Two McMaster astronomers have used latest deep imaging knowledge from the James Webb Area Telescope to look 3.5 billion years into the previous to review a distant big cluster of galaxies.

Marta Reina-Campos, a postdoctoral fellow and Canadian Institute for Theoretical Astrophysics Nationwide Fellow, and William Harris, an emeritus professor, have collaborated on a paper that was published in Month-to-month Notices of the Royal Astronomical Society.

The galaxy cluster, referred to as Pandora’s Cluster and infrequently referred to by its catalog identify of Abell 2744, accommodates hundreds of galaxies of all sizes.

Reina-Campos and Harris targeted their work particularly on the outdated, compact clusters of stars referred to as globular clusters which can be present in these galaxies.

Reina-Campos, a theoretician, builds superior laptop simulations of galaxies through which the evolution of their globular clusters might be adopted from their very starting to the current day.

Harris is an observational astronomer who works on measuring the real-world properties of globular clusters in giant galaxies like these in Abell 2744.

“Up till now, we have been restricted to measuring the properties of those star clusters simply in galaxies within the close by universe,” says Harris. “That is like attempting to infer an individual’s historical past by solely working from a present-day photograph of them. What about all that got here earlier than? The James Webb Area Telescope has opened up an enormous new vary of area and time for exploration.”

Abell 2744 is so distant that the sunshine we see right this moment was emitted 3.5 billion years in the past—in regards to the time that life first originated on Earth.

“For the primary time, we are able to see instantly what the options of the star clusters have been like that way back,” says Reina-Campos. “This lets us fill in additional of their previous story and provides solely new checks for what we predict from principle. It’ll additionally assist us perceive extra in regards to the histories of the galaxies themselves.”

The so-called “lookback time” for Abell 2744 corresponds to seeing issues as they have been 1 / 4 of the best way again to the Huge Bang and the very starting of the universe.

Reina-Campos and Harris view their work as the primary stage in a brand new path. “The pictures that JWST is producing are unimaginable—we have by no means seen something like this earlier than. It’ll be one of many premier devices in the whole historical past of science,” says Harris.
