Logical inconsistency[edit]

This article contradicts itself by claiming that two different objects were the first microquasar to be discovered.

Towards the end of the first paragraph: The first microquasar SS 433, was discovered in 1979.

The third paragraph: Felix Mirabel, and Luis Rodriguez were awarded the Bruno Rossi Prize of the American Astronomical Society in 1997 for their discovery of the first microquasar, GRS 1915+105.

Which was discovered first, SS 433 or GRS 1915+105? This article is far from clear.PhysicsSean (talk) 13:00, 27 August 2017 (UTC)[reply]

After doing some research I've found that SS 433 was indeed the first microquasar to be discovered. F Mirabel and L Rodriguez were awarded the Bruno Rossi Prize in part for their discovery and subsequent discussion of the so-called superluminal emissions from sources such as GRS 1915+105.

I will update the article now to reflect this. I'll include the reputable sources through which I attained this information.PhysicsSean (talk) 13:17, 27 August 2017 (UTC)[reply]

Accretion disk size[edit]

The article mentions the average size of a quasar accretion disk to be on the order of a billion square km. However, quick searches suggest that quasar accretion disks are much larger than this - on the order of light days in diameter (50+ billion km). E.g. https://academic.oup.com/pasj/article/70/5/97/5103885 https://iopscience.iop.org/article/10.3847/1538-4357/aac9bb https://www.aanda.org/articles/aa/pdf/2007/05/aa6283-06.pdf

The milky way is reported to have an accretion disk 25 times larger than the solar system, although this may be using different definitions on the extent of the disk https://www.realclearscience.com/quick_and_clear_science/2019/06/06/the_milky_ways_supermassive_black_hole_has_an_accretion_disk_thats_25x_larger_than_the_solar_system.html
