An Interacting Galaxy System Along a Filament in a Void

, 2013
Cosmological voids provide a unique environment for the study of galaxy formation and evolution. The galaxy population in their interior have significantly different properties than average field galaxies. As part of our Void Galaxy Survey (VGS), we have

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

Chemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

The relation between bar formation, galaxy luminosity, and environment

, 2013
We derive the bar fraction in three different environments ranging from the field to Virgo and Coma clusters, covering an unprecedentedly large range of galaxy luminosities (or, equivalently, stellar masses).

3C459: A highly asymmetric radio galaxy with a starburst

, 2003
Multifrequency radio observations of the radio galaxy 3C459 using MERLIN, VLA and the EVN, and an optical HST image using the F702W filter are presented.

Mock Observations: Morphological Analysis of Galaxies in TNG100 Simulations

The Astrophysical Journal Supplement Series
In this study, we investigate the morphology of galaxies in the TNG100 simulation by applying mock observation techniques and compare the results with the observational data from the Sloan Digital Sky Survey (SDSS).

Revisiting the Milky Way stellar long bar and the 3 kpc arm★

Astronomy & Astrophysics
Context. One of the most difficult and unexplored regions of the Milky Way is the highly extincted in-plane central region within the Galactic coordinates 10◦ ≲ |ℓ| ≲ 30◦, |b| ≲ 3◦, where we have the long-bar and 3 kpc arm with intermediate-age stellar ...

MUC1 as a Survival Effector of Radiotherapy‐Induced Epithelial Hybrid States in Basal‐Like Breast Cancer

International Journal of Cancer, EarlyView.
Basal‐like breast cancer (BLBC) is aggressive and often exhibits inherent or acquired resistance to radiotherapy (RT), a primary treatment option. RT resistance is underpinned by molecular alterations, many of which are poorly understood. Here, RT‐induced transcriptomic changes were analyzed using bulk and spatial sequencing in a BLBC mouse model and ...

The Intrinsic Flattening of Galaxy Disks

The Astrophysical Journal
Highly inclined (edge-on) disk galaxies offer the unique perspective to constrain their intrinsic flattening, c / a , where c and a are, respectively, the vertical and long radial axes of the disk measured at suitable stellar densities.

THE SHAPE OF GALAXY STRUCTURES

The Astrophysical Journal, 2009
An analysis is presented for a statistically complete sample of 547 galaxy structures with z ≤ 0.16, each containing at least 10 objects. The sample was divided according to structure richness, representing 10 richness classes, with the distribution of ellipticities differing among individual classes.

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.
