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…
Extragalactic Constraints on the Initial Mass Function
Stephen M. Wilkins, Andrew M. Hopkins, Neil Trentham +1
The local stellar mass density is observed to be significantly lower than the value obtained from integrating the cosmic star formation history (SFH), assuming that all the stars f…
Evidence for short-lived SN Ia progenitors
Eric Aubourg, Rita Tojeiro, Raul Jimenez +3
We use the VESPA algorithm and spectra from the Sloan Digital Sky Survey to investigate the star formation history of the host galaxies of 257 Type Ia supernovae. We find 5 evid…
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…
Non-Gaussianity in the WMAP data using the peak-peak correlation function
R. Tojeiro, P. G. Castro, A. F. Heavens +1
We present a search for non-Gaussianity in the WMAP first-year data using the two-point correlation function of maxima and minima in the temperature map. We find evidence for non-G…
