maser

Converse of object

call: These beacons, called masers ( the radio equivalent of lasers ) show up as bright spots in the radio images.

Preposition: in

region: Abstract This thesis presents observational data and analysis of the OH masers in the star-forming region W3(OH ).

Adjective modifier

• oh: The astrometric precision will also enable proper motion studies, and accurate comparisions of OH masers with methanol, water and other species.
• cosmic: In 1965 the first cosmic maser was discovered, in a region of OH gas close to a young star.

Modifies a noun

• emission: It will be used to survey our Galaxy for sources of maser emission, the ( natural ) radio equivalents of lasers.
• source: The main research aims include a survey searching for new maser sources in the Galaxy and monitoring the variability of known sources.
• datum: The epoch 1 and 2 H 2 O maser data has been largely reduced.
• action: One possible application is the initiation of maser action, where the radiation intensity is very low.

Noun used with modifier

• methanol: Until now methanol masers have been found only in association with massive young stellar objects.
• hydrogen: In this way the frequency of the transition observed in the fountain can be related to that of the hydrogen maser.
• water: We have obtained 6 epochs of VLBA 22 GHz water maser data, monitoring the masers around the pulsating evolved star U Orionis.
• O: The epoch 1 and 2 H 2 O maser data has been largely reduced.
• oh: In it I used both VLBA and MERLIN observations to study circumstellar masers and did theoretical modeling of both water and OH masers.
