Tidal Stripping of a White Dwarf by an Intermediate-mass Black Hole

open access: yesThe Astrophysical Journal, 2023
During the inspiralling of a white dwarf (WD) into an intermediate-mass black hole (∼10 ^2−5 M _⊙ ), both gravitational waves (GWs) and electromagnetic (EM) radiation are emitted.

Intermediate-mass black holes in Globular Clusters

open access: yes, 2013
For a sample of nine Galactic globular clusters we measured the inner kinematic profiles with integral-field spectroscopy that we combined with existing outer kinematic measurements and HST luminosity profiles. With this information we are able to detect the crucial rise in the velocity-dispersion profile which indicates the presence of a central black

Looking for Intermediate-Mass Black Holes [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2010
A discussion of the entropy of the universe leads to the suggestion of very many intermediate-mass black holes between thirty and three hundred thousand solar masses in the halo. It is consistent with observations on wide binaries as well as microlensing and considerations of disk stability that such IMBHs constitute all cold dark ...

Primordial intermediate mass black holes as dark matter [PDF]

open access: yesInternational Journal of Modern Physics A, 2020
Among particle theory candidates for the dark matter constituents. Axions and WIMPs are the most popular. In this paper, we discuss these then focus on our preferred astrophysical candidate, the Primordial Intermediate Mass Black Holes in the acronym DM[Formula: see text]=[Formula: see text]PIMBHs.

Tracing intermediate-mass black holes in the Galactic Centre [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2007
AbstractWe have developed a new method for post-Newtonian, high-precision integration of stellar systems containing a super-massive black hole (SMBH), splitting the forces on a particle between a dominant central force and perturbations. We used this method to perform fully collisional N-body simulations of inspiralling intermediate-mass black holes ...

Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam

open access: yesAdvanced Engineering Materials, EarlyView.
Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.

Optically thick winds of very massive stars suppress intermediate-mass black hole formation

open access: yesAstronomy & Astrophysics
Intermediate-mass black holes (IMBHs) are the link between stellar-mass and supermassive black holes. Gravitational waves have started to unveil a population of IMBHs in the ~100–300 M⊙ range. Here, we investigate the formation of IMBHs from non-rotating

The Black Hole Spin Controversy [PDF]

open access: yes, 2012
Astrophysical black holes are the simplest possible objects. They are completely described by only two parameters in general relativity, their mass and the specific angular momentum, spin.

Numerical Simulations of Black-Hole Spacetimes [PDF]

open access: yes, 2012
This thesis covers various aspects of the numerical simulation of black-hole spacetimes according to Einstein's general theory of relativity, using the Spectral Einstein Code developed by the Caltech-Cornell-CITA collaboration.
