Welcome to my little corner of the internet. My name is Nathan Deg and I am an astrophysicist. Currently I am a SARChI post-doctoral researcher at UCT in the Cape Town. Before that I did my Masters and Ph.D. work at Queen’s University in Kingston, Ontario, Canada.
My research focuses on numerical simulations of isolated and interacting pairs of galaxies as well as using numerical methods (including simulations) to model real objects. I think it’s incredibly exciting to be able to make something in a computer that acts like real galaxies. More than that, it’s fascinating to then explore the model to learn about the hidden structure of the object, like the dark matter halo.
The name of the site comes from the fact that I make a lot of mock observations of simulations. Rather than looking at real photons, like observational astronomers, I usually generate and study virtual ones.
I’m also passionate about teaching and outreach. Astronomy and astrophysics has a power to inspire people and to deeply change how they see themselves in the Universe. Seeing people gain that understanding and have one of those wonderful ‘a-ha’ moments is one of the most rewarding things that I can do.
This page has a summary of my research and gives access to a few of the tools that I use. In addition, I have a small blog with some of my thoughts about astronomy and astrophysics, stories of my own travels, and summaries of papers and conferences that I think are interesting. I hope you enjoy it and have a great time!
