Galaxy evolution in protoclusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We investigate galaxy evolution in protoclusters using a semi-analytic model applied to the Millennium Simulation, scaled to a Planck cosmology. We show that the model reproduces the observed behaviour of the star formation history (SFH) both in ...

AGN EVOLUTION FROM A GALAXY EVOLUTION VIEWPOINT [PDF]
The Astrophysical Journal, 2014 We explore the connections between the evolving galaxy and active galactic nucleus (AGN) populations. We present a simple phenomenological model that links the evolving galaxy mass function and the evolving quasar luminosity function, which makes ...

From Clusters to Proto-Clusters: The Infrared Perspective on Environmental Galaxy Evolution [PDF]
Universe, 2022 Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it can control the critical process of transforming galaxies from star forming to quiescent, commonly termed “quenching”. Despite its importance, however, we still do

The evolution of the galaxy UV luminosity function at redshifts z ≃ 8 – 15 from deep JWST and ground-based near-infrared imaging [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We reduce and analyse the available JWST ERO and ERS NIRCam imaging (SMACS0723, GLASS, CEERS) in combination with the latest deep ground-based near-infrared imaging in the COSMOS field (provided by UltraVISTA DR5) to produce a new measurement of the ...

Evolution Through the Post-starburst Phase: Using Post-starburst Galaxies as Laboratories for Understanding the Processes that Drive Galaxy Evolution [PDF]
Publications of the Astronomical Society of the Pacific, 2021 Post-starburst (or “E+A”) galaxies trace the fastest and most dramatic processes in galaxy evolution. Recent work studying the evolution of galaxies through this phase has revealed insights on how galaxies undergo structural and stellar population ...

Voronoi volume function: a new probe of cosmology and galaxy evolution [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We study the Voronoi volume function (VVF) – the distribution of cell volumes (or inverse local number density) in the Voronoi tessellation of any set of cosmological tracers (galaxies/haloes).

Understanding Galaxy Evolution Through Emission Lines [PDF]
Annual Review of Astronomy and Astrophysics, 2019 We review the use of emission lines for understanding galaxy evolution, focusing on excitation source, metallicity, ionization parameter, ISM pressure, and electron density.
