Systematics in Aggregated Neutrino Fluxes and Flavor Ratios from Gamma-Ray Bursts
Systematics Aggregated Neutrino Fluxes Flavor Ratios Gamma-Ray Bursts
2011/10/20
Gamma-ray burst analyses at neutrino telescopes are typically based on diffuse or stacked (i.e., aggregated) neutrino fluxes, because the number of events expected from a single burst is small. The ag...
Completeness III: identifying characteristic systematics and evolution in galaxy redshift surveys
Cosmology: methods: data analysis – methods:redshift surveys – galaxies: large-scale structure of Universe
2011/9/28
This paper continues our development of non-parametric tests for analysing the completeness in apparent magnitude of magnitude-redshift surveys. The purpose of this third and final paper in our comple...
Impact of Instrumental Systematics on the CMB Bispectrum
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We study the effects of instrumental systematics on the estimation of primordial non-Gaussianity using the cosmic microwave background (CMB) bispectrum from both the temperature and the polarization a...
Anomalous parity asymmetry of WMAP power spectrum data at low multpoles: is it cosmological or systematics?
parity asymmetry cosmological WMAP power spectrum data
2010/3/8
We have investigated the odd-parity preference of the WMAP 7 year power spectrum. Our investigation shows parity asymmetry of the WMAP data (2<= l <=22) is anomalous at 4-in-1000 level. We also find i...
