The buildup of galaxies and their spheroids: the contributions of mergers, disc instabilities and star formation
Disc instabilities and their associated starbursts dominate for intermediate-mass spheroids ($10^{8. 5}<M_\mathrm{*, sph}<10^{11}$ M$_\odot$) at $z=0$.

Cosmological Constraints on 4-Dimensional Einstein-Gauss-Bonnet Gravity
4-Dimensional Einstein-Gauss-Bonnet (4DEGB) gravity has garnered significant attention in the last few years as a phenomenological competitor to general relativity.

Modelling DSA, FAST and CRAFT surveys in a z-DM analysis and constraining a minimum FRB energy
This work follows from previous redshift-dispersion measure ($z$-DM) analyses in which we model instrumental biases and simultaneously fit population parameters and cosmological parameters to the observed population of FRBs.

The Athena++ Adaptive Mesh Refinement Framework: Multigrid Solvers for Self-Gravity
We describe the implementation of multigrid solvers in the Athena++ adaptive mesh refinement (AMR) framework and their application to the solution of the Poisson equation for self-gravity.

PyAutoLens: Open-Source Strong Gravitational Lensing
Strong gravitational lensing, which can make a background source galaxy appears multiple times due to its light rays being deflected by the mass of one or more foreground lens galaxies, provides astronomers with a powerful tool to study dark matter, cosmology and the most distant Universe.

Mapping stellar surfaces III: An Efficient, Scalable, and Open-Source Doppler Imaging Model
It is also critical to the detection and characterization of extrasolar planets, in particular those targeted in extreme precision radial velocity (EPRV) searches, which must contend with stellar variability that is often orders of magnitude stronger than the planetary signal.
