"25 Years after Relict-1 – the First Attempt
to Detect a Cosmic Microwave Background Anisotropy. Criticism of the Relict-1 Results
in Light of COBE and WMAP Data." Skulachev, Dmitri P. (Space Research
Institute of RAS (IKI)) Abstract: A brief review the
first space cosmological experiment Relict-1 is made. The main results are
considered. Up to date, except
of Relict-1, two space CMB experiments: COBE and WMAP were performed. COBE
was launched 6 years after Relict-1. The COBE instrument was much sensitive then
Relict-1 one, but not enough to compare directly the data received from these
two experiments. WMAP was launched
12 years after COBE, and its receivers are extremely sensitive. WMAP data
after 5 years investigations (release v.3 of March, 2008) has a small noise
level at any points over the sky. So, WMAP data may be considered as a rather
exact model of the signal, have been measured by Relict-1, 25 years ago. A published data
concerned with the Relict-1 and COBE disaccord is discussed. For the model-depended
estimation of the CMB anisotropy Relict-1, COBE, and WMAP data are compared. The Relict-1 data,
in spite of a relative high noise level, may be used in correlation procedure
with WMAP data. The result of the analysis is produced. In addition, a
correctness of Relict-1 operation characteristic choice is considered. |
