RC) stars ...

Enhancing Anti‐Tumor Effects of Engineered Extracellular Vesicles via Endocytosis Route Switching and Interferon Response Suppression

open access: yesAdvanced Science, EarlyView.
CD19‐293‐EV can switch the CD19 endocytosis pathway from clathrin‐mediated endocytosis to aggregation‐dependent endocytosis, leading to lysosomal degradation of the CD19/EVs complex. Degradation of the EVs leads to impairment in the IFN response and enhancement in EV uptake by target cells, creating a potent feedback cycle.

The Milky Way’s Rowdy Neighbors: The Effects of the Large Magellanic Cloud and Sagittarius Dwarf on the Milky Way Disk

open access: yesThe Astrophysical Journal
The Milky Way (MW) is a barred spiral galaxy shaped by tidal interactions with its satellites. The Large Magellanic Cloud (LMC) and the Sagittarius dwarf galaxy (Sgr) are the dominant influences at the present day. This paper presents a suite of four 10 ^
