I’m pleased to say that my MSc. work done with @pbarmby.bsky.social and J. Young has been accepted for publication and is now up on the arXiv! We study star formation scaling relations in LSB galaxies and try to understand their faint appearance

Fitting the Shadows: Star Formation Scaling Relations in the Low Surface Brightness Regime
Classical low surface brightness (LSB) galaxies pose an important challenge to galaxy evolution models. While they are found to host large reservoirs of atomic hydrogen, they display low stellar and s...

Minor planet 299631 has been named for Kaylie Green, who was a PhD student in our department when she passed away almost 2 years ago. A fitting memorial for someone who practiced and shared astronomy with such passion. www.wgsbn-iau.org/files/Bullet...

The stories we tell about science shape, from a young age, how we think about who scientists are and what they do. That means films hold an enormous power for change. Read more on the Columbia University Press blog:
