It is known that active galaxies have small core regions because we can see them in images! These small regions known as uassars emit perful amounts of both radio waves and gamma rays...

Do only spiral galaxies emit bipolar jets?

Consider the giant elliptical galaxy M87, it has a very small, bright nucleus and a visible jet of matter 1800 PC long racing out of its core. Radio observations show that the nucleus must be no mre than a light week in diameter.


What is a galaxy that has a dense core of stars and has spiral arms called?

All galaxies have a dense core of stars. Spiral galaxies, however, have arms that are often visible. There are two kinds of spiral galaxies: barred, where there appears to be a line running from arm to arm through the core, and ordinary, where there is no bar.


Is a seyfert galaxy a spiral galaxy with an active core?

A Seyfert galaxy is a spiral galaxy with an active core.


What are some economics in the core regions?

Economists have identified regions of the world called core regions of economic development. The core regions are North America, Europe and Japan. China is not currently listed because it does not have the model as described below: The core regions have these characteristics; they have economic diversification; * The nations have a high standard of living; * They are leaders in technology;and * Productivity levels are high.


What is a galaxies core name?

As our telescopes improve, we have discovered that there are supermassive black holes in the cores of many, perhaps most galaxies. Scientists have long known that the galaxies did not appear to have enough mass to stay together; since they DO stay together, there has to be mass - a LOT of mass - that we aren't seeing. Since we don't know anything other as a core for a galaxy then, the Core itself must be called "The Black Hole".


What are the advantages of the core-periphery?

Core-periphery structures can promote economic growth and specialization, leading to higher productivity in core regions and increased access to markets for peripheral regions. They can also facilitate the flow of knowledge, technology, and skills between regions, supporting overall development. However, there are risks of unequal development, with core regions often benefiting more than peripheral regions in terms of resources and opportunities.

What kind of galexies are there?

There are generally three types of galaxies: spiral galaxies, elliptical galaxies, and irregular galaxies. Spiral galaxies like the Milky Way have a disk shape with arms of stars spiraling out from a central core. Elliptical galaxies are shaped like ellipses and contain mostly older stars. Irregular galaxies have a less defined shape and tend to have a mix of young and old stars.


What temp is the earth core?

Outer core From 4400'C in the outer regions near the mantle, to around 6100'C in the inner regions near the inner core (7,952 to 11,000oF).Inner core--between 5,000 and 7,000 degrees C (9,000 to 12,630oF).


What does core periphery mean?

Core-periphery refers to a geographic concept where a core region is economically and politically dominant, while the periphery regions are less developed or dependent on the core. This concept implies a hierarchical relationship between different regions based on levels of economic development and power.


What is the type of galaxy that has a nucleus of bright stars with arms that circles around it?

All types of galaxies have a core with a high star density. All galaxies with "arms" are called Spiral Galaxies, of which there are sub-types related to the shape of the arms.
