Planets in the Early Universe
Yu. A. Shchekinov, M. Safonova, J. Murthy
Several planets have recently been discovered around old metal-poor stars, implying that these planets are also old, formed in the early Universe. The canonical theory suggests tha…
Evolution of the First Supernovae in Protogalaxies: Dynamics of Mixing of Heavy Elements
E. O. Vasiliev, E. I. Vorobyov, E. E. Matvienko +2
The paper considers the evolution of the supernova envelopes produced by Population III stars with masses of located in non-rotating protogalaxies with mas…
Instabilities in the Ionization Zones Around the First Stars
E. O. Vasiliev, E. I. Vorobyov, A. O. Razoumov +1
We consider the evolution of the ionization zone around Population III stars with in protogalaxies with at redshifts , assumin…
Observational Manifestations of the First Protogalaxies in the 21 cm Line
E. O. Vasiliev, Yu. A. Shchekinov
The absorption properties of the first low-mass protogalaxies (mini-halos) forming at high redshifts in the 21-cm line of atomic hydrogen are considered. The absorption properties…
Particle decay and 21 cm absorption from first minihaloes
E. O. Vasiliev, Yu. A. Shchekinov
We consider the influence of decaying dark matter (DM) particles on the characteristics of 21 cm absorption in spectra of distant radio-loud sources - "21 cm forest" - from minihal…
