The clustering of dark matter, haloes & galaxies [PDF]

, 2008
In this thesis I study the spatial distribution of galaxies, haloes and dark matter particles using a suite of state-of-art cosmological N-body simulations of the growth structure in the Universe.

Excavating the Ruins: An Ancient z = 2.675 Galaxy Which Formed in the First 500 Myr

The Astrophysical Journal
We present the analysis of an ancient galaxy at z = 2.675, which we dub “Eridu.” Simultaneously modeling the JWST/NIRSpec G140M and G235M spectra from the SMILES program and 0.4–25 μ m Hubble Space Telescope, JWST/NIRCam, and JWST/MIRI photometry from ...

Environmental history of filament galaxies

Astronomy & Astrophysics
Galaxy properties, such as stellar mass and star formation rate, correlate with their position within the cosmic web. Although galaxy properties can be correlated with a specific environment at a certain cosmic epoch, they may have experienced different ...

The SAGA Survey. V. Modeling Satellite Systems around Milky Way–Mass Galaxies with Updated UniverseMachine

The Astrophysical Journal
Environment plays a critical role in shaping the assembly of low-mass galaxies. Here, we use the U niverse M achine (UM) galaxy–halo connection framework and Data Release 3 of the Satellites Around Galactic Analogs (SAGA) Survey to place dwarf galaxy ...

Characterising the formation and evolution of S0-galaxies (CaFES-0): Revealing the origin of the mass-size relation of S0 galaxies

Astronomy & Astrophysics
We investigated the structural evolution and formation pathways of lenticular (S0) galaxies using the Hydrangea suite of cosmological hydrodynamical simulations. Simulated galaxies reproduce the observed mass–size relation from the SAMI and MaNGA surveys,

Galaxy evolution in the post-merger regime. II -- Post-merger quenching peaks within 500 Myr of coalescence

The Open Journal of Astrophysics
Mechanisms for quenching star formation in galaxies remain hotly debated, with galaxy mergers an oft-proposed pathway. In Ellison et al. (2022) we tested this scenario by quantifying the fraction of recently and rapidly quenched post-starbursts (PSBs) in

Molecular hydrogen in galaxies [PDF]

, 1987
This study aims to understand the key role played by molecular hydrogen in the evolution of galaxies, with a view to constraining its radial distribution in the Galaxy and the CO→H(_2) conversion factor α(_20).The star formation rate is shown to be ...

PAC. V. The Roles of Mass and Environment in the Quenching of Galaxies

The Astrophysical Journal
The roles that mass and environment play in galaxy quenching are still under debate. Leveraging the Photometric objects Around Cosmic webs method, we analyze the excess surface distribution ${\bar{n}}_{2}{w}_{{\rm{p}}}({r}_{{\rm{p}}})$ of photometric ...
