Description
James Webb Space Telescope (JWST) discovered remarkably numerous Little Red Dots (LRDs) in the Universe for a wide redshift z range from ~2 to ~7. Such LRDs, characterized by prominent V shaped continuum spectra with unusually broad Hα and Hβ lines (FWHM ~10^3 to ~10^4 km/s), are inferred to be extremely luminous, compact, massive, metal poor yet without detectable X-ray and radio emissions. We have been working on self-similar dynamic formation of black holes in a wide mass range within giant mass reservoirs containing normal and dark matters in general. In particular, we predicted the possibility of hypermassive black holes (HMBHs; ~10^{10} to 10^{12} solar masses or even higher) and supermassive black holes (SMBHs; ~10^{6} to several 10^{9} solar masses) in the Universe including the early Universe. We also suggested the progenitors of the LIGO/Virgo black holes in the forbidden mass zone, magnetars, and classes of supernovae, γ-ray bursts, X-ray bursts, fast radio bursts are likely to be magnetized massive stars. As a CUSPEA scholar of 1980, I also share anecdotes of Professor T. D. Lee.
