The largest near-infrared image of galaxies ever taken by the Hubble Space Telescope has offered a playground for astronomers who’re searching for out potential targets for the James Webb Space Telescope.
The image is the results of a mission known as 3D-DASH and was captured by the Hubble Space Telescope‘s Wide Field Camera 3 (WFC3), with extra archive knowledge from Hubble’s Advanced Camera for Surveys. It spans 1.35 sq. levels of the sky, equal to about six full moons, and accommodates 1000’s of galaxies. The goal is to determine the galaxies worthy of additional examine by the James Webb Space Telescope and different telescopes sooner or later.
“I am curious about giant galaxies, which are the most massive ones in the universe formed by the mergers of other galaxies,” stated Lamiya Mowla, an astronomer on the Dunlap Institute for Astronomy and Astrophysics on the University of Toronto and chief of the brand new analysis, stated in a assertion. “How did their structures grow, and what drove the changes in their form? It was difficult to study these extremely rare events using existing images, which is what motivated the design of this large survey.”

Ordinarily, it will have taken Hubble 2,000 hours’ price of observations to construct an image this huge, however Mowla’s staff used a brand new approach known as Drift and Shift (DASH), which takes a number of photographs and stitches them collectively, assembling particular person photographs eight instances bigger than WFC3’s typical area of view (0.04 x 0.04 levels). Furthermore, relatively than taking one image each time it orbits Earth, Hubble might take eight photographs utilizing the DASH approach. With a complete of 1,256 particular person WFC3 photographs, it took simply 250 hours of observing time to finish the whole mosaic.
Most of the galaxies within the image are seen as smudges of infrared gentle. The most distant ones are seen as they existed about 10 billion years in the past, and the sunshine of good star-forming areas inside them have been redshifted by the enlargement of the universe into near-infrared wavelengths. You can see these galaxies in additional element in a web-based interactive model of the image from the 3D-Dash image explorer.
Unlike Hubble, Webb will have the ability to scrutinize these galaxies in better element, due to the elevated light-gathering energy of the newer telescope’s 6.5-meter (21.3 ft) mirror. With Webb’s first science-quality photographs set to be launched July 12, the publication of the 3D-DASH knowledge is well timed certainly.
For bigger survey photographs, astronomers should await the European Space Agency’s Euclid mission and NASA’s Nancy Grace Roman Space Telescope, which may have better fields of view (0.79 x 1.16 levels and 0.8 x 0.4 levels, respectively) than Hubble and Webb and are set to be launched in 2023 and 2027, respectively.
The analysis has been accepted for publication in The Astrophysical Journal, and a preprint model is obtainable by way of the arXiv database.
