Reports on direct evidence that supermassive black holes grow in conjunction with the galaxies they inhabit. Methodology to measure galactic age by analysis of color and intensity of starlight; Theories of Michael Merrifield and colleagues of billion-year-old black holes; Other observations published ...
Massive black holes in nuclei of galaxies and quasars In the first part of the paper the known results on the gravitational interaction of a massive black hole with the surrounding stars in a galactic nucleus ... Leonid,M.,Ozernoy,Michael,... - 《Astrophysics & Space Science》 被引量: ...
The analysis above indicates that the HI mass in galaxies is determined by the relative strength between the binding energy of the halo and the energy released from BHs (EBH ∝ MBH). The binding energy of the halo determines how much gas can be accreted onto the dark matter halo, whe...
The evidence therefore favors a joint galaxy and MBH evolution. The advances in observational cosmology and extragalactic astronomy have provided a large amount of data on quasars and their engines. We do know that MBHs are there, but we do not know how they got there. We also do not know...
A comparison with the upper limit to the luminosity of the nucleus of our Galaxy puts rather severe constraints on the mass of a hypothetical black hole at the galactic centre. Possible mechanisms preventing the formation and growth of black holes in normal galactic nuclei are discussed. The ...
It is well known that supermassive black holes (SMBHs) and their host galaxies co-evolve. A manifestation of this co-evolution is the correlation that has been found between the SMBH mass, <italic>M</italic>BH, and the galaxy bulge or stellar
It’s well known that all massive galaxies like the Milky Wayhost supermassive black holesmillions to billions of times the mass of the Sun in their centers. These galaxies and their black holes are intertwined, with the evolution of one significantly impacting the evolution of the other. ...
Minsley and collaborators found that within galaxies with active black holes, the ISM is warmer, the ratios of warm molecular gas to other coolants are larger, and other features from dust particles have a wider range of values than in galaxies where the black holes are dormant. ...
The first billion years of the Universe is a pivotal time: stars, black holes (BHs) and galaxies form and assemble, sowing the seeds of galaxies as we know them today. Detecting, identifying and understand- ing the first galaxies and BHs is one of the current observational and theoretical ...
