A search for cosmological anisotropy using the Lyman alpha forest from SDSS quasar spectra
E. O. Zavarygin, J. K. Webb
The Cosmological Principle, the combined assumptions of cosmological isotropy and homogeneity, underpins the standard model of Big Bang cosmology with which we interpret astronomic…

Primordial deuterium abundance at z=2.504 towards Q1009+2956
E. O. Zavarygin, J. K. Webb, S. Riemer-Sørensen +1
The z_abs = 2.504 Lyman Limit absorption system (LLS) towards Q1009+2956 has previously been used to estimate the primordial deuterium abundance. Since the initial measurement by B…

Variation of the baryon-to-photon ratio due to decay of dark matter particles
E. O. Zavarygin, A. V. Ivanchik
The influence of dark matter particle decay on the baryon-to-photon ratio has been studied for different cosmological epochs. We consider different parameter values of dark matter…
