M.; Sergeev, S. G.; Tao, J.; Tokarz, S.; Wagner, R. M.; Wamsteker, W.; Wilkes, Belinda Jane (EDP Sciences, 2001)
      Mid-infrared images of the Seyfert 1 galaxy Mrk 279 obtained with the ISO satellite are presented together with the results of a one-year monitoring campaign of the 2.5-11.7 micron spectrum. Contemporaneous optical photometric ...

    • Optical Spectroscopy of Type Ia Supernovae 

      Matheson, T.; Kirshner, Robert P.; Challis, Peter M.; Jha, S.; Garnavich, P. M.; Berlind, Perry; Calkins, Michael Lee; Blondin, S.; Balog, Z.; Bragg, A. E.; Caldwell, Nelson; Concannon, K.
