Measuring the galaxy power spectrum with multiresolution decomposition -- IV. redshift distortion
Xiao-Hu Yang, Long-Long Feng, Yao-Quan Chu +1
In this paper, we develop a theory of redshift distortion of the galaxy power spectrum in the discrete wavelet transform (DWT) representation. Because the DWT power spectrum is dep…
Measuring the galaxy power spectrum with multiresolution decomposition -- III. velocity field analysis
Xiao-Hu Yang, Long-Long Feng, Yao-Quan Chu +1
In this paper, we develop the method of analyzing the velocity field of cosmic matter with a multiresolution decomposition. This is necessary in calculating the redshift distortion…
Measuring the galaxy power spectrum with multiresolution decomposition -- II. diagonal and off-diagonal power spectra of the LCRS galaxies
Xiao-Hu Yang, Long-Long Feng, Yao-Quan Chu +1
The power spectrum estimator based on the discrete wavelet transform (DWT) for 3-dimensional samples has been studied. The DWT estimator for multi-dimensional samples provides two…
X-ray Emitting QSOs Ejected from Arp 220
H. C. Arp, E. M. Burbidge, Y. Chu
Four compact ROSAT X-ray sources very close to the nearby ultraluminous infrared galaxy Arp 220 (IC 4553) have been identified as medium-redshift QSOs. The closest pair lying symme…
