  • Circular polarization in PKS 1519-273 

    Bennett, Wendy (2007-05-31)
    The intra-day variable BL Lac PKS 1519-273 exhibits variations at centimeter wavelengths in total intensity, linear polarization, and circular polarization. The variability is caused by scintillation due to the interstellar ...
  • Hubble space telescope imaging of seyfert galaxies 

    Bennett, Wendy; Madland, Mark; Weinzirl, Timothy; Nelson, Charles H. (2007-06-01)
    Recent searches for massive black holes in galactic nuclei show that they are common if not ubiquitous. Furthermore, there are important relationships between black hole mass and properties characterizing the size and ...
  • "Spectroscopy of star-forming regions in UV bright, interacting starburst galaxies" 

    Frazier, Aaron G.; Nelson, Charles H. (2005-06-23)
    We have obtained long-slit spectroscopy of the star-forming regions in NGC3395, NGC3396, NGC3991, NGC3994, and NGC3995 emit strongly in the ultraviolet, indicating multiple regions of active star formation. To investigate ...
  • Star formation in UV-bright interacting galaxies 

    Hulsebus, Alan; Nelson, Charles H.; Ragan, Sarah; McGleam, Catherine (2007-05-31)
    Galaxy interactions are known to drive interstellar gas toward the nuclear regions, thus triggering bursts of star formation. To investigate the relationship between galaxy interactions and the induced star formation, we ...
  • "Star formation in UV-bright interacting galaxies" 

    Hulsebus, Alan; Nelson, Charles H.; Ragan, Sarah; McGleam, Catherine (2005-06-23)
    The interacting pair NGC3395 and NGC3396 and the interacting trio and NGC3991, NGC3994, and NGC3995 emit strongly in the ultraviolet, indicating multiple regions of active star formation. To investigate the nature of the ...
