Dynamical Properties of Collisionless Star Streams
Raymond G. Carlberg
A sufficiently extended satellite in the tidal field of a host galaxy loses mass to create nearly symmetric leading and trailing tidal streams. We study the case in which tidal hea…
The JCMT Gould Belt Survey: Evidence for radiative heating in Serpens MWC 297 and its influence on local star formation
D. Rumble, J. Hatchell, R. A. Gutermuth +61
We present SCUBA-2 450micron and 850micron observations of the Serpens MWC 297 region, part of the JCMT Gould Belt Survey of nearby star-forming regions. Simulations suggest that r…
Deconstructing Thermal Sunyaev-Zel'dovich - Gravitational Lensing Cross-Correlations: Implications for the Intracluster Medium
N. Battaglia, J. C. Hill, N. Murray
Recent first detections of the cross-correlation of the thermal Sunyaev-Zel'dovich (tSZ) signal in Planck cosmic microwave background (CMB) temperature maps with gravitational lens…
Sub-stellar Companions and Stellar Multiplicity in the Taurus Star-Forming Region
Sebastian Daemgen, Mariangela Bonavita, Ray Jayawardhana +2
We present results from a large, high-spatial-resolution near-infrared imaging search for stellar and sub-stellar companions in the Taurus-Auriga star-forming region. The sample co…
The MaNGA Integral Field Unit Fiber Feed System for the Sloan 2.5 m Telescope
N. Drory, N. MacDonald, M. A. Bershady +22
We describe the design, manufacture, and performance of bare-fiber integral field units (IFUs) for the SDSS-IV survey MaNGA (Mapping Nearby Galaxies at APO) on the the Sloan 2.5 m…
Overview of the SDSS-IV MaNGA Survey: Mapping Nearby Galaxies at Apache Point Observatory
Kevin Bundy, Matthew A. Bershady, David R. Law +65
We present an overview of a new integral field spectroscopic survey called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory), one of three core programs in the fourth-gen…
