      Directly detecting thermal emission from young extrasolar planets allows measurement of their atmospheric composition and luminosity, which is influenced by their formation mechanism. Using the Gemini Planet Imager, we ...

    • Grand-design spirals in the core of NGC 5248 

      Laine, S.; Knapen, J.; Perez-Ramirez, D.; Doyon, R.; Nadeau, D. (2001)
      We report the detection of a bisymmetric nuclear spiral structure in the spiral galaxy NGC 5248.The two red spiral arms can be followed for about 3 arcsec, before they appear to end inside the radius of the circumnuclear ...

    • M100 and NGC 6951: Morphological Clues to Central Dynamics 

      Knapen, J.; Shlosman, I.; Beckman, J.E.; Heller, C.H.; Peletier, R.F.; de Jong, R.S.; Nadeau, D.; Doyon, R. (Astronomical Society of the Pacific, 1996)
      High-resolution optical and NIR observations are used to constrain a dynamical model of the circumnuclear star forming (SF) region in the barred galaxy M100 (NGC 4321). Small leading arms observed in our K-band image of ...

    • A nuclear grand-design spiral within the normal disc spiral of NGC 5248 

      Laine, S.; Knapen, J.; Perez-Ramirez, D.; Doyon, R.; Nadeau, D. (1999-01)
      We report the discovery of trailing grand-design nuclear spiral structure in the spiral galaxy NGC 5248. Two tightly-wound red spiral arms, with widths less than 1 arcsec (~ 75 pc), emanate at 1 arcsec outside the quiescent ...

    • A Subarcsecond Resolution Near infrared Study of Seyfert and “Normal” Galaxies. I. Imaging Data 

      Peletier, R.F.; Knapen, J.; Shlosman, I.; Perez-Ramirez, D.; Nadeau, D.; Doyon, R.; Rodriguez Espinosa, J.M.; Garcia Perez, A.M. (1999-12)
      We present new high-resolution near-infrared observations in the J, H, and K bands, obtained to study the properties of Seyfert host galaxies. The data set consists of images in the three bands of practically the entire ...
