Interferometric Observations of Redshifted Molecular Absorption toward Gravitational Lenses
We have made radioand millimeter-wavelength interferometric observations of a variety of molecular absorption lines toward the gravitational lens systems B0218+357 and PKS 1830−211. The absorption occurs in the lensing galaxies at redshifts of 0.685 and 0.89, respectively. The high spatial resolution of our VLA and VLBA observations allows imaging of the background continuum emission and the ab...
متن کاملMolecular gas in the elliptical galaxy NGC759 Interferometric CO observations
We present interferometric observations of CO(1–0) emission in the elliptical galaxy NGC759 with an angular resolution of 3 . ′′1×2 . ′′3 (990 × 735 pc at a distance of 66Mpc). NGC759 contains 2.4× 109 M of molecular gas. Most of the gas is confined to a small circumnuclear ring with a radius of 650 pc and with an inclination of 40◦. The maximum gas surface density in the ring is 750M pc−2. Alt...
متن کاملMolecular Line Observations of Proto-planetary Nebulae
We present our recent results on mm-wave CO observations of proto-planetary nebulae. These include high-resolution interferometric maps of various CO lines in three well known bipolar PPNe: M 1–92, M 2–56 and OH 231.8+4.2. The global properties of the high velocity molecular emission in post-AGB sources have been also studied, by means of high-sensitivity single dish observations of the J=1–0 a...
متن کاملMolecular line observations of southern S stars
We observed a sample of southern S stars with the SEST telescope, in the SiO (v=0, J=3-2) transition at 130.3 GHz, and the HCN (J=1-0) transition at 88.6 GHz. SiO emission was detected in all seven stars observed, while HCN was detected in two. We employed a statistical equilibrium/radiative transfer model to estimate the SiO abundance for an assumed molecular distribution. The inferred SiO abu...

We present interferometric observations of CO(1–0) emission in the elliptical galaxy NGC759 with an angular resolution of 3 . ′′1×2 . 3 (990×735pc at a distance of 66Mpc). NGC759 contains 2.4 × 10M⊙ of molecular gas. Most of the gas is confined to a small circumnuclear ring with a radius of 650pc with an inclination of 40. The maximum gas surface density in the ring is 750M⊙ pc . Although this ...
