Query: New Gravitational Memories   The conventional gravitational memory effect is a relative displacement in
the position of two detectors induced by radiative energy flux. We find a new
type of gravitational `spin memory' in which beams on clockwise and
counterclockwise orbits acquire a relative delay induced by radiative angular
momentum flux. It has recently been shown that the displacement memory formula
is a Fourier transform in time of Weinberg's soft graviton theorem. Here we see
that the spin memory formula is a Fourier transform in time of the
recently-discovered subleading soft graviton theorem.
