Black holes in the milky way galaxy.
نویسنده
چکیده
Extremely strong observational evidence has recently been found for the presence of black holes orbiting a few relatively normal stars in our Milky Way Galaxy and also at the centers of some galaxies. The former generally have masses of 4-16 times the mass of the sun, whereas the latter are "supermassive black holes" with millions to billions of solar masses. The evidence for a supermassive black hole in the center of our galaxy is especially strong.

Creation of Spiral Galaxies Ii
The spiral galaxies, including our galaxy, are created by the gravito-radiative forces generated by colliding black holes at the center of quasars. The gravito-radiative force is predicted by Einstein’s general theory of relativity. A quasar is assumed to have a circular disk of highly compressed neutrons (ylem) orbiting around black holes. The collision of two black holes at the center generat...
متن کاملX-Rays from Isolated Black Holes in the Milky Way
Galactic stellar-population-synthesis models, chemical-enrichment models, and longduration Bulge microlensing events indicate about Ntot = 10 − 10 stellar-mass black holes reside in our Galaxy. We study X-ray emission from accretion from the interstellar medium on to isolated black holes. Although isolated black holes may be fewer in number than neutron stars, NNS ∼ 10, their higher masses, 〈M〉...
متن کاملA Cluster of Black Holes at the Galactic Center
If the stellar population of the bulge contains black holes formed in the final core collapse of ordinary stars with M ∼> 30M⊙, then about 25,000 stellar mass black holes should have migrated by dynamical friction into the central parsec of the Milky Way, forming a black hole cluster around the central supermassive black hole. These black holes can be captured by the central black hole when the...
متن کاملQuasar Feedback and Galactic - scale Outflows
One of the most fascinating astronomical discoveries of the last several decades was the gradual realization that almost every massive galaxy, including our own Milky Way, contains a supermassive black hole in its center. Several lines of evidence suggest a fundamental connection between the black holes residing in galaxy centers and the formation and evolution of their host galaxies. One such ...
متن کاملConstraints on massive black holes as dark matter candidates using Galactic globular clusters
This work considers the idea of massive black holes being the constituents of the Galactic dark matter halo. It constrains the maximum black hole mass to MBH ∼ 5× 10 M by examining their influence on the population of globular clusters in our Milky Way. In the adopted halo model, globular clusters are exposed to constant bombardment of halo objects on their orbits through the Galaxy and thus wi...
