Chandra Observations of Extended X-ray Emission in Arp 220
J. C. McDowell, D. L. Clements, S. A. Lamb +7
We resolve the extended X-ray emission from the prototypical ultraluminous infrared galaxy Arp 220. Extended, faint edge-brightened, soft X-ray lobes outside the optical galaxy are…
Chandra Observations of Arp 220: The Nuclear Source
D. L. Clements, J. C. McDowell, S. Shaked +5
We present the first results from 60ks of observations of Arp 220 using the ACIS-S instrument on Chandra. We report the detection of several sources near the galaxy's nucleus, incl…
The Multitude of Unresolved Continuum Sources at 1.6 microns in Hubble Space Telescope images of Seyfert Galaxies
A. C. Quillen, Colleen McDonald, A. Alonso-Herrero +4
We examine 112 Seyfert galaxies observed by the Hubble Space Telescope (HST) at 1.6 microns. We find that ~50% of the Seyfert 2.0 galaxies which are part of the Revised Shapeley-Am…
The Variability of Seyfert 1.8 and 1.9 Galaxies at 1.6 microns
A. C. Quillen, Shanna Shaked, A. Alonso-Herrero +4
We present a study of Seyfert 1.5-2.0 galaxies observed at two epochs with the Hubble Space Telescope (HST) at 1.6 microns. We find that unresolved nuclear emission from 9 of 14 nu…
