Astronomical Databases

Simply put, we take enormous amounts of data in modern astronomy. We need effective ways of sorting the results of observations, images, catalogs, and spectra. Databases can hold metadata about the raw observations, supplementary information useful in understand spectra, or derived parameters, such as masses of galaxies.

Web Service access for spectral line databases

The molecule at right is ethylene glycol, a molecule detected in interstellar space. I created the 3D model in Mathematica. Splatalogue is a database for astronomical spectroscopy with enormous amounts of information about molecular lines. I work with the Splatalogue team to deploy web services so that various client applications can access the databases.

The MOL file generator at NIST is quite handy.

Galaxy Databases

I've worked on creating databases for large extragalactic surveys with the Arecibo radio telescope. The catalogs give neutral hydrogen measurements and derived properties of galaxies out to a distance of 250 Megaparsecs. Click here for an example catalog publication.
