We present rotation curve fits to 175 late-type galaxies from the Spitzer Photometry & Accurate Rotation Curves (SPARC) database using seven dark matter (DM) halo profiles: pseudo-isothermal (pISO), Burkert, Navarro-Frenk-White (NFW), Einasto, Di Cintio (2014, DC14), coreNFW, and a new semi-empirical profile named Lucky13. We marginalize over stellar mass-to-light ratio, galaxy distance, disk inclination, halo concentration and halo mass (and an additional shape parameter for Einasto) using a Markov Chain Monte Carlo method. We find that cored halo models such as the DC14 and Burkert profiles generally provide better fits to rotation curves than the cuspy NFW profile. The stellar mass-halo mass relation from abundance matching is recovered by all halo profiles once imposed as a Bayesian prior, whereas the halo mass-concentration relation is not reproduced in detail by any halo model. We provide an extensive set of figures as well as best-fit parameters in machine-readable tables to facilitate model comparison and the exploration of DM halo properties.

Darkness Visible: N-Body Simulations of Dark Matter Spikes in Hernquist Haloes
N-body simulations of adiabatic black hole growth in Hernquist haloes yield an empirical spike profile with outer halo depletion and a mass-ratio-dependent spike radius that deviates from analytical predictions.

Vertical Structure and Dynamics of a Galactic Disk
A review of a multi-component disk plus halo model, arguing that gas and dark matter vertically confine the stellar disk, producing steeper-than-sech^2 profiles and flaring.
