1. Lambda and Vacuum Energy
Analze the relationship between Lambda (on one side of Einstein's equation) and vacuum energy (on the other side), including the implied equation of state and how it evolves with time.
2. Growth of Clustering
Describe how clustering of mass and, therefore, galaxies grows. How could observations of galaxy clustering at different redshift be combined to constrain cosmological parameters?
2. How much mass would a black hole contain if it has an event horizon equal in size to an average sized
tennis ball? Express your first answer, using scientific (powers of ten) notation, in kg and also
express the same answer in "Earth masses."
answer: Mo =
kg =
× MẸ
High Mass Stars
Problem 4. Black Holes
The Schwarzschild radius determines the event horizon of a black hole. Construct the equation defining this radius using the fact that the escape velocity at this radius is c (the speed of light). Use M for the black hole mass and RS for the Schwarzchild radius. (Do not simply write down the equation, show and explain the logical steps of your construction and algebra)

- Which of the following most correctly explains why we have not yet observed any white dwarfs derived from M stars: Group of answer choices Most M stars end up as neutron stars or black holes. The lifetime of M stars is longer than the age of the universe. Most M stars are located near the edge of the universe, beyond the visible horizon. Most M stars are members of a binary system, and the white dwarf would be obscured by the glare of the more massive companion. White dwarfs are too dim to be observed with currently available techniques.arrow_forwardMatch each characteristic below to the appropriate stellar end state. (Select W-White dwarf, N-Neutron star, B-Black hole. If the first is W and the rest N, enter WNNNNNNN). A) Size defined by its Schwarzschild radius. B) Typically about the size of Earth. C) Usually has a very strong magnetic field. D) In a binary system it can explode as a supernova. E) Supported by electron degeneracy pressure. F) Sometimes appears as a pulsar. G) Viewed from afar, time stops at its event horizon. H) Has a mass no greater than 1.4 solar-masses.arrow_forward7. Let's characterize a typical neutron star.

- Which statement concerning black hole masses and Schwarzschild radii is not true? A. Even an object as small as you could become a black hole if there were some way to compress you to a size smaller than your Schwarzschild radius. B. The more massive the black hole, the larger the Schwarzschild radius. C. For black holes produced in massive star supernovae, Schwarzschild radii are typically a few to a few tens of kilometers. D. In a binary system with a black hole, the Schwarzschild radius depends on the distance from the black hole to the companion star.arrow_forwardQuestion A7 State three pieces of evidence that support the idea that the Universe began in a hot Big Bang, and explain how each piece of evidence supports the hot Big Bang model.

How did Edwin Hubble measure the distance to the Andromeda Galaxy? He deduced it from its redshift. He measured its parallax. He used Cepheid variables in the Andromeda Galaxy. He used white dwarf supernovae in the Andromeda Galaxy.arrow_forwardPlease no hand writing solutionarrow_forwardUsing MBH = 6.6 × 10 Mo, calculate the below. a. Find radius of the Schwarzschild sphere (Schwarzschild radius Rs). You can calculated from the appropriate formula or just use the fact that for an object of 1 solar mass Rs = 3 km. b. Express Rs in km, in AU, in parsecs. c. Using the distance to M87 and your result above, find angular radius of the SMBH (Schwarzschild radius). Express it in arcseconds (") and micro- arcseconds (pas) d. Take the radius of Pluto's orbit equal to 40 AU and find its angular size (in micro-arcseconds, pas) at the distance of M87.arrow_forward
