(ORDO NEWS) — Astrophysicists from the International School for Advanced Study (SISSA) have obtained data for the first time on a distant and mysterious galaxy that is almost invisible to us using the latest research technology.
The authors of this scientific work also described the main properties of such a rare object for the first time. Scientists have studied a mysterious and very distant object from us.
We are talking about a galaxy that formed in the early universe, just two billion years after the Big Bang. In other words, this is one of the oldest galaxies known to science.
Until recently, almost nothing was known about it, since this mysterious galaxy turned out to be invisible – it was literally inaccessible to observation even with the most advanced instruments.
And only within the framework of a new study, astrophysicists managed to obtain the first data on this mysterious object, as well as for the first time to describe its main properties.
The group of scientists managed to obtain the necessary information with the help of surveys carried out using the ALMA interferometer.
It turned out that the invisible is a compact galaxy containing a large amount of interstellar dust.
The instruments helped scientists look into the past and recorded the galaxy at that period of its evolution, when it was still very young.
The researchers were struck by the enormous rate of star formation of this object. Calculations showed that the invisible galaxy at an early stage of its existence formed stars about 1000 times faster than our Milky Way.
“Very distant galaxies are real treasure trove of information about the past and future evolution of our universe,” says first author Marika Giulietti of SISSA.
“However, studying them is very difficult because they are very compact. very faint light from them.
The cause of this obscuration is the massive presence of interstellar dust, which intercepts visible light from young stars and makes it difficult for optical instruments to detect it.
Therefore, the radiation can only be observed by powerful interferometers.”
