Nature versus nurture: what regulates star formation in satellite galaxies? [PDF]
, 2018 We use our state-of-the-art Galaxy Evolution and Assembly (GAEA) semi-analytic model to study how and on which time-scales star formation is suppressed in satellite galaxies.

Star formation quenching in galaxies [PDF]
SCIENTIA SINICA Physica, Mechanica & Astronomica, 2017 The cosmic star formation rate density is peaked at $z\sim2$ and declines continuously since then, implying that the quenching of star formation has been the dominating process in galaxy evolution in the past $\sim10$ Gyr. As a result, the present day universe does not contain many star-bursting galaxies, which were the dominating population at $z\sim2$

Two Conditions for Galaxy Quenching: Compact Centres and Massive Haloes [PDF]
, 2015 We investigate the roles of two classes of quenching mechanisms for central and satellite galaxies in the SDSS ($z 10^{11.8}M_{\odot}$ are dense ($\Sigma_{\rm 1kpc} > 10^{9}~ M_{\odot} {\rm kpc}^{-2}$), suggesting compaction-related quenching maintained ...

The THESEUS Space Mission and the Infrared Telescope Calibration Unit
Astronomische Nachrichten, EarlyView.ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Death by Impact: Evidence for Merger-driven Quenching in a Collisional Ring Galaxy at Cosmic Noon
The Astrophysical JournalThe role of interactions and mergers in the rapid quenching of massive galaxies in the early Universe remains uncertain, largely due to the difficulty of directly linking mergers to quenching.

Germanium‐Based Mid‐Infrared Integrated Photonics
Laser &Photonics Reviews, EarlyView.The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

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
