Future prospects in observational galaxy evolution: towards increased resolution

, 2012
Future prospects in observational galaxy evolution are reviewed from a personal perspective. New insights will especially come from high-redshift integral field kinematic data and similar low-redshift observations in very large and definitive surveys. We

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.

Scalable N-body code for the modelling of early-type galaxies

, 2007
Early-type galaxies exhibit a wealth of photometric and dynamical structures. These signatures are fossil records of their formation and evolution processes.

Integral field spectroscopy of four lensed quasars: analysis of their neighborhood and evidence for microlensing [PDF]

, 2008
CONTEXT: Gravitationally lensed quasars constitute an independent tool to derive H0 through time-delays; they offer as well the opportunity to study the mass distribution and interstellar medium of their lensing galaxies and, through microlensing they ...

Ginseng polysaccharides prevent mastitis through Lactobacillus murinus‐derived deoxycholic acid and TGR5 signaling

iMetaOmics, EarlyView.
Prebiotic Ginseng polysaccharides (GP) alleviate mastitis through selective enrichment of gut L. murinus, which elevates its anti‐inflammatory metabolite deoxycholic acid (DCA). Circulating DCA engages mammary epithelial TGR5 receptors, triggering the cAMP–PKA pathway to suppress NF‐κB/NLRP3‐mediated inflammation.

Are High-Σ1 Massive Blue Spiral Galaxies Rejuvenated Systems?

The Astrophysical Journal
Quiescent galaxies generally possess denser cores than star-forming galaxies with similar mass. As a measurement of the core density, the central stellar mass surface density within a radius of 1 kpc (Σ _1 ) was thus suggested to be closely related to ...

Exploring the gravitationally lensed system HE 1104-1805: Near-IR Spectroscopy [PDF]

, 2000
(Abridged) A new technique for the spatial deconvolution of spectra is applied to near-IR (0.95 - 2.50 micron) NTT/SOFI spectra of the lensed, radio-quiet quasar HE 1104-1805. The continuum of the lensing galaxy is revealed between 1.5 and 2.5 micron. It
