Tracing the Evolution of SMBHs and Stellar Objects in Galaxy Mergers: A Multi-mass Direct N-body Model

open access: yesThe Astrophysical Journal, 2023
By using direct N -body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how different stellar components evolve during the merger, we

The Dynamics of White Dwarfs, Black Holes and Stellar Cusps [PDF]

open access: yes, 2013
This thesis contains topics related mostly to the dynamics of white dwarfs (chapter 2), the dynamics of stars around binary super massive black holes (chapters 4, 5 and 6) and dynamics in the singular isothermal sphere (chapter 7).

THE CLOSE STELLAR COMPANIONS TO INTERMEDIATE-MASS BLACK HOLES [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT When embedded in dense cluster cores, intermediate-mass black holes (IMBHs) acquire close stellar or stellar-remnant companions. These companions are not only gravitationally bound, but also tend to hierarchically isolate from other cluster stars through series of multibody encounters.

Intermediate-Mass Black Holes: The Essential Population to Explore the Unified Model for Accretion and Ejection Processes

open access: yesGalaxies, 2023
We study radio and X-ray emissions from intermediate-mass black holes (IMBHs) and explore the unified model for accretion and ejection processes. The radio band survey of IMBH (candidate) hosted galaxies indicates that only a small fraction (∼0.6%) of ...

RETENTION OF STELLAR-MASS BLACK HOLES IN GLOBULAR CLUSTERS [PDF]

open access: yesThe Astrophysical Journal, 2013
Globular clusters should be born with significant numbers of stellar-mass black holes (BHs). It has been thought for two decades that very few of these BHs could be retained through the cluster lifetime. With masses ~10 MSun, BHs are ~20 times more massive than an average cluster star.

Investigating stellar-mass black hole kicks [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2012
We investigate whether stellar-mass black holes have to receive natal kicks in order to explain the observed distribution of low-mass X-ray binaries containing black holes within our Galaxy. Such binaries are the product of binary evolution, where the massive primary has exploded forming a stellar-mass black hole, probably after a common envelope phase

Templates for stellar mass black holes falling into supermassive black holes [PDF]

open access: yesClassical and Quantum Gravity, 2003
The spin modulated gravitational wave signals, which we shall call smirches, emitted by stellar mass black holes tumbling and inspiralling into massive black holes have extremely complicated shapes. Tracking these signals with the aid of pattern matching techniques, such as Wiener filtering, is likely to be computationally an impossible exercise.

A Global Inventory of Feedback

open access: yesGalaxies, 2023
Feedback from both supermassive black holes and massive stars plays a fundamental role in the evolution of galaxies and the inter-galactic medium. In this paper, we use available data to estimate the total amount of kinetic energy and momentum created ...
