quasars - 2024 ACF Winter - Buzzpoints App

Question

In 2020, a 13-billion-year old one of these objects named Pōniuā‘ena (“PO-nee-wa-EN-uh”) was discovered with a 1.5-billion-solar-mass black hole at its center. For 10 points each:

[10e] Name these very bright active galactic nuclei, whose common name comes from a shortening of “quasi-stellar radio source.”

ANSWER: quasars

[10h] Quasar-host galaxies are often contrasted with these other active galaxies, which have an active nucleus but also a clearly detectable host. These galaxies named for an American astronomer come in Type I and Type II kinds.

ANSWER: Seyfert galaxies

[10m] Twin Quasar 55 was the first observation of this phenomenon, which can lead to the formation of Einstein rings if a source, observer, and intermediate body are all aligned.

ANSWER: gravitational lensing [accept strong gravitational lensing or weak gravitational lensing]
