A month ago I took part at a local workshop and it changed my view of the high-resolution, high energy Universe! The workshop took place at the Thüringer Landessternwarte in Tautenburg (TLS), where I currently work. Our teachers, Dr Nadia Biava (TLS), Dr Alexander Drabent (TLS) and Dr Etienne Bonnassieux (Uni of Wuerzburg). The topic: processing observations from the LOFAR international radio telescope to create high-resolution images of the sky! The way: sophisticated pipelines that process and clean the data, they combine observations from several telescopes that observe the same target in the sky, and they create a state-of-the-art image for scientists to explore.

I personally use the pipeline to process data of the COSMOS field, a legacy two square degree equatorial field which has been observed with almost every telescope on Earth and in Space, including the fabulous Hubble space telescope and JWST! What I got after 1 month? A high-resolution image of an active galaxy at radio wavelengths at 144MHz, with resolution similar to older observations at 3GHz. This will help us understand things about the radio sources such as formation, lifetime, and interaction to its surrounding environment. The processing is still underway, so stay tuned for more!
