Revisiting the optical depth of spiral galaxies using the Tully-Fisher B relation
E. Kankare, M. Hanski, G. Theureau +1
Aims. We attempt to determine the optical depth of spiral galaxy disks by a statistical study of new Tully-Fisher data from the ongoing KLUN+ survey, and to clarify the difference…
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…
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…
Non-Friedmann cosmology for the Local Universe, significance of the universal Hubble constant and short-distance indicators of dark energy
Arthur D. Chernin, Pekka Teerikorpi, Yurij V. Baryshev
Basing on the increasing evidence for the cosmological relevance of the local Hubble flow, we consider a simple analytical cosmological model for the Local Universe. This is a non-…
The distance scale and Eddington efficiency of luminous quasars
P. Teerikorpi
The relation between the central mass and quasar luminosity (M_BH \propto L^αFHWM^2) links a given Eddington ratio with a value of H_0, within a cosmology with fixed (Ω_m,Ω_Λ). We…
The quiescent Hubble flow, local dark energy tests, and pairwise velocity dispersion in a universe
Pekka Teerikorpi, Arthur D. Chernin, Yurij V. Baryshev
We review the increasing evidence for the cosmological relevance of the cold local Hubble flow. New observations, N-body simulations and other theoretical arguments are discussed,…
