γ-ray and ν Searches for Dark-Matter Subhalos in the Milky Way with a Baryonic Potential
Galaxies, 2019 The distribution of dark-matter (DM) subhalos in our galaxy remains disputed, leading to varying γ -ray and ν flux predictions from their annihilation or decay.

Variable Stars in Dwarf Spheroidal Galaxies [PDF]
International Astronomical Union Colloquium, 1973 Interest in dwarf spheroidal galaxies is motivated by a number of reasons; an important one on the occasion of this colloquium is the abundance of variable stars. The theory of stellar evolution and stellar pulsations is now able to predict from theoretical considerations characteristic properties of variable stars in the colour-magnitude diagram (Iben,

The evolution of the photometric properties of Local Group dwarf spheroidal galaxies
, 2008 We investigate the present-day photometric properties of the dwarf spheroidal galaxies in the Local Group. From the analysis of their integrated colours, we consider a possible link between dwarf spheroidals and giant ellipticals.

Dwarf spheroidal galaxies and the mass of the neutrino
The Astrophysical Journal, 1992 It is argued that neutrinos cannot provide the missing mass in Draco and Ursa Minor, since for reasonable neutrino mass (m v ∼ 30 eV) phase-space limits would then require very large core radii (∼ 10 kpc) and masses (∼ 4 × 10 11 M ⊙ ) for these dwarfs, which would make their dynamical friction decay times in the Galactic halo significantly shorter ...

From Supermassive Black Holes to Dwarf Elliptical Nuclei: a Mass Continuum
, 2006 Considerable evidence suggests that supermassive black holes reside at the centers of massive galactic bulges. At a lower galactic mass range, many dwarf galaxies contain extremely compact nuclei that structurally resemble massive globular clusters.

The mass content of the Sculptor dwarf spheroidal galaxy
, 2008 We present a new determination of the mass content of the Sculptor dwarf spheroidal galaxy, based on a novel approach which takes into account the two distinct stellar populations present in this galaxy.

Astrophysical site(s) of r-process elements in galactic chemodynamical evolution model
EPJ Web of Conferences, 2016 Astrophysical site(s) of rapid neutron-capture process (r-process) is (are) not identified yet. Although core-collapse supernovae have been regarded as one of the possible candidates of the astrophysical site of r-process, nucleosynthesis studies suggest

Scaling Laws for Dark Matter Halos in Late-Type and Dwarf Spheroidal Galaxies [PDF]
, 2004 Maximum disk mass models fitted to galaxy rotation curves are used to show that dark matter (DM) halos in late-type and dwarf spheroidal (dSph) galaxies satisfy well defined scaling laws.
