Simulations of facular magnetic fields on cool stars I: Main sequence stars with solar metallicity

Posted by klaurent Stanford

Kavli Affiliate: Robert Cameron | Summary:Stellar convection in the presence of magnetic field affects the emergent intensity, as well as the structure and evolution of cool main-sequence dwarfs. We aim to understand the effect of faculae-like field strengths on near-surface stellar convection using 3D radiative MHD simulations of near-surface magneto-convection. We compare simulations of F, […]

Searching for Cosmological Collider in the Planck CMB Data II: collider templates and Modal analysis

Posted by klaurent Cambridge

Kavli Affiliate: E. P. S. Shellard | Summary:Signatures of massive particles during inflation are highly informative targets for cosmological experiments. With recent progress on both theoretical and observational frontiers, we have reached the point where these novel signals of primordial non-Gaussianities (PNG) can be systematically tested with increasingly precise data. In this paper, we present […]
