Abstract
We describe the formation of a seed massive black hole (MBH) inside a supermassive star (SMS) in a distant galactic nucleus. The short-lived SMS is naturally formed due to collision destructions of normal stars in the evolving galactic nucleus. The neutron stars (NSs) and stellar-mass black holes form a compact self-gravitating subsystem deep inside a SMS. This subsystem is short-lived in comparison with a host SMS and collapses finally into the MBH. Just before gravitational collapse of compact subsystem the frequent NS collisions are accompanied by the generation of numerous ultra-relativistic fireballs. A combined ram pressure of multiple coexisting fireballs produces a quasi-stationary rarefied cavity in the central part of SMS. The protons are accelerated in the fireballs and by relativistic shocks in the cavity. All secondary particles, produced in collisions, except the high-energy neutrinos are absorbed in the SMS interiors. An estimated high-energy neutrino signal from this hidden source can be detected by the neutrino telescope with an effective area $S\sim1$ km2 providing the evidence for MBH formation in a distant galactic nucleus. A corresponding lifetime of this high-energy hidden neutrino source is ~0.1-1 yr.


Key words: neutrinos -- black hole physics -- acceleration of particles

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
