Great experience giving a public talk at Alden Planetarium (Worcester, MA) this weekend about How to Make a Galaxy in a Supercomputer. Thanks to the organizers of the EcoTarium Astronomy Speaker Series and to everyone for the super interesting questions, specially the youngest attendees (5-7 years old?) wondering about the difference between the formation of elliptical and spiral galaxies, or how supermassive black holes move around in galaxies in the early universe!
