Science with an ngVLA: Radio Recombination Lines from HII Regions
Dana S. Balser, L. D. Anderson, T. M. Bania +4
The ngVLA will create a Galaxy-wide, volume-limited sample of HII regions; solve some long standing problems in the physics of HII regions; and provide an extinction-free star form…
Ammonia in the hot core W51-IRS2: 12 new maser lines and a maser component with a velocity drift
C. Henkel, T. L. Wilson, H. Asiri +1
With the 100-m telescope at Effelsberg, 19 ammonia (NH3) maser lines have been detected toward the prominent massive star forming region W51-IRS2. Eleven of these inversion lines,…
The detection of the (J,K)=(18,18) line of NH3
T. L. Wilson, C. Henkel, S. Huettemeister
The first astronomical detection of the metastable () = (18,18) line of NH3 is reported. With 3130 K above the ground state, this is the NH3 line with by far the highest energ…
2mm Wavelength VLBI of SiO Masers and AGN
S. Doeleman, R. Phillips, A. Rogers +21
In April 2002 an array of antennas operating at 129GHz successfully detected VLBI fringes on both continuum AGN and SiO maser sources. The 129GHz fringes on maser sources represent…
VLBI observations at 147 GHz: first detection of transatlantic fringes in bright AGN
T. P. Krichbaum, D. A. Graham, W. Alef +21
At 147 GHz (2mm wavelength), we detected three prominent AGN (NRAO150, 3C279, 1633+382) with Very Long Baseline Interferometry (VLBI) with an angular resolution of only 18 micro-ar…
