On the Origin and Evolution of the Intra-Cluster Light: A Brief Review of the Most Recent Developments

open access: yesGalaxies, 2021
Not all the light in galaxy groups and clusters comes from stars that are bound to galaxies. A significant fraction of it constitutes the so-called intracluster or diffuse light (ICL), a low surface brightness component of groups/clusters generally found

The epoch of galaxy formation [PDF]

open access: yesProceedings of the National Academy of Sciences, 1997
Recent advances in technology have enabled astronomers to observe fainter, and more distant, galaxies and to study the processes of galaxy formation and evolution. Recent observations suggest that the bulk of the stars in the universe formed between z = 3 (∼1 × 10^9 years after the big bang) and the present.

Simulating galaxy formation with the IllustrisTNG model [PDF]

open access: yes, 2017
We introduce an updated physical model to simulate the formation and evolution of galaxies in cosmological, large-scale gravity+magnetohydrodynamical simulations with the moving mesh code AREPO.

Shark: introducing an open source, free, and flexible semi-analytic model of galaxy formation [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
We present a new, open source, free semi-analytic model (SAM) of galaxy formation, Shark, designed to be highly flexible and modular, allowing easy exploration of different physical processes and ways of modelling them. We introduce the philosophy behind

JWST Reveals a Population of Ultrared, Flattened Galaxies at 2 ≲ z ≲ 6 Previously Missed by HST

open access: yesThe Astrophysical Journal Letters, 2023
With just a month of data, JWST is already transforming our view of the universe, revealing and resolving starlight in unprecedented populations of galaxies.

The E-MOSAICS project: tracing galaxy formation and assembly with the age–metallicity distribution of globular clusters [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
We present 25 cosmological zoom-in simulations of Milky Way-mass galaxies in the `MOdelling Star cluster population Assembly In Cosmological Simulations within EAGLE' (E-MOSAICS) project.

EDGE: the mass–metallicity relation as a critical test of galaxy formation physics [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
We introduce the ‘Engineering Dwarfs at Galaxy Formation’s Edge’ (EDGE) project to study the cosmological formation and evolution of the smallest galaxies in the Universe.

A Lonely Giant: The Sparse Satellite Population of M94 Challenges Galaxy Formation [PDF]

open access: yesAstrophysical Journal, 2018
The dwarf satellites of “giant” Milky Way (MW)–mass galaxies are our primary probes of low-mass dark matter halos. The number and velocities of the satellite galaxies of the MW and M31 initially puzzled galaxy formation theorists, but are now reproduced ...

A Rest-frame Near-IR Study of Clumps in Galaxies at 1 < z < 2 Using JWST/NIRCam: Connection to Galaxy Bulges

open access: yesThe Astrophysical Journal, 2023
A key question in galaxy evolution has been the importance of the apparent “clumpiness” of high-redshift galaxies. Until now, this property has been primarily investigated in rest-frame UV, limiting our understanding of their relevance.
