Exercise 1

Using the data above in Table 1, make a plot of right ascension versus declination on your printed out Milky Way Globular Clusters Distribution Graph (Diagram 1-the top plot). RA is along the x-axis and goes from 0 to 24 hours, Dec is on the y-axis and goes from +90 to 0 to –90 degrees.) Insert the plot into your lab report with your signature and date.

You will type your answers to the below questions in your lab report and then scan/photo your graph(s) and insert them into your lab document. Again, it would be helpful to review the Exploration from Module 1: “Math Primer for Astronomy” (note this contains link for a free online scientific calculator). There are also good math examples in the Appendix of our eText.

Would you describe the distribution of clusters on the plot as random, or is there a pattern (explain your answer)?
Now look at your plot and point in the direction in which you see most of the globular clusters. This is the general direction of the Galactic Center. Estimate the center of the distribution of the globular clusters. Also estimate (no calculation required — just an educated estimate) the accuracy of determining this center. You have now determined the rough center of our Galaxy!

RA = ____________________ ± ________________

Dec = ____________________ ± ________________

Shapely was correct in thinking that the distribution of globular clusters could reveal something about the Galaxy as a whole. He went one step further. He used the locations of the globular clusters to determine the distance to the Galactic Center. His result was surprisingly accurate and differed from the modern value by less than 10%. So, let’s follow in his footsteps.

The next step is to determine the distance to the clusters. Shapely did this by using RR Lyrae stars. These are variable stars, which have a relatively narrow range of luminosities. From the difference between the apparent magnitudes (measured from his photographic plates) and the absolute magnitudes (calculated from the luminosities), he calculated the distances in parsecs to the star (via: m – M = 5log10(d) + 5). So now we have the distances and the directions of the globular clusters and we can determine the 3-dimensional distributions of the globular clusters relative to us.

However, we will use a different coordinate system that is based on galactic latitude and longitude rather than RA and Dec. The plane of the Galaxy is designated as “0 latitude”. Why would we want to do this? RA and Dec is a messy coordinate system that depends on our orientation in space and the earth’s rotation around its axis. The system based on galactic latitude and longitude is therefore simpler. However, it means that we have to transform the measured RA and DEC positions of the globular clusters and galactic latitude and longitude. To simplify things even further, let’s express the galactic latitude and longitude in terms of x, y, and z coordinates. The advantage of this is that x, y, and z have units of parsecs (rather than angles which is the case with galactic latitude and longitude).

So now the z-coordinate tells us how far above or below the galactic plane we are, and the x-coordinate tells us how far away from the origin (in this case from the Galactic Center) we are! The y-coordinate tells us where in the x-y plane (in the Galactic Disk) we would be found. But since we assume that the disk is a round circle (i.e., it is symmetric), we only need to worry about the distance from the center in the disk. Basically, we are only concerned about two quantities: x and z, i.e., how far above and below the Galactic Disk the globular clusters can be found and how far away from the Galactic Center they are.

x, y, z axis disk of Galaxy

Using the data given in Table 1 plot “x” against “z” on your printed copy of the X-Z Plot (Diagram 2). In this graph the x-axis points towards the Galactic Center, the z-axis is perpendicular to that, with positive numbers pointing up, and negative numbers pointing down.

On your X-Z Plot identify the disk, the bulge, and the halo of the Galaxy. Clearly label each component. [Remember that this is a two-dimensional drawing: the y-axis is collapsed into the plane of the Galaxy (i.e., the y-axis has been eliminated); you are only looking at the x-z plane].

Assume that the center of the Galaxy is in the center of the distribution of the globular clusters. Figure out where you could draw a line parallel to the z-axis (the vertical axis) such that equal numbers of clusters fall on each side of the line. So then, the z-coordinate of the center should be set to 0. Using a pen of a different color mark the new scale in your plot. Insert the plot into your lab report with your signature and date.

Type out your answers to the below questions in your report.

Most globular clusters are located in a narrow range above and below the galactic plane. Roughly how many kiloparsecs above and below the galactic place are those globular clusters (i.e., how thick is the disk of the Galaxy in kilo-parsecs)? Estimate the uncertainty in that number.

Thickness of Galactic Disk = ___________ ± ___________ kpc

Measure the distance in kiloparsecs from you to the central point in the distribution of the globular clusters. How many kiloparsecs away is the center? Estimate the uncertainty in that number. (NOTE: this value will also be used for Part 2 of this lab)

Distance to Galactic Center = ___________ ± ___________ kpc

From that plot, what diameter would you infer for the disk of the Galaxy?

Diameter of disk of Galaxy = ___________ ± ___________ kpc

What diameter would you infer for the halo of the Galaxy?

Diameter of Halo of Galaxy = ___________ ± ___________ kpc

Look at your answers in questions 3, 4, 5, 6 and 7. Which of those quantities have the largest uncertainty, which one’s the least? Explain your answer.
How far above or below the Disk of The Galaxy would you place our Solar System?

Distance to Disk of the Galaxy = ___________ ± ___________ kpc

Let’s compare the data on globular clusters to data on novae. The work has been done for you and the distribution of the novae have been plotted on the Milky Way Novae Distribution (Diagram 3). Your task is to understand and interpret this plot. Compare diagrams 3 and 1 — the distribution of globular clusters to the distribution of novae – then sketch the Milky Way onto your printed out Milky Way Globular Clusters Distribution Graph (Diagram 3 – the bottom plot), the plot of the novae.

Determine the position of the Galactic Center from Diagram 3.

RA = ____________________ ± ____________________

Dec = ____________________ ± ____________________

Diagram 3 seems to have an additional “arc” of points for right ascensions ranging from 0 to 12 hours. What is this? Is this some type of illusion, or was that omitted in Diagram 1? Explain your answer.
Compare the distributions of globular clusters and novae. Is the bulge equally big (give the numbers behind your answer)?
Is the disk equally thick (give the numbers behind your answer)?
Would you expect to derive the same overall shape of the Galaxy from both data? Explain your answer.

Part 2: Calculating the Mass of the Milky Way

Orbital Velocity formula

The enclosed equation is the Orbital Velocity Law which allows us to use the orbital speed (v) and radius (r) of an object on a circular orbit around the galaxy to tell us the mass (Mr{“version”:”1.1″,”math”:”<math xmlns=”http://www.w3.org/1998/Math/MathML”><msub><mi>M</mi><mi>r</mi></msub></math>”}) within the orbit of the object. For our calculations the object will be our sun in its orbit through the Milky Way Galaxy.

In this formula v equals the velocity of the Sun in its orbit around the galaxy and G is the value of the gravitational constant. Use the following values for your calculations. Show all calculations with your submitted lab.

r = ____________ kpc (kiloparsecs) (this value is from Part 1, Question #4 of this lab)

v = 250,000 m/s

G = 6.67 x 10-11 m3 / kg s2

For all measured values of this equation to be equal you r value in kiloparsecs (kilo = 103) must be converted into meters since the distance value for the Gravitational Constant, G, is given in meters. Use the following conversion value to convert your r value, in kiloparsecs, to an r value in meters: 3.08 x 1019 m / 1 kpc

Exercise 2

Convert your r value in kiloparsecs to an r value in meters (display your answer in scientific notation)

Now that you’ve converted this distance to meters all terms are alike for the remainder of the calculation & will cancel out leaving your final value in terms of mass (kilograms or kg).

Now, use the Orbital Velocity Formula to calculate the mass of the Milky Way Galaxy (again, show each step of your work displayed in scientific notation)

Your answer for Question #2 is a very large number that no one has the ability to comprehend so let’s try to put it into terms of something we do understand, – our Sun. The Sun has a solar mass that is signified by M (or the Sun’s mass = 1

M. In kilograms 1M equals 2 x 1030 kg.)

Convert the mass of the Milky Way Galaxy calculated in Question #2 into solar masses, or M⊙. (again, show each step of your work displayed in scientific notation)

screenshot of the Milky Way Rotational Velocity Explorer

Use this hyperlink, Milky Way Rotational Velocity to find the actual mass of the Milky Way Galaxy and compare your calculation to the actual mass. (you will need to move the shaded red region down to the diameter of the Sun) This is a screenshot of the Milky Way Rotational Velocity Explorer.

How do the two measurements for mass of the Galaxy compare? Identify any sources that would make your calculation inaccurate.
Calculate your percent error in for calculations with the following formula. (show your work)

(m actual – m calculated / m actual) x 100 = ________

I turned to the service twice, and my papers always were beyond the expectations. To tell the truth, I was ready to find some grammar errors or something like that. However, everything was neat and tidy.

August 5, 2021

My friend recommended Doctor My Essay to me. It is convenient! Now we both turn to the service periodically coz wanna save some time and use it more effectively. I know that while I’m developing my startup, an expert is working on paper. Time management in work!

I write all paper works by myself but have some problems with literacy. Actually, I have enormous problems because English is not my native language. However, with proofreading from Doctor My Essay, I can relax and don’t be ashamed of mistakes.

Argumentative Essay

August 5, 2021

Your ability to write concisely is a finding. The paper has a solid argument. It’s clear that the writer understood central claim about the topic. He also presented original ideas to consider.

I was convinced that paper writing services are the fiction for naive students. But when it came to my research paper that was to be composed in 72 hours, I had no other options. I made the right choice when I ordered it from you!

Business Plan

August 5, 2021

I was also satisfied with the service. Usually, I write everything by myself, but this time ( I have no idea how it happens!) I missed the deadline. My writer was very responsible, wrote the essay quickly, and kept the instructions. Nice to know that such experts exist!

I understand that buying essays is a doubtful thing. You don’t put effort, don’t represent your ideas… However, I don’t perceive Doctor My Essay as a standard service. They don’t sell papers. They share high expertise!

According to my previous experience, this service is really the best. They support the client and have competitive writers. I give them a perfect score!
