High-resolution mass models of dwarf galaxies from LITTLE THINGS

1 code implementation • 4 Feb 2015 • Se-Heon Oh, Deidre A. Hunter, Elias Brinks, Bruce G. Elmegreen, Andreas Schruba, Fabian Walter, Michael P. Rupen, Lisa M. Young, Caroline E. Simpson, Megan Johnson, Kimberly A. Herrmann, Dana Ficut-Vicas, Phil Cigan, Volker Heesen, Trisha Ashley, Hong-Xin Zhang

We decompose the rotation curves in terms of the dynamical contributions by baryons and dark matter halos, and compare the latter with those of dwarf galaxies from THINGS as well as Lambda CDM SPH simulations in which the effect of baryonic feedback processes is included.
