Sgr A*, the best-sampled of all AGN?

Astrophysics without Black Holes, and without Extragalactic Gamma-Ray Bursts. Or: What have we learned from all our recent observations, including the G-W Receptions, FRBs, and the EHT-Map? Do they fit into a consistent Scenario?

“…Their mass spectra have been published in the SDSS, updated in [Kormendy & Bender, 2011], and more recently in: the Messenger No.175 (2019), some 100 times enhanced, if you rename their 'SMBHs' 'BDs', =: Burning Disks. As is well explained in [Ponti et al, 2019] for our Milky Way, and in a certain way even for all galaxies around ours already in [Kundt & Krause, 1985], and again in [Kundt, 2017a], they show that matter inside the galactic disks spirals inward all the way to their centers, and is subsequently re-ejected -more or less explosively -through their halos via their BLRs, NLRs, EELs, ELRs, and/or jets towards their surroundings, via hot plasma streams; see also [Kundt 1978[Kundt , 1979[Kundt , 1985[Kundt , 1990[Kundt ,1996[Kundt , 2002[Kundt , 2013[Kundt , 2017a[Kundt , 2020. I.e., motion of matter in the disks of galaxies happens as (spiralling) infall, followed by stormy re-ejection.…”

“…The twin jet is again unresolved. For more detailed interpretations, please consult reference [Kundt, 2017a]. 8 now shows the remarkable fact that more matter has been ejected statistically from the galactic centers than has spiralled in; that galaxies on average lose mass with time, consistent with what was found already in [Kundt & Krause, 1985], via their Ly-alpha-forest spectra; the nuclear explosions inside the BDs are efficient, (as long as they contain enough (primordial) hydrogen).…”

“…Astrophysics without Black Holes, and without Extragalactic Gamma-Ray Bursts Wolfgang Kundt without a deep insight into their functioning, can give rise to very misleading results. Here I think in particular of the astrophysical jets of all (four) kinds [Kundt, 2017a], and next section, galactic rotations [Kundt, 2017b], supernovae, GRBs, (blowing) PSR winds [Kundt, 1998], PSR 'recycling', FRBs, forming the stars, planets, and moons (inside stellar disks), boosting the cosmic rays (=: CRs), creating thunderstorms, and many related phenomena. For a thorough understanding of them, we need quite specific education.…”

Gravitational Astrophysics

“…(BHs would grow with time, instead ). My most recent understanding of the functioning of our Galactic core -SgrA* -has appeared in [Kundt, 2017a]. It is not all that well described in the literature because its optical radiation is reduced by some 31 magnitudes of absorption by foreground dust, and because its radiation reaches us strongly weakened by having climbed out of the deepest potential well in our galaxy.…”
