The Astronomical Journal, 2023 We report VLA B-configuration observations of the H i 21 cm line on the close disk galaxy pair NGC 5595 and NGC 5597. At the angular resolution of the observations, ∼7.″1 × 4.″2, while most of the H i 21 cm in NGC 5595 and NGC 5597 has the same extent as

First Detection of Radio Emission Associated with a Classical Cepheid
The Astronomical Journal, 2023 We report the detection of 15 GHz radio continuum emission associated with the classical Cepheid variable star δ Cephei ( δ Cep) based on observations with the Karl G. Jansky Very Large Array.

Multifrequency radio observations of SNR J0536-6735 (N 59B) with associated pulsar [PDF]
Serbian Astronomical Journal, 2012 We present a study of new Australian Telescope Compact Array (ATCA) observations of supernova remnant, SNR J0536-6735. This remnant appears to follow a shell morphology with a diameter of D=36x29 pc (with 1 pc uncertainty in each direction ...

Radio continuum emission of the Milky Way and nearby galaxies [PDF]
Symposium - International Astronomical Union, 1985 The radio continuum emission of the Milky Way and nearby galaxies can be decomposed into a central region, a clumpy “thin disk”, concentrated in the spiral arms, and a smooth “thick disk” (or flattened “halo”). The emissivity ratio of the two disks seems to be related to the magnetic field properties: Galaxies with strong radio spiral arms reveal a ...

Radio Continuum Emission in Polar Ring Galaxies
The Astronomical Journal, 2004 We have used the Very Large Array aperture synthesis telescope to conduct a radio continuum survey of polar-ring galaxies, at 20cm and 6cm. Forty objects were observed at 20cm with 5" resolution. Twenty (50%) of the program sources were detected at 20cm, down to our 5-sigma limit of 0.5 mJy/beam.

The Astrophysical Journal, 2023 We present polarization-sensitive images from the Karl G. Jansky Very Large Array (VLA) at 5 GHz of 11 radio-quiet PG quasars. Based on the radio morphology, spectral index, and polarization properties from the VLA study, coupled with the findings of our

Study of nonthermal continuum patches : wave propagation and plasmapause study [PDF]
, 2011 Nonthermal continuum (NTC) radiation is believed to be emitted at the plasmapause and near the magnetic equator. We present a particular type of NTC radiation, referred to as NTC patch, which appears over a wide frequency range and within a relatively ...

Observations of Radio Continuum Emission from M 31 [PDF]
Symposium - International Astronomical Union, 1970 Observations of continuum emission from M 31 have been made with the Cambridge One-mile radio telescope (Pooley, 1969). Two observing frequencies were used; maps of the whole of the visible nebula were obtained at 408 MHz, and spectral data for the central region at 1407 MHz.

Baldwin Effect and Additional BLR Component in AGN with Superluminal Jets
Frontiers in Astronomy and Space Sciences, 2016 We study the Baldwin Effect (BE) in 96 core-jet blazars with optical and ultraviolet spectroscopic data from a radio-loud AGN sample obtained from the MOJAVE 2cm survey.

Evidence for Low-power Radio Jet–ISM Interaction at 10 pc in the Dwarf AGN Host NGC 4395
The Astrophysical Journal, 2023 Black-hole-driven outflows in galaxies hosting active galactic nuclei (AGN) may interact with their interstellar medium (ISM) affecting star formation (SF).
