A public catalogue of stellar masses, star formation and metallicity histories and dust content from the Sloan Digital Sky Survey using VESPA

Rita Tojeiro, Stephen Wilkins, Alan F. Heavens +2

We applied the VESPA algorithm to the Sloan Digital Sky Survey final data release of the Main Galaxies and Luminous Red Galaxies samples. The result is a catalogue of stellar masse…

Environment and the cosmic evolution of star formation

Ravi K. Sheth, Raul Jimenez, Ben Panter +1

We present a mark correlation analysis of the galaxies in the Sloan Digital Sky Survey using weights provided by MOPED. The large size of the sample permits statistically significa…

The role of spin in the formation and evolution of galaxies

Zachory K. Berta, Raul Jimenez, Alan F. Heavens +1

Using the SDSS spectroscopic sample, we estimate the dark matter halo spin parameter lambda for ~53,000 disk galaxies for which MOPED star formation histories are available. We inv…

Physical Classification of Galaxies with MOPED/VESPA

Raul Jimenez, Alan F. Heavens, Ben Panter +1

The availability of high-quality spectra for a large number of galaxies in the SDSS survey allows for a more sophisticated extraction of information about their stellar populations…

Stellar atmosphere parameters with MAx, a MAssive compression of x^2 for spectral fitting

Paula Jofré, Ben Panter, Camilla Juul Hansen +1

MAx is a new tool to estimate parameters from stellar spectra. It is based on the maximum likelihood method, with the likelihood compressed in a way that the information stored in…

The star formation histories of galaxies in the Sloan Digital Sky Survey

Ben Panter, Raul Jimenez, Alan F. Heavens +1

We present the results of a MOPED analysis of ~3 x 10^5 galaxy spectra from the Sloan Digital Sky Survey Data Release Three (SDSS DR3), with a number of improvements in data, model…
