A Close-up View of NGC 4151
This image of NGC 4151 shows a close-up of the central region of the
galaxy in an inset. The dimensions of the inset are only 2,000 light years
across. Here, the Chandra X-ray data from the larger image are shown in
blue, and we add in radio data from the VLA (purple) and HST data
(yellow) showing oxygen emission. The linear structures show clear evidence for
an earlier outburst from a supermassive black hole at the center of the
galaxy.

X-ray, Optical & Radio Images of NGC 4151
These images feature the central region of the spiral galaxy NGC 4151.
In the pupil of the "eye," X-rays (blue) from Chandra are combined
with optical data (yellow) showing positively charged hydrogen. The
red around the pupil reveals neutral hydrogen detected by radio
observations. A study has shown that the X-ray emission was likely
caused by an outburst powered by the supermassive black hole located
in the white region in the center of the galaxy. Evidence for this
idea comes from the elongation of the X-rays running from the top left
to the bottom right and details of the X-ray spectrum.
