NEWLY QUENCHED GALAXIES AS THE CAUSE FOR THE APPARENT EVOLUTION IN AVERAGE SIZE OF THE POPULATION [PDF]
, 2013 We use the large COSMOS sample of galaxies to study in an internally self-consistent way the change in the number densities of quenched early-type galaxies (Q-ETGs) of a given size over the redshift interval 0.2 < z < 1 in order to study the claimed size

ALMA reveals large molecular gas reservoirs in recently-quenched galaxies
Proceedings of the International Astronomical Union, 2019 We still do not understand the physical mechanisms that are responsible for suppressing star formation in galaxies. Observations of post-starburst galaxies, whose spectra indicate that an intense period of star formation was followed by rapid quenching ...

Towards a physical picture of star formation quenching: the photometric properties of recently quenched galaxies in the Sloan Digital Sky Survey [PDF]
, 2012 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.

The Evolving Effect of Cosmic Web Environment on Galaxy Quenching
The Astrophysical Journal, 2023 We investigate how cosmic web structures affect galaxy quenching in the IllustrisTNG (TNG100) cosmological simulations by reconstructing the cosmic web within each snapshot using the D is P er SE framework.

Constraints on Quenching of Z ≲ 2 Massive Galaxies from the Evolution of the Average Sizes of Star-forming and Quenched Populations in COSMOS [PDF]
, 2017 We use >9400 quiescent and star-forming galaxies at z ≲ 2 in COSMOS/UltraVISTA to study the average size evolution of these systems, with focus on the rare ultra-massive population at . The large 2 square degree survey area delivers a sample of ∼400 such

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Galaxy quenching in various environments
, 2023 Already early studies of the morphology-density relation of galaxies showed that early-type galaxies lie in the centres of rich clusters, and in small groups in filaments between clusters, where they are located closer to filament axis than late-type galaxies. This means that galaxies are indeed pre-processed in groups. In our present study we searched

The Morphological Transformation and the Quenching of Galaxies [PDF]
The Astrophysical Journal, 2019 Abstract We study the morphological transformation from late types to early types and the quenching of galaxies with the seventh Data Release (DR7) of the Sloan Digital Sky Survey. Both early-type galaxies and late-type galaxies are found to have bimodal distributions on the star formation rate versus stellar mass diagram (lg SFR–lg M
