The primordial deuterium abundance: subDLA system at $z_{abs} = 2.437$ towards the QSO J1444+2919

S. A. Balashev, E. O. Zavarygin, A. V. Ivanchik +2

We report a new detection of neutral deuterium in the sub Damped Lyman Alpha system with low metallicity [O/H]\,=\, $- 2.042 \pm 0.005$ at $z_{abs} = 2.437$ towards QSO~J\,1444 $+$ 2…

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…
