The evolution of the galaxy content of dark matter haloes (2016)
Journal Article
Contreras, S., Zehavi, I., Baugh, C., Padilla, N., & Norberg, P. (2017). The evolution of the galaxy content of dark matter haloes. Monthly Notices of the Royal Astronomical Society, 465(3), 2833-2848. https://doi.org/10.1093/mnras/stw2826

We use the halo occupation distribution (HOD) framework to characterize the predictions from two independent galaxy formation models for the galactic content of dark matter haloes and its evolution with redshift. Our galaxy samples correspond to a ra... Read More about The evolution of the galaxy content of dark matter haloes.

Subhalo abundance matching in f(R) gravity (2016)
Journal Article
He, J., Li, B., & Baugh, C. M. (2016). Subhalo abundance matching in f(R) gravity. Physical Review Letters, 117(22), Article 221101. https://doi.org/10.1103/physrevlett.117.221101

Using the liminality N-body simulations of Shi et al., we present the first predictions for galaxy clustering in f(R) gravity using subhalo abundance matching. We find that, for a given galaxy density, even for an f(R) model with fR0=−10−6, for which... Read More about Subhalo abundance matching in f(R) gravity.

The spatial distribution of neutral hydrogen as traced by low H i mass galaxies (2016)
Journal Article
Kim, H., Wyithe, J., Baugh, C., Lagos, C. D. P., Power, C., & Park, J. (2017). The spatial distribution of neutral hydrogen as traced by low H i mass galaxies. Monthly Notices of the Royal Astronomical Society, 465(1), 111-122. https://doi.org/10.1093/mnras/stw2779

The formation and evolution of galaxies with low neutral atomic hydrogen (HI) masses, MHI<108h−2M⊙, are affected by host dark matter halo mass and photoionisation feedback from the UV background after the end of reionization. We study how the physica...

The Extraordinary Amount of Substructure in the Hubble Frontier Fields Cluster Abell 2744 (2016)
Journal Article

We present a joint optical/X-ray analysis of the massive galaxy cluster Abell 2744 (z=0.308). Our strong- and weak-lensing analysis within the central region of the cluster, i.e., at R < 1 Mpc from the brightest cluster galaxy, reveals eight substruc...

A unified multiwavelength model of galaxy formation (2016)
Journal Article

We present a new version of the GALFORM semi-analytical model of galaxy formation. This brings together several previous developments of GALFORM into a single unified model, including a different initial mass function (IMF) in quiescent star formatio...

Measuring galaxy environment with the synergy of future photometric and spectroscopic surveys (2016)
Journal Article
Cucciati, O., Marulli, F., Cimatti, A., Merson, A., Norberg, P., Pozzetti, L., …Branchini, E. (2016). Measuring galaxy environment with the synergy of future photometric and spectroscopic surveys. Monthly Notices of the Royal Astronomical Society, 462(2), 1786-1801. https://doi.org/10.1093/mnras/stw1729

We exploit the synergy between low-resolution spectroscopy and photometric redshifts to study environmental effects on galaxy evolution in slitless spectroscopic surveys from space. As a test case, we consider the future Euclid Deep survey (∼40 deg2)... Read More about Measuring galaxy environment with the synergy of future photometric and spectroscopic surveys.

The clustering of dark matter haloes: scale-dependent bias on quasi-linear scales (2016)
Journal Article
Jose, C., Lacey, C., & Baugh, C. (2016). The clustering of dark matter haloes: scale-dependent bias on quasi-linear scales. Monthly Notices of the Royal Astronomical Society, 463(1), 270-281. https://doi.org/10.1093/mnras/stw1702

We investigate the spatial clustering of dark matter halos, collapsing from 1 − 4σ fluctuations, in the redshift range 0 − 5 using N-body simulations. The halo bias of high redshift halos (z ≥ 2) is found to be strongly non-linear and scale-dependent...

Can We Detect the Color–Density Relation with Photometric Redshifts? (2016)
Journal Article

A variety of methods have been proposed to define and to quantify galaxy environments. While these techniques work well in general with spectroscopic redshift samples, their application to photometric redshift surveys remains uncertain. To investigat...

We investigate the clustering of Lyman-break galaxies (LBGs) at z ∼ 4. Using the hierarchical galaxy formation model GALFORM, we predict, for the first time using a semi-analytical model with feedback from active galactic nuclei (AGN), the angular co...
