Towards a physical picture of star formation quenching: The photometric properties of recently quenched galaxies in the sloan digital sky survey

open access: yes, 2013
We select a sample of young passive galaxies from the Sloan Digital Sky Survey data release 7 in order to study the processes that quench star formation in the local universe.

Supramolecular Aggregates of Amino Acid‐Functionalized 1,8‐Naphthalimides for Chiral Recognition

open access: yesChemistry–Methods, Volume 6, Issue 7, July 2026.
We synthesized three self‐assembling, amino acid‐functionalized 1,8‐naphthalimides. We studied their aggregation in solution and demonstrated their chiral recognition ability by fluorescence and resonance light scattering measurements. Notably, these fluorescent probes maintain their chiral recognition ability when incorporated in solid supports like ...

Massive Quiescent Disk Galaxies at 0.5 ≤ z ≤ 1 in CANDELS: Color Gradients and Likely Origin

open access: yesThe Astrophysical Journal
A rare population of massive disk-dominated quiescent galaxies has recently drawn much attention, which intrudes the red sequence (RS) population without destroying the underlying stellar disks.

Euclid Quick Data Release (Q1). A probabilistic classification of quenched galaxies

open access: yes
International audienceInvestigating the drivers of the quenching of star formation in galaxies is key to understanding their evolution. The Euclid mission will provide rich spatial and spectral data from optical to infrared wavelengths for millions of ...

Out There No One Has a Right to Die

open access: yesBioethics, Volume 40, Issue 6, Page 565-572, July 2026.
ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...

Dissecting the Mass Quenching in TNG50: Galaxy Size Determines the Quenching Mode

open access: yesThe Astrophysical Journal
Abstract The diminishing of star formation is accompanied by size differentiating, as quiescent galaxies are more compact than star-forming galaxies (SFGs) at fixed stellar mass. In order to understand how galaxy quenching is related to galaxy sizes, we performed a demographic study of 46 massive quiescent central

Automation and Augmentation in Theological Perspective

open access: yesModern Theology, Volume 42, Issue 3, Page 612-628, July 2026.
Abstract AI enables forms of automation that threaten unemployment and deskilling, eliminating important opportunities for the development of virtue. The concomitant loss of virtue and meaningful employment makes it a theological problem from the perspective of Catholic social teaching and theological anthropology.

Comparative Evaluation of Smartphone‐Based Fundus Imaging Systems in Dogs and Cats

open access: yesVeterinary Ophthalmology, Volume 29, Issue 4, July 2026.
ABSTRACT Objective To compare the feasibility, image quality, acquisition time, and evaluator preference of four smartphone‐based fundus imaging (SBFI) systems in dogs and cats using a handheld fundus camera as a reference device. Animals Studied Twenty client‐owned animals, including 10 dogs and 10 cats.
