Description:
We have imaged M87 using RGB broadband filters. To reveal faint details by this bright galaxy, we subtracted a realistic model of M87. After subtraction, candidates, some non-stellar emission features became evident in all wavelengths, with the brightest appearing in the red filter window (590 nm to 700 nm). These structures, are not artifacts generated by the galaxy subtraction process but are real features. Those near the M87 core have been previously imaged by the Hubble Space Telescope in a narrower field of view. These features could potentially be structures related to the counterjet, such as counterjet-generated shockfront. To the best of our knowledge this is the first wide field, galaxy-subtracted broadband RGB image of M87. Publication is pending.
