The JCMT Nearby Galaxies Legacy Survey VI: The distribution of gas and star formation in M81
J. R. Sánchez-Gallego, J. H. Knapen, J. S. Heiner +12
We present a first complete 12 CO J=3-2 map of M81, observed as part of the Nearby Galaxies Legacy Survey being carried out at the James Clerk Maxwell Telescope. We detect 9 region…
A Pilot Study for the SCUBA-2 'All-Sky' Survey
Todd Mackenzie, Filiberto G. Braglia, Andy G. Gibb +30
We have carried out a pilot study for the SCUBA-2 'All-Sky' Survey, SASSy, a wide and shallow mapping project at 850 microns, designed to find rare objects, both Galactic and extra…
Tracing kinematical and physical asymmetries in the jet from DG Tau B
Linda Podio, Jochen Eisloeffel, Stanislav Melnikov +2
Stellar jets can be highly asymmetric and have multiple velocity components. To clarify the origin of jet asymmetries and constrain their launch mechanism we study the physical and…
UWISH2 -- The UKIRT Widefield Infrared Survey for H2
D., Froebrich, C. J. +56
We present the goals and preliminary results of an unbiased, near-infrared, narrow-band imaging survey of the First Galactic Quadrant (10deg<l<65deg ; -1.3deg<b<+1.3deg). This area…
Searching for Jet Rotation in Class 0/I Sources observed with GEMINI/GNIRS
Deirdre Coffey, Francesca Bacciotti, Antonio Chrysostomou +2
In recent years, there has been a number of detections of gradients in the radial velocity profile across jets from young stars. The significance of these results is considerable.…
Whole Earth Telescope Observations of the subdwarf B star KPD 1930+2752: A rich, short period pulsator in a close binary
M. D. Reed, S. L. Harms, S. Poindexter +58
KPD 1930+2752 is a short-period pulsating subdwarf B (sdB) star. It is also an ellipsoidal variable with a known binary period just over two hours. The companion is most likely a w…
The Bolocam Galactic Plane Survey IV: 1.1 and 0.35 mm Dust Continuum Emission in the Galactic Center Region
John Bally, James Aguirre, Cara Battersby +17
The Bolocam Galactic Plane Survey (BGPS) data for a six square degree region of the Galactic plane containing the Galactic center is analyzed and compared to infrared and radio con…
The Bolocam Galactic Plane Survey: Survey Description and Data Reduction
James E. Aguirre, Adam G. Ginsburg, Miranda K. Dunham +13
We present the Bolocam Galactic Plane Survey (BGPS), a 1.1 mm continuum survey at 33" effective resolution of 170 square degrees of the Galactic Plane visible from the northern hem…
Near-Infrared Multi-Band Photometry of the Substellar Companion GJ 758 B
M. Janson, J. Carson, C. Thalmann +46
GJ 758 B is a cold (~600K) companion to a Sun-like star at 29 AU projected separation, which was recently detected with high-contrast imaging. Here we present photometry of the com…
Identification of the Lithium Depletion Boundary and Age of the Southern Open Cluster Blanco 1
P. A. Cargile, D. J. James, R. D. Jeffries
We present results from a spectroscopic study of the very low mass members of the Southern open cluster Blanco 1 using the Gemini-N telescope. We obtained intermediate resolution (…
A Chandra Observation of the Obscured Star-Forming Complex W40
Michael A. Kuhn, Konstantin V. Getman, Eric D. Feigelson +3
The young stellar cluster illuminating the W40 H II region, one of the nearest massive star forming regions, has been observed with the ACIS detector on board the Chandra X-ray Obs…
The Star Formation History of Isolated Dwarf UGC4879
Bradley A. Jacobs, R. Brent Tully, Luca Rizzi +3
Recent observations of UGC4879 with the Advanced Camera for Surveys on the Hubble Space Telescope confirm that it is a nearby isolated dwarf irregular galaxy. We measure a distance…
The JCMT Nearby Galaxies Legacy Survey IV. Velocity Dispersions in the Molecular Interstellar Medium in Spiral Galaxies
C. D. Wilson, B. E. Warren, J. Irwin +21
An analysis of large-area CO J=3-2 maps from the James Clerk Maxwell Telescope for 12 nearby spiral galaxies reveals low velocity dispersions in the molecular component of the inte…
Classifying -algebras with both finite and infinite subquotients
Soren Eilers, Gunnar Restorff, Efren Ruiz
We give a classification result for a certain class of -algebras over a finite topological space in which there exists an open set of such that $U…
The JCMT Nearby Galaxies Legacy Survey V: The CO(J=3-2) Distribution and Molecular Outflow in NGC~4631
Judith A. Irwin, C. D. Wilson, T. Wiegert +10
We have made the first map of CO(J=3-2) emission covering the disk of the edge-on galaxy, NGC~4631, which is known for its spectacular gaseous halo. The strongest emission, which w…
Metallicity Gradients and Gas Flows in Galaxy Pairs
Lisa J. Kewley, David Rupke, H. Jabran Zahid +2
We present the first systematic investigation into the metallicity gradients in galaxy close pairs. We determine the metallicity gradients for 8 galaxies in close pairs using HII r…
A Large Number of z > 6 Galaxies around a QSO at z = 6.43: Evidence for a Protocluster?
Yousuke Utsumi, Tomotsugu Goto, Nobunari Kashikawa +4
QSOs have been thought to be important for tracing highly biased regions in the early universe, from which the present-day massive galaxies and galaxy clusters formed. While overde…
