A New Component in the Radio Continua of PNe
نویسندگان
چکیده
A byproduct of experiments designed to map the CMB is the recent detection of a new component of foreground galactic emission. The anomalous foreground at 10-30 GHz, unexplained by traditional emission mechanisms, correlates with 100 mum dust emission, and is thus presumably due to dust. Is the anomalous foreground ubiquitous in the Galaxy? I will present evidence obtained with the CBI and SIMBA+SEST supporting the existence of the new component in the ISM at large, and in specific objects, in the form of a 31 GHz excess over free-free emission in PNe.

Optical recombination lines as probes of conditions in planetary nebulae
Since the last IAU symposium on planetary nebulae (PNe), several deep spectroscopic surveys of the relatively faint optical recombination lines (ORLs) emitted by heavy element ions in PNe and H ii regions have been completed. New diagnostic tools have been developed thanks to progress in the calculations of basic atomic data. Together, they have led to a better understanding of the physical con...
متن کاملRadio Planetary Nebulae in the Magellanic Clouds
We report the extragalactic radio-continuum detection of 15 planetary nebulae (PNe) in the Magellanic Clouds (MCs) from recent Australia Telescope Compact Array+Parkes mosaic surveys. These detections were supplemented by new and high resolution radio, optical and IR observations which helped to resolve the true nature of the objects. Four of the PNe are located in the Small Magellanic Cloud (S...
متن کاملThe Σ − D Analysis of Recently Detected Radio Planetary Nebulae in the Magellanic Clouds ( Research Note )
Aims. To investigate and analyze the radio surface brightness to diameter (Σ− D) relation for recently detected, bright radio-continuum planetary nebulae (PNe) in the Magellanic Clouds (MC). Methods. We apply a Monte Carlo analysis in order to account for sensitivity selection effects on measured Σ − D relation slopes for bright radio PNe in the MCs. Results. In the Σ − D plane these radio MCs ...
متن کاملOptical Spectra of Radio Planetary Nebulae in the Small Magellanic Cloud
We present preliminary results from spectral observations of four (4) candidate radio sources co-identified with known planetary nebulae (PNe) in the Small Magellanic Cloud (SMC). These were made using the Radcliffe 1.9-meter telescope in Sutherland, South Africa. These radio PNe were originally found in Australia Telescope Compact Array (ATCA) surveys of the SMC at 1.42 and 2.37 GHz, and were ...
