Age dating a starburst: Gemini/CIRPASS observations of the core of M 83
Ryder, S.D.; Knapen, J.; Mazzuca, L.M.; Sharp, R.G.; Parry, I.R. (Astronomical Society of the Pacific, 2004)The circumnuclear starburst in NGC 5236 (M 83) has been studied photometrically by Harris et al. (2001) using HST/WFPC2 images in the broad-band near-UV and optical, as well as narrow-band H® and H¯ to derive colors and ... -
Age-dating a star-burst with GEMINI/CIRPASS observations of the core of M83
Sharp, R.G.; Parry, I.R.; Ryder, S.D.; Knapen, J.; Mazzuca, L.M. (2004)We present preliminary results from a set of near-IR integral field spectroscopic observations of the central, star-burst, regions of the barred spiral galaxy M83, obtained with CIRPASS on Gemini-S. We present maps in the ... -
The Circumnuclear Starburst in M83
Ryder, S.D.; Sharp, R.G.; Knapen, J.; Mazzuca, L.M.; Parry, I.R. (American Institute of Physics (AIP), 2005)We present results from near-infrared integral-field spectroscopy of the circumnuclear starburst in M83, using the CIRPASS instrument on Gemini South. The combination of Pa, CO (6,3), and [Fe II] equivalent width measurements ... -
The distribution of star formation in the central regions of spiral galaxies
Mazzuca, L.M.; Knapen, J.; Regan, M.; Veilleux, S. (American Institute of Physics (AIP), 2005)Nuclear rings are characterized by their high star formation rates, and are believed to be the products of gas inflow towards the inner regions of spiral galaxies. We present first results from a statistical survey of these ... -
High-resolution imaging of stars, dust, and star formation in nuclear rings in galaxies
Mazzuca, L.M.; Knapen, J.; Regan, M.; Boker, T. (Astronomical Society of the Pacific, 2001)Nuclear rings in barred spiral galaxies offer an opportunity to study starburst properties, as well as the evolution of star formation in the central regions of galaxies. To further our understanding in these areas, a large ... -
