A DECam View of the Diffuse Dwarf Galaxy Crater II: Variable Stars
A. Katherina Vivas, Alistair R. Walker, Clara E. Martínez-Vázquez +11
Time series observations of a single dithered field centered on the diffuse dwarf satellite galaxy Crater II were obtained with the Dark Energy Camera (DECam) at the 4m Blanco Tele…
Metallicity Structure in the Milky Way Disk Revealed by Galactic HII Regions
Trey V. Wenger, Dana S. Balser, L. D. Anderson +1
The metallicity structure of the Milky Way disk stems from the chemodynamical evolutionary history of the Galaxy. We use the National Radio Astronomy Observatory Karl G. Jansky Ver…
Changes: The Past, Present, and Future of the Nearby Dwarf Galaxy NGC 55
T. J. Davidge
Spectra that cover wavelengths from 0.6 to 1.1um are used to examine the behavior of emission and absorption features in a contiguous 22 x 300 arcsec region centered on the nearby…
Through thick or thin: Multiple components of the magneto-ionic medium towards the nearby region Sharpless 2-27 revealed by Faraday tomography
Alec J. M. Thomson, T. L. Landecker, John M. Dickey +12
Sharpless 2-27 (Sh2-27) is a nearby region excited by Oph. We present observations of polarized radio emission from 300 to 480MHz towards Sh2-27, made…
The MASSIVE survey - XI. What drives the molecular gas properties of early-type galaxies
Timothy A. Davis, Jenny E. Greene, Chung-Pei Ma +5
In this paper we study the molecular gas content of a representative sample of 67 of the most massive early-type galaxies in the local universe, drawn uniformly from the MASSIVE su…
A 5deg x 5deg deep HI survey of the M81 group
A. Sorgho, T. Foster, C. Carignan +1
A 25 region, including the M81 complex (M81, M82, NGC 3077), NGC 2976 and IC2574, was mapped during ~3000 hours with the DRAO synthesis telescope. With a physical resol…
