Little Dwarf Galaxies Survive within Bigger Dwarfs: Why Some Dwarfs Go Dark and Others Stay Luminous
The Large Magellanic Cloud (LMC) was the largest galaxy in a group of galaxies that entered the Milky Way (MW) system at late times. Seven of the 11 brightest dwarf galaxies of the MW may have been part of this system. The association of dwarfs with the plane of the LMCs orbit has been used to argue that they are formed from tidal debris from LMC and SMC (Kroupa et al. 2005). Instead, we find t...
متن کاملThe spatial distribution of the Milky Way and Andromeda satellite galaxies
There are two fundamentally different physical origins of faint satellite galaxies: cosmological sub-structures that contain shining baryons and the fragmentation of gas-rich tidal arms thrown out from interacting galaxies during hierarchical structure formation. The latter tidal-dwarf galaxies (TDG) may form populations with correlated orbital angular momenta about their host galaxies. The exi...
متن کاملThe mass of dwarf spheroidal galaxies and the missing satellite problem
We present the results from a suite of N-body simulations of the tidal stripping of twocomponent dwarf galaxies comprising some stars and dark matter. We show that recent kinematic data from the local group dwarf spheroidal (dSph) galaxies suggests that dSph galaxies must be sufficiently massive (10 − 1010M⊙) that tidal stripping is of little importance for the stars. We discuss the implication...
متن کاملPulsating red giant and supergiant stars in the Local Group dwarf galaxy Andromeda I
We have conducted an optical long-term monitoring survey of the majority of dwarf galaxies in the Local Group, with the Isaac Newton Telescope (INT), to identify the long period variable (LPV) stars. LPV stars vary on timescales of months to years, and reach the largest amplitudes of their brightness variations at optical wavelengths, due to the changing temperature. They trace stellar populati...
متن کاملWay dwarf satellites enter the halo as a group ?
The dwarf satellite galaxies in the Local Group are generally considered to be hosted in dark matter subhalos that survived the disruptive processes during infall onto their host halos. It has recently been argued that if the majority of satellites entered the Milky Way halo in a group rather than individually, this could explain the spatial and dynamical peculiarities of its satellite distribu...
