Quasars Can Trigger Tsunamis That Tear Across Galaxies And Snuff Out Star Formation

Quasars emit potent radiation at the core of many galaxies, affecting star formation. Quasar outflows are powerful enough to prevent star formation by blasting away necessary matter. These outflows, known as quasar winds, expel hundreds of solar masses annually. Quasars remain in this violent state for billions of years before evolving into conventional black holes. The research suggests that quasars at the core of elliptical galaxies may explain why the universe lacks larger galaxies and more stars.

What is the primary effect of quasar outflows on galaxies?

• They stabilize existing stars.

• They create new galaxies.

• They prevent star formation.

• They enhance star formation.

How do quasar outflows affect interstellar space?

• They generate intense light and heat.

• They create new stars.

• They reduce radiation levels.

• They cool down the space.

What happens to quasars after billions of years?

• They transform into conventional black holes.

• They turn into new galaxies.

• They disappear completely.

• They become more violent.

What scientific puzzle is associated with quasars?

• How quasars form.

• Why the universe lacks larger galaxies and more stars.

• Why quasars are so bright.

• Why quasars are only found in elliptical galaxies.

What role might quasars play in the structure of elliptical galaxies?

• They might be responsible for their elliptical shape.

• They might contribute to the lack of star formation.

• They might cause the galaxies to spin faster.

• They might increase the number of stars.
