recommendations! Published in 2018 at "Space Science Reviews"

DOI: 10.1007/s11214-018-0498-1

Abstract: Very Long Baseline Interferometry (VLBI) is a differential technique observing radiation of compact extra-galactic radio sources with pairs of radio telescopes. For these observations, the frequency standards at the telescopes need to have very high… read more here.

DOI: 10.1017/pasa.2017.57

Abstract: Abstract We test the hypothesis that limitations in the sky model used to calibrate an interferometric radio telescope, where the model contains extended radio sources, will generate bias in the Epoch of Reionisation power spectrum.… read more here.

DOI: 10.1088/1674-4527/ad6c95

Abstract: Gravity as a fundamental force plays a dominant role in the formation and evolution of cosmic objects and leaves its effect in the emergence of symmetric and asymmetric structures. Thus, analyzing the symmetry criteria allows… read more here.

DOI: 10.1093/mnras/staa657

Abstract: We present optical and near-infrared imaging covering a $\sim$1.53 deg$^2$ region in the Super-Cluster Assisted Shear Survey (SuperCLASS) field, which aims to make the first robust weak lensing measurement at radio wavelengths. We derive photometric… read more here.

DOI: 10.1093/mnras/stac1034

Abstract: Radio continuum observations offer a new window on compact objects in globular clusters compared to typical X-ray or optical studies. As part of the MAVERIC survey, we have used the Australia Telescope Compact Array to… read more here.

DOI: 10.1093/mnras/stad1217

Abstract: The incidence of young but fading radio sources provides important information on the life cycle of radio emission in radio-loud active galactic nuclei. Despite its importance for constraining the models of radio source evolution, there… read more here.

DOI: 10.1093/mnras/staf1643

Abstract: This paper is the second in a series presenting RadioSED, a Bayesian inference framework for constructing, modelling and classifying radio spectral energy distributions from publicly-available surveys. We focus here on the application of our framework… read more here.

recommendations! Published in 2025 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/staf1698

Abstract: Radio synchrotron emission originates from both massive star formation and black hole accretion, two processes that drive galaxy evolution. Efficient classification of sources dominated by either process is therefore essential for fully exploiting deep, wide-field… read more here.

DOI: 10.1093/mnras/staf2121

Abstract: We present high-angular-resolution ($\sim 0\rlap{.}^{\prime \prime }1$) VLA Ku-band (12–18 GHz) observations of two explosive molecular outflows (EMOs), DR 21 and G5.89, in a search for runaway stars related to these explosive events. In DR 21, we identified… read more here.

DOI: 10.1093/mnras/stx1536

Abstract: Infrared-Faint Radio Sources (IFRSs) are an unusual class of objects that are relatively bright at radio wavelengths but have faint or undetected infrared counterparts even in deep surveys. We identify and investigate the nature of… read more here.
