Galaxy Zoo: the interplay of quenching mechanisms in the group environment★ [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2017
Does the environment of a galaxy directly influence the quenching history of a galaxy? Here we investigate the detailed morphological structures and star formation histories of a sample of SDSS group galaxies with both classifications from Galaxy Zoo 2 and NUV detections in GALEX.

Galaxy Quenching at the High Redshift Frontier: A Fundamental Test of Cosmological Models in the Early Universe with JWST-CEERS

open access: yesThe Astrophysical Journal
We present an analysis of the quenching of star formation in massive galaxies ( M _* > 10 ^9.5 M _⊙ ) within the first 0.5–3 Gyr of the Universe’s history utilizing JWST-CEERS data.

ELVES. III. Environmental Quenching by Milky Way–mass Hosts

open access: yesThe Astrophysical Journal, 2023
Isolated dwarf galaxies usually exhibit robust star formation but satellite dwarf galaxies are often devoid of young stars, even in Milky Way–mass groups.

Astragalus zhobensis, a new species of section Caprini (Fabaceae) from Zhob, northern Balochistan, Pakistan

open access: yesNordic Journal of Botany, Volume 2025, Issue 12, December 2025.
A new species Astragalus zhobensis, from Qamardin Karez, Zhob district, northern Balochistan, Pakistan is described and illustrated. The new species is morphologically similar to A. cartilagineus, but can be distinguished by strigose hairs 3–5 mm long, (not stiff 1.5−4.0 mm long hairs); stipules 5–15 mm (not 8−12 mm) long; leaflets in 4–6 pairs, (not 3–

Chloroplast genome of the critically endangered Ginger Zingiber odoriferum Blume from Java, Indonesia: characterization, comparison, and conservation insights

open access: yesNordic Journal of Botany, Volume 2025, Issue 12, December 2025.
Zingiber odoriferum (Zingiberaceae), a critically endangered ginger species endemic to Java, Indonesia, is ecologically vital yet genomically understudied. We present the first complete chloroplast (cp) genome (163 538 bp), revealing a quadripartite structure with a large single‐copy region (88 033 bp), a small single‐copy region (15 885 bp), and a ...

Evolution of Terrestrial Planetary Bodies and Implications for Habitability

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

Constraining the Quenching Mechanisms in Galaxies

open access: yes, 2022
A number of theoretical mechanisms have been invoked to explain the transformation of star forming galaxies into quenched galaxies, such as the removal of gas by active galactic nuclei- (AGN) and star formation-driven galactic outflows, and the heating of the galaxy halo and subsequent halting of gas accretion caused by virial shocks and preventative ...
