ASKAP Radio Telescope Maps as a survey instrument capable of quickly viewing

ASKAP Radio Telescope Maps of approximately three million galaxies. Astronomers using CSIRO’s Australian Square Kilometer Array Finder (ASKAP – askap radio telescope maps) have mapped around 3,000,000 galaxies in the observable universe. ASKAP conducted its first survey of the entire southern sky with record speed and detail, creating a new atlas of the universe.

It is located at the Murchison Radio Astronomy Observatory (MRO) in Western Australia and is operated by the Commonwealth Scientific and Industrial Research Organization (CSIRO). The ASKAP 36 is a 12m main focus antenna array. Each phased array is equipped with feeders that allow the simultaneous digital formation of 36 dual polarization beams.

CSIRO Executive Director Dr. Larry Marshall said: ASKAP is applying new techniques to science and technology to equip centuries-old questions about the mysteries of the universe. As well as to equip astronomers around the world with new successes. “This is enabled by innovative receivers developed by CSIRO using phase-powered technology.

Which sees ASKAP generating more raw data at a faster rate than all of Australia’s internet traffic.” Using the ASKAP telescope, CSIRO astronomer David McConnell of the Rapid ASKAP Continuum Survey (RACS), ASKAP radio telescope maps and his colleagues viewed 83% of the entire sky. Their result shows that a study of the entire sky can be done in weeks rather than years, opening up new opportunities for discovery.

ASKAP’s advanced

The new data will allow astronomers to perform statistical analyzes of large populations of galaxies, in the same way that social researchers use information from a national census. Dr. McConnell said: This census of the universe will be used by astronomers around the world. To discover how galaxies and their supermassive black holes evolve and interact, starting with the formation of stars. With ASKAP’s advanced receivers.

The RACS team only needed to combine 903 images to create a complete map of the sky, from the tens of thousands of images required for the first radio surveys of the entire sky conducted by the main telescopes of the world. It was pretty low. The 13.5 exabytes of raw data generated by the radio telescope were processed using hardware and software custom built by CSIRO. The final 903 images and supporting information amount to 26 terabytes of data.

Three million galaxies

We hope to find millions of new galaxies in future studies, Dr. McConnell said. The team’s results were published in the publications of the Astronomical Society of Australia. The CSIRO radio telescope mapped three million galaxies in the record-breaking Southern Sky Survey. The dish-shaped antennas point to a sky filled with stars and location markers, which connect to magnified images of objects in space.

ASKAP’s first survey mapped radio-emitting objects such as galaxies, supernova remnants, and the planet. An Australian radio telescope conducted an unprecedented survey of the southern sky, mapping three million galaxies, including nearly a million never before seen, in just two weeks.

Distant galaxies

ASKAP, consisting of 36 satellite dishes, is a radio telescope designed to quickly survey large parts of the sky. The test, the Rapid ASKAP Continuum Survey, was a ‘census’ of the universe that will be used by astronomers to detect the unknown. Most of the millions of stars in the resulting map are distant galaxies.


A radio telescope located about 370 kilometers northeast of Geraldon in Western Australia. And the results considered are a game changer for astronomers. The Rapid ASKAP Continuum Survey (RACS) has created a “Google Map” of the Universe from 903 radio images in 300 hours. In the past, similar surveys took years to complete.

Scientific community

CSIRO astronomer and lead author David McConnell said it is an important milestone for the radio telescope and the scientific community. The fact that it is done quickly is very important. It is a game changer, he said. This means that we can go back and do it again without much effort, and this gives astronomers the opportunity to look for things that have changed.

Most things happen in the same year after year, but some things change dramatically. They often get quite alien: black holes merge or explode stars episodically. The survey was designed to test the telescope’s systems and ensure that it could meet high-throughput processing requirements for future sets of square kilometers.

Galaxies form stars

‘Census of Stars’ – Located within the radio-silent Murchison Radio Astronomy Observatory (MRO), the vast area of ASKAP, created by 36 CSIRO-designed satellite dishes and receivers, provides highly detailed panoramic images of the sky. Lets be taken quickly and it detects a dim light from far away. Six dish-shaped antennas are placed on the red sand between the green bushes, pointing to the blue sky.

Astronomers will use the data to discover how galaxies form stars and interact with each other and with supermassive black holes. While only 15 minutes in the survey were spent looking at each part of the sky, the final images show twice the level of detail compared to the results of the previous survey.

Each of the 903 images consists of 2,000 to 4,000 objects, and the survey covers 83 percent of the sky. Dr. McConnell described the final image as a “census” of the universe, which included exploding stars, pulsars, and the remnants of nearby planets.

Dozen extraterrestrial stars

He said the data would be used by astronomers around the world to uncover the mysteries of the universe. They are already looking for images of stars in our galaxy, which may be active, he said. The sun, our own star, has periodically exploded radio emissions that could interfere with our own terrestrial radio communications. They have found several dozen extraterrestrial stars.

Which have an excessive burst of energy … and looking at them helps us understand what the physics of these types of stars is. ASKAP surveyed the entire visible sky from the Murchison Radio Astronomy Observatory in Western Australia. (Assumption: CSIRO).

The 13.5 exabytes of raw data generated by the telescope were processed and recreated using CSIRO’s custom ASKAPsoft software at the Pavsey Supercomputing Center in Kensington, Western Australia. “It’s great to see all these sources in their strange shapes, even for an astronomer who is used to thinking about how big the universe is.”

Galaxies with new telescopes

Although no extraterrestrial life was detected during the study, occasional stars with unusual radio emission activity were detected. Dr. McConnell said the team is not expected to find any evidence of aliens with binoculars, but nothing has been ruled out. When we see some type of object that changes its radio power, there is the slightest possibility that it is not natural radiation, that it can be produced by some intelligent lifestyle.

CSIRO stated

CSIRO, the National Science Agency, said its new telescope had created “a new atlas of the universe” in record time, showing unprecedented expansion. The study said it mapped a total of three million galaxies, with images revealing twice the level of detail of previous studies. Astronomers hope the images will make new discoveries about the universe.

CSIRO stated that the mapping took only 300 hours, while all previous studies of the sky took years. With publicly available data, scientists around the world “will be able to study everything from star formation to the evolution and interaction of galaxies and their supermassive black holes,” said lead author Dr. David McConnell. said.

Preliminary results were published in the publications of the Astronomical Society of Australia on Tuesday. What is this telescope? The Australian Square Kilometer Array Pathfinder (ASKAP) is a collection of 36 satellite dishes that work together to take a panoramic view of the sky.

CSCRO stated that by combining signals from smaller dishes.

The telescope produces high-resolution images at a fraction of the cost of a much larger dish. Huge amounts of data, generated at a rapid rate, compared to all Australia’s internet traffic, is then sent to the supercomputer processing facility in Perth to create images.

What have you found

Askap conducted its first survey of the sky this year, covering 83% of the sky and covering three million galaxies. Australia started the National Space Agency. The map was stitched using only 903 highly detailed images. Previous studies required tens of thousands to complete an image of the sky.

Astronomers said the depth and scale were exciting because by cataloging millions of galaxies beyond the Milky Way, they could perform scientific analysis. These can help to understand how the universe evolved and is structured.

The Moon will help us teach us about the existence of deep space. The Askap telescope is one of the pioneers of an international project to build the world’s largest radio telescope, the Square Kilometer Array, which will be located in South Africa and Australia.
