Journal Article
Smith, A., Grove, C., Cole, S., Norberg, P., Zarrouk, P., Yuan, S., Aguilar, J., Ahlen, S., Brooks, D., Claybaugh, T., de la Macorra, A., Doel, P., Forero-Romero, J. E., Gaztañaga, E., Gontcho, S. G. A., Hahn, C., Kehoe, R., Kremin, A., Levi, M. E., Manera, M., …Zhou, Z. (2024). Generating mock galaxy catalogues for flux-limited samples like the DESI Bright Galaxy Survey. Monthly Notices of the Royal Astronomical Society, 532(1), 903-919. https://doi.org/10.1093/mnras/stae1503

Accurate mock galaxy catalogues are crucial to validate analysis pipelines used to constrain dark energy models. We present a fast HOD-fitting method which we apply to the AbacusSummit simulations to create a set of mock catalogues for the DESI Brigh...

A new test of gravity – I. Introduction to the method (2024)
Journal Article
Armijo, J., Baugh, C. M., Norberg, P., & Padilla, N. D. (2024). A new test of gravity – I. Introduction to the method. Monthly Notices of the Royal Astronomical Society, 529(3), 2866-2876. https://doi.org/10.1093/mnras/stae719

We introduce a new scheme based on the marked correlation function to probe gravity using the large-scale structure of the Universe. We illustrate our approach by applying it to simulations of the metric-variation f(R) modified gravity theory and gen... Read More about A new test of gravity – I. Introduction to the method.

Monthly Notices of the Royal Astronomical Society, 530(2), 1394-1413. https://doi.org/10.1093/mnras/stae659

We use the GALFORM semi-analytical galaxy formation model implemented in the Planck Millennium N-body simulation to build a mock galaxy catalogue on an observer’s past lightcone. The mass resolution of this N-body simulation is almost an order of mag... Read More about The PAU Survey: a new constraint on galaxy formation models using the observed colour redshift relation.

A new test of gravity – II. Application of marked correlation functions to luminous red galaxy samples (2024)
Journal Article
Armijo, J., Baugh, C. M., Norberg, P., & Padilla, N. D. (2024). A new test of gravity – II. Application of marked correlation functions to luminous red galaxy samples. Monthly Notices of the Royal Astronomical Society, 528(4), 6631-6636. https://doi.org/10.1093/mnras/stae449

We apply the marked correlation function test proposed by Armijo et al. (Paper I) to samples of luminous red galaxies (LRGs) from the final data release of the Sloan Digital Sky Survey (SDSS) III. The test assigns a density-dependent mark to galaxies... Read More about A new test of gravity – II. Application of marked correlation functions to luminous red galaxy samples.
