1.Ionized |
The main conclusions are that the strength of doubly ionized oxygen increases going back over time.
|
Coversion of an atom or a substance into an ion typically through the removal of electrons. |
The manner in which molecules are ionized is one of the fascinations that chemistry holds as a subject of study. |
|
2.Evolution |
The cause of the two different evolutions is due to the physical conditions inside star forming galaxies.
|
The gradual development of something from a simple form to something much more complex. |
The theory of evolution was established by Charles Darwin. |
|
3.Galaxies |
One way to study the conditions of gas in star-forming regions of galaxies is to observe the spectral emission lines
|
A system of billions of stars, comprised of gas and dust and gas too hold together by gravitational attraction. |
The study of galaxies has for a long time fascinated many youngminds. |
|
4.Stellar |
What defines eveolutionary parameters of a galaxy is the rate of star formation, stellar mass and gas content.
|
Relating to a astar or stars. |
The stellar structure was used by NASA to replicate the conditions in the planet Jupiter. |
|
5.Spectral |
One way to study the conditions of gas in star-forming regions of galaxies is to observe the spectral emission lines.
|
Shadowy or incorporeal |
A spectral figure darted about in the back scaring all the campers who beheld the sight. |
Reading Notes:
The process involves oxygern and takes place over a period of time.
Double ionized oxygern strength increase over time as we move back while singly ionized oxygern strength increase up to a certain limit when it starts fropping.
Emission lines are very critical as they are used to figure out the manner in which oxygern is ionized whetehr doubly or singly.
The study as a whole encompassed 700 galaxies and included the rate of start formation in the galaxies.
Summary of Article: ___________The article details the manner in which newly formed stars ionize oxygern in the atmosphere and contribute to the manner in which galaxy evolution takes place over time.The study incorporates the measurements of the emission line s going bac to billions of years ago and the concusion formed is the fact that doubly ionized oxygern and ts increases dates back in time while strength of singly ionized increases and decreases after a while._____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
