Water vapor in the starburst galaxy NGC 253: A new nuclear maser?
C. Henkel, A. Tarchi, K. M. Menten +1
22 GHz water vapor emission was observed toward the central region of the spiral starburst galaxy NGC 253. Monitoring observations with the 100-m telescope at Effelsberg and measur…
Very compact radio emission from high-mass protostars. I. CRL 2136: Continuum and water maser observations
K. M. Menten, F. F. S. van der Tak
We report 5-43 GHz radio observations of the CRL 2136 region at 0.6-6 arcsec resolution. We detect weak (mJy intensity) radio emission from the deeply embedded high-mass protostar…
Extragalactic water masers in bright IRAS sources
A. Tarchi, C. Henkel, A. B. Peck +3
We report the results of a search for 22 GHz water maser emission in IRAS-bright galaxies, using the 100-m Effelsberg telescope. In particular, we present the details of four new m…
Molecular Gas in the Host Galaxy of a Quasar at Redshift z=6.42
Fabian Walter, Frank Bertoldi, Chris Carilli +7
Observations of the molecular gas phase in quasar host galaxies provide fundamental constraints on galaxy evolution at the highest redshifts. Molecular gas is the material out of w…
Interstellar Hydroxyl Masers in the Galaxy. II. Zeeman Pairs and the Galactic Magnetic Field
Vincent L. Fish, Mark J. Reid, Alice L. Argon +1
We have identified and classified Zeeman pairs in the survey by Argon, Reid, & Menten of massive star-forming regions with 18 cm (2 Pi 3/2, J = 3/2) OH maser emission. We have foun…
Discovery of a luminous water megamaser in the FRII radiogalaxy 3C403
A. Tarchi, C. Henkel, M. Chiaberge +1
We report the first detection of a water megamaser in a radio-loud galaxy, 3C403. This object has been observed as part of a small sample of FRIIs with evidence of nuclear obscurat…
