Hubble and Spitzer Observations of an Edge-on Circumstellar Disk around a Brown Dwarf
K. L. Luhman, Lucia Adame, Paola D'Alessio +7
We present observations of a circumstellar disk that is inclined close to edge-on around a young brown dwarf in the Taurus star-forming region. Using data obtained with SpeX at the…
An HST Search for Substellar Companions in the Young Cluster IC 348
K. L. Luhman, K. K. McLeod, N. Goldenson
We present the results of a HST WFPC2 search for substellar companions to members of the star-forming cluster IC 348. The detection limits for companions to low-mass stars and brow…
The Far-Infrared Spectral Energy Distributions of X-ray-selected Active Galaxies
J. Kuraszkiewicz, B. J. Wilkes, E. J. Hooper +11
[Abridged] We present ISO far-infrared (IR) observations of 21 hard X-ray selected AGN from the HEAO-1 A2 sample. We compare the far-IR to X-ray spectral energy distributions (SEDs…
NICMOS Observations of Low-Redshift Quasar Host Galaxies
K. K. McLeod, B. A. McLeod
We have obtained Near-Infrared Camera and Multi-Object Spectrometer images of 16 radio quiet quasars observed as part of a project to investigate the ``luminosity/host-mass limit.'…
Infrared Properties of High Redshift and X-ray Selected AGN Samples
Belinda J. Wilkes, Eric J. Hooper, Kim K. McLeod +7
The NASA/ISO Key Project on active galactic nuclei (AGN) seeks to better understand the broad-band spectral energy distributions (SEDs) of these sources from radio to X-rays, with…
An Optical Study of BG Geminorum: An Ellipsoidal Binary with an Unseen Primar Star
P. J. Benson, A. Dullighan, A. Bonanos +2
We describe optical photometric and spectroscopic observations of the bright variable BG Geminorum. Optical photometry shows a pronounced ellipsoidal variation of the K0 I secondar…
The ISO/NASA Key Project on AGN Spectral Energy Distributions (Characteristics of the ISO Data)
Eric J. Hooper, Belinda J. Wilkes, Kim K. McLeod +5
The U.S. ISO Key Project on quasar spectral energy distributions seeks to better understand the very broad-band emission features of quasars from radio to X-rays. A key element of…
The Far-infrared Continuum of Quasars
Belinda J. Wilkes, Eric J. Hooper, Kim K. McLeod +5
ISO provides a key new far-infrared window through which to observe the multi-wavelength spectral energy distributions (SEDs) of quasars and active galactic nuclei (AGN). It allows…
The U.S. ISO Key Project on Quasars
Eric Hooper, Belinda Wilkes, Kim McLeod +5
Observations for the U.S. key project on quasars using ISO were completed in April when the satellite's cryogen supply expired. This proceeding presents an update of the project, i…
Near-IR Properties of Quasar Host Galaxies
K. K. McLeod
We have obtained deep, near-IR images of nearly 100 host galaxies of nearby quasars and Seyferts. We find the near-IR light to be a good tracer of luminous mass in these galaxies.…
Optical Detection of the Hidden Nuclear Engine in NGC~4258
Belinda J. Wilkes, Gary D. Schmidt, Paul S. Smith +2
The sub-parsec masing disk recently found to be orbiting a central mass of ~\msun\ in the Seyfert/LINER galaxy NGC~4258 provides the most compelling evidence to…
