Analysis of the Functions of Cosmology Dust in Galaxy Formation

open access: yesTheoretical and Natural Science, 2023
The physical laws related to star formation in galaxies are the key to understanding the formation and evolution of galaxies. The dust in the interstellar medium has a significant effect on both the star formation and the observational properties of the ...

The evolution of galaxy formation [PDF]

open access: yesAstronomy & Geophysics, 2011
Our history of understanding galaxy formation could be traced through the development of individual ideas. A cynic might be tempted to suggest that new catchphrases are developed at a faster rate than genuine progress is made.

The GALEX Extended Mission: Surveying UV Tracers of the Hidden Side of Galaxy Evolution [PDF]

open access: yes, 2010
The Galaxy Evolution Explorer (GALEX) continues its surveys of the ultraviolet sky. GALEX surveys have supported the following galaxy evolution investigations: calibrating UV as a star formation rate tracer, using wide and deep surveys to measure star ...

Impact of Salmonella genome rearrangement on gene expression

open access: yesEvolution Letters, Volume 6, Issue 6, Page 426-437, December 2022., 2022
Abstract In addition to nucleotide variation, many bacteria also undergo changes at a much larger scale via rearrangement of their genome structure (GS) around long repeat sequences. These rearrangements result in genome fragments shifting position and/or orientation in the genome without necessarily affecting the underlying nucleotide sequence.

Galaxy peculiar velocities and evolution-bias [PDF]

open access: yes, 2007
Galaxy bias can be split into two components: a formation-bias based on the locations of galaxy creation, and an evolution-bias that details their subsequent evolution. In this letter we consider evolution-bias in the peaks model.

From Clusters to Proto-Clusters: The Infrared Perspective on Environmental Galaxy Evolution

open access: yesUniverse, 2022
Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it can control the critical process of transforming galaxies from star forming to quiescent, commonly termed “quenching”. Despite its importance, however, we still do

Targeted decrease of portal hepatic pressure gradient improves ascites control after TIPS

open access: yesHepatology, EarlyView., 2022
The river diagram demonstrates that after transjugular intrahepatic portosystemic shunt insertion (TIPS) the majority of patients without ascites and 50% of the patients with ascites detectable at ultrasound, show the best response in the long term follow‐up.

Anisotropic Satellite Galaxy Quenching: A Unique Signature of Energetic Feedback by Supermassive Black Holes?

open access: yesThe Astrophysical Journal Letters, 2023
The quenched fraction of satellite galaxies is aligned with the orientation of the halo’s central galaxy, such that on average, satellites form stars at a lower rate along the major axis of the central.

The Morphology of the Active Galactic Nucleus and its Impact on Accretion Flows and Relativistic Jets

open access: yesPhysical Sciences Forum, 2023
The G2 gas cloud motion data and the scarcity of observations on the event horizon-scale distances have challenged the comprehensiveness of the central supermassive black hole model.

Chemical Evolution of Galaxies [PDF]

open access: yes, 2000
Chemical evolution of galaxies brings together ideas on stellar evolution and nucleosynthesis with theories of galaxy formation, star formation and galaxy evolution, with all their associated uncertainties.
