Hubble sees spiral galaxy that has a radio jet

    #OOTD Most relativistic jets are found in ellipticals, but there are a few found in spirals. This galaxy is outside of the SDSS dr12 footprint.

    Hubble image of spiral galaxy z=0.067 . This is too far away to see a jet in visible light, so we see nothing.

    Despite its unassuming appearance, the edge-on spiral galaxy captured
    in the left half of this NASA/ESA Hubble Space Telescope image is
    actually quite remarkable.

    Located about one billion light-years away in the constellation of
    Eridanus, this striking galaxy — known as LO95 0313-192 — has a spiral
    shape similar to that of the Milky Way. It has a large central bulge,
    and arms speckled with brightly glowing gas mottled by thick lanes of
    dark dust. Its companion, sitting in the right of the frame, is known
    rather unpoetically as [LOY2001] J031549.8-190623.

    Jets, outbursts of superheated gas moving at close to the speed of
    light, have long been associated with the cores of giant elliptical
    galaxies, and galaxies in the process of merging. However, in an
    unexpected discovery, astronomers found LO95 0313-192, even though it
    is a spiral galaxy, to have intense radio jets spewing out from its
    center. The galaxy appears to have two more regions that are also
    strongly emitting in the radio part of the spectrum, making it even
    rarer still.

    The discovery of these giant jets in 2003 — not visible in this image,
    but indicated in this earlier Hubble composite — has been followed by
    the unearthing of a further three spiral galaxies containing
    radio-emitting jets in recent years. This growing class of unusual
    spirals continues to raise significant questions about how jets are
    produced within galaxies, and how they are thrown out into the cosmos.

    known to be producing a giant radio-emitting jet. This close-up of
    the Hubble telescope image has a red overlay from a higher-resolution
