Molecular emission from the shocked bipolar outflow in OH 231 . 8 + 4 . 2

We present high-resolution observations of several molecular lines in OH231.8+4.2 taken with the IRAM interferometer. All molecules are distributed in a narrow region along the symmetry axis, and flow outwards following a velocity gradient similar to that found in CO. The HCO emission is found to be very clumpy and strongly enhanced in the shock-accelerated lobes, indicating that the formation ...

Shocked molecular hydrogen from RNO 91

We report the detection of the H2 v=1-0 S(1) line at 2.122μm, from RNO91 in the L43 dark cloud, which is known to be a T Tauri star surrounded by a 1700AU disk structure (containing ices) and a weak outflow. The non-detection of the H2 v=2-1 S(1) line at 2.247μm suggests shock excitation rather than fluorescence. The emission is extended spatially up to 9 in the north-south direction. The line ...

A SCUBA survey of the NGC 2068/2071 protoclusters

We report the results of a submillimeter dust continuum survey of the protoclusters NGC 2068 and NGC 2071 in Orion B carried out at 850μm and 450μm with SCUBA on JCMT. The mapped region is ∼ 32′×18′ in size (∼ 4 pc × 2 pc) and consists of filamentary dense cores which break up into small-scale (∼ 5 000 AU) fragments, including 70 starless condensations and 5 circumstellar envelopes/disks. The s...

Studying the galactic outflow in NGC 1569

We present deep WIYN Hα imaging of the dwarf irregular starburst galaxy NGC 1569, together with WIYN SparsePak spatially-resolved optical spectroscopy of the galactic outflow. This leads on from our previous detailed analyses of the state of the ISM in the central regions of this galaxy. Our deep imaging reveals previously undetected ionized filaments in the outer halo. Through combining these ...

Isocam Molecular Hydrogen Images of the Cep E Outflow

The physical characteristics of Cepheus E (Cep E) ‘embedded’ outflow are analyzed using ISOCAM images in the v=0-0 S(5) 6.91 μm and S(3) 9.66 μm molecular hydrogen lines. We find that the morphology of the Cep E outflow in the ground vibrational H2 lines is similar to that of the near infrared v=1-0 2.12 μm line. At these mid-IR wavelengths, we do not detect the second H2 outflow which is almos...
