The Radio Continuum Morphology of Spiral Galaxies
Annual Review of Astronomy and Astrophysics, 1976Once Jansky realized that the extraterrestial microwave radiation which he had discovered was not coming from the Sun but from a direction near to that of the Galactic center (Jansky 1933) and after he established that the emission was associated with the Milky Way (Jansky 1935), he naturally concluded that either stars in the disk or interstellar ...

The ultraviolet continuum emission of radio galaxies
AIP Conference Proceedings, 1997This poster presents the UV continuum emission (in the range from 1400 to 3700 A) of radio galaxies (with redshift ranging from 0.01 to 0.1 and radio powers ranging from 1025 to 1027 Watts/Hz). The sample of radio galaxies were compiled by searching the Hubble Space Telescope (HST) archives for images taken with the Faint Object Camera (FOC) prior to ...

The radio continuum emission from the Galaxy
Symposium - International Astronomical Union, 1964Study of the radio continuum emission from the Galaxy is of interest both from the viewpoint of the physics of the radiating processes and the light which these shed on physical conditions within the Galaxy, and also because the large-scale organization of the emitting regions gives information about the structure of the Galaxy as a whole.

Continuum radio emission from Virgo galaxies
Publications of the Astronomical Society of the Pacific, 1988The paper presents single-antenna measurements of radio emission from 120 galaxies in the Virgo cluster at 2380 MHz using a 2.6 arc min beam (half-power beam width). It also presents interferometric measurements at the same frequency for 48 galaxies with less than or equal to 1 arc sec resolution.

Radio continuum of galaxies with H2O megamaser disks
Proceedings of the International Astronomical Union, 2017AbstractIn our attempt to investigate the basic active galactic nucleus (AGN) paradigm requiring a centrally located supermassive black hole (SMBH), a close to Keplerian accretion disk and a jet perpendicular to its plane, we have searched for radio continuum in galaxies with H2O megamasers in their disks.

Radio Continuum Emission from Galaxies
1975The continuum radio emission detected from external galaxies is produced either by thermal process or by the synchrotron process with the latter dominating in most cases. For the synchrotron process the volume emissivity is given by $$ \varepsilon \left( \upsilon \right) = {\rm{n}}{\mkern 1mu} {{\rm{B}}^{\frac{{{\rm{1 + }}\gamma }}{2}}} {\upsilon ^{

Radio Continuum Emission from Sculptor Galaxies
Publications of the Astronomical Society of Australia, 1986AbstractThe five major members of the Sculptor Group of galaxies and NGC 45 have been observed with the Molonglo observatory synthesis telescope. NGC 247 and NGC 300 were not detected and upper limits to their 843 MHz flux densities are given. Radio emission from NGC 7793 is discussed with particular attention to its morphology, radial dependence ...

Properties of the Radio Continuum Emission from Interacting Galaxies
Nature, 1973SEVERAL interacting galaxies have been observed recently in different programmes using the Westerbork Synthesis Radio Telescope at 21 cm wavelength (beamwidth 24 s × 24 s cosec δ). We give here a compilation of the data in order to examine the morphology, strength, and the frequency of occurrence of the radio emission from these interacting systems.

Origin of the Continuum in High Redshift Radio Galaxies
1999Deep Keck spectropolarimetry has been obtained of 9 high redshift radio galaxies (HzRGs) with z~2.5. All objects exhibit a remarkably similar continuum shape with a flattening around 1400A and a dip around 2200A (other results are in Fosbury et al. 1999). This can be explained by a simple ’scattering sphere’ model in which standard Galactic dust grains

Radio Continuum and CO emission in spiral galaxies
2023We have studied the relationship between the Radio Continuum (RC) and CO emission for a set of galaxies selected from the BIMA SONG sample. By combining new 20 cm VLA B-array observations with BIMA maps it has been possible to investigate the behaviour of the RC/CO correlation at matched resolution down to an angular size of about 6''.
