PhaseTracer2: from the effective potential to gravitational waves
In recent years, the prospect of detecting gravitational waves sourced from a strongly first-order cosmological phase transition has emerged as one of the most exciting frontiers of gravitational wave astronomy.

Did the Universe Reheat After Recombination?
Here, we consider cosmological models with post-recombination reheating (PRR), in which the CMB monopole temperature abruptly increases due to energy injection after last scattering.

GetDist: a Python package for analysing Monte Carlo samples
Monte Carlo techniques, including MCMC and other methods, are widely used and generate sets of samples from a parameter space of interest that can be used to infer or plot quantities of interest.

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.

An 85-s X-ray quasi-periodicity after a stellar tidal disruption by a candidate intermediate-mass black hole
It is still in dispute the existence of intermediate-mass black holes (IMBHs) with a mass of ~10^3-10^5 solar masses (Msun), which are the missing link between stellar-mass black holes (5-50 Msun) and supermassive black holes (10^6-10^10 Msun).

Probing light relics through cosmic dawn
We explore the prospects of upcoming 21-cm surveys of cosmic dawn ($12\lesssim \! z\lesssim\! 30$) to provide cosmological information on top of upcoming cosmic microwave background (CMB) and large-scale structure surveys, such as CMB-S4, Simons Observatory (SO) and DESI.
