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.

The influence of the cluster environment on the large-scale radio continuum emission of 8 Virgo cluster spirals [PDF]
, 2010 The influence of the environment on the polarized and total power radio continuum emission of cluster spiral galaxies is investigated. We present deep scaled array VLA 20 and 6 cm observations including polarization of 8 Virgo spiral galaxies. These data

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 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.

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 ...
