The VIRUS-P Exploration of Nearby Galaxies (VENGA): The Xco Gradient in NGC 628
Guillermo A. Blanc, Andreas Schruba, Neal J. Evans +13
We measure the radial profile of the 12CO(1-0) to H_2 conversion factor (Xco) in NGC 628. The Hαemission from the VENGA integral field spectroscopy is used to map the star formatio…
A Stellar Dynamical Mass Measurement of the Black Hole in NGC 3998 from Keck Adaptive Optics Observations
Jonelle L. Walsh, Remco C. E. van den Bosch, Aaron J. Barth +1
We present a new stellar dynamical mass measurement of the black hole in the nearby, S0 galaxy NGC 3998. By combining laser guide star adaptive optics observations obtained with th…
Orbit-based dynamical models of the Sculptor dSph galaxy
Maarten A. Breddels, A. Helmi, R. C. E. van den Bosch +2
We have developed spherically symmetric dynamical models of dwarf spheroidal galaxies using Schwarzschild's orbit superposition method. This type of modelling yields constraints bo…
The SAURON project-XXI. The spatially-resolved UV-line strength relations of early-type galaxies
Hyunjin Jeong, Sukyoung K. Yi, Martin Bureau +13
The unexpected rising flux of early-type galaxies at decreasing ultraviolet (UV) wavelengths is a long-standing mystery. One important observational constraint is the correlation b…
