Cosmological analyses of Lyman- forest clustering rely on either one-dimensional correlations along individual sightlines or three-dimensional correlations between different sig…
MIGHTEE: The Host-Galaxy Associated Catalogue of the Radio Sources in MIGHTEE Continuum Data Release 1
C. L. Hale, J. Hamlett, I. H. Whittam +34
Radio continuum surveys provide samples of active galactic nuclei (AGN) and star forming galaxies (SFGs) to high redshifts, free of biases due to dust obscuration. However, radio d…
An HI+radio continuum study of local cluster galaxies: Intercepting the early stages of environmental processing with MeerKAT
Alessandro Ignesti, Paolo Serra, Alessandro Bianchetti +14
The evolution of galaxies in clusters is driven by their interaction with the environment, which deeply affects and alters the properties of the multi-phase interstellar medium. He…
Cosmic variance or galaxy bias? Disentangling finite-volume and galaxy formation effects in cosmological analysis

We present a comparative overview of state-of-the-art methods for modelling the distribution of neutral hydrogen (HI) in the post-reionization Universe, developed in preparation fo…
The baryonic Tully-Fisher relation as an independent direct probe of cosmology and of the nature of dark matter
Francesco Sinigaglia
The baryonic Tully-Fisher relation (BTFR), a well-established galaxy scaling relation linking the dynamical mass of rotation-supported galaxies through their maximum circular veloc…
Integral field spectroscopy with no IFUs: combining wide-field rotational slitless spectroscopy with tomographic reconstruction
Jerry Jun-Yan Zhang, Francesco Sinigaglia
Among spectroscopic techniques, Integral Field Spectroscopy (IFS) is regarded as one of the most versatile and powerful, but it is limited by small FoVs, complex designs, and high…
