MERLIN 6 - GHz maser emission from W 3 ( OH )
We present the preliminary results of the first alignment to milliarsecond accuracy of the 6-GHz maser emission in OH and methanol maser lines toward W3(OH). The identifications of Zeeman pairs allowed us to infer the actual velocity of the OH material and the magnetic field strength at the location where 6.7-GHz methanol maser emission arises.
متن کاملExtended OH(1720 MHz) Maser Emission from Supernova Remnants
Compact OH(1720 MHz) masers have proven to be excellent signposts for the interaction of supernova remnants with adjacent molecular clouds. Less appreciated has been the weak, extended OH(1720 MHz) emission which accompanies strong compact maser sources. Recent single-dish and interferometric observations reveal the majority of maser-emitting supernova remnants(SNRs) have accompanying regions o...
متن کاملDiscovery of pulsed OH maser emission stimulated by a pulsar.
Stimulated emission of radiation has not been directly observed in astrophysical situations up to this time. Here we demonstrate that photons from pulsar B1641-45 stimulate pulses of excess 1720-megahertz line emission in an interstellar hydroxyl (OH) cloud. As this stimulated emission is driven by the pulsar, it varies on a few-millisecond time scale, which is orders of magnitude shorter than ...
متن کاملVLBA polarization observations of the J=7/2, 13.44 GHz OH maser in W3(OH)
We have obtained the first polarization images of the J = 7/2, F = 4−4 OHmaser emission fromW3(OH) at 13.44 GHz with high dynamic range and resolution. The emission has been imaged with a spectral resolution of 0.087 km s−1 and with a spatial resolution of 670μarcsec, the highest ever achieved in any image of the OH radical. The 13.44 GHz OH maser emission lies within an extremely compact area ...
متن کاملSpace - VLBI observations of OH maser OH 34 . 26 + 0 . 15 : low interstellar scattering
We report on the first space-VLBI observations of the OH34.26+0.15 maser in two main line OH transitions at 1665 and 1667 MHz. The observations involved the space radiotelescope on board the Japanese satellite HALCA and an array of ground radio telescopes. The map of the maser region and images of individual maser spots were produced with an angular resolution of 1 milliarcsec which is several ...
