Dark matter–radiation interactions: the structure of Milky Way satellite galaxies (2016)
Journal Article
Schewtschenko, J., Baugh, C., Wilkinson, R., Boehm, C., Pascoli, S., & Sawala, T. (2016). Dark matter–radiation interactions: the structure of Milky Way satellite galaxies. Monthly Notices of the Royal Astronomical Society, 461(3), 2282-2287. https://doi.org/10.1093/mnras/stw1078

In the thermal dark matter (DM) paradigm, primordial interactions between DM and Standard Model particles are responsible for the observed DM relic density. In Boehm et al. (2014), we showed that weak-strength interactions between DM and radiation (p... Read More about Dark matter–radiation interactions: the structure of Milky Way satellite galaxies.

Galaxy cluster lensing masses in modified lensing potentials (2015)
Journal Article
Barreira, A., Li, B., Jennings, E., Merten, J., King, L., Baugh, C., & Pascoli, S. (2015). Galaxy cluster lensing masses in modified lensing potentials. Monthly Notices of the Royal Astronomical Society, 454(4), 4085-4102. https://doi.org/10.1093/mnras/stv2211

We determine the concentration–mass relation of 19 X-ray selected galaxy clusters from the Cluster Lensing and Supernova Survey with Hubble survey in theories of gravity that directly modify the lensing potential. We model the clusters as Navarro–Fre... Read More about Galaxy cluster lensing masses in modified lensing potentials.

Mixing angle and phase correlations from A5 with generalized CP and their prospects for discovery (2015)
Journal Article
Ballett, P., Pascoli, S., & Turner, J. (2015). Mixing angle and phase correlations from A5 with generalized CP and their prospects for discovery. Physical Review D, 92(9), Article 093008. https://doi.org/10.1103/physrevd.92.093008

The observed leptonic mixing pattern could be explained by the presence of a discrete flavor symmetry broken into residual subgroups at low energies. In this scenario, a residual generalized charge parity (CP) symmetry allows the parameters of the Po...

Weak lensing by voids in modified lensing potentials (2015)
Journal Article
Barreira, A., Cautun, M., Li, B., Baugh, C., & Pascoli, S. (2015). Weak lensing by voids in modified lensing potentials. Journal of Cosmology and Astroparticle Physics, 2015(08), https://doi.org/10.1088/1475-7516/2015/08/028

We study lensing by voids in Cubic Galileon and Nonlocal gravity cosmologies, which are examples of theories of gravity that modify the lensing potential. We find voids in the dark matter and halo density fields of N-body simulations and compute thei... Read More about Weak lensing by voids in modified lensing potentials.

Dark matter-radiation interactions: the impact on dark matter haloes (2015)
Journal Article
Schewtschenko, J., Wilkinson, R., Baugh, C., Boehm, C., & Pascoli, S. (2015). Dark matter-radiation interactions: the impact on dark matter haloes. Monthly Notices of the Royal Astronomical Society, 449(4), 3587-3596. https://doi.org/10.1093/mnras/stv431

Interactions between dark matter (DM) and radiation (photons or neutrinos) in the early Universe suppress density fluctuations on small mass scales. Here, we perform a thorough analysis of structure formation in the fully non-linear regime using N-bo... Read More about Dark matter-radiation interactions: the impact on dark matter haloes.

Testing solar lepton mixing sum rules in neutrino oscillation experiments (2014)
Journal Article
Ballett, P., King, S., Luhn, C., Pascoli, S., & Schmidt, M. (2014). Testing solar lepton mixing sum rules in neutrino oscillation experiments. Journal of High Energy Physics, 2014(12), Article 122. https://doi.org/10.1007/jhep12%282014%29122

Small discrete family symmetries such as S4, A4 or A5 may lead to simple leading-order predictions for the neutrino mixing matrix such as the bimaximal, tribimaximal or golden ratio mixing patterns, which may be brought into agreement with experiment...

Nonlinear structure formation in Nonlocal Gravity (2014)
Journal Article
Barreira, A., Li, B., Hellwing, W., Baugh, C., & Pascoli, S. (2014). Nonlinear structure formation in Nonlocal Gravity. Journal of Cosmology and Astroparticle Physics, 2014(09), Article 031. https://doi.org/10.1088/1475-7516/2014/09/031

We study the nonlinear growth of structure in nonlocal gravity models with the aid of N-body simulation and the spherical collapse and halo models. We focus on a model in which the inverse-squared of the d'Alembertian operator acts on the Ricci scala... Read More about Nonlinear structure formation in Nonlocal Gravity.

Using the Milky Way satellites to study interactions between cold dark matter and radiation (2014)
Journal Article
Boehm, C., Schewtschenko, J., Wilkinson, R., Baugh, C., & Pascoli, S. (2014). Using the Milky Way satellites to study interactions between cold dark matter and radiation. Monthly Notices of the Royal Astronomical Society: Letters, 445(1), L31-L35. https://doi.org/10.1093/mnrasl/slu115

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.

The observational status of Galileon gravity after Planck (2014)
Journal Article
Barreira, A., Li, B., Baugh, C., & Pascoli, S. (2014). The observational status of Galileon gravity after Planck. Journal of Cosmology and Astroparticle Physics, 2014(08), Article 059. https://doi.org/10.1088/1475-7516/2014/08/059

We use the latest CMB data from Planck, together with BAO measurements, to constrain the full parameter space of Galileon gravity. We constrain separately the three main branches of the theory known as the Cubic, Quartic and Quintic models, and find... Read More about The observational status of Galileon gravity after Planck.
