Session 52 - Source Surveys and CMB Radiation.
Display session, Wednesday, June 10
Atlas Ballroom,
We have correlated infrared fluxes in the IRAS 1.2 Jy Survey Redshift Data (Infrared Astronomical Satellite), (Fisher et al., 1997) with radio fluxes in the NVSS Source Catalog (NRAO/VLA Sky Survey), (Condon et al., 1996) in order to see whether the radio absorption by the intergalactic medium (IGM) claimed by Big Bang critic Eric Lerner actually exists. The reason that this is important is that the conventional interpretation of the cosmic background radiation (CBR) as a relic of the Big Bang assumes that the intergalactic medium (IGM) is highly transparent to radio frequency radiation. We have chosen infrared fluxes for 178 galaxies selected randomly from 3920 available sources from the 1.2 Jy IRAS catalog. The Infrared flux interval is from 1.2 Jy to 10 Jy. Their corresponding radio fluxes were taken from the NVSS source catalog. The analysis of the plot of these two luminosities shows a non-linear correlation in which the radio luminosity for a given IR luminosity is independent of distance. When a redshift dependent term is added to this correlation, the improvement in the fit is statistically insignificant.
