SUMMARY:Anthony Pullen (NYU) Title: Revealing CII Emission with LSS Cross-correlations
DESCRIPTION:Abstract:\n\nIn this talk\, I will present our joint measurement of cosmic infrared background (CIB) and CII line emission from large scales at redshift z=2.5 using an MCMC analysis of cross-correlations of the 3 high-frequency Planck bands with both SDSS-III quasars at z=2-3.2 and SDSS-III CMASS galaxies at z=0.43-0.7.  The CII emission is expected to correlate with the quasars and appear in the Planck 545 GHz band\, while the other cross-correlations are assumed to mostly be attributable to CIB-LSS correlations.  We report an excess emission inconsistent with the null result at 95% confidence\, with an intensity value favoring the higher range of CII models.  I will also forecast potential CII intensity constraints from Planck cross-correlated with DESI quasars.
