Mapping the Stellar Dynamics of M31
Helen Merrett, M. Merrifield, K. Kuijken +12
Using the Planetary Nebula Spectrograph, we have observed and measured the velocities for some 2764 PNe in the disk and halo of the Andromeda galaxy. Preliminary analysis using a b…
Star Clusters in M31: Old Clusters with Bar Kinematics
H. Morrison, N. Caldwell, R. Schiavon +3
We analyze our accurate kinematical data for the old clusters in the inner regions of M31. These velocities are based on high S/N Hectospec data (Caldwell et al 2010). The data are…
FOBOS: A Next-Generation Spectroscopic Facility at the W. M. Keck Observatory
K. Bundy, K. Westfall, N. MacDonald +38
High-multiplex and deep spectroscopic follow-up of upcoming panoramic deep-imaging surveys like LSST, Euclid, and WFIRST is a widely recognized and increasingly urgent necessity. N…
The paucity of globular clusters around the field elliptical NGC 7507
J. P. Caso, T. Richtler, L. P. Bassino +3
Context: There is strong evidence that globular cluster systems (GCSs) of massive galaxies are largely assembled by infall/accretion processes. Therefore, we expect the GCSs of iso…
The Araucaria Project. An Accurate Distance to the Local Group Galaxy NGC 6822 from Near-Infrared Photometry of Cepheid Variables
W. Gieren, G. Pietrzynski, K. Nalewajko +5
We have measured near-infrared magnitudes in the J and K bands for 56 Cepheid variables in the Local Group galaxy NGC 6822 with well-determined periods and optical light curves in…
