IRAS 14348-1447 is one of the most gas-rich examples known of an ultraluminous infrared galaxy, a class of cosmic objects that shine characteristically - and incredibly - brightly in the infrared part of the spectrum," ESA said in a (https://www.
To this end, ByoPiC will perform the first statistically consistent, joint analysis of complementary multiwavelength data: Planck observations tracing hot, ionised baryons via the Sunyaev-Zeldovich effect, optimally combined with optical and near infrared galaxy surveys as tracers of cold baryons.
Harrington explains that in categorizing luminous sources, astronomers call an infrared galaxy "ultra-luminous" when it has a rating of about 1 trillion solar luminosities, and that rises to about 10 trillion solar luminosities at the "hyper-luminous" level.
Dubbed WISE J224607-052635, this extremely luminous infrared galaxy (ELIRC) shines brighter in the infrared than 300 trillion Suns, likely powered by a supermassive black hole at its core that's a thousand times more massive than the one in the center of our Milky Way.
New tidal tails therefore indicate the quick merging, which could be the trigger of starburst activities in Ultra Luminous Infrared Galaxy (ULIRG).
Using a millimeter-wave radio telescope in Granada, Spain, Philip Solomon of the State University of New York at Stony Brook and his colleagues found that the infrared galaxy emits strong radio signals from carbon monoxide - a telltate sign of star formation.
In the center of NGC 6240, the two black holes in the cores will whip up a frenzy of radiation as they careen towards one another head-on, likely transforming the galaxy into a monster known as an ultra-luminous infrared galaxy, thousands of times as bright in infrared as our Milky Way.
