SUBCLASSES OF TYPE Ia SUPERNOVAE AS THE ORIGIN OF [α/Fe] RATIOS IN DWARF SPHEROIDAL GALAXIES [PDF]

, 2015
Recent extensive observations of Type Ia Supernovae (SNe Ia) have revealed the existence of a diversity of SNe Ia, including SNe Iax. We introduce two possible channels in the single degenerate scenario: (1) double detonations in sub-Chandrasekhar (Ch ...

Ultradiffuse Galaxies—A Distinct Population? Dwarf Galaxies in the Coma Cluster and A262 from Deep u′–g′–r′ Wendelstein Imaging Data

The Astrophysical Journal Supplement Series
In this study, we compare the structural parameters of ultradiffuse galaxies (UDGs) to those of other dwarf galaxies and investigate whether UDGs form a distinct population.

Origin of structural and kinematical properties of the Small Magellanic Cloud

, 2009
We investigate structural, kinematical, and chemical properties of stars and gas in the Small Magellanic Cloud (SMC) interacting with the Large Magellanic Cloud (LMC) and the Galaxy based on a series of self-consistent chemodynamical simulations.

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.

Disentangling γ − β: The Fourth-order Velocity Moments Based on Spherical Jeans Analysis

The Astrophysical Journal
Distinguishing a core and a cusp within dark matter halos is complexified by the existence of mass-anisotropy degeneracy, where various combinations of velocity anisotropy ( β ) and inner density slope ( γ ) yield similar observational signatures.
