Supersonic water masers in 30 Doradus [PDF]

, 2000
We report on extremely high velocity molecular gas, up to -80 km/s relative to the ambient medium, in the giant star-formation complex 30 Doradus in the Large Magellanic Cloud (LMC), as observed in new 22 GHz H2O maser emission spectra obtained with the ...

Multiwavelength observations of the supernova remnant G349.7+02 interacting with a molecular cloud

, 2010
We present molecular-line observations at millimetre, centimetre and infrared wavelengths of the region containing OH(1720 MHz) masers in the supernova remnant (SNR) G349.7+0.2, using the Australia Telescope (AT) Mopra antenna, the Swedish-ESO ...

Circular Polarization of Water Masers in the Circumstellar Envelopes of Late Type Stars [PDF]

, 2002
We present circular polarization measurements of circumstellar H_2O masers. The circular polarization detected in the (6_{16}-5_{23}) rotational transition of the H_{2}O maser can be attributed to Zeeman splitting in the intermediate temperature and ...

A survey of SiO emission towards interstellar masers [PDF]

Astronomy and Astrophysics Supplement Series, 1998
We have conducted a survey of SiO emission to- wards galactic H2O and OH masers and ultracompact HII regions using the 15-m SEST and the 20-m Onsala tele- scope. With the SEST the transitions (v =0 ;J =2 1) and (v =0 ;J =3 2) of SiO at 3 and 2 mm were measured simultaneously. With Onsala only the (v =0 ;J =2 1) line was accessible.

Magnetic field in Cepheus A as deduced from OH maser polarimetric observations

, 2005
We present the results of MERLIN polarization mapping of OH masers at 1665 and 1667 MHz towards the Cepheus A star-forming region. The maser emission is spread over a region of 6 arcsec by 10 arcsec, twice the extent previously detected.

Parsec-scale magnetic fields in Arp 220 [PDF]

, 2014
We present the first very-long-baseline interferometry (VLBI) detections of Zeeman splitting in another galaxy. We used Arecibo Observatory, the Green Bank Telescope, and the Very Long Baseline Array to perform dual-polarization observations of OH maser ...

Circumstellar masers in the Magellanic Clouds

, 2001
We have searched for 22 GHz H2O and 43/86/129 GHz SiO masers in bright IRAS point sources in the SMC and LMC, to test whether the kinematics of the mass loss from these stars depends on metallicity.
