Journal Article
Gurung-López, S., Saito, S., Baugh, C. M., Bonoli, S., Lacey, C. G., & Orsi, Á. A. (2021). Determining the systemic redshift of Lyman α emitters with neural networks and improving the measured large-scale clustering. Monthly Notices of the Royal Astronomical Society, 500(1), 603-626. https://doi.org/10.1093/mnras/staa3269

We explore how to mitigate the clustering distortions in Lyman α emitter (LAE) samples caused by the misidentification of the Lyman α (⁠Lyα⁠) wavelength in their Lyα line profiles. We use the Lyα line profiles from our previous LAE theoretical model...

Are Lyα emitters segregated in protoclusters regions? (2020)
Journal Article
Hough, T., Gurung-López, S., Orsi, Á., Cora, S. A., Lacey, C. G., & Baugh, C. M. (2020). Are Lyα emitters segregated in protoclusters regions?. Monthly Notices of the Royal Astronomical Society, 499(2), 2104-2115. https://doi.org/10.1093/mnras/staa3027

The presence of neutral hydrogen in the inter-stellar medium (ISM) and inter-galactic medium (IGM) induces radiative transfer (RT) effects on Lyα photons which affect the observability of Lyα emitters (LAEs). We use the GALFORM semi-analytic model of... Read More about Are Lyα emitters segregated in protoclusters regions?.

Modelling the quenching of star formation activity from the evolution of the colour-magnitude relation in VIPERS (2020)
Journal Article
Manzoni, G., Scodeggio, M., Baugh, C., Norberg, P., De Lucia, G., Fritz, A., Haines, C., Zamorani, G., Gargiulo, A., Guzzo, L., Iovino, A., Małek, K., Pollo, A., Siudek, M., & Vergani, D. (2021).

We study the evolution of the colour-magnitude relation for galaxies in the VIMOS Public Extragalactic Redshift Survey (VIPERS) by introducing the concept of the bright edge, and use this to derive constraints on the quenching of star formation activ...

Do model emission line galaxies live in filaments at z∼1? (2020)
Journal Article
Gonzalez-Perez, V., Cui, W., Contreras, S., Baugh, C., Comparat, J., Griffin, A., Helly, J., Knebe, A., Lacey, C., & Norberg, P. (2020). Do model emission line galaxies live in filaments at z∼1?. Monthly Notices of the Royal Astronomical Society, 498(2), 1852-1870. https://doi.org/10.1093/mnras/staa2504

Current and future cosmological surveys are targeting star-forming galaxies at z∼ 1 with nebular emission lines. We use a state-of-the-art semi-analytical model of galaxy formation and evolution to explore the large scale environment of star-forming...

Towards a non-Gaussian model of redshift space distortions (2020)
Journal Article
Cuesta-Lazaro, C., Li, B., Eggemeier, A., Zarrouk, P., Baugh, C. M., Nishimichi, T., & Takada, M. (2020). Towards a non-Gaussian model of redshift space distortions. Monthly Notices of the Royal Astronomical Society, 498(1), 1175-1193. https://doi.org/10.1093/mnras/staa2249

To understand the nature of the accelerated expansion of the Universe, we need to combine constraints on the expansion rate and growth of structure. The growth rate is usually extracted from 3D galaxy maps by exploiting the effects of peculiar motion... Read More about Towards a non-Gaussian model of redshift space distortions.

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...
