Journal Article
Khan, N., Middleton, M., Wiktorowicz, G., Dauser, T., Roberts, T., & Wilms, J. (2022). The impact of precession on the observed population of ULXs. Monthly Notices of the Royal Astronomical Society, 509(2), 2493-2506. https://doi.org/10.1093/mnras/stab3049

The discovery of neutron stars (NSs) powering several ultraluminous X-ray sources (ULXs) raises important questions about the nature of the underlying population. In this paper, we build on previous work studying simulated populations by incorporatin... Read More about The impact of precession on the observed population of ULXs.

We study and model the properties of galaxy clusters in the normal-branch Dvali–Gabadadze–Porrati (nDGP) model of gravity, which is representative of a wide class of theories that exhibit the Vainshtein screening mechanism. Using the first cosmologic... Read More about A general framework to test gravity using galaxy clusters IV: cluster and halo properties in DGP gravity.

We present a Markov chain Monte Carlo pipeline that can be used for robust and unbiased constraints of f(R) gravity using galaxy cluster number counts. This pipeline makes use of a detailed modelling of the halo mass function in f(R) gravity, which i... Read More about A general framework to test gravity using galaxy clusters – V.

The halo light cone catalogues of AbacusSummit (2021)
Journal Article

We describe a method for generating halo catalogues on the light-cone using the ABACUSSUMMIT suite of N-body simulations. The main application of these catalogues is the construction of realistic mock galaxy catalogues and weak lensing maps on the sk... Read More about The halo light cone catalogues of AbacusSummit.

THz electrometry with Rydberg atoms and all IR lasers (2021)
Presentation / Conference Contribution
Chen, S., Reed, D., Downes, L. A., MacKellar, A. R., Almuhawish, N. F., Jamieson, M. J., Adams, C. S., & Weatherill, K. J. (2021, December). THz electrometry with Rydberg atoms and all IR lasers. Presented at 2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz)

Rydberg electromagnetically induced transparency (EIT) and Autler-Townes (AT) splitting in an atomic vapor cell can be used as novel methods for electric-magnetic field detection. Here we make use of 3 infrared lasers to realize a Rydberg EIT system... Read More about THz electrometry with Rydberg atoms and all IR lasers.

Astrophysical Journal, 920(2), Article 98. https://doi.org/10.3847/1538-4357/ac16d8

The core mass of galaxy clusters is both an important anchor of the radial mass distribution profile and a probe of structure formation. With thousands of strong lensing galaxy clusters being discovered by current and upcoming surveys, timely, effici...
