Causal limit of neutron star maximum mass in f(R) gravity in view of GW190814 by Astashenok, A.V., Capozziello, S., Odintsov, S.D., Oikonomou, V.K.

“…We investigate the causal limit of maximum mass for stars in the framework of f(R) gravity. We choose a causal equation of state, with variable speed of sound,…”

The unified history of the viscous accelerating universe and phase transitions by Astashenok, A.V., Odintsov, S.D., Tepliakov, A.S.

“…We propose the unified description of the early acceleration (cosmological inflation) and the present epoch of so called “dark energy”. The inflation can be…”

An infrared divergence in the cosmological measure theory and the anthropic reasoning by Yurov, A. V., Yurov, V. A., Astashenok, A. V., Shpilevoi, A. A.

“…An anthropic principle has made it possible to answer the difficult question of why the observable value of cosmological constant ( Λ ∼10 −47  GeV 4 ) is so…”
