A new radio image of the Miracat telescope at the South African Radio Astronomy Observatory in Cape Town, South Africa, presents a detailed image of the early Universe and contains thousands of young star-forming galaxies.
This composite image shows thousands of star-forming galaxies in light radio and the MiraCat radio telescope array in Carlo’s South African half century. The brightest points are the radio galaxies fed by luminous black holes.
Countless weaknesses are distant star-forming galaxies like our Milky Way, which are very deadly, have not yet been detected. Because radio waves travel at the speed of light, this image is a time machine that shows the history of the star’s formation of the universe.
“To create this image, we selected an area in the southern sky that does not have strong radio sources whose brightness can blind a sensitive observation,” said Dr., an astronomer at the South African Astronomy Observatory. Tom Mauch said.
Dr. Mauch and his team inspected the area for a total of 130 hours using 64 Miracat dishes.
A researcher at the National Radio Astronomy Observatory, Drs. James Condon said: “Because radio waves travel at the speed of light, this image is a time machine formed over billions of years in these distant galaxies.”
“Because only short-lived stars that are less than 30 million years old send radio waves, we know that the image is not contaminated by old stars. So, the radio light we see in each galaxy is at that moment.” . It is proportional to its star formation rate. “
“These first results indicate that the rate of star formation around the cosmic afternoon was originally higher than originally expected,” said Dr. Alison Matthews, a graduate student at the University of Virginia and the National Radio Astronomy Observatory.
“The previous images could only detect the tip of the iceberg, rare and luminous galaxies that produced only a small fraction of the stars in the universe. Now what we see is the complete image: these weak points are galaxies that form the majority of the stars In the universe. “
“Only in recent years has technology evolved to the point that we can build spectacular telescopes like MiraKet and have the computing power to create images like this and get a real understanding of how the universe came about.” It’s “Dr. William Cotton said, astronomer at the National Radio Astronomy Observatory.
“Next-generation devices, square kilometer assemblies and very large next-generation assemblies should be even more spectacular.”
The new image of Mircat is described in an article that will be published in the Astrophysical Journal.
