Super massive black holes in star forming gaseous circumnuclear discs
(2015)
Using Nbody/SPH simulations we study the evolution of the separation of a pair of SMBHs
embedded in a star forming circumnuclear disk (CNDa). This type of disk is expected to be formed
in the central kilo parsec of the ...
A high-velocity black hole on a Galactic-halo orbit in the solar neighbourhood
(Nature Publishing Group, 2001-12)
Only a few of the dozen or so known stellar-mass black holes have been observed away from the plane of the Galaxy1. Those few could have been ejected from the plane as a result of a ‘kick’ received during a supernova ...
Discovery of optical outflows and inflows in the black hole candidate GRS 1716−249
(2020)
We present optical spectroscopy obtained with the GTC, VLT, and SALT telescopes during the decline of the 2016–2017 outburst of the black hole candidate GRS 1716−249 (Nova Oph 1993). Our 18-epoch data set spans 6 months ...
Online control of enumeration strategies via bat algorithm and black hole optimization
(Springer Netherlands, 2017)
Stellar black holes at the dawn of the universe
(EDP Sciences, 2011-04)
Context. It is well established that between 380 000 and 1 billion years after the Big Bang the Inter Galactic Medium (IGM) underwent a “phase transformation” from cold and fully neutral to warm (≈ 104 K) and ionized. ...
Direct formation of supermassive black holes via multi-scale gas inflows in galaxy mergers
(2010)
Observations of distant quasars indicate that supermassive black holes of billions of solar masses already existed less than a billion years after the Big Bang1. Models in which the ‘seeds’ of such black holes form by the ...
