Abstract
We show how electric and magnetic Carroll gravity can be constructed using conformal methods. We first review the conformal approach to relativistic Einstein-Hilbert gravity. Next, we consider a set of independent and dependent gauge fields of the conformal Carroll algebra, paying special attention to the way intrinsic torsion tensor components appear in their transformation rules. We then couple a single electric/magnetic massless scalar to these conformal Carroll gauge fields and show how, upon gauge-fixing the dilatations, we obtain a non-conformal version of electric/magnetic Carroll gravity.
