We report the most complete analysis to date of observations of the Cosmic Microwave Background (CMB) obtained during the 1998 flight of BOOMERANG. We use two quite different metho…
Optical and Near-Infrared Spectroscopy of a High-Redshift, Hard X-ray Emitting Spiral Galaxy
Steve Dawson, Nate McCrady, Daniel Stern +4
We present optical and near-infrared Keck spectroscopy of CXOHDFN J123635.6+621424 (hereafter HDFX28), a hard X-ray source at a redshift of z = 2.011 in the flanking fields of the…
The Inner Rings of Beta Pictoris
Z. Wahhaj, D. W. Koerner, M. E. Ressler +3
We present Keck images of the dust disk around Beta Pictoris at 17.9 microns that reveal new structure in its morphology. Within 1" (19 AU) of the star, the long axis of the dust e…
The Discovery of H2O Maser Emission in Seven AGN and at High Velocities in the Circinus Galaxy
L. J. Greenhill, P. T. Kondratko, J. E. J. Lovell +4
We report the discovery of H2O maser emission at 1.35 cm wavelength in seven active galactic nuclei (at distances up to <80 Mpc) during a survey conducted at the 70-m diameter ante…
Shaping Proto-Planetary and Young Planetary Nebulae with Collimated Fast Winds
Chin-Fei Lee, Raghvendra Sahai
Using two-dimensional hydrodynamical simulations, we investigate the interaction of a collimated fast wind (CFW) interacting with a spherical asymptotic giant branch (AGB) wind as…
Results from a Complete Chandra Survey of Radio Jets
D. A. Schwartz, H. L. Marshall, B. P. Miller +7
We report preliminary results from the first targets observed as part of a program to image the X-ray jets in a complete sample of radio selected jets. We have acquired Australian…
Structure of the Mid-Infrared Emitting Disk Around WL16
Michael E. Ressler, Mary Barsony
WL16 is a unique member of the embedded young stellar population in the nearby rho Ophiuchi cloud core: its extended (900 AU diameter), high surface brightness disk is visible only…
The Magnetic Field in the Convection Zone
Alberto Bigazzi, Alexander A. Ruzmaikin
One of the key questions in solar physics that remains to be answered concerns the strength and the distribution of the magnetic fields at the base of the convection zone. The flux…
Detecting gravitational waves from precessing binaries of spinning compact objects: Adiabatic limit
Alessandra Buonanno, Yanbei Chen, Michele Vallisneri
Black-hole (BH) binaries with single-BH masses m=5--20 Msun, moving on quasicircular orbits, are among the most promising sources for first-generation ground-based gravitational-wa…
The Spectral Correlation Function of Molecular Clouds: A Statistical Test for Theoretical Models
Paolo Padoan, Alyssa Goodman, Mika Juvela
We compute the spectral correlation function (SCF) of 13CO J=1--0 maps of molecular cloud complexes. The SCF is a power law over approximately an order of magnitude in spatial sepa…
