Star Formation and Metallicity History of the SDSS galaxy survey: unlocking the fossil record
Benjamin Panter, Alan F. Heavens, Raul Jimenez
Using MOPED we determine non-parametrically the star-formation and metallicity history of over 37,000 high-quality galaxy spectra from the Sloan Digital Sky Survey (SDSS) early dat…
Baryonic Conversion Tree: The global assembly of stars and dark matter in galaxies from the SDSS
Raul Jimenez, Benjamin Panter, Alan Heavens +1
Using the spectroscopic sample of the SDSS DR1 we measure how gas was transformed into stars as a function of time and stellar mass: the baryonic conversion tree (BCT). There is a…
The Cosmic Evolution of Metallicity from the SDSS Fossil Record
Benjamin Panter, Raul Jimenez, Alan F. Heavens +1
We present the time evolution of the stellar metallicity for SDSS galaxies, a sample that spans five orders of magnitude in stellar mass (10^7 - 10^{12} Msun). Assuming the BC03 st…
The Complete Star Formation History of the Universe
Alan Heavens, Benjamin Panter, Raul Jimenez +1
The determination of the star-formation history of the Universe is a key goal of modern cosmology, as it is crucial to our understanding of how structure in the Universe forms and…
