Double copies in 4D AdS gravity are classified one-to-one with orbits of so(2,3) isometry elements via a Penrose-type transform, yielding black holes, branes and other solutions, with extension to multicopies for higher spins.

Phase Transitions in Primary Hair Planar Black Holes and Solitons
New analytic Ricci-flat planar hairy black holes and solitons in AdS show first-order phase transitions controlled by Euclidean time and spatial period ratios, with the soliton preferred over a widening temperature window as hair increases.
