Virial estimator for dark energy
A. D. Chernin, P. Teerikorpi, M. J. Valtonen +3
A new estimator of the local density of dark energy is suggested which comes from the virial theorem for non-relativistic gravitating systems embedded in the uniform dark energy ba…
The NGC 1023 Galaxy Group: An Anti-Hubble Flow?
A. D. Chernin
We discuss recently published data indicating that the nearby galaxy group NGC 1023 includes an inner virialized quasi-stationary component and an outer component comprising a flow…
Dark energy domination in the Virgocentric flow
A. D. Chernin, I. D. Karachentsev, O. G. Nasonova +5
The standard \LambdaCDM cosmological model implies that all celestial bodies are embedded in a perfectly uniform dark energy background, represented by Einstein's cosmological cons…
Dark energy and the mass of the Local Group
A. D. Chernin, P. Teerikorpi, M. J. Valtonen +3
Dark energy must be taken into account to estimate more reliably the amount of dark matter and how it is distributed in the local universe. For systems several Mpc across like the…
Local dark energy: HST evidence from the vicinity of the M 81/M 82 galaxy group
A. D. Chernin, I. D. Karachentsev, O. G. Kashibadze +5
The Hubble Space Telescope observations of the nearby galaxy group M 81/M 82 and its vicinity indicate that the expansion outflow around the group is dominated by the antigravity o…
Detection of dark energy near the Local Group with the Hubble Space Telescope
A. D. Chernin, I. D. Karachentsev, P. Teerikorpi +7
We report the detection of dark energy near the Milky Way made with precision observations of the local Hubble flow of expansion. We estimate the local density of dark energy and f…
Local dark energy: HST evidence from the expansion flow around Cen A/M83 galaxy group
A. D. Chernin, I. D. Karachentsev, D. I. Makarov +5
A structure with a massive group in its center and a cool expansion outflow outside is studied around the Cen A galaxy with the use of the Hubble Space Telescope observations. It i…
The very local Hubble flow: Simulating transition from chaos to order
A. D. Chernin, I. D. Karachentsev, M. J. Valtonen +3
The physical nature of the very local (<3 Mpc) Hubble flow is studied on the basis of the recent high precision observations in the Local Volume. A model including both analytical…
The very local Hubble flow: computer simulations of dynamical history
A. D. Chernin, I. D. Karachentsev, M. J. Valtonen +3
The phenomenon of the very local ( Mpc) Hubble flow is studied on the basis of the data of recent precision observations. A set of computer simulations is performed to trace…
