Interstellar dust grains are responsible for modifying the spectral energy distribution
(SED) of galaxies, both absorbing starlight at UV and optical wavelengths and con-verting this energy into ther...
Improving the Estimation of Star formation Rates and Stellar Population Ages of High-redshift Galaxies from Broadband Photometry
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We explore methods to improve the estimates of star formation rates and mean stellar population ages from broadband photometry of high redshift star-forming galaxies. We use synthetic spectral templat...
Improving Galactic Center Astrometry by Reducing the Effects of Geometric Distortion
Galaxy Astrophysics (astro-ph.GA)
2010/12/22
We present significantly improved proper motion measurements of the Milky Way's central stellar cluster. These improvements are made possible by refining our astrometric reference frame with a new geo...
