Recent graduate Chandler Osborne along with Professor Samir Salim, have been awarded a Hubble Space Telescope Archival Grant to produce an Hubble Space Telescope (HST)/ Sloan Digital Sky Survey (SDSS) Atlas and Morphological Catalog of 7000 SDSS galaxies serendipitously imaged by HST and study a subset of 2000 galaxies at z<0.3 to elucidate the morphological transformation associated with star formation quenching.
The HST/SDSS Atlas & Morphological Catalog created by this project will also provide legacy value for a wide variety of studies that would benefit from the
combination of the SDSS's statistical power and the HST's resolving power and sensitivity
Also leading up to the grant, Chandler's paper "Improved GALEX UV Photometry for 700,000 SDSS Galaxies" was just published in the Astrophysical Journal Supplement Series (https://iopscience.iop.org/article/10.3847/1538-4365/ace9de). In this major effort Chander performed model photometry in the UV with the aim of reducing the effects, such as the blending, due to the low resolution of Galaxy Evolution Explorer (GALEX) UV images (5 arcsec).
