Examining the effects of dark matter spikes on eccentric intermediate mass ratio inspirals using N-body simulations
Diptajyoti Mukherjee, A. Miguel Holgado, Go Ogiya +1
Recent studies suggest that dark matter (DM) spikes around intermediate-mass black holes could cause observable dephasing in gravitational wave (GW) signals from Intermediate Mass…
Formation of dense filaments induced by runaway supermassive black holes
Go Ogiya, Daisuke Nagai
A narrow linear object extending from the centre of a galaxy at redshift has recently been discovered and interpreted as shocked gas filament formi…
Searching for clues of past binary supermassive black hole mergers in nuclear star clusters
Alessandra Mastrobuono-Battisti, Go Ogiya, Oliver Hahn +1
Galaxy mergers are common processes in the Universe. As a large fraction of galaxies hosts at their centres a central supermassive black hole (SMBH), mergers can lead to the format…
The effect of stellar encounters on the dark matter annihilation signal from prompt cusps
Jens Stücker, Go Ogiya, Simon D. M. White +1
Prompt cusps are the densest quasi-equilibrium dark matter objects; one forms at the instant of collapse within every isolated peak of the initial cosmological density field. They…
