Read the questions slowly and answer with precise and long details about each of the questions. Answer correctly and follow my guidelines for a long and wonderful review after results. Your target/main observable galaxy is the whirlpool galaxy. Target: Whirlpool Galaxy Object Type: Galaxy Distance: 37 million light-years Constellation: Canes VenaticiDO NOT COPY AND PASTE OTHER WORK OR THINGS FROM THE INTERNET, use your own words.
In 500 words, compare and contrast the specific object to at least 2 other objects in its sourceclass (eg. if it's an isolated star, to different types of isolated stars). Explain both observational andphysical differences, as well as what the comparison teaches us about the source class in general.

Briefly explain the evolution/change of star formation rate over the history of the universe (i.e explain the sketch in 2).arrow_forwardThe Tully-Fischer method relies on being able to relate the mass of a galaxy to its rotation velocity. Stars in the outer-most regions of the Milky Way galaxy, located at a distance of 50 kpc from the galactic centre, are observed to orbit at a speed vrot determine the mass in the Milky Way that lies interior to 50 kpc.

- Astronomers frequently say that "there are more stars in the universe than there are grains of sand on all the beaches on the earth". Given that a typical grain of sand is about 0.5 – 1.0 mm in diameter, estimate the number of grains of sand on all the earth's beaches. The diameter of the Earth is 12,742 km. a) About 1011 b) About 1016 c) About 1021. 6. Assume that a typical galaxy contains about 200 billion stars and that there are more than 150 billion galaxies in the known universe. Estimate the total number of stars in the universe. b) About 1022 a) About 1010 c) About 1016. 7. Compare the values of the number of grains of sand in all earth's beaches (from problem 5) with the number of stars in the universe (from problem 6) – which is greater? a) Number of sand grains b) number of stars c) they are about the same.arrow_forwardEach point on the above diagram shows the line-of-sight recession velocity versus distance for a number of distant galaxies. Describe how the recession velocities of galaxies are measured by astronomers.

A galaxy cluster has a galaxy behind it whose image we see as being smeared out and curved, with an angular radius of curvature on the sky of θE. The background galaxy is at redshift zgal and the cluster is at zclust. What is the mass of the cluster in solar masses? Give your response in scientific notation with one decimal place. (The Hubble constant is of course 70 km/s/Mpc, and you can assume the Hubble law for these low redshifts). Values: zgal = 0.11 zclust = 0.07 θE = 117.4 arcsecondsarrow_forward
- Assume that the Milky Way has a central bulge of uniform density with a radius R. Also assumethat the gravitational force due to the flat portion of the galaxy can be neglected. 1.
