cds-question@unistra.fractive-galactic-nucleiradio-galaxiesinfrared-sourcesradio-continuum-emissionh-ii-regionsmagnetic-fieldsWe present the spatially resolved emission of Arp 299 revealed by 150 MHz international baseline Low-Frequency Array (LOFAR) and 1.4, 5.0, and 8.4GHz Very Large Array (VLA) observations. Nowadays, LOFAR allows to compare its resolution with the VLA ones. These will allow us to obtain pixel-by-pixel spectral imdex maps and local radio SEDs. With this information we recover the nature of the ISM around the main structures (either clumpy or continuous), as well as magnetic fields. The 150MHz image also shows structures never seen before, pointing out that these radio-frequencies observations are a perfect tool to detect them.2022A&A...658A...4Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/658/A4CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/658/A2 : LOFAR Long-Baseline Calibrator Survey.
