The Eddington luminosity gives a limit on the mass accretion rate of the black hole and therefore of the mass of the black hole. L_edd = 13*10^38 M/M_sun [erg s-1]. When I calculate from this I get that the maximum mass is M = 10^(-8)M_sun... which is impossible. Any ideas?

Hi, thanks for the reply @m Thanks for the reply! Yes, I assumed that it was the time in years. Though, I am not sure if we should take the time span to be the whole time difference between mid 1977 to mid 1980. Why should we do this? I am confused about this. Also, are we not supposed to...

See the attached figure. I understand that we look for the apparent transverse velocity v , for example through v = d/t (d - distance, t - time). The distance to the galactic nucleus is known as D. Though I am not sure how to read off the time from this figure.
