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).

Radio-continuum emission from the young galactic supernova remnant G1.9+0.3 [PDF]
Serbian Astronomical Journal, 2014 We present an analysis of a new Australia Telescope Compact Array (ATCA) radio-continuum observation of supernova remnant (SNR) G1.9+0.3, which at an age of ~181±25 years is the youngest known in the Galaxy.

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.

SYNCHROTRON EMISSION FROM THE GALACTIC HI LAYER [PDF]
Journal of Astronomy and Space Sciences, 2007 The relationship between the Galactic magnetic field strength and the gas density has been revisited. A synchrotron continuum emission data at 408 MHz and HI column density provide a good data for such study.

Broadband VLA Spectral-line Survey of a Sample of Ionized Jet Candidates
The Astrophysical Journal Supplement Series, 2023 The study of the interaction between ionized jets, molecular outflows, and their environments is critical to understanding high-mass star formation, especially because jets and outflows are thought to be key in the transfer of angular momentum outward ...

Examining the Seyfert - Starburst Connection with Arcsecond Resolution Radio Continuum Observations [PDF]
Astron.J.131:701-715,2006, 2005 We compare the arcsecond-scale circumnuclear radio continuum properties between five Seyfert and five starburst galaxies, concentrating on the search for any structures that could imply a spatial or causal connection between the nuclear activity and a circumnuclear starburst ring.

Radio Continuum Spectra of Planetary Nebulae
Galaxies, 2018 Radio continuum emission of planetary nebulae is a rich source of information about their structure and physical parameters. Although radio emission is well studied, planetary nebulae show higher spectral indices than expected for homogeneous sphere.

The Astrophysical Journal, 2023 We present a case study of HE 0040-1105, an unobscured radio-quiet active galactic nucleus (AGN) at a high accretion rate of λ _Edd = 0.19 ± 0.04. This particular AGN hosts an ionized gas outflow with the largest spatial offset from its nucleus compared ...

Variable emission mechanism of a Type IV radio burst [PDF]
A&A 623, A63 (2019), 2019 Context. The Sun is an active star and the source of the largest explosions in the solar system, such as flares and coronal mass ejections (CMEs). Flares and CMEs are powerful particle accelerators that can generate radio emission through various emission mechanisms. Aims.

The Astrophysical Journal, 2023 The conditions under which accreting neutron stars launch radio-emitting jets and/or outflows are still poorly understood. The ultracompact X-ray binary X1850–087, located in the globular cluster NGC 6712, is a persistent atoll-type X-ray source that has
