abstract
The fraction of local dwarf galaxies that hosts massive black holes is arguably the cleanest diagnostic of the dominant seed formation mechanism of today's supermassive black holes. A 5 per cent constraint on this quantity can be achieved with AXIS observations of 3300 galaxies across the mass spectrum through a combination of serendipitous extra-galactic fields plus a dedicated 1 Msec GO program.

Probability of gravitational-wave lensing by intermediate-mass black holes and globular clusters
The rate of compound gravitational-wave lensing by intermediate-mass black holes in globular clusters is at most about 10^-3 of galaxy-scale lensed events, disfavoring GW231123 as such an event.
