The galaxy lies at the centre of the massive and merging Norma galaxy cluster. The MeerKAT continuum images (rms ∼0.02 mJy beam<SUP>-1</SUP> at ∼10″ resolution) reveal new features that have never been seen in a radio galaxy before: collimated synchrotron threads of yet unknown origin, which link the extended and bent radio lobes of ESO 137-006. The most prominent of these threads stretches in projection for about 80 kpc and is about 1 kpc in width. The radio spectrum of the threads is steep, with a spectral index of up to α ≃ 2 between 1000 and 1400 MHz.STAMPAenArticle10.1051/0004-6361/2020378002-s2.0-85083165954http://arxiv.org/abs/2004.03203v2https://www.aanda.org/articles/aa/full_html/2020/04/aa37800-20/aa37800-20.html2020A&A...636L...1RFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
