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…
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…
Improving Photometric Redshifts using GALEX Observations for the SDSS Stripe 82 and the Next Generation of SZ Cluster Surveys
Michael D. Niemack, Raul Jimenez, Licia Verde +3
Four large-area Sunyaev-Zeldovich (SZ) experiments -- APEX-SZ, SPT, ACT, and Planck -- promise to detect clusters of galaxies through the distortion of Cosmic Microwave Background…
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…
Loss of star forming gas in SDSS galaxies
F. Calura, R. Jimenez, B. Panter +2
Using the star formation rates from the SDSS galaxy sample, extracted using the MOPED algorithm, and the empirical Kennicutt law relating star formation rate to gas density, we cal…
Recovering galaxy star formation and metallicity histories from spectra using VESPA
Rita Tojeiro, Alan F. Heavens, Raul Jimenez +1
We introduce VErsatile SPectral Analysis (VESPA): a new method which aims to recover robust star formation and metallicity histories from galactic spectra. VESPA uses the full spec…
