An overview of my outreach/PR images that have been used for (popsci) publications, news articles or the likes.
LOFAR meets Euclid
A combination of LOFAR's view of the Perseus cluster in pink and that of the recently launched Euclid satellite as the background.
Virgo A
Virgo A, or M87, as seen by LOFAR at a frequency of 144 MHz. The radio emission is shown in pink, x-ray emission in blue and visible light as the background.
Perseus
LOFAR's international baseline view of the central galaxy in the Perseus cluster, at a frequency of 144 MHz. X-ray light is shown in blue and the background shows visible light as seen by the Hubble Space Telescope.
Abell 2255
LOFAR's view of the galaxy cluster Abell 2255 at frequencies of 60 (purple) and 144 MHz (pink). Shown in blue is the x-ray emission. The background shows the cluster in visible light.
Abell 2029
LOFAR's international baseline view of the central galaxy in the Abell 2029 cluster at a frequency of 144 MHz.
Abell 339 and 401
LOFAR's 144 MHz view of the merging galaxy cluster pair Abell 339 and Abell 401, with x-rays in blue and visible light as the background.
Abell 2250
LOFAR's view of the central galaxy in the Abell 2250 cluster at a frequency of 144 MHz.
M51
The Whirlpool galaxy, or M51, as seen by LOFAR at a frequency of 144 MHz in red and visible light as seen by HST on the background.
Abell 2256
LOFAR's view of the galaxy cluster Abell 2256 at a frequency of 144 MHz in pink. Shown in blue is the x-ray emission. The background is a near-infrared image from unWISE.
