The Magnetic Fields of Spiral Galaxy M77

Can magnetic fields relief narrate us how spiral galaxies obtain and evolve? To search out out, the HAWC+ instrument on NASA’s airborne (747) SOFIA observatory seen nearby spiral galaxy M77. HAWC+ maps magnetism by staring at polarized infrared light emitted by elongated mud grains rotating in alignment with the local magnetic subject. The HAWC+ portray reveals that magnetic fields enact appear to hint the spiral hands in the internal regions of M77, hands that seemingly highlight density waves in the inflowing gas, mud and stars brought about by the gravity of the galaxy’s oval form. The featured portray superposes the HAWC+ portray over diffuse X-ray emission mapped by NASA’s NuSTAR satellite and visible light pictures taken by Hubble and the SDSS. M77 is positioned about 47 million light years away toward the constellation of the Sea Monster (Cetus).
