Telescope Imaging Spectrograph Parallel Observations of the Planetary Nebula M 94 - 20 1
The planetary nebula M94–20 in the Large Magellanic Cloud was serendipitously observed with the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope as part of the Hubble Space Telescope Archival Pure Parallel Program. We present spatially resolved imaging and spectral data of the nebula and compare them with ground based data, including detection of several emission lines f...
متن کاملA deep kinematic survey of planetary nebulae in the Andromeda Galaxy using the Planetary Nebula Spectrograph
We present a catalogue of positions, magnitudes and velocities for 3300 emission-line objects found by the Planetary Nebula Spectrograph in a survey of the Andromeda Galaxy, M31. Of these objects, 2615 are found likely to be planetary nebulae (PNe) associated with M31. The survey area covers the whole of M31’s disk out to a radius of 1.5. Beyond this radius, observations have been made along th...
متن کاملSpitzer Infrared Spectrograph (irs) Observations of Large Magellanic Cloud Planetary Nebula Smp 83
The first observations of the infrared spectrum of the LMC planetary nebula SMP 83 as observed by the recently launched Spitzer Space Telescope are presented. The high-resolution (R 600) spectrum shows strong emission lines but no significant continuum. The infrared fine-structure lines are used, together with published optical spectra, to derive the electron temperature of the ionized gas for ...

متن کاملThe Spectrograph
JILA Fellow John Hall will deliver the 2006 Richard C. Lord Lecture on May 2, on “Optical clocks, combs and coherence: defining and measuring optical frequency.” Born in 1934 in Denver, Hall is an alumnus of the Carnegie Institute of Technology, where he received B.S., M.S. and Ph.D. degrees. He conducted postdoctoral studies at the Department of Commerce’s National Bureau of Standards, now cal...
