Observational Constraints of Radial Migration in the Galactic Disk Driven by the Slowing Bar
The Astrophysical Journal LettersRadial migration is an important dynamical effect that has reshaped the Galactic disk, but its origin has yet to be elucidated. In this work, we present evidence that resonant dragging by the corotation of a decelerating bar could be the main driver of ...

The Magellanic Stream in Modified Newtonian Dynamics
, 2006 The dynamics of the Magellanic Stream (MS) as a series of clouds extending from the Magellanic Clouds (MCs) to the south Galactic pole is affected by the distribution and the amount of matter in the Milky Way. We calculate the gravitational effect of the

TLR Agonist Nano Immune Therapy Clears Peritoneal and Systemic Ovarian Cancer
Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.Intraperitoneal administration of immunogenic Toll‐like receptor agonist‐modified mesoporous silica nanoparticles leads to rapid internalization by ascites myeloid cells with trafficking to fat‐associated lymphoid clusters. Activation of myeloid cells counters suppressive immune mechanisms associated with peritoneal metastasis, leading to regional and ...

Synthetic Gaia DR3 Surveys from the FIRE Cosmological Simulations of Milky Way-mass Galaxies
The Astrophysical JournalThe third data release (DR3) of Gaia has provided a fivefold increase in the number of radial velocity measurements of stars, as well as a stark improvement in parallax and proper motion measurements.

The Gaia inertial reference frame and the tilting of the Milky Way disk
, 2014 While the precise relationship between the Milky Way disk and the symmetry planes of the dark matter halo remains somewhat uncertain, a time-varying disk orientation with respect to an inertial reference frame seems probable.

The Astrophysical JournalThe main-sequence turnoff (MSTO) stars well preserve the chemical properties where they were born, making them ideal tracers for studying the stellar population. We perform a detailed chemo-dynamical analysis on moderately metal-poor (−2.0

Advanced Healthcare Materials, EarlyView.Engineered 3D‐Cad/IL6‐MSC, developed through synergistic hE/N‐cad‐Fc and IL‐6 preconditioning, show remarkable therapeutic potential for systemic sclerosis. These engineered MSC aggregates reduce pathogenic inflammatory cell infiltration and restore immune balance among CD4+ T‐cell populations, offering a promising approach to optimize MSC based ...

The Extremely Metal-rich Knot of Stars at the Heart of the Galaxy
The Astrophysical JournalWe show with Gaia XP spectroscopy that extremely metal-rich (EMR) stars in the Milky Way ([M/H] _XP ≳ 0.5) are largely confined to a tight “knot” at the center of the Galaxy. This EMR knot is round in projection, has a fairly abrupt edge near R _GC,proj ∼

Gas dynamics and large-scale morphology of the Milky Way galaxy [PDF]
, 2017 We present a new model for the gas dynamics in the galactic disc inside the orbit of the Sun. Quasi-equilibrium flow solutions are determined in the gravitational potential of the deprojected COBE near-infrared bar and disc, complemented by a central ...
