Hi, and welcome to my website! My name is Elaad Applebaum, and I am data scientist at Very. I earned a PhD in astrophysics at Rutgers, advised by Dr. Alyson Brooks. Feel free to read about the science I do using the links above, as well as a bit about my interests. If you have any questions, comments, or just want to say hello, feel free to contact me.

Recent news: My submission to name a star and exoplanet system was the runner-up of over 900 entries! See the contest page for more information, and to see the winning name.


My research focuses on using cosmological simulations to help answer astrophysical questions

  • Dwarf Galaxies

    Dwarf galaxies are both the smallest and the most abundant galaxies, and are some of the best tests of our astrophysical and cosmological theories. My current interest lies in tying our simulated dwarf galaxies to current and future observations. Surveys like LSST will provide an unprecedented view of the nearby Universe, and theoretical simulations will be key in interpreting these results. In particular, I am interested in ultra-faint dwarf galaxies, which are galaxies with as few as several hundred or thousand stars.

  • About the Simulations

    These simulations form and evolve realistic galaxies in large volumes. I study simulations run with the N-Body + SPH code ChaNGa, meaning the equations governing gravity and fluid dynamics are solved simultaneously.

  • Star Formation

    What drives star formation in galaxies? Why do galaxies stop forming stars? How can we connect stellar populations in simulations to ones that we see in observations? I focus on answering these questions and more.

    Since simulation resolution is limited by computational resources, analytic prescriptions for star formation must be included. Recent work has focused on building physically motivated star formation and feedback schemes.


I am not presently teaching any courses, as I am support by an NSF grant.

I was previously supported by the Blue Waters Fellowship.

    Courses I have taught include:

  • Physics 124H: Analytical Physics IB Honors (Rutgers, Course Assistant)
  • Physics 123H: Analytical Physics IA Honors (Rutgers)
  • Physics 343: Observational Radio Astronomy (Rutgers)
  • Physics 227: Analytical Physics IIA, Electricity and Magnetism (Rutgers)
  • Physics 211: Introduction to Classical Mechanics (UIUC)
  • Physics 100: Thinking About Physics (UIUC)
