Galaxy motions in the Bootes strip
Igor D. Karachentsev, Valentina E. Karachentseva, Olga G. Nasonova
We explore the structure and kinematics of a dispersed filament of galaxies residing between the Local Void and the Virgo cluster. For such purpose, we consider a sample of 361 gal…
Abundance of Field Galaxies
Anatoly Klypin, Igor Karachentsev, Dmitry Makarov +1
We present new measurements of the abundance of galaxies with a given circular velocity in the Local Volume: a region centered on the Milky Way Galaxy and extending to distance 10M…
Intense look at Virgo Southern Extension
Igor D. Karachentsev, Olga G. Nasonova
We collected data on radial velocities and distances of galaxies to elucidate structure and kinematics of the filament attached to the Virgo cluster from south. In the region RA =…
Anatomy of Ursa Majoris
I. D. Karachentsev, O. G. Nasonova, H. M. Courtois
A nearby friable cloud in Ursa Majoris contains 270 galaxies with radial velocities 500 < VLG < 1500 km s^-1 inside the area of RA= [11h; 13h] and DEC= [+40deg; +60deg]. At present…
Fast motions of galaxies in the Coma I cloud: a case of Dark Attractor?
Igor D. Karachentsev, Olga G. Nasonova, Helene M. Courtois
We notice that nearby galaxies having high negative peculiar velocities are distributed over the sky very inhomogeneously. A part of this anisotropy is caused by the "Local Velocit…
Hubble flow around Fornax cluster of galaxies
Olga G. Nasonova, José A. de Freitas Pacheco, Igor D. Karachentsev
Aims. This work aims to provide a new mass estimate for the Fornax cluster and the Fornax-Eridanus complex, avoiding methods like the virial or fits of X-ray emission profile, whic…
On the kinematics of the Local cosmic void
Olga Nasonova, Igor Karachentsev
We collected the existing data on the distances and radial velocities of galaxies around the Local Void in the Aquila/Hercules to examine the peculiar velocity field induced by its…
Blueshifted galaxies in the Virgo Cluster
I. D. Karachentsev, O. G. Nasonova
We examine a sample of 65 galaxies in the Virgo cluster with negative radial velocities relative to the Local Group. Some features of this sample are pointed out. All of these obje…
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…
The observed infall of galaxies towards the Virgo cluster
I. D. Karachentsev, O. G. Nasonova
We examine the velocity field of galaxies around the Virgo cluster induced by its overdensity. A sample of 1792 galaxies with distances from the Tip of the Red Giant Branch, the Ce…
