Flux Densities and Radio Polarization Characteristics of Two Vela-like Pulsars
F. Crawford, C. L. Tiffany
We report on dual-frequency radio polarimetry observations of two young, energetic pulsars, PSRs J0940-5428 and J1301-6305. These were among the first Vela-like pulsars discovered…
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…
FIRST `Winged' and `X'-shaped Radio Source Candidates
C. C. Cheung, A. Springmann
A small number of double-lobed radio galaxies are found with an additional pair of extended low surface brightness `wings' of emission giving them a distinctive `X'-shaped appearan…
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…
A Photometric Study of Stars in the MBM 12 Association
William Herbst, Eric C. Williams, Wendy P. Hawley
We have monitored four fields containing nine previously identified members of the MBM 12 association to search for photometric variability and periodicity in these pre-main sequen…
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…
