THE SCALAR PERTURBATION SPECTRAL INDEX ns: WMAP SENSITIVITY TO UNRESOLVED POINT SOURCES
Precision measurement of the scalar perturbation spectral index, ns, from the Wilkinson Microwave Anisotropy Probe (WMAP) temperature angular power spectrum requires the subtraction of unresolved point-source power. Here we reconsider this issue, attempting to resolve inconsistencies found in the literature. First, we note a peculiarity in the WMAP temperature likelihood’s response to the sourc...
متن کاملA statistical test of emission from unresolved point sources
We describe a simple test of the spatial uniformity of an ensemble of discrete events. Given an estimate for the point source luminosity function and an instrumental point spread function (PSF), a robust upper bound on the fractional point source contribution to a diffuse signal can be found. We verify with Monte Carlo tests that the statistic is superior to the two-point correlation function f...
متن کاملInflationary potentials yielding constant scalar perturbation spectral indices
Inflation, a cornerstone of the modern framework for understanding the early universe @1,2#, predicts the initial conditions for the formation of structure and the cosmic microwave background ~CMB! anisotropies. During inflation, the primordial scalar ~density! and tensor ~gravitational wave! perturbations generated by quantum fluctuations are redshifted beyond the Hubble radius, becoming froze...
متن کاملSe p 20 06 Contribution of unresolved point sources to the galactic diffuse emission
The detection by the HESS atmospheric Cherenkov telescope of fifteen new sources from the Galactic plane makes it possible to estimate the contribution of unresolved point sources like those detected by HESS to the diffuse Galactic emission measured by EGRET and recently at higher energies by the Milagro Collaboration. Assuming that HESS sources have all the same intrinsic lumi-nosity, the cont...
متن کاملEvidence for Unresolved γ-Ray Point Sources in the Inner Galaxy.
We present a new method to characterize unresolved point sources (PSs) generalizing traditional template fits to account for non-Poissonian photon statistics. We apply this method to Fermi Large Area Telescope γ-ray data to characterize PS populations at high latitudes and in the Inner Galaxy. We find that PSs (resolved and unresolved) account for ∼50% of the total extragalactic γ-ray backgroun...
