Exact CMB B-mode power spectrum from anisotropic cosmic birefringence
We also constrain the amplitude of the angular power spectrum of the scale-invariant anisotropic cosmic birefringence using the SPTpol $B$-mode power spectrum.

A Self-Consistent Treatment of the Line-Driving Radiation Force for Active Galactic Nuclei Outflows: New Prescriptions for Simulations
Flows driven by photons have been studied for almost a century, and a quantitative description of the radiative forces on atoms and ions is important for understanding a wide variety of systems with outflows and accretion disks, such as active galactic nuclei.

The formation of transiting circumplanetary debris discs from the disruption of satellite systems during planet-planet scattering
The debris trails arising from these events are often tilted at tens of degrees to the planetary orbit, consistent with the inclinations of the observed discs.

Stage-IV Cosmic Shear with Modified Gravity and Model-independent Screening
We forecast constraints on minimal model-independent parametrisations of several Modified Gravity theories using mock Stage-IV cosmic shear data.

Determining the time before or after a galaxy merger event
These data were then used to train a residual network (ResNet50), a Swin Transformer (Swin), a convolutional neural network (CNN), and an autoencoder (using a single latent neuron) to reproduce the merger time.

Wong et al. introduced Jim arXiv:2302. 05333, a parameter estimation pipeline that combines relative binning and jax features such as hardware acceleration and automatic differentiation into a normalizing flow-enhanced sampler for gravitational waves from binary black hole (BBH) mergers.

Non-linear power spectrum and forecasts for Generalized Cubic Covariant Galileon
To fully exploit the data from next generation surveys, we need an accurate modelling of the matter power spectrum up to non-linear scales.

Supermassive black holes from runaway mergers and accretion in nuclear star clusters
The associated gravitational-wave signals of high-redshift extreme mass-ratio inspirals are a unique signature of the nuclear star cluster scenario.
