New paper leads to a better understanding of radio telescopes

Radio telescopes are very complex instruments. Unlike telescopes using mirrors that measure visible or infra-red light, most modern radio telescopes are made of many antennae, each acting like a pixel. Combining the signals of each of the antennae, like the 64 dishes of the MeerKAT telescope is very complex and adding them into what is …

New group of galaxies discovered by the MIGHTEE team

When the science world decided to embark on the Square Kilometre Array (SKA) project, serendipitous discovery – essentially chance findings – was boldly cited as a scientific goal. The MeerKAT telescope is already proving this bet right, as new, previously unidentified galaxies were discovered by the MIGHTEE project team in a well-studied area in the …

New paper: The Global Magneto-Ionic Medium Survey: A Faraday Depth Survey of the Northern Sky Covering 1280-1750 MHz

The Galactic interstellar medium hosts a significant magnetic field, which can be probed through the synchrotron emission produced from its interaction with relativistic electrons. Linearly polarized synchrotron emission is generated throughout the Galaxy, and at longer wavelengths, modified along nearly every path by Faraday rotation in the intervening magneto-ionic medium. Full characterization of the polarized …
