Constraining the Magnetic Field of the Smith High Velocity Cloud using Faraday rotation
S. K. Betti, Alex S. Hill, S. A. Mao +4
The Smith Cloud is a high velocity cloud (HVC) with an orbit suggesting it has made at least one passage through the Milky Way disk. A magnetic field found around this cloud has be…
The Galactic Magneto-Ionic Medium Survey: Moments of the Faraday Spectra
John M. Dickey, T. L. Landecker, A. J. M. Thomson +11
Faraday rotation occurs along every line of sight in the Galaxy; Rotation Measure (RM) synthesis allows a three-dimensional representation of the interstellar magnetic field. This…
Is there a polarization horizon?
A. S. Hill
Modern radio spectrometers make measurement of polarized intensity as a function of Faraday depth possible. I investigate the effect of depolarization along a model line of sight.…
The Stellar Contents of Intermediate Mass Disk Galaxies in the Virgo Cluster. I. GMOS Spectra
T. J. Davidge
The stellar contents of six intermediate mass early-type disk galaxies in the Virgo cluster are examined using deep long slit spectra. The isophotal and photometric properties of t…
The large-scale structure of the halo of the Andromeda galaxy II. Hierarchical structure in the Pan-Andromeda Archaeological Survey
Alan W. McConnachie, Rodrigo Ibata, Nicolas Martin +29
The Pan-Andromeda Archaeological Survey is a survey of square degrees centered on the Andromeda (M31) and Triangulum (M33) galaxies that has provided the most extensive pano…
Variable Stars in Local Group Galaxies. IV. RR Lyrae stars in the central regions of the low-density galaxy Crater II
M. Monelli, A. R. Walker, C. E. Martìnez-Vàzquez +9
We present a search and analysis of variable stars in the recently discovered Crater~II dwarf galaxy. Based on , , data collected with the Isaac Newton Telescope (FoV$\si…
