Unravelling Taxonomic Complexity in Elusive Cetaceans: Mitogenome Insights into Evolutionary History and Cryptic Diversity of Bryde's Whales

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The Bryde's whale is one of the least understood baleen whale species globally, limiting accuracy of regional and global conservation assessment. This study shows the occurrence of unique genetic lineages and evolutionary histories among Bryde's whale populations.

PAC. V. The Roles of Mass and Environment in the Quenching of Galaxies

The Astrophysical Journal
The roles that mass and environment play in galaxy quenching are still under debate. Leveraging the Photometric objects Around Cosmic webs method, we analyze the excess surface distribution ${\bar{n}}_{2}{w}_{{\rm{p}}}({r}_{{\rm{p}}})$ of photometric ...

Clues to inside-out quenching in quiescent galaxies at 1.2 ≲ z ≲ 2.2: Age, Fe-, and Mg-abundance gradients from JWST-SUSPENSE

Astronomy & Astrophysics
Spatially resolved stellar populations of massive quiescent galaxies at cosmic noon provide powerful insights into star-formation quenching and stellar mass assembly mechanisms.

The Heavy Metal Survey: The Evolution of Stellar Metallicities, Abundance Ratios, and Ages of Massive Quiescent Galaxies since z ∼ 2

The Astrophysical Journal
We present the elemental abundances and ages of 19 massive quiescent galaxies at z ∼ 1.4 and z ∼ 2.1 from the Keck Heavy Metal Survey. The ultradeep LRIS and MOSFIRE spectra were modeled using a full-spectrum stellar population fitting code with variable

SDSS-C4 3028: the Nearest Blue Galaxy Cluster Devoid of an Intracluster Medium

The Open Journal of Astrophysics
SDSS-C4 3028 is a galaxy cluster at $z=0.061$, notable for its unusually high fraction of star-forming galaxies with 19 star-forming and 11 quiescent spectroscopically-confirmed member galaxies. From Subaru/HSC imaging, we derived a weak lensing mass of $

Widespread Rapid Quenching at Cosmic Noon Revealed by JWST Deep Spectroscopy

The Astrophysical Journal
Massive quiescent galaxies in the young Universe are expected to be quenched rapidly, but it is unclear whether they all experience starbursts before quenching and what physical mechanism drives rapid quenching. We study 14 massive quiescent galaxies ( $\

A Massive Quiescent Galaxy in a Group Environment at z = 4.53

The Astrophysical Journal
We report on the spectroscopic confirmation of a massive quiescent galaxy at z _spec = 4.53 in the COSMOS field. The object was first identified as a galaxy with suppressed star formation at z _phot ∼ 4.65 from the COSMOS2020 catalog.
