Asymmetric Mean Metallicity Distribution of the Milky Way’s Disk [PDF]

The Astrophysical Journal Letters, 2019
Abstract I present the mean metallicity distribution of stars in the Milky Way based on photometry from the Sloan Digital Sky Survey. I utilize an empirically calibrated set of stellar isochrones developed in previous work to estimate the metallicities of individual stars to a precision of 0.2 dex for reasonably bright stars across the ...

An Effector TaCRVP From Tuta Absoluta Oral Secretion Impairs H2O2‐Mediated Plant Defense by Targeting Tomato SlCAT2

Advanced Science, EarlyView.
The Tuta absoluta salivary effector TaCRVP subverts tomato immunity by hijacking host catalase SlCAT2. Through a sophisticated dual mechanism, TaCRVP simultaneously promotes SlCAT2 tetramerization for activation and blocks its SlAdBiL‐mediated degradation for stabilization.

MAPPING THE MILKY WAY DISK WITH STATISTICAL PHOTOMETRIC PARALLAX

, 2020
Previous attempts at picturing the Milky Way disk identified substructure called galactic wiggles. Photometric data was obtained from Sloan Digital Sky Survey (SDSS) Data Release 14 (DR14) and the Panoramic Survey Telescope and Rapid Response System ...

Signatures of a Tidally Induced Spiral Arm at the Anticenter of the Milky Way and a Kinematically Extended Anticenter Stream Using DESI Data Release 2

The Astronomical Journal
Using the Dark Energy Spectroscopic Instrument (DESI) Milky Way Survey, we examine the six-dimensional space of the anticenter region of the Milky Way stellar disk (150° < Galactic longitude < 220°) using 61,883 main-sequence turnoff stars.

Impaired Chaperone‐Mediated Autophagy Accelerates Intervertebral Disc Degeneration by Inducing MIDN Accumulation to Target TSC2 for Proteasomal Degradation

Advanced Science, EarlyView.
This graphical abstract illustrates how chaperone‐mediated autophagy (CMA) regulates intervertebral disc degeneration (IDD). Under normal homeostasis (B), CMA degrades cytoplasmic Midnolin (MIDN) to maintain proteostasis. Under inflammatory stress (A), impaired CMA leads to cytoplasmic MIDN accumulation.

The Structure, Populations, and Kinematics of the Milky Way Central and Inner Bulge with OGLE, APOGEE, and Gaia Data

The Astrophysical Journal
We present an analysis of the structure, kinematics, and chemo-dynamical properties of the Milky Way bulge using RR Lyrae stars from Optical Gravitational Lensing Experiment (OGLE), and giant stars from APOGEE and Gaia that have distances placing them in

History of star formation and chemical enrichment in the Milky Way disk

, 2002
Based on a physical treatment of the star formation law similar to that given by Efstathiou, we have improved our two-component chemical evolution model for the Milky Way disk. Two gas infall rates are compared, one exponential, one Gaussian. It is shown

Single‐Molecule Imaging of Endogenous RNA Using a Miniaturized and Circularly Permuted CRISPR‐Cas13 Degron‐Masking System CDegSR

Advanced Science, EarlyView.
CDegSR, a new tool for imaging RNA at single molecule level in living cells was developed by researchers. Background noise was eliminated by protein engineering and making it degrade when not bound to its target. This allowed individual RNA molecules to be clearly imaged and tracked.

A Wave-corrected Assessment of the Local Midplane

The Astrophysical Journal
As the number of known Galactic structures mounts thanks to the Gaia Space Telescope, it is now pertinent to study methods for disentangling structures occupying the same regions of the Milky Way. Indeed, understanding the precise form of each individual

Dust distribution in the Milky Way disk

, 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.
