A group of astronomers from all over the world, including Raman Research Institute (RRI) in Bengaluru, has seen the lightest blazar suu called PG 1553 + 113 and said the analysis would open the way to understand the process of galaxy merge in the early universe.
Researchers from RRI, along with collaborators from all over the world, capturing this flare using 1.3 million JC Bhattacharya Telescope (JCBT), Cavalur, India.
Astronomers then studied for 76 nights in stretching Blazar using nine different telescopes throughout the world.
Blazar is a nucleus of the active galaxy (Agn) – it is a concise area at the galaxy center.
Flare in Blazar is a flash of sudden brightness, just as we know about solar flares.
PG 1553 + 113, which is the main candidate for binary supermassive black hole systems, new – finally the scientists are tickling because of gamma ray emissions that are repeatedly quasi, astronomers said.
RRI is the Autonomy Institute of the Department of Science and Technology (DST).
DST, while showing that the galaxy often joins throughout the cosmic time, saying that every time two Galaxies of the Harbor, a supermassive blackhole (SMBH) in their centers, the formation of binary SMBH is inevitable.
“SMBHS, it cannot be spatial with the current technique.
Therefore, to look for them, scientists must rely on indirect methods.
One of the indirect search strategies is based on detection of periodicity in the source.
Some candidates recently displayed variability The quasi-periodic light curve has emerged from a large sky survey and a long-term monitoring program.
PG 1553 + 113 is one of them entering the explosion and produces very high energy emissions, “DST said.
This research has been published in the journal ‘Astronomy and Astrophysics’.
Astronomers say in the paper: “We analyzed the light curve using various statistical tests, cross correlation fittings and techniques, and methods for search for periodicity.
We check the color magnitude diagram before and after the corresponding light curve is corrected for long-term variations.” The researchers studied Multiband flux and blazar spectral variability in diverse timespales, said DST, and added that they expect periodicity, radius, size of emissions, magnetic field strength, and electron energy for blazar.
“In addition, after recording flares, they have found that the accelerated particles cool with synchrotron radiation (known as synchrotron cooling) and are the dominant emission mechanism.
These findings can help explore the nature of binary black holes from PG 1553 + 113 can facilitate understanding The galaxy merger process in the early universe, “said DST.
This adds that this analysis also provides interesting targets for multi-messenger observations such as light, neutrinos, and gravitational waves that help us in studying the cosmos.
