Classical vs. Cosmological Redshift LAB

For this lab, you’ll use the following lab write-up as a template. Record

your answers to each question and activity this document, and upload

as a .doc or .pdf document to the following module item for grading:

“Classical vs. Cosmological Redshift Lab Submission”

1) Write a paragraph or two summarizing what you learned from the

background information. Include anything you found interesting,

and propose how you think this information would be helpful in

astronomy and astrophysics.

2) Consider the following formula:

Here z is the redshift and the lambdas represent the observed and

emitted wavelengths for the light in consideration. What does a

redshift of zero mean? What does a redshift of one mean? How

many times longer is the observed wavelength than the emitted

wavelength if the redshift is seven?

3) Consider the following link:

https://lco.global/spacebook/distance-and-lookback…

The lookback time tells us how long the light has taken to reach

us. Why is this not equal to the current distance to the galaxy?

In order to calculate the current distance to the galaxy, several

assumptions about the Universe must be made. How fast is the

Universe expanding? Has it always been expanding at this rate?

These are questions beyond the scope of this lab.

4) In astrophysics we assume that there is no preferred spot in the

Universe and that the laws of physics are the same everywhere in

the Universe. As a result, we would expect objects to be moving

randomly throughout space.

Let’s assume that all of the galactic motion in the Universe is

classical in nature. What would we expect to see as far as redshift

and blueshift are concerned? Would this change in any significant

way with distance? Why or why not?

Now assume that all of the galactic motion in the Universe is

cosmological in nature. What would we expect to see as far as

redshift and blueshift are concerned? Would this change in any

significant way with distance? Why or why not?

5) In reality the galactic motion in the Universe is a mixture of the

two. Consider looking at galaxies with several different redshift

values. Consider the following two cases:

a. Classical motion dominates over cosmological motion. The

magnitude of the random velocity is greater than the

magnitude of the recessional velocity. Now what would we

expect to see as far as redshift and blueshift are concerned?

Would this change in any significant way with distance? Why

or why not?

b. Again repeat, but now assume that cosmological motion

dominates over classical motion. The magnitude of the

recessional velocity is greater than the magnitude of the

random velocity.

6) Consider that light was emitted from a galaxy with a wavelength

of 2.50 * 10

-10

meters. What would be the observed wavelength

for the following redshifts?

a. 0.05

b. 0.25

c. 0.60

d. 1.0

e. 2.0

f. 4.0

g. 8.0

7) Assume that visible light is in the range of 400 nanometers to 700

nanometers. Which of the above would result in observations

being made in the visible light spectrum?

8) Write a two paragraph conclusion of what you have done. Include

any results that may have surprised you.

Project Portfolio Risk

/in /by

Project portfolio risk is more than the cumulative risks of the individual projects. While the risk associated with one or two individual projects in the portfolio may be low, collectively they could have a high impact on the portfolio if, for example, both projects are high-priority in support of a major organizational goal. Project portfolio risk management focuses on organizational goals, projects, and resources, which are known as the portfolio triple constraints. Formally and systematically managing the risks in consideration of these constraints is another way for organizations to evaluate the health of the project portfolio and make adjustments to maintain balance.

For this Discussion:

  • 1-Compare project risk management to project portfolio risk management. What are the similarities? What are the differences?
  • 2- What mitigation actions can organizations take to maximize opportunity and reduce threats from risks to a project portfolio? Describe at least two actions.
  • 3- Which of the mitigation actions do you think is most effective? Why?
  • 4- Why is it important for decision makers to understand metrics and measurements?

Data Visualization

/in /by

Select any example of a visualisation or infographic, maybe your own  work or that of others. The task is to undertake a deep, detailed  ‘forensic’ like assessment of the design choices made across each of the  five layers of the chosen visualisation’s anatomy. In each case your  assessment is only concerned with one design layer at a time.

For this task, take a close look at the data representation choices:

  1. Start by identifying all the charts and their types
  2. How  suitable do you think the chart type choice(s) are to display the data?  If they are not, what do you think they should have been?
  3. Are the marks and, especially, the attributes appropriately assigned and accurately portrayed?
  4. Go  through the set of ‘Influencing factors’ from the latter section of the  book’s chapter to help shape your assessment and to possibly inform how  you might tackle this design layer differently
  5. Are there any  data values/statistics presented in table/raw form that maybe could have  benefited from a more visual representation?

Note: Please answer all the questions in detailed in APA format. Also see the link http://book.visualisingdata.com/chapter/6
