no code implementations11 Feb 2021 Federico Lelli, Enrico M. Di Teodoro, Filippo Fraternali, Allison W. S. Man, Zhi-Yu Zhang, Carlos De Breuck, Timothy A. Davis, Roberto Maiolino

Cosmological models predict that galaxies forming in the early Universe experience a chaotic phase of gas accretion and star formation, followed by gas ejection due to feedback processes.

A cautionary tale in fitting galaxy rotation curves with Bayesian techniques: does Newton's constant vary from galaxy to galaxy?

no code implementations27 Jan 2021 Pengfei Li, Federico Lelli, Stacy McGaugh, James Schombert, Kyu-Hyun Chae

The application of Bayesian techniques to astronomical data is generally non-trivial because the fitting parameters can be strongly degenerated and the formal uncertainties are themselves uncertain.
