One of the key open questions in extragalactic astronomy is what stops star formation in
galaxies. While it is clear that the cold gas reservoir, which fuels the formation of new stars …

The current standard model of cosmology successfully describes a variety of measurements,
but the nature of its main ingredients, dark matter and dark energy, remains unknown. is a …

We present the HI emission project within the MIGHTEE survey, currently being carried out
with the newly commissioned MeerKAT radio telescope. This is one of the first deep, blind …

Filaments are elongated structures that connect groups and clusters of galaxies and are
visually the striking feature in cosmological maps. In the literature, typically filaments are …

We develop a new Multitracer Halo Occupation Distribution (MTHOD) framework for the
galaxy distribution and apply it to the extended Baryon Oscillation Spectroscopic Survey …

ABSTRACT The Local Void is one of the nearest large voids, located at a distance of 23
Mpc. It lies largely behind the Galactic Bulge and is therefore extremely difficult to observe …

We study the spin alignment of galaxies and haloes with respect to filaments and walls of the
cosmic web, identified with DisPerSE, using the Simba simulation from z= 0− 2. Massive …

We investigate how cosmic web structures affect galaxy quenching in the IllustrisTNG
(TNG100) cosmological simulations by reconstructing the cosmic web within each snapshot …

The large-scale structure of the Universe can be understood in terms of features such as
filaments, nodes and walls, which we collectively term the cosmic web. Galaxies evolve …

It is now well established that galaxies have different morphologies, gas contents, and star
formation rates (SFR) in dense environments like galaxy clusters. The impact of …
