Detection of rest-frame optical lines from x-shooter spectroscopy of weak emission-line quasars
(The American Astronomical Society, 2015-06-01)
Over the past 15 yr, examples of exotic radio-quiet quasars with intrinsically weak or absent broad emission line
regions (BELRs) have emerged from large-scale spectroscopic sky surveys. Here, we present spectroscopy ...
Vla observations of carbon radio recombination lines toward the H II region complex S88B
(1998-07-10)
We present high angular resolution VLA observations of the C92a, C110a, and C166a radio recombination
lines of carbon from the region of massive star formation known as S88B. The observations
reveal that the carbon ...
The radio structure of the narrow-line Seyfert 1 Mrk 783 with VLBA and e-MERLIN
(Oxford University Press, 2020)
In this paper, we present the analysis of new radio and optical observations of the narrow-line Seyfert 1 galaxy Mrk 783. 1.6 GHz
observations performed with the e-MERLIN interferometer confirm the presence of the diffuse ...
Large scale map of millimeter wavelength hydrogen radio recombination lines around a young massive star cluster
(IOP Publishing Ltd, 2017)
We report the first map of large-scale (10 pc in length) emission of millimeter-wavelength hydrogen recombination lines (mm-RRLs) toward the giant H II region around the W43-Main young massive star cluster (YMC). Our mm-RRL ...
Continuum observations at 3 and 12 mm of the high-mass protostellar jet iras 16547_4247
(2007-11-01)
Continuumdata at 25 and 88 GHz toward the luminous young stellar object IRAS 16547 4247 (G343.126 0.062)
have been obtained with the Australia Telescope Compact Array. The triple emission source identified previously ...
The State-of-Play of Anomalous Microwave Emission (AME) research
(Elsevier B.V., 2018)
Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation observed at frequencies in the range ≈ 10–60 GHz. AME was first detected in 1996 and recognised as an additional component of emission in 1997. ...
Two massive star-forming regions at early evolutionary stages
(2002-11-10)
We report sensitive Australia Telescope Compact Array radio continuum observations toward IRAS
15596 5301 and 16272 4837, two luminous objects (L > 2 104 L ) thought to represent massive starforming
regions in early ...
Spatially resolved HCN J = 4-3 and CS J = 7-6 emission from the disk around HD 142527
(The American Astronomical Society, 2014-09-10)
The disk around HD 142527 attracts a great amount of attention compared to others because of its resolved
(sub-)millimeter dust continuum that is concentrated into the shape of a horseshoe toward the north of the star. ...
Simba observations of the keyhole nebula
(2005-11-20)
We report observations made with the SIMBA bolometer at SEST to measure the 1.2 mm continuum emission
toward the Keyhole nebula. We have detected 1.2 mm emission toward the ionized gas filaments of the Car II radio
source ...
The atomic gas of star-forming galaxies at z similar to 0.05 as revealed by the Five-hundred-meter Aperture Spherical Radio Telescope
(EDP Science, 2020)
Context. We report new HI observations of four z similar to 0.05 VALES galaxies undertaken during the commissioning phase of the Five-hundred-meter Aperture Spherical Radio Telescope (FAST).Aims. FAST is the largest ...
