Autocorrelation Functions, Cosmology and Investigating The CMB Cold Spot
  With EMU-ASKAP Radio Continuum Survey
  Galaxy angular-power spectrum and autocorrelation functions (ACFs) provide
information about the distribution of matter by using galaxy counts as a proxy.
In this study, we are going to estimate autocorrelation angular power spectrum
and angular autocorrelation function for EMU-ASKAP 5 sigma sources and then
compare them with results from NVSS. We will also use SUMSS data to compare ACF
results using Landy-Szalay estimator. EMU-ASKAP will provide excellent
opportunity to observe universe with high sensitivity and is likely going to
observe millions of high redshift sources which will help in studying the
clustering of the large scale structures, constraining cosmological parameters
and exploring mysteries like the existence of a cosmic cold spot or the CMB
cold spot as observed by both Planck and WMAP probes. We will discuss some
possible ways, the CMB cold spot puzzle can be explored further by using the
galaxy clustering, integral source count and galaxy bias analysis with a highly
sensitive survey like EMU-ASKAP.
