We provide a correlation analysis of various signatures associated with traces of the decay of dark matter and galaxy spatial distribution, which play an important role in the context of current and future observations and cosmological constraints. Attention is paid to the constraints that can be obtained for decaying sterile neutrinos when analyzing observations in the context of the Spectr-Roentegn-Gamma (SRG) mission. We examine the correlation spectra of these signatures, which can be obtained both for the eROSITA telescope and for the ART-XC telescope, and investigate the applicability of the multipole approximation.
