On the integrated continuum radio spectrum of supernova remnant W44 (G34.7-0.4): New insights from Planck [PDF]
Serbian Astronomical Journal, 2015 In this paper, the integrated continuum radio spectrum of supernova remnant (SNR) W44 was analyzed up to 70 GHz, testing the different emission models that can be responsible for its particular shape.

An Ionized Outflow in Orion-KL Source I?
The Astrophysical Journal, 2023 We present images at 6 and 14 GHz of Source I (SrcI) in the Kleinmann–Low Nebula in Orion. At higher frequencies, from 43 to 340 GHz, images of this source are dominated by thermal emission from dust in a 100 au diameter circumstellar disk, but at 6 and ...

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 ...

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).

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.
