    • The Effect of Projection on Derived Mass-Size and Linewidth-Size Relationships 

      Shetty, Rahul; Collins, David C.; Kauffmann, Jens; Goodman, Alyssa; Rosolowsky, Erik W.; Norman, Michael L. (American Astronomical Society, 2010)
      Power-law mass-size and linewidth-size correlations, two of "Larson's laws," are often studied to assess the dynamical state of clumps within molecular clouds. Using the result of a hydrodynamic simulation of a molecular ...

    • Extreme Brightness Temperatures and Refractive Substructure in 3C 273 with RadioAstron 

      Johnson, Michael D.; Kovalev, Yuri Y.; Gwinn, Carl R.; Gurvits, Leonid I.; Narayan, Ramesh; Macquart, Jean-Pierre; Jauncey, David L.; Voitsik, Peter A.; Anderson, James M.; Sokolovsky, Kirill V.; Lisakov, Mikhail M. (American Astronomical Society, 2016)
      Earth–space interferometry with RadioAstron provides the highest direct angular resolution ever achieved in astronomy at any wavelength. RadioAstron detections of the classic quasar 3C 273 on interferometric baselines up ...

    • A Full-Sky, High-Resolution Atlas of Galactic 12 μM Dust Emission With WISE 

      Meisner, Aaron; Finkbeiner, Douglas (IOP Publishing, 2013)
      We describe our custom processing of the entire Wide-field Infrared Survey Explorer (WISE) 12 μm imaging data set, and present a high-resolution, full-sky map of diffuse Galactic dust emission that is free of compact sources ...

    • Low frequency observations of linearly polarized structures in the interstellar medium near the south Galactic pole 

      Lenc, E.; Gaensler, B; Sun, X. H.; Sadler, E. M.; Willis, A. G.; Barry, N.; Beardsley, A. P.; Bell, M. E.; Bernardi, G.; Bowman, J. D.; Briggs, F.; Callingham, J. R.; Cappallo, R. J.; Carroll, P.; Corey, B. E.; Oliveira-Costa, A. de; Deshpande, A. A.; Dillon, J. S.; Dwarkanath, K. S.; Emrich, D.; Ewall-Wice, A.; Feng, L.; For, B.-Q.; Goeke, R.; Greenhill, Lincoln Jared; Hancock, P.; Hazelton, B. J.; Hewitt, J. N.; Hindson, L.; Hurley-Walker, N.; Johnston-Hollitt, M.; Jacobs, D. C.; Kapińska, A. D.; Kaplan, D. L.; Kasper, Justin C.; Kim, H.-S.; Kratzenberg, E.; Line, J.; Loeb, Abraham; Lonsdale, C. J.; Lynch, M. J.; McKinley, B.; McWhirter, S. R.; Mitchell, D. A.; Morales, M. F.; Morgan, E.; Morgan, J.; Murphy, T.; Neben, A. R.; Oberoi, D.; Offringa, A. R.; Ord, S; Paul, S.; Pindor, B.; Pober, J. C.; Prabu, T.; Procopio, P.; Riding, J.; Rogers, A. E. E.; Roshi, A. (American Astronomical Society, 2016)
      We present deep polarimetric observations at 154 MHz with the Murchison Widefield Array (MWA), covering 625 deg^2 centered on RA=0 h, Dec=-27 deg. The sensitivity available in our deep observations allows an in-band, ...

    • Measuring Distances and Reddenings for a Billion Stars: Toward a 3d Dust Map From Pan-Starrs 1 

      Green, Gregory Maurice; Schlafly, Edward F.; Finkbeiner, Douglas; Jurić, Mario; Rix, Hans-Walter; Burgett, Will; Chambers, Kenneth C.; Draper, Peter W.; Flewelling, Heather; Kudritzki, Rolf Peter; Magnier, Eugene; Martin, Nicolas; Metcalfe, Nigel; Tonry, John; Wainscoat, Richard; Waters, Christopher (IOP Publishing, 2014)
      We present a method to infer reddenings and distances to stars based only on their broad-band photometry, and show how this method can be used to produce a three-dimensional (3D) dust map of the Galaxy. Our method samples ...

    • The QUaD Galactic Plane Survey 1: Maps And Analysis of Diffuse Emission 

      Culverhouse, T.; Ade, P.; Bock, J.; Bowden, M.; Brown, M.; Cahill, G.; Castro, P.; Church, S.; Friedman, R.; Ganga, K.; Gear, W.; Gupta, S.; Hinderks, J.; Kovac, John M; Lange, A.; Leitch, E.; Melhuish, S.; Memari, Y.; Murphy, J.; Orlando, A.; Schwarz, R.; O'Sullivan, C.; Piccirillo, L.; Pryke, C; Rajguru, N.; Rusholme, B.; Taylor, A.; Thompson, K.; Turner, A.; Wu, E.; Zemcov, M. (IOP Publishing, 2010)
      We present a survey of ∼ 800 square degrees of the galactic plane observed with the QUaD telescope. The primary product of the survey are maps of Stokes I, Q and U parameters at 100 and 150 GHz, with spatial resolution 5 ...
