About
Welcome to my blog. My name is Keaton Bell. I am an assistant professor of astrophysics at Queens College of the City University of New York. I study various aspects of time-domain variability of stars, particularly those involving stellar pulsations, white dwarfs, and exoplanets. Learn more about my research on my research group’s webpage.
I set up this blog to host short, generally non-astronomy-specific public notes that might prove useful to others. These are things that I wish had been easier to Google when I needed the answers. I will mostly post statistical, mathematical, programming, and data visualization tricks that I developed in the course of my research. I may also publish the results of some just-for-fun data science experiments on this site.
- Bootstrapping a significance threshold for periodogram analysis
- How data sampling affects the Fourier transform periodogram
- Three statistical tests for average spacing among numbers
- Confidence intervals for 2D Gaussian mixture models with contours
- What's the expected average value of a noisy amplitude spectrum?
