Hubble's (1936, p. 125) view that the Local Group (LG) is “a typical, small group of nebulae which is isolated in the general field” is confirmed by modern data. The total number of certain and probable Group members presently stands at 35. The half-mass radius of the Local Group is found to be $$R_{\rm h}\approx 350$$ kpc. The zero-velocity surface, which separates the Local Group from the field that is expanding with the Hubble flow, has a radius $$R_{\rm o} = 1.18\pm 0.15$$ Mpc. The total… Expand

Updated Information on the Local Group
The present note updates the information published in my recent monograph on \underline{The Galaxies of the Local Group}. Highlights include (1) the addition of the newly discovered Cetus dwarfExpand
Balancing mass and momentum in the Local Group
• Physics
• 2014
In the rest frame of the Local Group (LG), the total momentum of the Milky Way (MW) and Andromeda (M31) should balance to zero. We use this fact to constrain new solutions for the solar motion withExpand
Red giant branch stars as probes of stellar populations. II. Properties of the newly discovered globular cluster GLIMPSE-C01
• Physics
• 2005
Deep near infrared photometry of the newly discovered Galactic globular Cluster GLIMPSE-C01 is reported. We derived for the first time the metal abundance of this object from the slope of the RGB:Expand
The grouping, merging and survival of subhaloes in the simulated Local Group
We use a simulation performed within the Constrained Local Universe Simulation (CLUES) project to study a realistic Local Group (LG)-like object. We employ this group as a numerical laboratory forExpand
On the Spin Bias of Satellite Galaxies in the Local Group-like Environment
• Physics
• 2013
We utilize the Millennium-II simulation databases to study the spin bias of dark subhalos in the Local Group-like systems which have two prominent satellites with comparable masses. Selecting theExpand
Planar distribution of the galaxies in the Local Group: a statistical and dynamical analysis
Aims. Basing on the projected distribution of the galaxies in the Local Group, Sawa & Fujimoto found that they all seem to distribute on a rather thin plane containing the two mayor local galaxies ofExpand
Proper Motions of Dwarf Spheroidal Galaxies from Hubble Space Telescope Imaging. IV: Measurement for Sculptor
The measured proper motion of Fornax, expressed in the equatorial coordinate system, is $(\mu_{\alpha},\mu_{\delta})=(47.6\pm 4.6,-36.0\pm 4.1)$ mas century$^{-1}$. This proper motion is a weightedExpand
Did globular clusters reionize the Universe
A problem still unsolved in cosmology is the identification of the sources of radiation able to reionize H I in the intergalactic medium (IGM) by z∼6. Theoretical work and observations seem toExpand
The Local Hubble flow: A Manifestation of dark energy
• Physics
• 2000
Our local environment at $r<10$ Mpc expands linearly and smoothly, as if ruled by a uniform matter distribution, while observations show the very clumpy local universe. This is a long standing enigmaExpand
GAS-RICH DWARF SPHEROIDALS
• Physics
• 2000
We present evidence that 10 of the 21 dwarf spheroidal galaxies (dSph and dSph/dIrr) in the Local Group are associated with large reservoirs of atomic gas, reservoirs that are, in some cases, largerExpand
