Rates of Compact Object Coalescences [PDF]
Living Reviews in Relativity, 2022 AbstractGravitational-wave detections are enabling measurements of the rate of coalescences of binaries composed of two compact objects—neutron stars and/or black holes. The coalescence rate of binaries containing neutron stars is further constrained by electromagnetic observations, including Galactic radio binary pulsars and short gamma-ray bursts ...

We study the collisions of compact objects induced by neutron star (NS) birth kicks. If a binary system survives the first supernova (SN) explosion, in some cases the second SN may place the stellar remnants into bound highly eccentric orbits. The two compact objects will tidally interact and quickly spiral into each other. We expect such encounters to

Abstract When a star is near the end of its lifetime, and all of its fuel is used up, there is no longer enough outwards pressure due to radiation to resist the inwards pull of gravity and the star starts to collapse again. However, there is another source of internal pressure.

The trapping of neutrinos in strong gravitational fields is considered. The zero-mass Dirac equation for curved space-time is specialized to the case of a static spherically symmetric object of constant density. The WKB method is applied to obtain the energy spectrum of the semibound states of the neutrinos.

Salient object detection via compactness and objectness cues
The Visual Computer, 2017Existing saliency detection algorithms are mainly patch-based. In this paper, we propose a simple but effective approach to detect salient objects by exploring both patch-level and object-level cues. First, we obtain the objectness saliency map with objectness algorithm to find potential object candidates without need of category information.

In this chapter we first present a review of the methods for the tomographie reconstruction of a compact homogeneous object that lies in a homogeneous background. Then we focus on contour estimation and polyhedral shape reconstructions. We give some sufficient conditions to obain exact reconstructions from a complete set of projections in the 2.1) case

Non-compact astronomical objects as microlenses
Astronomical & Astrophysical Transactions, 1997Abstract The microlensing of the distant stars by neutralino stars is considered. The neutralino sars have been considered in the recent paper of Gurevich and Zybin; moreover, it has been suggested that the stars should be regard as a major component of dark matter.

Parallel algorithms on compact binary objects
Proceedings of the 12th IAPR International Conference on Pattern Recognition (Cat. No.94CH3440-5), 2002For SIMD computers, using virtual processors, a common strategy for mapping the processors on the image data is to apply one processor per pixel. For operations on gray level images it is a good approach, but for operations on binary images many of the available processors are idle and not used in the calculation. This paper presents some common binary
