Modelling feedback from stars and black holes in galaxy mergers [PDF]

open access: yes, 2004
We describe techniques for incorporating feedback from star formation and black hole (BH) accretion into simulations of isolated and merging galaxies. At present, the details of these processes cannot be resolved in simulations on galactic scales.

The effect of the metallicity-specific star formation history on double compact object mergers [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
We investigate the impact of uncertainty in the metallicity-specific star formation rate over cosmic time on predictions of the rates and masses of double compact object mergers observable through gravitational waves.

Gravitational waves from neutron star mergers and their relation to the nuclear equation of state [PDF]

open access: yesProgress in Particle and Nuclear Physics, 2019
In this article, I introduce ideas and techniques to extract information about the equation of state of matter at very high densities from gravitational waves emitted before, during and after the merger of binary neutron stars. I also review current work

Efficiency-Enhancing Horizontal Mergers in Spatial Competition with Network Externalities

open access: yesMathematics, 2022
We study horizontal mergers in a network products market with a three-firm model of spatial competition, where two merged firms become compatible at the expense of product differentiation.

Does company performance really improve following mergers? A pre-post analysis of differences in Greece [PDF]

open access: yesProblems and Perspectives in Management, 2022
Merger transactions occur in various business sectors and are a drastic way of corporate restructuring. For several companies, mergers are the only path to gaining access to new resources, improving profitability, and achieving business excellence.

Major Mergers and the Origin of Elliptical Galaxies [PDF]

open access: yes, 2003
The formation of elliptical galaxies as a result of the merging of spiral galaxies is discussed. We analyse a large set of numerical N-Body merger simulations which show that major mergers can in principle explain the observed isophotal fine structure of

2-OGC: Open Gravitational-wave Catalog of Binary Mergers from Analysis of Public Advanced LIGO and Virgo Data [PDF]

open access: yesAstrophysical Journal, 2019
We present the second Open Gravitational-wave Catalog (2-OGC) of compact-binary coalescences, obtained from the complete set of public data from Advanced LIGO’s first and second observing runs. For the first time we also search public data from the Virgo

Organisational change and the psychological contract at a pharmaceutical company

open access: yesSA Journal of Human Resource Management, 2017
Orientation: Over a period of 6 years, a South African pharmaceutical company had been involved in several mergers and acquisitions. These changes had proved difficult for staff and staff attrition had risen. Research purpose: The objective of the study

Progenitors of gravitational wave mergers: binary evolution with the stellar grid-based code ComBinE [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
The first gravitational wave detections of mergers between black holes and neutron stars represent a remarkable new regime of high-energy transient astrophysics. The signals observed with LIGO-Virgo detectors come from mergers of extreme physical objects
