Galaxy Spectra assignment
  • The textbook is rather weak when it comes to observational properties like spectra – as budding young observers you need to know more!
  • Find and download the galaxy spectra templates of Kinney et al. (1996) – and read the paper!
  • Find and download the spectral synthesis population models of Bruzual and Charlot.
  • “Fit” the elliptical template and one spiral galaxy.
  • Show some plots indicating how broad-band colors change with redshift assuming not evolution (up to z=2).
  • Write up your results like you would for publication with clarity, citations, etc.

MAP!
  • NASA press conference:
  • Ho=71
    T=13.7 Gyr
    Omega=1.00
    Omega_baryon=0.04
    Omega_dm=0.23
    Omega_lambda=0.73

    First stars at z~16

MAP!
  • We’re going to devote this class to MAP.  We’ll go through (begin. and int.) Wayne Hu webpages Mike Pierce suggested:
  • http://background.uchicago.edu/~whu/physics/physics.html
  •  Advanced Mathematical description is in Chapter 15 of Longair – we’re not quite ready for that yet.


  • HW: Technical paper Bennett et al. 2003
