Using the Very Large Array, we have detected weak OH maser emission near the Turner-Welch protostellar source in the W3 OH region. Unlike typical interstellar OH masers, which are associated with ultracompact H II regions, our measured positions and proper motions (from very long baseline interferometry) indicate that these OH masers are associated with a bipolar outflow traced by strong H2O masers. These OH masers may be part of a class of interstellar OH masers that are associated with very…

Large Magnetic Fields and Motions of OH Masers in W75N

We report on a second epoch of VLBA observations of the 1665 and 1667 MHz OH masers in the massive star-forming region W75N. We find evidence to confirm the existence of very strong (~40 mG) magnetic

A survey for ground-state OH masers towards a sample of Herbig–Haro objects

Herbig-Haro objects are regions of shocked gas and dust which are produced when collimated outflows from a protostar interact with the surrounding dense gas. They have many similarities to supernova

OH 1720-MHz lines as tracers of bipolar outflows in the vicinity of Class I methanol masers

A sample of Class I methanol masers (MMI) has been surveyed at 1720 MHz to search for possible associations between MMI and 1720-MHz OH masers, which should be formed by the same collisional pumping

Very compact radio emission from high-mass protostars I. CRL 2136: Continuum and water maser observations

We report 5–43 GHz radio observations of the CRL 2136 region at $0\farcs6$–$6''$ resolution. We detect weak (mJy intensity) radio emission from the deeply embedded high-mass protostar IRS 1, which

Disks and Outflows in the Massive Protobinary System W3(OH)TW

Groundstate OH masers associated with Herbig-Haro objects

Abstract Jets from newly-formed stars plow into the surrounding ISM, creating nebulous regions known as Herbig-Haro (HH) objects. Signatures of C-type shocks have been found in many HH objects.

Search for Collisionally Pumped 1720 MHz OH Masers in Star-forming Regions: A VLA Survey of 18 cm OH Masers toward 80 Class I Methanol Masers

Class I methanol masers (cIMMs) and 1720 MHz OH masers are believed to arise from a common collisional pumping mechanism, and both trace shocked gas regions in supernova remnants (SNRs). However,

A Survey and Statistics of Interstellar OH and H 2 O Masers

We present a statistical analysis of a sky survey of interstellar H 2 O and OH masers. These masers can be classified into three categories: isolated H 2 O masers, isolated OH masers, and simple OH/H
