Satellite trail identification in GalaxyZoo images

Last year I attended the .dotastro 5 conference in Boston (and I will be at the successor, .dostastro 6 this year in Chicago). It was a really fun conference to attend, since astronomy is a field I'm trying to eventually be able to contribute to in a non-amateurish way. Coming from the computational side of … Continue reading Satellite trail identification in GalaxyZoo images

Basic astronomy databases with FSharp

This is a short post about a small experiment migrating some Python code for working with astronomical databases to FSharp.  The basic task that I want to perform is to take an object identifier for an object from the Sloan Digital Sky Survey (SDSS) DR10 and look up what it is known to be. For … Continue reading Basic astronomy databases with FSharp

Numerical optimization informed by computational cost for simulation tuning

Here's another short post that refers interested people to a recently accepted paper for publication. M. A. Abramson, T. J. Asaki, J. E. Dennis, Jr., R. Magallanez, and M. J. Sottile. "Efficently solving computationally expensive optimization problems with CPU time-related functions", to appear in Structural and Multidisciplinary Optimization. A preprint lives here. The abstract is: … Continue reading Numerical optimization informed by computational cost for simulation tuning
