TL;DR: The Murchison Widefield Array (MWA) is a new low-frequency, wide field-of-view radio interferometer under development at the MRO in Western Australia.
Accretion and outflow in the Circinus AGN
TL;DR: The first VLBI images of water maser emission in the Circinus Galaxy AGN show both an accretion disk and outflow 0.1 to 1 pc from the central engine as mentioned in this paper.

Mapping the Milky Way and the Local Group
Mark J. Reid,Andreas Brunthaler,Xu Ye,Zheng Xing-wu,Karl M. Menten,Lincoln J. Greenhill,Luca Moscadelli +6 more
TL;DR: In the past decade, the accuracy of Very Long Baseline Inteferometry (VLIB) has improved dramatically as mentioned in this paper, achieving accuracies of ∼ 10 μas for the first time.
Measuring Noise Parameters Using an Open, Short, Load, and λ/8-Length Cable as Source Impedances
TL;DR: In this article , the authors proposed a new method of noise parameter extraction using a singularity-free matrix that is compatible with high-reflection sources. And they showed that open, short, load, and an open cable (OSLC) can be used to extract noise parameters and detail a practical measurement approach.
