• Ionized Gas Kinematics At High Resolution. IV. Star Formation And A Rotating Core In The Medusa (NGC 4194) 

      Beck, Sara C.; Lacy, John; Turner, Jean; Greathouse, Thomas K.; Neff, Susan (2014-05)
      NGC 4194 is a post-merger starburst known as The Medusa for its striking tidal features. We present here a detailed study of the structure and kinematics of ionized gas in the central 0.65 kpc of the Medusa. The data include ...
    • Near-Infrared Line Identification In Type Ia Supernovae During The Transitional Phase 

      Friesen, Brian; Baron, E.; Wisniewski, John P.; Parrent, Jerod T.; Thomas, R. C.; Miller, Timothy R.; Marion, G. H. (2014-09)
      We present near-infrared synthetic spectra of a delayed-detonation hydrodynamical model and compare them to observed spectra of four normal Type Ia supernovae ranging from day +56.5 to day +85. This is the epoch during ...
    • Observations Of Type Ia Supernova 2014J With Flitecam On SOFIA 

      Vacca, W. D.; Hamilton, R. T.; Savage, M.; Shenoy, S.; Becklin, E. E.; McLean, I. S.; Logsdon, S. E.; Marion, G. H.; Ashok, N. M.; Banerjee, D. P. K.; Evans, A.; Fox, O. D.; Garnavich, Peter; Gehrz, R. D.; Greenhouse, M.; Helton, L. A.; Kirshner, Robert P.; Shenoy, D.; Smith, N.; Spyromilio, J.; Starrfield, S.; Wooden, D. H.; Woodward, C. E. (2015-05)
      We present medium-resolution near-infrared (NIR) spectra, covering 1.1-3.4 mu m, of the normal Type Ia supernova (SN Ia) SN 2014J in M82 obtained with the FLITECAM instrument on board Stratospheric Observatory for Infrared ...
