Deep Hubble Space Telescope Ultraviolet Imaging of the M87 Jet Eric S. Perlman1, William B. Sparks2, Juan P. Madrid2, Dan Harris3, F. Duccio Macchetto2 +, John Biretta2 1Florida Institute of Technology, 2STScI, 3Harvard-Smithsonian CfA, +ESA ABSTRACT Near-Ultraviolet imaging with HST offers the best possible spatial resolution currently available for optical/UV astronomical imaging. The giant elliptical galaxy M87 hosts one of the most spectacular, best studied and nearest (d=16 Mpc) galactic-scale relativistic (synchrotron emitting plasma) jets. We have extracted from the HST archive all 220 nm images of the jet of M87, taken with the STIS MAMA camera and co-added them to provide the deepest image ever at this wavelength. The combination of highest spatial resolution and long integration time, 42,500 seconds, reveals a wealth of complex structure, knots, filaments and shocks. We compare this image with deep imaging data in other wavebands.
