Very Long Baseline Interferometry with the SKA Observatory

J. F. Radcliffe, J. Yang, Z. Paragi +129

Very Long Baseline Interferometry (VLBI) is a fundamental technique that combines signals from telescopes separated by thousands of kilometres to obtain some of the highest-resolut…

Cosmic Rulers: Masers as Tools for Probing Structure in the Galaxy and Beyond, from AU to kpc

Kazi L. J. Rygl, Anna Bartkiewicz, Olga Bayandina +9

Maser emission provides an unique window into astronomical sources across vast spatial scales - from tens to hundreds of astronomical units around protostars and evolved stars up t…

An updated model for the Perseus Spiral Arm from Trigonometric Parallax and 3-dimensional kinematic distances of distant massive stars

Lucas J. Hyland, Mark J. Reid, Simon P. Ellingsen +3

We report trigonometric parallaxes and proper motions for three water masers and one methanol maser obtained with the VLBA as part of the BeSSeL Survey. Incorporating these paralla…

Variability of Sagittarius A* at 3 GHz on minute-scale with MeerKAT

K. Kaur, I. Rammala-Zitha, A. Basu +21

The supermassive black hole Sagittarius A* (Sgr A*) exhibits temporal and spectral variability across the electromagnetic spectrum. However, variability at radio frequencies below…

Massive star formation at the Galactic crossroads: Insights from G358.69+0.03 in the Galactic center

A. Cheema, V. S. Veena, K. M. Menten +7

We investigated the high-mass star formation activity in a subregion of the Sagittarius E star-forming complex, centered at (l,b) = (358.69 deg, 0.03 deg), where infrared and radio…

Heavy interstellar scattering toward the near end of the Galactic bar

A. B. Pushkarev, A. Brunthaler, Y. Y. Kovalev +8

We present results of a pilot observational wide-field VLBI campaign on probing scattering properties of the partly ionized interstellar medium towards the Galactic plane sky regio…
