A new test of galaxy formation physics. Monthly Notices of the Royal Astronomical Society, 443(2), 1002-1021. https://doi.org/10.1093/mnras/stu1209

We study the atomic (H I) and molecular hydrogen (H2) contents of early-type galaxies (ETGs) and their gas sources using the GALFORM model of galaxy formation. This model uses a self-consistent calculation of the star formation rate, which depends on... Read More about The origin of the atomic and molecular gas contents of early-type galaxies – I.

Using the Milky Way satellites to study interactions between cold dark matter and radiation (2014)
Journal Article

The cold dark matter (CDM) model faces persistent challenges on small scales. In particular, the model significantly overestimates the number of satellite galaxies around the Milky Way. Attempts to solve this problem remain controversial and have eve... Read More about Using the Milky Way satellites to study interactions between cold dark matter and radiation.

Modified gravity with massive neutrinos as a testable alternative cosmological model (2014)
Journal Article

We show that, in the presence of massive neutrinos, the Galileon gravity model provides a very good fit to the current cosmic microwave background (CMB) temperature, CMB lensing and baryonic acoustic oscillation data. This model, which we dub νGalile... Read More about Modified gravity with massive neutrinos as a testable alternative cosmological model.

Extending the halo mass resolution of N-body simulations (2014)
Journal Article
Angulo, R., Baugh, C., Frenk, C., & Lacey, C. (2014). Extending the halo mass resolution of N-body simulations. Monthly Notices of the Royal Astronomical Society, 442(4), 3256-3265. https://doi.org/10.1093/mnras/stu1084

We present a scheme to extend the halo mass resolution of dark matter N-body simulations. The method uses the simulated density field to predict the number of sub-resolution haloes expected in different regions, taking as input the abundance and the...
