Abstract

The metal-poor, irregular dwarf galaxy called I Zwicky 18 has been one of my constant obsessions during my scientific career. The galaxy emits an unprecedented amount of hard ionizing radiation together with certain emission features in its spectrum. To explain this, a theorist like me has to put together a complex hypothesis based on reliable computer models, and compare its predictions to all available observations in the literature. In this talk, I share my curious story of the past 12 years tackling the case of I Zwicky 18.
