The Milky Way has no thick disk

, 2011
Different stellar sub-populations of the Milky Way's stellar disk are known to have different vertical scale heights, their thickness increasing with age. Using SEGUE spectroscopic survey data, we have recently shown that mono-abundance sub-populations, defined in the [α/Fe]-[Fe/H] space, are well described by single exponential spatial-density ...

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 ...

The Orbital Eccentricities of Planets in the Kinematic Thin and Thick Galactic Disks

The Astronomical Journal
The orbital eccentricity distribution of exoplanets is shaped by a combination of dynamical processes, reflecting both formation conditions and long-term evolution.

Matching TGF‐β1 Activation With Stress‐Responsive Charge‐Reversal Hydrogel Microspheres for the Treatment of Osteoarthritis

Exploration, EarlyView.
Based on the interaction between the weakly cross‐linked disulfide bonds that break under stress and charge‐reversal messenger molecules, we herein achieved nanoparticle charge reversal under stress and constructed a stress‐responsive charge‐reversal hydrogel microsphere system using microfluidic technology.

Microlensing Events in Five Years of Photometry from the Zwicky Transient Facility

The Astrophysical Journal
Microlensing has a unique advantage for detecting dark objects in the Milky Way, such as free-floating planets, neutron stars, and stellar-mass black holes.

In Vitro Characterization of Technological and Health‐Promoting Properties of Enterocin Producing Lactic Acid Bacteria From Camel Milk and Its Suitability as a Dairy Starter

Food Chemistry International, EarlyView.
Enterocin‐producing Enterococcus faecium RSCUDR7 from camel milk exhibited strong probiotic and antimicrobial properties, along with stability in skim milk. Its suitability as a safe and effective dairy starter highlights its potential for developing functional probiotic dairy products.

Disk origin of the Milky Way bulge: the necessity of the thick disk

, 2019
In the Milky Way bulge, metal-rich stars form a strong bar and are more peanut-shaped than metal-poor stars. It has recently been claimed that this behavior is driven by the initial (i.e., before bar formation) in-plane radial velocity dispersion of ...

Multifunctional Properties of Wintergreen (Gaultheria procumbens) Essential Oil: Antimicrobial, Antibiofilm, and Insecticidal Effects

Flavour and Fragrance Journal, EarlyView.
Unveiling the potential of Wintergreen (Gaultheria procumbens) essential oil. ABSTRACT This study investigated the antimicrobial, antibiofilm, and insecticidal properties of wintergreen (Gaultheria procumbens L.) essential oil (GPEO). The EO was chemically characterized by GC–MS, confirming methyl salicylate as the predominant compound (99.3%).
