PROMISING CANDIDATE. “If such objects were to experience a rapid accretion event, they would be seen as (likely off-nuclear) ultra-luminous X-ray sources (ULXs). ULXs are common in star-forming regions and are often attributed to neutron stars or stellar black holes experiencing Eddington or super-Eddington accretion, or beamed emission.” (ULXs = ultra-luminous X-ray sources). https://lnkd.in/dYX7TQV View in LinkedIn

HIDDEN GENERATORS. “Our own Milky Way hosts such postulated objects; gas clouds near the Galactic Center possessing unusually large velocity dispersions are thought to harbor hidden IMBHs.” (IMBHs = intermediate mass black holes). https://lnkd.in/dYX7TQV View in LinkedIn

HUNTING THE SNARK. “Another avenue for hunting down IMBHs exists in off-center compact sources in large galaxies. The process of hierarchical merging results in the tidal disruption of low-mass galaxies as they enter larger halos. If those low-mass galaxies host IMBHs, the black holes will wander in the larger galaxy as they inspiral toward the center.” (IMBHs = intermediate mass black holes). https://lnkd.in/dYX7TQV View in LinkedIn

ORIGIN OF SUPERMASSIVE BLACK HOLES. “Population III stars are expected to be common in the early universe, forming in every galaxy in its first epochs of star formation. Direct collapse black holes, in contrast, are predicted to be more rare, because they require a special set of conditions in order to form.” https://lnkd.in/dYX7TQV View in LinkedIn

HEISENBERG, BOHR, AND EINSTEIN. “This exploration brought them in contact with a strange and unexpected reality that shattered the foundations of their world view and forced them to think in entirely new ways. The material world they observed no longer appeared as a machine, made up of a multitude of separate objects, but rather as an indivisible whole; a network of relationships that included the human observer in an essential way.” (Welcome to Wonderland!). https://lnkd.in/d9WF55y View in LinkedIn

ORIGINS OF HUGENESS. “Several theories have been postulated for the origin of SMBH seeds. Some of the leading candidates are: (a) Population III star remnants (100–1000 M⊙, form at 15 < z < 30), (b) Direct collapse black holes (104–106 M⊙, form at 10 < z < 20), and (c) Collapsing stellar clusters (∼103 M⊙, form at high or low z).” (M⊙ = unit of celestial mass; SMBH = supermassive black hole). https://lnkd.in/dYX7TQV View in LinkedIn

WHAT PERSPECTIVE!! “The idea of IMBHs as SMBH seeds is appealing because of the sheer difficulty in creating a 109 M⊙ SMBH in less than one billion years.” (IMBHs = intermediate mass black holes; SMBH = supermassive black holes). https://lnkd.in/dYX7TQV View in LinkedIn

FILLING THE GAP. “The Laser Interferometer Space Antenna (LISA) will demystify IMBHs by detecting the mergers of these objects out to extremely high redshifts, while measuring their masses with extremely high precision. These observations of merging IMBHs will allow us to constrain the formation mechanism and subsequent evolution of massive black holes, from the ‘dark ages’ to the present day.” (IMBHs = intermediate mass black holes). https://lnkd.in/dYX7TQV View in LinkedIn

SIMILAR APPROACHES. “Similar approaches have been previously used to describe the biosphere-level metabolic changes that accompanied the transition to an oxic atmosphere, about 2.2 billion years ago.” https://lnkd.in/dcwZe7b View in LinkedIn
