Dynamics of Multi-Component, Multi-Field Quintessence
Tzihong Chiueh
Dynamics of the multi-component, multi-field quintessence and gravity is formulated as relativistic N-particle dynamics, embedded in a static viscus flat space and under the forces…
Hamiltonian Analysis of Poincaré Gauge Theory: Higher Spin Modes
H. J. Yo, J. M. Nester
We examine several higher spin modes of the Poincaré gauge theory (PGT) of gravity using the Hamiltonian analysis. The appearance of certain undesirable effects due to non-linear c…
Bias and Conditional Mass Function of Dark Halos Based on the Nonspherical Collapse Model
Lihwai Lin, Tzihong Chiueh, Jounghun Lee
Nonspherical collapse is modelled, under the Zeldovich approximation, by six-dimensional random walks of the initial deformation tensor field. The collapse boundary adopted here is…
Distorted HI Gas in the Widely Separated LIRG Arp 256
Jacqueline Chen, K. Y. Lo, Robert A. Gruendl +2
We present new interferometric HI and CO (1-0) observations of the luminous infrared source, Arp 256. Arp 256 consists of two spiral galaxies in an early stage of merging, with a p…
Detection of Galaxy Spin Alignments in the PSCz Shear Field
Jounghun Lee, Ue-Li Pen
We report the first direct observational evidence for alignment of galaxy spin axes with the local tidal shear field. We measure quantitatively the strength of this directional cor…
Heating and Ionization of X-Winds
H. Shang, A. E. Glassgold, F. H. Shu +1
In order to compare the x-wind with observations, one needs to be able to calculate its thermal and ionization properties. We formulate the physical basis for the streamline-by-str…
A numerical testbed for singularity excision in moving black hole spacetimes
H. J. Yo, T. W. Baumgarte, S. L. Shapiro
We evolve a scalar field in a fixed Kerr-Schild background geometry to test simple -dimensional algorithms for singularity excision. We compare both centered and upwind sche…
Abundant Molecular Gas in Tidal Dwarf Galaxies: On-going Galaxy Formation
J. Braine, P. -A. Duc, U. Lisenfeld +4
[Abridged...] We investigate the process of galaxy formation as can be observed in the only currently forming galaxies -- the so-called Tidal Dwarf Galaxies, hereafter TDGs -- thro…
Positional Coincidence between the High-latitude Steady Unidentified Gamma-ray Sources and Possibly Merging Clusters of Galaxies
Wataru Kawasaki, Tomonori Totani
We report an evidence for the first time that merging clusters of galaxies are a promising candidate for the origin of high galactic-latitude, steady unidentified EGRET gamma-ray s…
Infall, Outflow, Rotation, and Turbulent Motions of Dense Gas within NGC 1333 IRAS 4
James Di Francesco, Philip C. Myers, David J. Wilner +2
Millimeter wavelength observations are presented of NGC 1333 IRAS 4, a group of highly-embedded young stellar objects in Perseus, that reveal motions of infall, outflow, rotation,…
Molecular gas in nearby powerful radio galaxies
S. Leon, J. Lim, F. Combes +1
We report the detection of CO(1-0) and CO(2-1) emission from the central region of nearby 3CR radio galaxies (z 0.03). Out of 21 galaxies, 8 have been detected in, at least, one…
Circumnuclear Spiral Arms and Starburst Rings in Magnetized Barred Spiral Galaxies
Yu-Qing Lou, ZuHui Fan, Chi Yuan +1
The Seyfert galaxy NGC 1097 has an extended neutral hydrogen disk, a companion, a prominent bar and a luminous circumnuclear starburst "ring". Magnetic fields as revealed by nonthe…
Biomolecules in the Interstellar Medium and Comets
S. B. Charnley, S. D. Rodgers, Y-J. Kuan +1
We review recent studies of organic molecule formation in dense molecular clouds and in comets. We summarise the known organic inventories of molecular clouds and recent comets, pa…
The QSO - Ultraluminous Infrared Galaxies Connection
S. Veilleux, D. -C. Kim, D. B. Sanders
For the past several years, our group has pursued a vigorous ground-based program aimed at understanding the nature of ultraluminous infrared galaxies. We recently published the re…
Nature of widely separated ultraluminous infrared galaxies
Dinh-V-Trung, K. Y. Lo, D. -C. Kim +2
In the complete sample of ultraluminous infrared galaxies (ULIRGs) compiled by Kim (1995) about 5% consists of widely separated galaxies which are presumably in the early phase of…
Gas Distribution and Starburst Activity in the Widely Separated Interacting Galaxies NGC 6670
Wei-Hao Wang, K. Y. Lo, Yu Gao +1
We present high resolution H I 21 cm line, 20 cm radio continuum, and CO(1-0) line observations of the luminous infrared galaxy NGC 6670. NGC 6670 consists of two edge-on disk gala…
Submillimeter CO emission from shock-heated gas in the L1157 outflow
Naomi Hirano, Yoshiaki Taniguchi
We present the CO J=6-5, 4-3, and 3-2 spectra from the blueshifted gas of the outflow driven by the low-mass class 0 protostar in the L1157 dark cloud. Strong submillimeter CO emis…
Infrared Line Emission in the Interacting Region of Arp 244 (the Antennae): Colliding Molecular Cloud Complexes ?
M. C. Liang, T. R. Geballe, K. Y. Lo +1
We report velocity-resolved spectroscopy of infrared hydrogen recombination lines in the interacting region of the Antennae galaxies (NGC 4038/4039). It generally has been assumed…
Structure of Sagittarius A* at 86 GHz using VLBI Closure Quantities
S. S. Doeleman, Z. -Q. Shen, A. E. E. Rogers +9
At radio wavelengths, images of the compact radio source Sagittarius A* (Sgr A*) in the Galactic Center are scatter broadened with a lambda^2 dependence due to an intervening ioniz…
