Abstract: The dynamical modelling of integral field unit (IFU) stellar kinematics is a powerful tool to unveil the dynamical structure and mass build-up of galaxies in the local Universe, while gravitational lensing is nature’s cosmic telescope… read more here.

DOI: 10.1093/mnras/staa259
Abstract: We study the physical mechanisms that cause the offset between low-redshift and high-redshift galaxies on the [OIII]/H$\beta$ versus [NII]/H$\alpha$ ``Baldwin, Phillips & Terlevich'' (BPT) diagram using a sample of local analogues of high-redshift galaxies. These… read more here.

DOI: 10.1093/mnras/stad1264
Abstract: Lyman α (Lyα) is now routinely used as a tool for studying high-redshift galaxies and its resonant nature means it can trace neutral hydrogen around star-forming galaxies. Integral field spectrograph measurements of high-redshift Lyα emitters… read more here.

DOI: 10.1093/mnras/sty3062
Abstract: I report detections of four new HI 21-cm absorbers associated with sources at intermediate redshifts, 0.7 1. Three detections show strong blueshifted features, indicating cold gas outflows. These three sources also tentatively show excess [O… read more here.

DOI: 10.1093/mnras/stz1810
Abstract: We study the sizes, angular momenta, and morphologies of high-redshift galaxies, using an update of the meraxes semi-analytic galaxy evolution model. Our model successfully reproduces a range of observations from redshifts z = 0–10. We find that the… read more here.
