New red galaxies turn out to be already known blue galaxies

Quasars, a few of the brightest objects within the Universe, are pushed by a supermassive black gap with a mass that may attain greater than a billion instances that of the Solar. These objects are the main focus of a lot analysis, however how they type stays poorly understood. The prevailing idea is that they type in galaxies with clouds of gasoline and mud that obscure the rising quasar till it’s highly effective sufficient to blast away the clouds. If that is true, it ought to be capable to catch the quick timeframe the place a quasar breaks out of its cloud.

As a result of the transition interval is brief, it’s essential to watch numerous pre-quasar candidates and hope to get fortunate sufficient to catch a galaxy simply because the quasar begins to interrupt out. information from JWST, a bunch of extraordinarily pink objects (EROs) had been recognized as doable transitionary quasars. However then researchers on the Subaru Telescope, a Japanese telescope in Hawai`i, observed that regardless that they’re referred to as “pink,” EROs even have a big blue part, much like blue-excess mud obscured galaxies (BluDOGs) present in Massive Information from the Subaru Telescope and described in a report final yr.

Evaluation confirmed that EROs and BluDOGs are seemingly the identical class of objects, however necessary variations additionally exist. One chance is that EROs are in an earlier stage of their evolution than BluDOGs. To find out the true relationship between EROs, BluDOGs, and quasars a bigger pattern of candidates must be collected. The bigger pattern can be studied by the subsequent technology of astronomy devices together with an infrared area telescope undertaking referred to as GREX-PLUS being deliberate in Japan.
