    • ALMA Observations of the Water Fountain Pre-Planetary Nebula IRAS 16342-3814: High-velocity bipolar jets and an Expanding Torus 

      Sahai, Raghvendra; Vlemmings, W.H.T.; Gledhill, Timothy; Sanchez Contreras, Carmen; Lagadec, Eric; Nyman, L.A.; Quintana-Lacaci, G. (2017-01-20)
      We have mapped 12CO J=3–2 and other molecular lines from the “water fountain” bipolar pre-planetary nebula (PPN) IRAS 16342-3814 with ∼0.35″ resolution using Atacama Large Millimeter/submillimeter Array. We find (i) two ...

    • The excitation mechanisms and evolutionary stages of UWISH2 planetary nebula candidates 

      Jones, Alex; Gledhill, Timothy; Froebrich, Dirk; Smith, Michael (2018-10-01)
      We present medium-resolution K-band long-slit spectroscopy of 29 true, likely, possible, and candidate Galactic Plane planetary nebulae (PNe) from the UWISH 2 survey, many of which have only been recently discovered. These ...

    • A First Look at BISTRO Observations of the ρ Oph-A core 

      BISTRO; Gledhill, Timothy (2018-05-16)
      We present 850 μm imaging polarimetry data of the ρ Oph-A core taken with the Submillimeter Common-User Bolometer Array-2 (SCUBA-2) and its polarimeter (POL-2) as part of our ongoing survey project, -fields In STar forming ...

    • Magnetic Fields toward Ophiuchus-B Derived from SCUBA-2 Polarization Measurements 

      BISTRO; Gledhill, Timothy (2018-07-01)
      We present the results of dust emission polarization measurements of Ophiuchus-B (Oph-B) carried out using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) camera with its associated polarimeter (POL-2) on the ...

    • Planetary Nebulae in the UWISH2 Galactic Plane survey 

      Gledhill, Timothy; Froebrich, D. (Cambridge University Press, 2017-09-30)
      UWISH2 is the first unbiassed imaging survey of v$=1-0$~S(1) molecular hydrogen emission ($\lambda=2.122~\mu$m) in the northern Galactic Plane. Here we discuss 284 extended emission line objects which we consider to be ...

    • Planetary Nebulae in the UWISH2 survey 

      Gledhill, Timothy; Froebrich, Dirk; Campbell-White, J.; Jones, Alex (2018-09-21)
      Near-infrared imaging in the 1 - 0 S(1) emission line of molecular hydrogen is able to detect planetary nebulae (PNe) that are hidden from optical emission line surveys.We present images of 307 objects from the UWISH2 ...
