A general framework to test gravity using galaxy clusters IV: cluster and halo properties in DGP gravity (2021)
Journal Article
Mitchell, M. A., Hernández-Aguayo, C., Arnold, C., & Li, B. (2021). A general framework to test gravity using galaxy clusters IV: cluster and halo properties in DGP gravity. Monthly Notices of the Royal Astronomical Society, 508(3), 4140-4156. https://doi.org/10.1093/mnras/stab2817

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.

Galaxy formation in the brane world I: overview and first results (2021)
Journal Article
Hernández-Aguayo, C., Arnold, C., Li, B., & Baugh, C. M. (2021). Galaxy formation in the brane world I: overview and first results. Monthly Notices of the Royal Astronomical Society, 503(3), 3867-3885. https://doi.org/10.1093/mnras/stab694

We carry out ‘full-physics’ hydrodynamical simulations of galaxy formation in the normal-branch Dvali–Gabadadze–Porrati (nDGP) braneworld model using a new modified version of the AREPO code and the IllustrisTNG galaxy formation model. We simulate tw... Read More about Galaxy formation in the brane world I: overview and first results.

Building a digital twin of a luminous red galaxy spectroscopic survey: galaxy properties and clustering covariance (2021)
Journal Article
Hernández-Aguayo, C., Prada, F., Baugh, C. M., & Klypin, A. (2021). Building a digital twin of a luminous red galaxy spectroscopic survey: galaxy properties and clustering covariance. Monthly Notices of the Royal Astronomical Society, 503(2), 2318-2339. https://doi.org/10.1093/mnras/stab434

Upcoming surveys will use a variety of galaxy selections to map the large-scale structure of the Universe. It is important to make accurate predictions for the properties and clustering of such galaxies, including the errors on these statistics. Here...

The impact of modified gravity on the Sunyaev–Zeldovich effect (2020)
Journal Article
Mitchell, M. A., Arnold, C., Hernández-Aguayo, C., & Li, B. (2021). The impact of modified gravity on the Sunyaev–Zeldovich effect. Monthly Notices of the Royal Astronomical Society, 501(3), 4565-4578. https://doi.org/10.1093/mnras/staa3941

We study the effects of two popular modified gravity theories, which incorporate very different screening mechanisms, on the angular power spectra of the thermal (tSZ) and kinematic (kSZ) components of the Sunyaev–Zeldovich effect. Using the first co... Read More about The impact of modified gravity on the Sunyaev–Zeldovich effect.

Measuring the baryon acoustic oscillation peak position with different galaxy selections (2020)
Journal Article
Hernández-Aguayo, C., Cautun, M., Smith, A., Baugh, C. M., & Li, B. (2020). Measuring the baryon acoustic oscillation peak position with different galaxy selections. Monthly Notices of the Royal Astronomical Society, 494(3), 3120-3130. https://doi.org/10.1093/mnras/staa973

We investigate if, for a fixed number density of targets and redshift, there is an optimal way to select a galaxy sample in order to measure the baryon acoustic oscillation (BAO) scale, which is used as a standard ruler to constrain the cosmic expans...
