The Caltech Core-Collapse Program (CCCP)

1
The Caltech Core-Collapse Program (CCCP)

• Study a complete sample of core-collapse SNe
  using Caltech telescopes at Palomar
• 200 telescope (23 nights _at_2004B and 2005A,
  Optical spectroscopy and IR photometry) and the
  robotic Palomar 60 telescope (Optical
  photometry)
• Mutual support Berkeley Group (Filippenko et al)
  ANU (Salvo, Schmidt) Wise Observatory (Maoz,
  Ofek, Poznanski)

Motivation

• A complete sample of core-collapse SNe every
  young (lt30 days after last non-detection at
  discovery) core-collapse (via spectroscopy or
  phototyping) SN, above 18.5 mag, visible from
  Palomar
• Characterize the CC SN population
• Test viability of SNe II-P for cosmology
• Provide well studied sample of Ib/c SNe as
  comparison for high-z GRB studies

4
Related/Integrated projectsat Caltech

• A comprehensive study of SNe Ib/c in the radio,
  optical and X-ray (Soderberg, Kulkarni, et al.)
• Effort to test the cosmological utility of SNe
  II-P (Ellis, Sullivan, Nugent, Baltay, Leonard et
  al.)
• Spectropolarimetry (see Poster by Leonard for
  exciting result!)

5
Preliminary results

• 20 SNe observed so far (12 II, 8 Ib/c) so
  expected total is 50, as expected
• Early photometry from P60
• High S/N spectra from P200 and Keck
• Sparse (but high S/N and very accurate) IR
  photometry

CCCP and you

• CCCP science is damaged by weather. We seek
  community help in securing continuous coverage
  throughout the year.
• CCCP will support time critical studies of SNe
  and GRBs, e.g., the large HST SN Ia UV campaign
  (PI Filippenko), more ?
