Researchers at the University of Kansas (KU) have recently begun research aimed at better understanding the mechanisms involved in the dynamics of galaxy clusters traveling through the “cosmic web” in different scenarios throughout their life cycles. By cosmic network we mean a large-scale structure consists mainly of gas filaments, dark dust and dark matter interspersed with enormous voids.

The project, coordinated by physics and astronomy professor Gregory Rudnick, received a $375,000 grant from the government agency National Science Foundation (NSF). The aim is to examine the subject. “Gas content and star formation characteristics of galaxies” A KU version says that these are modified based on the way they move through the cosmos.

The idea is to recreate the cosmic web in a computer simulation and analyze the gas content and star-forming properties of galaxies moving within the network.

How will the cosmic network of the universe be simulated?

This effort will use images of approximately 14,000 galaxies from the DESI Legacy Survey conducted by NASA’s Wide Field Infrared Survey Explorer (WISE) and Galaxy Evolution Explorer (GALEX) space telescopes; The team will collect additional observations with the Planewave CDK700 telescope installed at Siena College’s Breyo Observatory in Loudonville, USA.

I am trying to understand Effect of environmental factors on the transformation of galaxiesThey “are clustered into large clusters of hundreds to thousands of galaxies, as well as smaller groups of tens to hundreds of galaxies,” Rudnick explains in a statement.

These cosmic structures may be clustered or grouped, or may be fixed in isolated and less dense regions of the universe called “fields”. Although previous studies have simulated the cosmic web with clustered and isolated galaxies, they did not take into account the existence of long filamentous structures of gas, dust, and stars connecting the clusters.

The cosmic web of the universe and the roads of Kansas

The Pleiades star cluster connects galaxies with filaments of gas and dust.

In their simulations, the KU team prioritized these filamentous formations where galaxies encounter “the first time they experienced a dense environment before progressing to groups and clusters,” Rudnick explains. It is as if most galaxies enter “urban centers” while others follow “rural routes.”“, without interacting much with your environment.

“While the filaments resemble interstate highways, these less-traveled routes to dense areas are analogous to driving on rural roads in Kansas to reach the city limits,” Rudnick says. Galaxies are located either scattered along the filaments or “like beads on a string.” Most galaxies are in these groups, says the KU professor.

The team’s expectations are about what might occur while the simulation is running. when environmental influences begin to affect galaxiesand how they behave in the filaments and groups in which they are most commonly found.

Galaxies may lose their ability to form new stars

The Carina Nebula is a well-known stellar nursery.

The focus of the study will be on evaluation. How do the internal conditions of these filaments, fields, groups and galaxy clusters change the “baryonic cycle”?It is the process by which the ordinary matter that makes up all visible objects in the universe is recycled and redistributed throughout the galaxy over time.

Rudnick explains that each cosmic neighborhood changes the way gases in and around galaxies behave, and can even affect the shape of the denser molecular gas that is the raw material of stars. This means that disturbances in the baryonic cycle could theoretically increase or inhibit the production of new stars.

“The space between galaxies contains gas. “In fact, most of the atoms in the universe are in this gas, and this gas can accumulate in galaxies,” says Rudnick. As they pass through the gas around them, they can be subjected to pressure that can be momentarily or permanently removed from the galaxies. As a result, he concludes that the stars at the center of the clusters have lost their power to form new stars.
