Developing ETHOS

Given the success of our paper on SIDM and DAOs, I have decided to expand the scope of this Marie Curie project by developing a generalization of current theory of structure formation. This Effective THeory of Structure formation (ETHOS) aims at including a broad range of new dark matter interactions (including among other possibilities SIDM and DAOs) in the modelling of galaxy formation and evolution (see figure below). I came up with the acronym ETHOS inspired by one of the meanings of the Greek word: "essence", since the main goal of the theory is to explore the dark matter particle properties that are essential in galaxy formation/evolution.

This work is in collaboration with Mark Vogelsberger, Kris Sigurdson, Francis-Yan Cyr-Racine, Torsten Bringmann and Christoph Pfrommer.
