Hyungsuk (Tak) Tak is an Assistant Professor of Statistics, Astronomy and Astrophysics at Penn State.
Tak received his Ph.D. in Statistics from Harvard University in 2016. He received his A.M. in Statistics from Harvard University in 2012, and a B.A. in Statistics from Korea University in 2009.
In preparation for the era of the Legacy Survey of Space and Time (LSST), Tak works closely with astronomers and astrophysicists to analyze astronomical time series and imaging data, developing practically motivated data analytic tools. Specifically, his research interests are (i) statistical challenges in astronomical data analysis (heteroscedasticity, outliers, irregularly-spaced time series, (ii) time delay cosmography for the Hubble constant estimation, (iii) statistical computation (data augmentation/missing data/Markov chain Monte Carlo), and (iv) Bayesian hierarchical modeling with frequency coverage evaluation.

How do supermassive black holes get super massive?
2024-09-09
UNIVERSITY PARK, Pa. — By combining forefront X-ray observations with state-of-the-art supercomputer simulations of the buildup of galaxies over cosmic history, researchers have provided the best modeling to date of the growth of the supermassive black holes found in the centers of galaxies. Using this hybrid approach, a research team led by Penn State astronomers derived a complete picture of black-hole growth over 12 billion years, from the Universe’s infancy at around 1.8 billion years old to now at 13.8 billion years old.
