THE DEPENDENCE OF QUENCHING UPON THE INNER STRUCTURE OF GALAXIES AT 0.5 ⩽ z < 0.8 IN THE DEEP2/AEGIS SURVEY [PDF]

, 2012
The shutdown of star formation in galaxies is generally termed “quenching.” Quenching may occur through a variety of processes, e.g., active galactic nucleus (AGN) feedback, stellar feedback, or the shock heating of gas in the dark matter halo.

Chlorinated Paracyclophanes: Composition Analysis and Direct Metal‐Free Alkylation with n‐BuLi

European Journal of Organic Chemistry, EarlyView.
A transition‐metal‐free alkylation of pseudo‐para dichloro[2.2]paracyclophane (Cl2‐PCP) is reported, utilizing the purified pseudo‐para isomer and n‐butyllithium (BuLi). Optimization with the chelating agent TMEDA and refluxing n‐heptane significantly boosted selectivity and reaction rate, providing the dialkylated product in 22% isolated yield.

Structure and Evolution of Regular Galaxies

, 2021
This is English translation of the Thesis, originally written in Russian and remained unpublished. The Thesis was an attempt to combine data from three previously independent areas: the structure and kinematics of stellar populations of the Galaxy, photometric and dynamical models of galaxies, and models of the dynamical and physical evolution of ...

The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: measuring structure growth using passive galaxies [PDF]

, 2012
We explore the benefits of using a passively evolving population of galaxies to measure the evolution of the rate of structure growth between z = 0.25 and 0.65 by combining data from the Sloan Digital Sky Survey (SDSS) I/II and SDSS-III surveys.

THE STELLAR MASS STRUCTURE OF MASSIVE GALAXIES FROM z = 0 TO z = 2.5: SURFACE DENSITY PROFILES AND HALF-MASS RADII [PDF]

, 2012
We present stellar mass surface density profiles of a mass-selected sample of 177 galaxies at 0.5 < z < 2.5, obtained using very deep Hubble Space Telescope optical and near-infrared data over the GOODS-South field, including recent CANDELS data ...

Akkermansia muciniphila enhances chicken resistance to infectious bronchitis virus by boosting GABA synthesis and suppressing the NF‐κB inflammatory pathway

iMetaOmics, EarlyView.
Infectious bronchitis virus (IBV) represents a major threat to poultry production, with current control strategies offering limited protection. In this study, we demonstrate gut microbiome is a critical determinant of IBV resistance using fecal microbiota transplantation.
