Hey! You've found Aaron!

a trainee astronomer at Rutgers / CCA

I am currently pursuing my Ph.D. in physics in the Department of Physics and Astronomy under the supervision of Prof. Rachel Somerville. My main interest lies in model galaxy formation and evolution at ultrahigh redshifts. You can also learn more about me from my latest interview!

Science

I use the well-established Santa Cruz semi-analytic model (SAM) to study the formation and evolution of galaxies at ultrahigh redshifts (up to z ~ 15!). Currently, I am using the SAM to make predictions for the long-anticipated JWST telescope. Taking advantage of the model's efficiency, I also study the impact of uncertainties in the current galaxy formation model by systematically varying subgrid physical parameters. WIth these galaxies predicted by our physically motivate models, I study their impact on cosmic reionization.

Short Bio

I was born and raised in Hong Kong! In 2007, I moved to Hawaii with my family and completed high school in 2009. After brief attendance at the University of Hawaii at Manoa, I moved to California and obtained my bachelor's degree in physics and mathematics from the University of San Francisco. Immediately after that, I moved to New Jersey for graduate study in Astrophysics.




Use of Name

In my pre-2016 career, I went by "Long Yan Yung", which is a direct phonetic translation of my name under a scheme established during the British Colonial Hong Kong time. Although my name has its Chinese origin, it follows neither the more popular pronunciation schemes established by the Chinese or the Taiwanese. In order to elimintate pronounciation confusion, I have initialized "Long Yan" to L.Y. and go by Aaron, as it is always part of my name.
