Journal Article
Lovell, M., Gonzalez-Perez, V., Bose, S., Boyarsky, A., Cole, S., Frenk, C., & Ruchayskiy, O. (2017). Addressing the too big to fail problem with baryon physics and sterile neutrino dark matter. Monthly Notices of the Royal Astronomical Society, 468(3), 2836-2849. https://doi.org/10.1093/mnras/stx621

N-body dark matter simulations of structure formation in the Λ cold dark matter (ΛCDM) model predict a population of subhaloes within Galactic haloes that have higher central densities than inferred for the Milky Way satellites, a tension known as th...

Winds of change: reionization by starburst galaxies (2017)
Journal Article
Sharma, M., Theuns, T., Frenk, C., Bower, R., Crain, R., Schaller, M., & Schaye, J. (2017). Winds of change: reionization by starburst galaxies. Monthly Notices of the Royal Astronomical Society, 468(2), 2176-2188. https://doi.org/10.1093/mnras/stx578

We investigate the properties of the galaxies that reionized the Universe and the history of cosmic reionization using the ‘Evolution and Assembly of Galaxies and their Environments’ (eagle) cosmological hydrodynamical simulations. We obtain the evol... Read More about Winds of change: reionization by starburst galaxies.

Projection effects in the strong lensing study of subhaloes (2017)
Journal Article
Li, R., Frenk, C., Cole, S., Wang, Q., & Gao, L. (2017). Projection effects in the strong lensing study of subhaloes. Monthly Notices of the Royal Astronomical Society, 468(2), 1426-1432. https://doi.org/10.1093/mnras/stx554

The defining characteristic of the cold dark matter (CDM) hypothesis is the presence of a very large number of low-mass haloes, too small to have made a visible galaxy. Other hypotheses for the nature of the dark matter, such as warm dark matter (WDM... Read More about Projection effects in the strong lensing study of subhaloes.

Particle tagging and its implications for stellar population dynamics (2017)
Journal Article
Le Bret, T., Pontzen, A., Cooper, A., Frenk, C., Zolotov, A., Brooks, A., Governato, F., & Parry, O. (2017). Particle tagging and its implications for stellar population dynamics. Monthly Notices of the Royal Astronomical Society, 468(3), 3212-3222. https://doi.org/10.1093/mnras/stx552

We establish a controlled comparison between the properties of galactic stellar haloes obtained with hydrodynamical simulations and with ‘particle tagging’. Tagging is a fast way to obtain stellar population dynamics: instead of tracking gas and star... Read More about Particle tagging and its implications for stellar population dynamics.

Gravitational redshift and asymmetric redshift-space distortions for stacked clusters (2017)
Journal Article
Cai, Y., Kaiser, N., Cole, S., & Frenk, C. (2017). Gravitational redshift and asymmetric redshift-space distortions for stacked clusters. Monthly Notices of the Royal Astronomical Society, 468(2), 1981-1993. https://doi.org/10.1093/mnras/stx469

We derive the expression for the observed redshift in the weak field limit in the observer's past light cone, including all relativistic terms up to second order in velocity. We then apply it to compute the cluster–galaxy cross-correlation functions... Read More about Gravitational redshift and asymmetric redshift-space distortions for stacked clusters.

Shaken and stirred: the Milky Way's dark substructures (2017)
Journal Article
Sawala, T., Pihajoki, P., Johansson, P., Frenk, C., Navarro, J., Oman, K., & White, S. (2017). Shaken and stirred: the Milky Way's dark substructures. Monthly Notices of the Royal Astronomical Society, 467(4), 4383-4400. https://doi.org/10.1093/mnras/stx360

The predicted abundance and properties of the low-mass substructures embedded inside larger dark matter haloes differ sharply among alternative dark matter models. Too small to host galaxies themselves, these subhaloes may still be detected via gravi... Read More about Shaken and stirred: the Milky Way's dark substructures.

The tangential velocity excess of the Milky Way satellites (2017)
Journal Article

We estimate the systemic orbital kinematics of the Milky Way classical satellites and compare them with predictions from the Λ cold dark matter (ΛCDM) model derived from a semi-analytical galaxy formation model applied to high-resolution cosmological...

We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved—cosmology, astrophysics, nuclear, and particle physics—in each case viewed from both theoretical and experimental...

We introduce a suite of 30 cosmological magneto-hydrodynamical zoom simulations of the formation of galaxies in isolated Milky Way mass dark haloes. These were carried out with the moving mesh code arepo, together with a comprehensive model for galax...
