Baryogenesis through Asymmetric Hawking Radiation from Primordial Black Holes as Dark Matter
Alexis Boudon, Benjamin Bose, Hyat Huang +1
We examine the extent to which primordial black holes (PBHs) can constitute the observed dark matter while also giving rise to the measured matter-antimatter asymmetry and account…
Modelling Non-Linear Effects of Dark Energy
Benjamin Bose, Marco Baldi, Alkistis Pourtsidou
We investigate the capabilities of perturbation theory in capturing non-linear effects of dark energy. We test constant and evolving models, as well as models involving moment…
Stable Islands of Weak Gravity
Linus Thummel, Benjamin Bose, Alkistis Pourtsidou
We present an exploration of the phenomenology of Horndeski gravity, focusing on regimes that produce weak gravity compared to General Relativity. This letter introduces a novel me…
CMB lensing bi-spectrum: assessing analytical predictions against full-sky lensing simulations
Toshiya Namikawa, Benjamin Bose, François R. Bouchet +2
Cosmic microwave background (CMB) lensing is an integrated effect whose kernel is greater than half the peak value in the range . Measuring this effect offers a powerful too…
Revealing modified gravity signal in matter and halo hierarchical clustering
Wojciech A. Hellwing, Kazuya Koyama, Benjamin Bose +1
We use a set of N-body simulations employing a modified gravity (MG) model with Vainshtein screening to study matter and halo hierarchical clustering. As test-case scenarios we con…
Extending MGCAMB tests of gravity to nonlinear scales
Zhuangfei Wang, Daniela Saadeh, Kazuya Koyama +4
Modified Growth with {\tt CAMB} ({\tt MGCAMB}) is a patch for the Einstein-Boltzmann solver {\tt CAMB} for cosmological tests of gravity. Until now, {\tt MGCAMB} was limited to sca…
