Dr. Jane Smith

Astrophysicist

I hold a PhD in Astrophysics from the University of Cambridge, specialising in stellar dynamics, galactic evolution, and numerical methods. I believe in open science and try to contribute by sharing my papers, blog posts, and lecture notes.

Stellar Feedback in Dwarf Galaxies

I show that bursty supernova-driven feedback in dwarf galaxies simultaneously transforms dark-matter cusps into cores and heats old stellar populations, producing the tight observed scaling relations between dispersion and luminosity without fine-tuning.
