The Aperture Array Verification Systems (AAVSs) are full-size SKA-low prototype stations located at the Inyarrimanha Ilgari Bundara, also known as the CSIRO Murchison Radio-astronomy Observatory, site. Each of them is composed of 256 SKALA dual-polarization log-periodic antennas positioned within a circular area of $\sim$40 m in diameter. These stations are designed to assess the SKA-low...
In this talk, we will show the status of a C-band Phased Array Feed (PAF) we are developing as part of the SKA Advanced Instrumentation Program (AIP). We are designing a PAF in the frequency range of 4-8 GHz for the primary focus of the Sardinia Radio Telescope (SRT) in order to test all the different technologies needed in the design and construction of a special radio astronomical receiver...
In these talk I will review the successful story of LOFAR, covering a decade of important scientific results obtained with low-frequency radio observations with a particular focus on radio surveys. I will then introduce the LOFAR 2.0 upgrade and the expected improvement in terms of data quality and scientific outcome. The upgrade is aimed at leverage the existing hardware, software and...
