The MASSIVE Survey II: Stellar Population Trends Out to Large Radius in Massive Early Type Galaxies
Jenny E. Greene, Ryan Janish, Chung-Pei Ma +4
We examine stellar population gradients in ~100 massive early type galaxies spanning 180 < sigma* < 370 km/s and M_K of -22.5 to -26.5 mag, observed as part of the MASSIVE survey (…
The MASSIVE Survey - I. A Volume-Limited Integral-Field Spectroscopic Study of the Most Massive Early-Type Galaxies within 108 Mpc
Chung-Pei Ma, Jenny E. Greene, Nicholas McConnell +4
Massive early-type galaxies represent the modern-day remnants of the earliest major star formation episodes in the history of the universe. These galaxies are central to our unders…
Dwarf Galaxy Dark Matter Density Profiles Inferred from Stellar and Gas Kinematics
Joshua J. Adams, Joshua D. Simon, Maximilian H. Fabricius +9
We present new constraints on the density profiles of dark matter (DM) halos in seven nearby dwarf galaxies from measurements of their integrated stellar light and gas kinematics.…
The Stellar Haloes of Massive Elliptical Galaxies III: Kinematics at Large Radius
Sudhir Raskutti, Jenny Greene, Jeremy Murphy
We present a 2D kinematic analysis out to ~2-5 effective radii (Re) of 33 massive elliptical galaxies with stellar velocity dispersions larger than 150 km/s. Our observations were…
The Rising Stellar Velocity Dispersion of M87 from Integrated Starlight
Jeremy D. Murphy, Karl Gebhardt, Mason Cradit
We have measured the line-of-sight velocity distribution from integrated stellar light at two points in the outer halo of M87 (NGC 4486), the second-rank galaxy in the Virgo Cluste…
