Gauging the dark matter fraction in a S0 galaxy at z=0.47 through gravitational lensing from deep HST/ACS imaging
G. Covone, M. Paolillo, N. R. Napolitano +9
We analyze a new gravitational lens, OAC-GL J1223-1239, serendipitously found in a deep I-band image of the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS). The lens…
Interferometric Mapping of Magnetic Fields: The massive star forming region G34.4+0.23 MM
P. C. Cortes, R. M. Crutcher, D. Shepherd +1
We report millimeter interferometric observations of polarized continuum and line emission from the massive star forming region G34.4. Polarized thermal dust emission at 3 mm wavel…
GOODS 850-5 -- A z>4 Galaxy Discovered in the Submillimeter?
Wei-Hao Wang, Lennox L. Cowie, Jennifer van Saders +2
We report an SMA interferometric identification of a bright submillimeter source, GOODS 850-5. This source is one of the brightest 850 um sources in the GOODS-N but is extremely fa…
Geometrical tests of cosmological models. II. Calibration of rotational widths and disc scaling relations
A. Saintonge, K. L. Masters, C. Marinoni +3
This series of papers is dedicated to a new technique to select galaxies that can act as standard rods and standard candles in order to perform geometrical tests on large samples o…
Modeling Non-Circular Motions in Disk Galaxies: Application to NGC 2976
Kristine Spekkens, J. A. Sellwood
We present a new procedure to fit non-axisymmetric flow patterns to 2-D velocity maps of spiral galaxies. We concentrate on flows caused by bar-like or oval distortions to the tota…
Gravitational lensing by cosmic strings: what we learn from the CSL-1 case
M. V. Sazhin, O. S. Khovanskaya, M. Capaccioli +5
Cosmic strings were postulated by Kibble in 1976 and, from a theoretical point of view, their existence finds support in modern superstring theories, both in compactification model…
