Bengaluru: scientists investigate how the shape of hello dark matter affects the movement of stars in the star bar (found in the center of several galaxies) has found that flexible events outside the aircraft at the bar explained the shape of the dark circle of light in the galaxy barred.
Dark matter forms a framework where galaxies are formed, evolved, and join.
Shows that outside the bending bar in the banned galaxy (the central bar-shaped structure consisting of the stars) is a rare bar thickening mechanism known as bend, scientists say trillions of galaxies in the universe have various shapes and sizes, specified by their star movements.
“Our Own Galaxy – Milky Way – is a disk galaxy consisting of stars that move in circular orbit around the middle of the disk flat, with a collection of solid stars in the middle called bumps.
This bulge can have a form starting From almost round to flat with the Galaxy disk.
Milky Way has a flat box or peanut-shaped bulge in the middle.
Such bulges are formed due to thickening of the star bar in the galaxy.
One of the interesting and hard thickening mechanisms is bend, where the bar bends from the disk Galaxy, “said scientists.
Stating that many numerical and observational studies have recently shown that hello dark material in the form of balls, students (balls are squashed from the side), or memory (balls squashed from top and bottom) in the form, they say that the effect on stellar kinematics in the bulge And the galaxy bar is not well understood.
In his work led by Ankit Kumar, a PhD student at the Indian Institute of Astrophysics (IIA) and was written by Prof.
Mousumi Das from IIA and Sandeep Kumar Kataria from Shanghai Jiao Tong University, the team investigated the evolution of the dynamics of galaxics using sophisticated numerical simulations in iia.
Iia is an autonomous institution from the Department of Science and Technology (DST).
DST said that the simulation of the team showed that the bar in Halo, this dark allure was undergoing three prominent events (out of the bend of the plane) in eight billion years which made them detected for a longer time.
“…
this is the first time the three-bar bending event has been reported in any research.
Boxy / bean shaped powder, which is formed as a result of the bending bar, stronger in hello dark matter which is disgusted, and the signature bar luCuan is the most Durable in it.
This work has been published in the monthly notification of peer-reviewed journals from the Royal Astronomy community, “DST added.
The researchers concluded that the scarcity of the determination was observed along with several bending events in the Halo simulation described indicating that the form of hello dark matter in most of the banned galaxies could be (balls were squashed from top and bottom) or round.
“We have studied the influence of Halo non-rounded dark matter in the form of disk galaxies by producing realistic artificial galaxies and developing them in time using supercomputer facilities available in IIA, Bengaluru,” said Ankit Kumar, the main author, the main author, lead author of the paper.
“In our universe, detection of the ongoing bending event is very rare.
For our knowledge, there are only eight galaxies in observations that are currently experiencing bend.
Our studies show that most galaxies that are prohibited may have a circle of light passing or round than hello Premanal, “added the author.
They explained that every bending event thickens the bar further.
During the first bend, the deepest area in the bar was getting thicker, while in the next bending event, the outside bar area was getting thicker.
