Roman telescope will have 1000 times the speed, 100 times wider view than Hubble


NASA's Nancy Grace Roman Space Telescope will look for tiny primordial black holes that could have formed in the first chaotic moments of the early universe.

“Finding a population of Earth-mass primordial black holes would be an incredible step forward for both astronomy and particle physics because these objects could not have been created by any known physical process,” said postdoctoral researcher William DiRocco of the University of California, Santa Cruz. ” Cruz.

DiRocco, who led the study of how the Romans might reveal them, said, “If we find them, it would shake up the field of theoretical physics.”

Instead of looking for intact early stars, referred to as Population III (Pop III) stars, Roman will search for what is left of them after they wandered too close to the black hole and were destroyed in events that astronomers call tidal disruption events. Or called TDE. , informed of space.com,

Primordial black holes with mass similar to Earth could survive

Scientists believe that when the universe was being born, it may have experienced a brief but intense phase known as inflation when space expanded faster than the speed of light.

Under these special circumstances, regions that were denser than their surroundings would have collapsed to form a low-mass primordial black hole.

Astronomers believe that the smallest black holes may have evaporated before the universe reached its present age, but primordial black holes with masses similar to Earth may have survived.

Findings could have major impact on astronomy

Their discovery in space is expected to have a wide-ranging impact on physics and astronomy.

“This will affect everything from galaxy formation to the dark matter content of the universe to cosmic history,” said Kailash Sahu, an astronomer at the Space Telescope Science Institute in Baltimore who was not involved in the study.

“Confirming their identity will be hard work and require a lot of convincing to astronomers, but it will be worth it.”

Previous observations suggest that there are more Earth-mass objects flowing through the galaxy than models predict.

“There's no way to tell between Earth-mass black holes and rogue planets on a case-by-case basis,” DeRocco said.

Scientists expect that Roman will find 10 times more objects in this mass range than ground-based telescopes. “Roman will be extremely powerful in distinguishing between the two statistically.”

Roman Space Telescope will reveal new information

According to NASA, finding the primordial black hole would reveal new information about the very early universe and strongly suggest that an early period of inflation did indeed occur.

It could also explain a small percentage of the mysterious dark matter that scientists say makes up the bulk of our universe's mass, but have been unable to identify until now.

“This is an exciting example of what some scientists can do with additional data that Roman is already going to get during his planetary exploration,” Sahu said. “And the results are interesting whether or not scientists find evidence that Earth-mass black holes exist. It will strengthen our understanding of the universe in any case.

Roman Space Telescope to launch by May 2027

Managed at NASA's Goddard Space Flight Center in Greenbelt, Maryland, the Nancy Grace Roman Space Telescope is a NASA observatory designed to address essential questions in the areas of dark energy, exoplanets, and infrared astrophysics.

It will have a bird's eye field of view of the universe that will be 100 times wider than the Hubble telescope.

Scheduled to launch by May 2027, the Nancy Grace Roman Space Telescope will unveil the universe in ways never before possible.

Roman will survey the sky 1,000 times faster than Hubble, while maintaining the same sensitivity and infrared resolution. ROMAN will observe billions of cosmic objects to discover how planets, stars and galaxies form and evolve over time.
