Galaxy Disks [PDF]

Annual Review of Astronomy and Astrophysics, 2011
The disks of disk galaxies contain a substantial fraction of their baryonic matter and angular momentum, and much of the evolutionary activity in these galaxies, such as the formation of stars, spiral arms, bars and rings, and the various forms of secular evolution, takes place in their disks. The formation and evolution of galactic disks are therefore

Scintillation Response of 0D Cs3Cu2I5 Thin Layers to Light‐ and Heavy‐Ion Irradiation

Advanced Photonics Research, EarlyView.
Driven by increasing interest in uncovering the remarkable photoluminescence quantum yield of Cs3Cu2I5, polycrystalline thin layers are synthesized to investigate its radioluminescence response to energetic ions. Its spectroscopic capability is assessed in a wide range of ion mass and internal excitation processes are explored.

Galaxy And Mass Assembly (GAMA) blended spectra catalogue: strong galaxy-galaxy lens and occulting galaxy pair candidates [PDF]

, 2015
We present the catalogue of blended galaxy spectra from the Galaxy And Mass Assembly (GAMA) survey. These are cases where light from two galaxies are significantly detected in a single GAMA fibre.

Exercise without Weight Loss Prevents Seasonal Decline in Vitamin D Metabolites: The VitaDEx Randomized Controlled Trial

Advanced Science, EarlyView.
In people with overweight or obesity, regular exercise even without weight loss or vitamin D supplementation completely prevents the usual winter decline in the vitamin D metabolite that maintains health at a cellular level, 1,25(OH)2D3, and ameliorates the decline in the vitamin D status marker 25(OH)D.

A galaxy of folds [PDF]

Protein Science, 2009
AbstractMany protein classification systems capture homologous relationships by grouping domains into families and superfamilies on the basis of sequence similarity. Superfamilies with similar 3D structures are further grouped into folds. In the absence of discernable sequence similarity, these structural similarities were long thought to have ...

AhR‐Dependent Induction of β‐Defensin 1 in Colonic Epithelial Cells Regulates Cross‐Talk between Gut Microbiota and Immune Response Leading to Attenuation of Colitis

Advanced Science, EarlyView.
This study identifies a key signaling pathway involving the environmental sensor AhR and antimicrobial peptides, such as BD‐1, in the regulation of intestinal homeostasis. It highlights the role of BD‐1 in regulating gut microbiota and the intestinal immune response.

Redshifts of the Gravitational Lenses MG0414+0534 and MG0751+2716 [PDF]

, 1998
We report redshifts in two gravitational lens systems, MG0414+0534 and MG0751+2716. The lens galaxy in MG0414+0534 lies at z_l=0.9584+/-0.0002. The luminosity and extreme red color of the lens are then typical of a passively evolving, early-type, ~2L ...

“GALAXY,” DEFINED [PDF]

The Astronomical Journal, 2012
A growing number of low luminosity and low surface brightness astronomical objects challenge traditional notions of both galaxies and star clusters. To address this, we propose a definition of galaxy independent of the cold dark matter model of the universe: A galaxy is a gravitationally bound set of stars whose properties cannot be explained by a ...

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa

Advanced Science, EarlyView.
Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...
