Empirical astronomy/Quiz

The three images on the right record emission events for AT2018cow. The first shows the galaxy Z 137-068. The second down on the right has two markers ending close to the fuzzy bright source AT2018cow. The third down on the right is a sequence of dated images.

"Astronomers using ground-based observatories caught the progression of a cosmic event nicknamed "the Cow," as seen in these three images. Left: The Sloan Digital Sky Survey in New Mexico observed the host galaxy Z 137-068 in 2003, with the Cow nowhere in sight. (The green circle indicates the location where the Cow eventually appeared). Center: The Liverpool Telescope in Spain's Canary Islands saw the Cow very close to the event's peak brightness on June 20, 2018, when it was much brighter than the host galaxy. Right: The William Herschel Telescope, also in the Canary Islands, took a high-resolution image of the Cow nearly a month after it reached peak brightness, as it faded and the host galaxy came back into view."[1]

Empirical astronomy is a lecture about an approach to understanding astronomical phenomena. A portion of it is a mini-lecture empirical radiation astronomy for a quiz-section as part of the radiation astronomy course on the principles of radiation astronomy.

You are free to take this quiz based on empirical astronomy at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the {{radiation astronomy resources}} template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

Quiz

edit

  

1 Yes or No, A list or catalog of the specific principles incorporated into the development of the various radiation astronomies may be helpful to students and researchers alike.

Yes
No

2 True or False, It has recently been suggested by Cane et al. 2002 that a class of type III solar radio bursts, called type III-l, is reliably associated with intense solar energetic particle (SEP) events.

TRUE
FALSE

3 Yes or No, Arguably, the first principle of radiation astronomy is that there is a sky and it is not impervious.

Yes
No

4 True or False, An antiproton is a proton moving backward in time.

TRUE
FALSE

5 Yes or No, It may be an axiom that "there is a sky". But, it is probably a postulate that the sky "is not impervious."

Yes
No

6 As an analysis method NRA may be associated with which phenomena?

a concentration vs. depth distribution
charged particles in large clouds
target elements may undergo a nuclear reaction
projectile stopping power is unknown
proton elastic scattering
a nuclear method in materials science

7 Yes or No, Another early principle may be that outer space exists and it is not a perfect vacuum.

Yes
No

8 Yes or No, It could be stated that space is only a manifestation of the ubiquity of electromagnetic radiation.

Yes
No

9 Yes or No, "Radiation can be used as an approach to present astronomical observations and theory." is an empiricism.

Yes
No

10 True or False, The only theory so far to describe how to produce solar flares is empirical.

TRUE
FALSE
