Two recent research from the University of Melbourne will help NASA's quest for universes never before seen by humankind.
The reports, reported in The Astrophysical Journal and the Royal Astronomical Society's Monthly Notes, indicate that NASA's James Webb Space Telescope will discover secret galaxies.
According to a story by SciTechDaily, the study said that the James Webb Space Telescope, "the biggest, most efficient and complicated space telescope ever constructed," and often referred to as "Webb," would be unveiled late next year.
The study said calculations led by Madeline Marshall, Science PhD nominee, indicate that it can do what NASA's Hubble Space Telescope can't do-see through the brightness produced by the "quasars" brightest lights in the universe. The report said that black holes, up to a trillion times the Sun's mass, fuel these quasars.
In the article cited, Marshall, who performed her study at the ARC Center of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D), said, "Webb would open up the potential for the first time to observe these very remote host galaxies."
She said the research would help them answer the questions like: 'How can black holes grow so large so quickly?' and 'Is there a relationship between the mass of the galaxy and the mass of the black hole, like we see in the nearby universe?'
It is understood that quasars often exist at the centers of galaxies. However, the study stated, relative to galaxies without quasars, it has been challenging to say what galaxies are like with quasars.
University of Melbourne co-author of ASTRO 3D, Stuart Wyithen said Webb's observations should provide new insights into these extreme systems.
Wyithen mentioned that the data it collects would help us understand how, in just a billion years, a black hole could expand to weigh a billion times as big as our Sun.
The paper said the University of Melbourne team used the Hubble Space Telescope to study these galaxies in conjunction with researchers from the U.S., China, Germany and the Netherlands.
The paper said they also used a state-of-the-art machine simulation named BlueTides. Carnegie Mellon University's Yueying Ni, who operated the BlueTides simulation, said it was planned in the first billion years in the universe's history to research the development and evolution of galaxies and quasars.
Yueying Ni said, "Its large cosmic volume and high spatial resolution make it possible for us to statistically research certain unusual quasar hosts."
What Was Found in The Simulations?
The study said the simulations helped the team to decide what Webb's cameras might see if the observatory examined these distant structures.
The team concluded that it was feasible to differentiate the host galaxy from the quasar, but because of the limited scale of the galaxy in the sky, it would be difficult, the study stated.
The team also observed that the galaxies hosting quasars "tended to be smaller than normal, covering just around 1/30 of the Milky Way's diameter while having about as much mass as our galaxy.
