Cuspy No More: How Outflows Affect the Central Dark Matter and Baryon Distribution in Lambda CDM Galaxies
Fabio Governato,Adi Zolotov,Andrew Pontzen,Charlotte Christensen,Se-Heon Oh,Alyson Brooks,Thomas R. Quinn,Sijing Shen,James Wadsley +8 more
TL;DR: In this paper, the authors examined the evolution of the inner dark matter (DM) and baryonic density profile of simulated field galaxies using fully cosmological, Lambda CDM, high resolution SPH + N-Body simulations.
Journal ArticleDOI
High-Resolution Dark Matter Density Profiles of THINGS Dwarf Galaxies: Correcting for Noncircular Motions
TL;DR: In this paper, a new method was proposed to remove the impact of random and small-scale noncircular motions from H I velocity fields in (dwarf) galaxies in order to better constrain the dark matter properties for these objects.
Journal ArticleDOI
High-resolution dark matter density profiles of THINGS dwarf galaxies: Correcting for non-circular motions
TL;DR: In this article, a method to remove the impact of random and small-scale non-circular motions from HI velocity fields in galaxies in order to better constrain the dark matter properties for these objects is presented.
Journal ArticleDOI
The central slope of dark matter cores in dwarf galaxies: Simulations vs. THINGS
Se-Heon Oh,Chris B. Brook,Fabio Governato,Elias Brinks,Lucio Mayer,W. J. G. de Blok,Alyson Brooks,Fabian Walter +7 more
TL;DR: In this paper, a direct comparison of the derived dark matter distributions between hydrodynamical simulations of dwarf galaxies assuming a LCDM cosmology and the observed dwarf galaxies sample from the THINGS survey in terms of rotation curve shape and the logarithmic inner density slope alpha of mass density profiles is made.
Journal ArticleDOI

Bärbel S. Koribalski,Jing Wang,Jing Wang,P. Kamphuis,P. Kamphuis,Tobias Westmeier,Lister Staveley-Smith,Se-Heon Oh,Se-Heon Oh,Angel R. Lopez-Sanchez,O. I. Wong,Juergen Ott,W. J. G. de Blok,Li Shao +13 more
TL;DR: The Local Volume HI Survey (LVHIS) as discussed by the authors consists of all galaxies with Local Group velocities v_LG < 550 km/s or distances D < 10 Mpc that are detected in the HI Parkes All Sky Survey (HIPASS).
