Lyα emitters in a cosmological volume II: the impact of the intergalactic medium (2019)
Journal Article

In the near future galaxy surveys will target Lyman alpha emitting galaxies (LAEs) to unveil the nature of dark energy. It has been suggested that the observability of LAEs is coupled to the large scale properties of the intergalactic medium. Such co...

The evolution of the UV-to-mm extragalactic background light: evidence for a top-heavy initial mass function? (2019)
Journal Article

We present predictions for the UV-to-mm extragalactic background light (EBL) from a recent version of the GALFORM semi-analytical model of galaxy formation which invokes a top-heavy stellar initial mass function (IMF) for galaxies undergoing dynamica...

The evolution of SMBH spin and AGN luminosities for z < 6 within a semi-analytic model of galaxy formation (2019)
Journal Article

Understanding how Active Galactic Nuclei (AGN) evolve through cosmic time allows us to probe the physical processes that control their evolution. We use an updated model for the evolution of masses and spins of supermassive black holes (SMBHs), coupl...

Lyα emitters in a cosmological volume I: the impact of radiative transfer (2019)
Journal Article

Lyman-α emitters (LAEs) are a promising target to probe the large scale structure of the Universe at high redshifts, z ≳ 2. However, their detection is sensitive to radiative transfer effects that depend on local astrophysical conditions. Thus, model...

A comparison between semi-analytical gas cooling models and cosmological hydrodynamical simulations (2019)
Journal Article

We compare the mass cooling rates and cumulative cooled-down masses predicted by several semi-analytical (SA) cooling models with cosmological hydrodynamical simulations performed using the AREPO code (ignoring processes such as feedback and chemical...

The first Super Massive Black Holes: indications from models for future observations (2019)
Journal Article

We present an exploration of the expected detection of the earliest Active Galactic Nuclei (AGN) in the Universe from state-of-art galaxy formation and evolution semi-analytic models and hydro-dynamical simulations. We estimate the number and radiati... Read More about The first Super Massive Black Holes: indications from models for future observations.
