The event horizon of a black hole marks the boundary where the escape velocity reaches the speed of light. Calculate the Schwarzschild radius for the event horizon of a 2.30 MSun black hole.

_________ km

HINT: A black hole with a mass of 1 MSun has an event horizon at a radius of about 3 km. How can you calculate the radius for other multiples of solar masses?

You observe a star orbiting the massive object at the galactic center at a speed of 1300 km/s in a circular orbit with a radius of 19 light-days. Calculate the mass of the object the star is orbiting. Enter in solar masses. Stars in the outskirts of a globular cluster are about 43 light years from the cluster's center, and orbit at speeds of about 9 km/s. How massive is this cluster? (answer in solar masses) A star in the...

(a) The luminosity of a certain normal galaxy (i.e. one where the supermassive black hole (SMBH) in its heart is inactive) is 4 × 1010 solar luminosity. Suddenly the SMBH in the galaxy becomes active and starts accreting at the Eddington limit, thereby starting to emit at the Eddington luminosity for that SMBH. If during this phase the AGN becomes as luminous as the rest of the galaxy, what needs to be the mass of the SMBH? (b) If this...

Part 1A: Suppose an object is found to emit X-rays that vary in brightness in 10-minute time intervals. What is the maximum size of this region in meters? HINT: Recall the method for placing a limit on the size of an emitting region is just related to distance = velocity x time. Here, for light, velocity = c. Part 1B:Suppose you measure the total mass of this region to be 106 solar masses (i.e. mass= 106 x the mass of...
