B.; Ferguson, H.; Francis, P. J.; French, L.; Bolte, M.; Roth, J.; Odewahn, S.; Howell, S.; Krzeminski, W. (American Astronomical Society, 1996-12)
      BV(RI)_KC_ light curves are presented for 27 type Ia supernovae discovered during the course of the Calan/Tololo Survey and for two other SNe Ia observed during the same period. Estimates of the maximum light magnitudes ...
    • THE EXPANDING PHOTOSPHERE METHOD APPLIED TO SN-1992AM AT CZ=14600KM-S 
      Schmidt, Brian P.; Kirshner, Robert P.; Eastman, Ronald G.; Hamuy Wackenhut, Mario; Phillips, Mark M.; Suntzeff, Nicholas B.; Maza Sancho, José; Filippenko, Alexei V.; Ho, Luis C.; Matheson, Thomas; Grashuis, Randy; Aviles, Roberto; Kirkpatrick, J. Davy; Challis, Peter; Kuijken, Konrad; Zucker, Daniel; Bolte, Michael; Tyson, Neil D. (AMER INST PHYSICS, 1994-04)
      We present photometry and spectroscopy of SN 1992am for five months following its discovery by the Calan/CTIO SN search. These data show SN 1992am to be type II-P, displaying hydrogen in its spectrum and the typical shoulder ...
    • The stellar spectral features of nearby galaxies in the near infrared: tracers of thermally pulsing asymptotic ... 
      Riffel, Rogerio; Mason, Rachel; Martins, Lucimara; Rodríguez Ardila, Alberto; Ho, Luis C.; Riffel, Rogemar A.; Lira Teillery, Paulina; González Martín, Omaira; Ruschel Dutra, Daniel; Alonso Herrero, Almudena; Helene, Flohic; McDermid, Richard; Ramos Almeida, Cristina; Thanjavur, Karun; Winge, Claudia (2015)
      We analyse the stellar absorption features in high signal-to-noise ratio (S/N) near-infrared (NIR) spectra of the nuclear region of 12 nearby galaxies, mostly spirals. The features detected in some or all of the galaxies ...
    • The HASHTAG Project: the first submillimeter images of the Andromeda Galaxy from the Ground

      Observing nearby galaxies with submillimeter telescopes on the ground has two major challenges. First, the brightness is significantly reduced at long submillimeter wavelengths compared to the brightness at the peak of the ...
