Radio Continuum Surveys of the Galaxy and Galaxies [PDF]
Symposium - International Astronomical Union, 2002 Radio sky surveys give us basic information about the origin of the radio emission from the Galaxy. By mapping the sky at several radio frequencies a separation of the thermal and non-thermal emission components is possible. The major part of the low-frequency radio emission comes from the synchrotron process, the braking of relativistic electrons in ...

Jet Directions in Seyfert Galaxies: Radio Continuum Imaging Data [PDF]
The Astrophysical Journal Supplement Series, 2001 We present the results of VLA A-array 8.46 GHz continuum imaging of 55 Seyfert galaxies (19 Seyfert 1's and 36 Seyfert 2's). These galaxies are part of a larger sample of 88 Seyfert galaxies, selected from mostly isotropic properties, the flux at 60 mum and warm infrared 25 mum to 60 mum colors. These images are used to study the structure of the radio

CO in the Bipolar Radio Continuum Galaxy NGC 3367 [PDF]
The Astronomical Journal, 2005 CO emission has been imaged at 2" resolution in the central 10 kpc of the barred spiral galaxy NGC 3367. This galaxy has bipolar synchrotron lobes out to a radii of 6 kpc, straddling the compact nucleus. The peak molecular emission is in a source of radius 2" (425 pc) centered on the galaxy nucleus.

Radio continuum polarimetric imaging of high redshift radio galaxies
The Astronomical Journal, 1994 Multifrequency images of total and polarized radio continuum emission from the two high redshift radio galaxies 0902+343 (z = 3.40) and 0647+415 (4C 41.17, z = 3.80) are presented. These images represent the most sensitive polarimetric study of high redshift ratio galaxies to date.

Radio-continuum emission from quasar host galaxies
The Astronomical Journal, 1987 Seven low-redshift quasars that are likely to be in spiral galaxies have been observed in a search for radio-continuum emission from the host galaxies of quasars. The properties of the individual quasars are listed, and 1.49 GHz contour maps of the seven quasar fields are presented.

Radio Continuum Maps of Southern Barred Spiral Galaxies [PDF]
International Astronomical Union Colloquium, 1996 AbstractA sample of southern spiral galaxies are being observed at 20 and 13 cm with the Australia Telescope Compact Array in order to look for examples of anomalous outflows from the nuclear region. In this paper we discuss the radio continuum maps of the three barred spiral galaxies observed to date.

Radio continuum emission in ring galaxies
The Astronomical Journal, 1980 Radio emission was found in two (Arp 118 and Arp 148) of 27 ring-type galaxies searched with the NRAO interferometer to a detection limit of about 10 mJy at 11.1 cm. These two were also observed at 6 cm with the higher sensitivity and resolution of the VLA.
