Description

The angular power spectra due to the Sunyaev-Zeldovich effect as predicted by four different models (named TBO-1, TBO-2, Battaglia, Shaw) are supplied for the 148 GHZ ACT frequency.

They are all computed for sigma8=0.8, and other cosmological parameters matching the WMAP best-fit LCDM model. Their descriptions are given in the following papers:

  • "Simulations of the Microwave Sky," N. Sehgal et.al (TBO-1) (2010) [eprint arXiv:0908.0540]
  • "Templates for the Sunyaev-Zel'dovich Angular Power Spectrum," H. Trac, P. Bode & J. Ostriker (2010) ( TBO-2) [eprint arXiv:1006.2828]
  • "Impact of Cluster Physics on the Sunyaev-Zel'dovich Power Spectrum," L. Shaw et.al. (2010) (Shaw) [eprint arXiv:1006.1945]
  • "Simulations of the Sunyaev-Zel'dovich Power Spectrum with AGN Feedback," N. Battaglia et.al. (2010) (Battaglia) [eprint arXiv:1003.4256]

The spectra are supplied in a text file with two columns:
-The multipole moment l
-The 148GHz spectrum in μK2, l(l+1)C_l/2pi

There are six files
-'cl_tsz_148_tbo1.dat' is the tSZ predicted by TBO-1
-'cl_tsz_148_tbo2.dat' is the tSZ predicted by TBO-2
-'cl_tsz_148_batt.dat' is the tSZ predicted by Battaglia
-'cl_tsz_148_shaw.dat' is the tSZ predicted by Shaw
-'cl_ksz_148_tbo.dat' is the kSZ predicted by TBO-1
-'cl_tksz_148_tbo1.dat' is the combined tSZ+kSZ signal predicted by TBO-1
