The Irreversible Depletion of Dark Matter Spikes by Extreme-Mass-Ratio Inspirals
Charlie Sharpe, Yonadav Barry Ginat, Thomas F. M. Spieksma +2
Dense dark matter spikes around massive black holes (MBHs) have been widely predicted to produce gravitational-wave dephasing in extreme-mass-ratio inspirals (EMRIs) that are poten…
On the rates of binary star collisions around hypermassive black holes
Megha Sharma, Alexander Heger, Evgeni Grishin +1
Observations of the Milky Way show that galaxies have binary stars in their centres. Using Monte Carlo simulations, we model the population statistics of encounters of such binarie…
Are most detected tidal disruption events partial?
Megha Sharma, Daniel J. Price, Alexander Heger +1
During a tidal disruption event (TDE), a star loses mass due to the tidal gravitational forces of the black hole. In a partial tidal disruption event, a stellar remnant is left beh…
A benchmark for binary star interaction with a supermassive black hole in general relativity
Megha Sharma, Alexander Heger, Daniel J. Price +4
Most galaxies have supermassive black holes (SMBH) at their centres, surrounded by stars with binary systems also present in this environment. We use two schemes - post-Newtonian (…
The deci-Hz gravitational wave signal from the collapse of rotating very massive stars
Bailey Sykes, Jade Powell, Bernhard Müller +1
We calculate the gravitational wave signal from the collapse of a rotating 300 star at the upper end of the pair-instability regime. The large-scale asymmetries that deve…
Crust composition and the Shallow Heat Source in KS 1731-260
R. Jain, E. F. Brown, H. Schatz +11
The presence of a strong shallow heat source of unknown origin in accreting neutron star crusts has been inferred by analyzing X-ray observations of their cooling in quiescence. We…
Neutron star kicks plus rockets as a mechanism for forming wide low-eccentricity neutron star binaries
Ryosuke Hirai, Philipp Podsiadlowski, Alexander Heger +1
Recent neutron star surface observations corroborate a long-standing theory that neutron stars may be accelerated over extended periods after their birth. We analyze how these prol…
Convection and the Core -mode in Proto-Compact Stars -- A detailed analysis
Pia Jakobus, Bernhard Mueller, Alexander Heger
We present a detailed analysis of the dynamics of proto-compact star (PCS) convection and the core -mode in core-collapse supernovae based on general relativistic 2D and…
Supernova Simulations from a 3D Progenitor Model -- Impact of Perturbations and Evolution of Explosion Properties
B. Müller, T. Melson, A. Heger +1
We study the impact of large-scale perturbations from convective shell burning on the core-collapse supernova explosion mechanism using three-dimensional (3D) multi-group neutrino…
The Effect of Pair-Instability Mass Loss on Black Hole Mergers
K. Belczynski, A. Heger, W. Gladysz +9
Mergers of two stellar origin black holes are a prime source of gravitational waves and are under intensive investigations. One crucial ingredient in their modeling has so far been…
A Simple Approach to the Supernova Progenitor-Explosion Connection
B. Müller, A. Heger, D. Liptai +1
We present a new approach to understand the landscape of supernova explosion energies, ejected nickel masses, and neutron star birth masses. In contrast to other recent parametric…
