Distribution probability of galaxies in Local Group
نویسندگان
چکیده
The evolution of galaxies is a very important topic for understanding the Universe, and this results in that are not evenly distributed space. probability distribution space can be computed according to probabilistic models. Although has been studied from various angles, yet with respect their positions over time. Of galaxies, Local Group have more thoroughly. In study, we probabilities Group, i.e. at present previous positions, an even show extremely small chance distribute evenly, increases past present. implication accelerating expansion universe increasing probabilistically probable event.

The Luminosity Distribution of Local Group Galaxies
From a rediscussion of Local Group membership, and of distances to individual galaxies, we obtain MV values for 35 probable and possible Local Group members. The luminosity function of these objects is well fitted by a Schechter function with faint end slope α = −1.1 ± 0.1. The probability that the luminosity distribution of the Local Group is a single Schechter function with α steeper than −1....
متن کاملMetallicity Distribution Functions of Four Local Group Dwarf Galaxies
We present stellar metallicities in Leo I, Leo II, IC 1613, and Phoenix dwarf galaxies derived from medium (F390M) and broad (F555W, F814W) band photometry using the Wide Field Camera 3 instrument on board the Hubble Space Telescope. We measured metallicity distribution functions (MDFs) in two ways, (1) matching stars to isochrones in color–color diagrams and (2) solving for the best linear com...
متن کاملDistances to Local Group Galaxies
Distances to galaxies in the Local Group are reviewed. In particular, the distance to the Large Magellanic Cloud is found to be (m−M)0 = 18.52 ± 0.10, corresponding to 50, 600± 2, 400 pc. The importance of M31 as an analog of the galaxies observed at greater distances is stressed, while the variety of star formation and chemical enrichment histories displayed by Local Group galaxies allows crit...
متن کاملGiant Molecular Clouds in Local Group Galaxies
We present the first comparative study of extragalactic GMCs using complete data sets for entire galaxies and a uniform set of reduction and analysis techniques. We present results based on CO observations for the LMC, SMC, M33, M31, IC10 and the nucleus of M64, and make comparisons with archival Milky Way observations. Our sample includes large spirals and dwarf irregulars with metallicities t...
متن کاملReionization of the Local Group of Galaxies
We present the first detailed structure formation and radiative transfer simulations of the reionization history of our cosmic neighbourhood. To this end, we follow the formation of the Local Group of galaxies and nearby clusters by means of constrained simulations, which use the available observational constraints to construct a representation of those structures which reproduces their actual ...
