In this paper, we present photometric redshifts for 2.7 million galaxies in the XMM-LSS and
COSMOS fields, both with rich optical and near-infrared data from VISTA and
HyperSuprimeCam. Both template fitting (using galaxy and active galactic nuclei templates
within LePhare) and machine learning (using gpz) methods are run on the aperture
photometry of sources selected in the K s-band. The resulting predictions are then combined
using a Hierarchical Bayesian model, to produce consensus photometric redshift point�…

We study the 3D axis of rotation (3D spin) of 77 H i galaxies from the MIGHTEE-H i Early
Science observations, and its relation to the filaments of the cosmic web. For this H i-
selected sample, the alignment between the spin axis and the closest filament (| cos ψ|) is
higher for galaxies closer to the filaments, with〈| cos ψ|〉= 0.66�0.04 for galaxies< 5 Mpc
from their closest filament compared to〈| cos ψ|〉= 0.37�0.08 for galaxies at 5< d< 10 Mpc.
We find that galaxies with a low H i-to-stellar mass ratio (log10 (MH i/M⋆)< 0.11) are more�…
