RFI excision using a higher order statistics analysis of the power spectrum
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/24
A method of radio frequency interference (RFI) suppression in radio astronomy spectral observations is described based on the analysis of the probability distribution of an instantaneous spectrum.
Deconvolution of window effect in galaxy power spectrum analysis
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
We develop a new method for deconvolving the smearing effect of the survey window in the analysis of the galaxy multipole power spectra from a redshift survey. This method is based on the deconvolutio...
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...
