The Argo Simulation: I. Quenching of Massive Galaxies at High Redshift as a Result of Cosmological Starvation [PDF]

, 2014
Observations show a prevalence of high redshift galaxies with large stellar masses and predominantly passive stellar populations. A variety of processes have been suggested that could reduce the star formation in such galaxies to observed levels ...

The SAMI Galaxy Survey: Quenching of Star Formation in Clusters I. Transition Galaxies [PDF]

Astrophysical Journal, 2019
We use integral-field spectroscopy from the SAMI Galaxy Survey to identify galaxies that show evidence of recent quenching of star formation. The galaxies exhibit strong Balmer absorption in the absence of ongoing star formation in more than 10% of their

Spatial Dynamics and Lifespan of Adult Cicadas After Fire and Logging: A Radiotracking Study

Integrative Zoology, EarlyView.
This study investigates the effects of wildfire and post‐fire salvage logging on the survival, spatial behavior, and habitat selection of Lyristes plebejus cicadas in Mediterranean pine forests. A total of 63 cicadas were captured, tagged with radio transmitters, and released in three disturbance contexts: burnt‐logged, burnt‐unlogged, and unburnt ...

How is star formation quenched in massive galaxies? [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
The bimodality in observed present-day galaxy colours has long been a challenge for hierarchical galaxy formation models, as it requires some physical process to quench (and keep quenched) star formation in massive galaxies. Here we examine phenomenological models of quenching by post-processing the star formation histories of galaxies from ...

In silico, in vitro and ex vivo characterization of cystic fibrosis transmembrane conductance regulator pathogenic variants localized in the fourth intracellular loop and their rescue by modulators

British Journal of Pharmacology, EarlyView.
Background and Purpose Cystic fibrosis (CF) is due to loss‐of‐function variants of the CF transmembrane conductance regulator (CFTR) channel. The most effective treatment for people with CF carrying the F508del mutation is the triple combination of elexacaftor–tezacaftor–ivacaftor (ETI).

CLEAR II: Evidence for Early Formation of the Most Compact Quiescent Galaxies at High Redshift

, 2020
The origin of the correlations between mass, morphology, quenched fraction, and formation history in galaxies is difficult to define, primarily due to the uncertainties in galaxy star-formation histories.

Evidence for Inside-out Galaxy Growth and Quenching of a z ∼ 2 Compact Galaxy From High-resolution Molecular Gas Imaging [PDF]

Astrophysical Journal, 2019
We present high spatial resolution imaging of the CO(1–0) line from the Karl G. Jansky Very Large Array of COSMOS 27289, a massive, compact star-forming galaxy (SFG) at z = 2.234.

Star formation quenching in galaxies [PDF]

SCIENTIA SINICA Physica, Mechanica & Astronomica, 2017
The cosmic star formation rate density is peaked at $z\sim2$ and declines continuously since then, implying that the quenching of star formation has been the dominating process in galaxy evolution in the past $\sim10$ Gyr. As a result, the present day universe does not contain many star-bursting galaxies, which were the dominating population at $z\sim2$

CTCF Is Essential for the Development and Maintenance of CALM‐AF10‐Induced Leukemia

Cancer Science, EarlyView.
CTCF regulates TGM2 gene expression by modulating key histone modifications, including increased acetylation of H3K27 (H3K27ac) and trimethylation of H3K4 (H3K4me3), along with decreased trimethylation of H3K27 (H3K27me3). These epigenetic changes are critical for maintaining the stem‐like properties of CALM‐AF10‐induced AML. Pharmacological inhibition

Gas Loss by Ram Pressure Stripping and Internal Feedback From Low Mass Milky Way Satellites

, 2016
The evolution of dwarf satellites of the Milky Way is affected by the combination of ram pressure and tidal stripping, and internal feedback from massive stars.
