Observations of the W49A North star-forming region in the J = 2-1 line of CS have been made with the BIMA array with an angular resolution of 46 × 38; complementary observations in the J = 2-1 line of C18O and J = 3-2 line of C34S were made with the

Publikováno v: Astrophysical Journal, 486(1), 329-337. IOP PUBLISHING LTD

Three hydrogen recombination lines-H90 alpha at 8.9 GHz, H92 alpha at 8.3 GHz, and H109 alpha at 5.0 GHz-have been observed with the Australia Telescope Compact Array toward the 30 Doradus Nebula, the giant H II region in the Large Magellanic Cloud.

High‐Resolution Observations of HiZeeman Absorption toward DR 21

Autor: D. A. Roberts, Hélène R. Dickel, W. M. Goss

Publikováno v: The Astrophysical Journal. 476:209-220

DR 21 has been imaged in H I at high resolution (~5'') in both left and right circular polarization with the VLA. The continuum emission is nearly totally absorbed with opacities > 5 over about 20 km s-1; the FWHM line width is unusually large (~35 k

Publikováno v: The Astrophysical Journal. 475:L57-L60

BIMA Array observations of the 107 GHz CH3OH masers in the Cep A star-forming region have been carried out with 2'' resolution. These are the first interferometric observations of 107 GHz CH3OH masers. Two masers were observed. They are both projecte

We present an interferometric search for large molecules, including methanol, methyl cyanide, ethyl cyanide, ethanol, and methyl formate in comets LINEAR (C/2002 T7) and NEAT (C/2001 Q4) with the Berkeley-Illinois-Maryland Association (BIMA) array. I

W49A North - Global or Local or No Collapse?

Autor: John A. Williams, Hélène R. Dickel, Lawrence H. Auer

We attempt to fit observations with 5" resolution of the J=2-1 transition of CS in the directions of H II regions A, B, and G of W49A North as well as observations with 20" resolution of the J=2-1, 3-2, 5-4, and 7-6 transitions in the directions of H
