Observations of extragalactic H2O masers in bright IRAS sources
We report the first results of an ongoing survey at 22GHz with the 100-m Effelsberg telescope to search for water maser emission in bright IRAS sources. We have detected water vapor emission in IC 342. The maser, associated with a star forming region ∼10–15 west of the nucleus, consists of a single 0.5 km s wide feature and reaches an isotropic luminosity of 10 L⊙ (D=1.8Mpc). Our detection rais...
متن کاملTracing the root of the bipolar jet in IRAS 20126+4104: VLBA observations of H2O masers
We present VLBA observations of the H2O masers towards IRAS 20126+4104, a high-mass young stellar object which is believed to be associated with a rotating disk and a bipolar outflow/jet system collimated along the disk axis. A model fit to the positions and velocities of the maser spots demonstrates that these could arise on a conical surface at the interface between the jet and the surroundin...
متن کاملThe magnetic field of IRAS 16293-2422 as traced by shock-induced H2O masers
Context. Shock-induced H2O masers are important magnetic field tracers of very high density gas. Water masers are found in both highand low-mass star-forming regions, and are a powerful tool for comparing magnetic field morphologies in both mass regimes. Aims. We present one of the first magnetic field determinations for the low-mass protostellar core IRAS 16293-2422 at volume densities as high...
متن کاملNew H2O masers in Seyfert and FIR bright galaxies
Using the Effelsberg 100-m telescope, detections of four extragalactic water vapor masers are reported. Isotropic luminosities are ∼50, 1000, 1, and 230 L⊙ for Mrk 1066 (UGC 2456), Mrk 34, NGC 3556, and Arp 299, respectively. Mrk 34 contains by far the most distant and one of the most luminous water vapor megamasers so far reported in a Seyfert galaxy. The interacting system Arp 299 appears to ...
متن کاملExtragalactic water masers in bright IRAS sources
We report the results of a search for 22GHz water maser emission in IRAS-bright galaxies, using the 100-m Effelsberg telescope. In particular, we present the details of four new maser detections (IC 342, NGC 2146, NGC 3556, and Arp 299) and follow-up interferometric studies. A comparison between water maser detection rates derived in the present study and those in previous similar surveys is al...
