The James Clerk Maxwell Telescope Nearby Galaxies Legacy Survey IX: CO Observations of NGC 2976 and NGC 3351
Boon-Kok Tan, J. Leech, D. Rigopoulou +20
We present CO \textit{J=32} maps of NGC 2976 and NGC 3351 obtained with the James Clerk Maxwell Telescope (JCMT), both early targets of the JCMT Nearby Galaxy L…
Star Formation in Two Luminous Spiral Galaxies
Deidre A. Hunter, Bruce G. Elmegreen, Vera C. Rubin +4
We have examined star formation in two very luminous (M_V=-22 to -23) Sc-type spiral galaxies, NGC 801 and UGC 2885, using ultra-deep Halpha images. We combine these with UBV and 2…
Fine-scale structure of the quasar 3C 279 Measured with 1.3 mm very long baseline interferometry
Ru-Sen Lu, Vincent L. Fish, Kazunori Akiyama +30
We report results from 5-day VLBI observations of the well-known quasar 3C 279 at 1.3 mm (230 GHz) in 2011. The measured nonzero closure phases on triangles including stations in A…
A CO J=3-2 map of M51 with HARP-B: Radial properties of the spiral structure
C. Vlahakis, P. van der Werf, F. P. Israel +1
We present the first complete CO J=3-2 map of the nearby grand-design spiral galaxy M51 (NGC 5194), at a spatial resolution of ~600 pc, obtained with the HARP-B instrument on the J…
Doubly-periodic instability pattern in a smectic A liquid crystal
O. V. Manyuhina, G. Tordini, W. Bras +2
We report the observation of a doubly-periodic surface defect-pattern in the liquid crystal 8CB, formed during the nematic--smectic A phase transition. The pattern results from the…
SCUBA-2: iterative map-making with the Sub-Millimetre User Reduction Facility
Edward L. Chapin, David S. Berry, Andrew G. Gibb +5
The Submillimetre Common User Bolometer Array 2 (SCUBA-2) is an instrument operating on the 15-m James Clerk Maxwell Telescope, nominally consisting of 5120 bolometers in each of t…
