Hierarchical Population Inference with Normalizing Flows for Binary Black Holes
Leonardo Iampieri, Simone Mastrogiovanni
Low-dimensional parametric mass models are standard in gravitational-wave population inference, but their rigidity can bias the recovered distribution and the conclusions drawn fro…

Measuring the speed of gravity and the cosmic expansion with time delays between gravity and light from binary neutron stars
Leonardo Iampieri, Simone Mastrogiovanni, Francesco Pannarale
The first observation of a gravitational wave (GW) and a short gamma-ray burst (sGRB) emitted by the same binary neutron star (BNS) merger officially opened the field of GW multime…
