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…
On origin and destruction of relativistic dust and its implication for ultrahigh energy cosmic rays
Thiem Hoang, A. Lazarian, R. Schlickeiser
Dust grains may be accelerated to relativistic speeds by radiation pressure, diffusive shocks, and other acceleration mechanisms. Such relativistic grains have been suggested as pr…
Modeling Grain Alignment by Radiative Torques and Hydrogen Formation Torques in Reflection Nebula
Thiem Hoang, A Lazarian, B-G Andersson
Reflection nebulae--dense cores--illuminated by surrounding stars offer a unique opportunity to directly test our quantitative model of grain alignment based on radiative torques (…
Evidence for (and Against) Progenitor Bias in the Size Growth of Compact Red Galaxies
Stephanie K. Keating, Roberto G. Abraham, Ricardo P. Schiavon +5
Most massive passive galaxies are compact at high redshifts, but similarly compact massive galaxies are rare in the local universe. The most common interpretation of this phenomeno…
The Q/U Imaging Experiment: Polarization Measurements of Radio Sources at 43 and 95 GHz
QUIET Collaboration, K. M. Huffenberger, D. Araujo +24
We present polarization measurements of extragalactic radio sources observed during the Cosmic Microwave Background polarization survey of the Q/U Imaging Experiment (QUIET), opera…
The JCMT Legacy Survey of the Gould Belt: a molecular line study of the Ophiuchus molecular cloud
Glenn J. White, Emily Drabek-Maunder, Erik Rosolowsky +17
CO, CO and CO = 3--2 observations are presented of the Ophiuchus molecular cloud. The CO and CO emission is dominated by the Oph A clump, and…
