The enhancement of rapidly quenched galaxies in distant clusters at
0.5
, 2018 We investigate the relationship between environment and galaxy evolution in the redshift range $0.5 < z < 1.0$. Galaxy overdensities are selected using a Friends-of-Friends algorithm, applied to deep photometric data in the Ultra-Deep Survey (UDS) field. A study of the resulting stellar mass functions reveals clear differences between cluster and field

Rethinking the relation between human and nature: Insights from science fiction
Business and Society Review, Volume 130, Issue S1, Page 183-197, Spring 2025.Abstract Facing the accumulation of data that suggest near‐future dramatic changes in our way of life, current visions of transition are anchored in an incremental paradigm that excludes radical change. Using science fiction literature and cinema, this article aims to build such drastic change hypotheses and explore the political–ecological features of

The role of DNA content in shaping chromatin architecture and gene expression
The Plant Journal, Volume 121, Issue 6, March 2025.SUMMARY Whole‐genome duplication is an evolutionary force that drives speciation in all living kingdoms and is notably prevalent in plants. The evolutionary history of plants involved at least two genomic duplications that significantly expanded the plant morphology and physiology spectrum. Many important crops are polyploids, showing valuable features

The Astrophysical JournalWe 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

The Astrophysical JournalThe formation pathways of lenticular galaxies (S0s) in field environments remain a matter of debate. We utilize the cosmological hydrodynamic simulation, NewHorizon , to investigate the issue. We select two massive star formation quenched S0s as our main

A Massive Quiescent Galaxy in a Group Environment at z = 4.53
The Astrophysical JournalWe 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.

On the Origin of Quenched but Gas-rich Regions at Kiloparsec Scales in Nearby Galaxies
The Astrophysical JournalWe use resolved spectroscopy from MaNGA to investigate the significance of both local and global properties of galaxies to the cessation of star formation at kpc scales.

Hedgehog: An Isolated Quiescent Dwarf Galaxy at 2.4 Mpc
The Astrophysical Journal LettersIt is well known that almost all isolated dwarf galaxies are actively forming stars. We report the discovery of dw1322m2053 (nicknamed Hedgehog), an isolated quiescent dwarf galaxy at a distance of 2.40 ± 0.15 Mpc with a stellar mass of M _⋆ ≈ 10 ^5.8 M ...
