An Extremely Massive Quiescent Galaxy at z = 3.493: Evidence of Insufficiently Rapid Quenching Mechanisms in Theoretical Models [PDF]

Astrophysical Journal, 2019
We present spectra of the most massive quiescent galaxy yet spectroscopically confirmed at z > 3, verified via the detection of Balmer absorption features in the H- and K-bands of Keck/MOSFIRE.

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

Nordic Journal of Botany, EarlyView.
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 ...

Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

People and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

Stellar Velocity Dispersion of a Massive Quenching Galaxy at z = 4.01 [PDF]

Astrophysical Journal, 2019
We present the first stellar velocity dispersion measurement of a massive quenching galaxy at z = 4. The galaxy is first identified as a massive z ≥ 4 galaxy with suppressed star formation from photometric redshifts based on deep multiband data. A follow-

The SAGA Survey. IV. The Star Formation Properties of 101 Satellite Systems around Milky Way–mass Galaxies

The Astrophysical Journal
We present the star-forming properties of 378 satellite galaxies around 101 Milky Way analogs in the Satellites Around Galactic Analogs (SAGA) Survey, focusing on the environmental processes that suppress or quench star formation.

CANDELS Sheds Light on the Environmental Quenching of Low-mass Galaxies [PDF]

, 2017
We investigate the environmental quenching of galaxies, especially those with stellar masses (M*)$10^{10.5} M_\odot$) within a redshift range. At a given redshift and M*, the environmental quenching effect is considered to be observed if the $d_{proj ...

Quenching as a Contest between Galaxy Halos and Their Central Black Holes [PDF]

Astrophysical Journal, 2019
Existing models of galaxy formation have not yet explained striking correlations between structure and star formation activity in galaxies, notably the sloped and moving boundaries that divide star-forming from quenched galaxies in key structural ...

Soil community structure across native and exotic forests is shaped by edaphoclimatic conditions and eukaryotic biomarkers

Journal of Applied Ecology, EarlyView.
Our results point to the importance of taking management decisions for these forests considering regional conditions as well as forest type. The provided list of soil keystone taxa should be taken into account in future research and soil monitoring, which is essential for sustainable management of land.

Revealing the Impact of Critical Stellar Central Density on Galaxy Quenching through Cosmic Time

The Astrophysical Journal
In a previous work, we investigated the structural and environmental dependence on quenching in the nearby universe. In this work, we extend our investigations to higher redshifts by combining galaxies from the Sloan Digital Sky Survey and The FourStar ...

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

The 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.
