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?.

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...

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...

We model the large-scale linear galaxy bias bg(x, z) as a function of redshift z and observed absolute magnitude threshold x for broad-band continuum emission from the far-infrared to ultraviolet, as well as for prominent emission lines, such as the...

Telescopes to be launched over the next decade-and-a-half, such as JWST, EUCLID, ATHENA and Lynx, promise to revolutionise the study of the high redshift Universe and greatly advance our understanding of the early stages of galaxy formation. We use a... Read More about AGNs at the cosmic dawn: predictions for future surveys from a ΛCDM cosmological model.

Sensitivity analysis of a galaxy formation model (2019)
Journal Article

We present the first application of a variance-based sensitivity analysis (SA) to a model that aims to predict the evolution and properties of the whole galaxy population. SA is a well-established technique in other quantitative sciences, but is a re... Read More about Sensitivity analysis of a galaxy formation model.

We investigate a conceptual modification of the halo occupation distribution approach, using the halos’ present-day maximal circular velocity, Vmax, as an alternative to halo mass. In particular, using a semianalytic galaxy formation model applied to...

In the near future galaxy surveys will target Lyman alpha emitting galaxies (LAEs) to unveil the nature of dark energy.
