Using Hubble Space Telescope Imaging of Nuclear Dust Morphology to Rule Out Bars Fueling Seyfert Nuclei
Michael W. Regan, John S. Mulchaey
If AGN are powered by the accretion of matter onto massive black holes, how does the gas in the host galaxy lose the required angular momentum to approach the black hole? Gas easil…
The afterglow, the redshift, and the extreme energetics of the gamma-ray burst 990123
S. R. Kulkarni, S. G. Djorgovski, S. C. Odewahn +26
Afterglow, or long-lived emission, has now been detected from about a dozen well-positioned gamma-ray bursts. Distance determinations made by measuring optical emission lines from…
Radio Structures of Seyfert Galaxies. VIII. A Distance and Magnitude Limited Sample of Early-Type Galaxies
Neil M. Nagar, Andrew S. Wilson, John S. Mulchaey +1
The VLA has been used at 3.6 and 20 cm to image a sample of about 50 early-type Seyfert galaxies with recessional velocities less than 7,000 km/s and total visual magnitude less th…
