problem 37: (2% of assignment value)
which of the following observations is a convincing argument for the idea that quasars are located inside galaxies?

please select the best choice from the available options.
○ quasars vary in brightness with time
○ quasars have been discovered in more than one direction in space
○ relatively nearby quasars show \fuzz\ around them with the same spectra and redshift as the quasar
○ quasars appear to be small in angular extent (they look like points)
○ you cant fool me; there is no evidence whatsoever that quasars are connected with galaxies

Explanation:

To determine the convincing argument that quasars are inside galaxies, we analyze each option:

• "Quasars vary in brightness with time" relates to their internal processes, not their location relative to galaxies.
• "Quasars discovered in multiple directions" just shows their distribution in space, not their association with galaxies.
• "Relatively nearby quasars show 'fuzz' (galaxy - like structures) with same spectra/redshift" suggests the fuzz is a galaxy and the quasar is within it (same redshift implies same origin).
• "Quasars look like points" describes their angular size, not their location.
• The last option is incorrect as there is evidence (like the fuzz observation) for quasar - galaxy connections.

Answer:

C. relatively nearby quasars show "fuzz" around them with the same spectra and redshift as the quasar
