Journal Article
Shirasaki, M., Nishimichi, T., Li, B., & Higuchi, Y. (2017). The imprint of f(R) gravity on weak gravitational lensing II: Information content in cosmic shear statistics. Monthly Notices of the Royal Astronomical Society, 466(2), 2402-2417. https://doi.org/10.1093/mnras/stw3254

We investigate the information content of various cosmic shear statistics on the theory of gravity. Focusing on the Hu–Sawicki-type f(R) model, we perform a set of ray-tracing simulations and measure the convergence bispectrum, peak counts and Minkow...

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.

We refine the mass and environment dependent spherical collapse model of chameleon f(R) gravity by calibrating a phenomenological correction inspired by the parameterized post-Friedmann framework against high-resolution N-body simulations. We employ... Read More about Cluster abundance in chameleon f(R) gravity I: toward an accurate halo mass function prediction.

The H.E.S.S. Collaboration has reported a high-energy spherically symmetric diffuse γ-ray emission in the inner 50 pc of the Milky Way, up to ∼50 TeV. Here, we propose a leptonic model which provides an alternative to the hadronic scenario presented...
