What do we know about the most serious objects of the universe? The new catalog represents heavy gaps – science
The newly published list in the Scientific Journal Monthly Notices of the Royal Astronomical Society, It depends on the observations of the territorial telescope of fermi rays And recognizes Nearly 2,800 ray roots gamma 10 giga electrons-volt (GEV), including 62 so far. In a statement, the result represents an increase of about 80% compared to the last catalog.
Gamma ray extragalactic roots are not very common And right now knows 7,200 throughout the universe. Bruno Arsioli describes most of these resources BlazaresIe. Specific types of active galaxies nuclei, “with a tremendous and high -contained radiation peaks”.
Estes Blazares “Will Electrons-Volt (TEV) has the main population of the extragacactic sourcesTherefore, the priority goals for the future observatory of the Cherenkov Telescope Network, ”the researcher said.
According to Bruno Arioli, the team demonstrated “an extensive review of literature on red deviations”, which found it “Approximately 72% of the roots in the 1 CG catalog still have unfair expectations, or none for their distance”.
This is Lack of information limits knowledge to the highest power photons about the transparency of the universeIt calls out to question how much it is possible to observe extreme resources in the universe, explaining AI.
“This spacing in the current knowledge represents a challenge to the whole society of the study of the most power phenomenon of study”.
But, Why is it important to understand the distance from these cosmic resources? When the gamma rays travel in the universe, they interact with the “Cosmic Fog of Photons” with the Extrogacactic Backlight.
According to AI, the interaction increases the radiation of very high energy from distant objects, which leaves a observable mark in its spectrum. Therefore, the more blazer, this effect is greater. Knowing your distance The density of extragalactic background light at different times of the universe is required to more accurately measure.
The attenuation of Race Race defines a limit to the greater distance of detecting very high energy photons, also known as the cosmic horizon of gamma rays.
Makes the process Ray Blanks Gamma is a kind of “probe” to measure the density and evolution of the Extragacactic backlight throughout the cosmic history.
