Science Goals

  • Improve statistical constraints on dark energy

    • 2x improvement for SNLS, Essence, SNAP

  • Improve systematics uncertainties on dark energy

    • Better calibration of SN properties

    • Span wide range of physical & empirical parameters

    • Constrain SN physics

  • 300 Type Ia SNe

    • in the nearby smooth Hubble flow

    • with many-epoch spectrophotometry

SNfactory Management


SNfactory Schedule - Past


Past dominated by SuperNova Integral Field Spectrograph construction


SNfactory Schedule - Coming Up


More on UH Telescope Future

  • PanSTARRS wants to use UH 2.2-m site

  • SNIFS operations guarenteed through April 2007

  • Director’s invitation to propose accelerated program

  • Tenative: propose accelerated program once at steady-state

2005

Summer


More on UH Telescope Future

  • PanSTARRS wants to use UH 2.2-m site

  • SNIFS operations guarenteed through April 2007

  • Invitation to propose accelerated program

  • Tenative: propose accelerated program once at steady-state

  • Tenative: Exploring other telescope options, e.g. Kitt Peak 2.1-m for SNIFS and/or NIR imaging


More on Palomar Telescope

  • QUEST II camera built by Yale and Indiana universities

  • 50% time drift-scan (QUEST/CIT); 50% point & track (NEAT)

  • NEAT MoU annually renewed (between JPL and LBNL Physics)

  • QUEST leader, Baltay, has joined SNfactory


SNfactory Budget - Moore Grant

  • Moore grant is $2.4M USD over three years

  • Intent is to enhance usefulness of SNfactory database

  • Not intended to fund existing operations

  • Funding for 3 postdocs and 2 software engineers

  • Deliverables:

    • Spectral database w/ full traceability

    • Scheduler


Publications Plan

  • Instrument paper

  • Spectroscopy of special SNfactory+HST+NIR supernovae

  • Calibration paper

  • Annual spectral analysis/heterogeneity paper

  • Annual cosmology paper (low+high redshift SNe)

  • Additional papers on special SNe

  • Rates paper
