Towards convergence of turbulent dynamo amplification in cosmological simulations of galaxies

Posted by klaurent Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Sergio Martin-Alvarez, Julien Devriendt, Adrianne Slyz, Debora Sijacki, Mark L. A. Richardson | Summary: Our understanding of the process through which magnetic fields reached their observed strengths in present-day galaxies remains incomplete. One of the advocated solutions is a turbulent dynamo mechanism that rapidly amplifies weak magnetic […]

Neutron stars in massive scalar-Gauss-Bonnet gravity: Spherical structure and time-independent perturbations

Posted by klaurent Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Rui Xu, Yong Gao, Lijing Shao, , | Summary: The class of scalar-tensor theories with the scalar field coupling to the Gauss-Bonnet invariant has drawn great interest since solutions of spontaneous scalarization were found for black holes in these theories. We contribute to the existing literature a […]
