Testing the galaxy collision induced formation scenario for the trail of dark matter deficient galaxies with the susceptibility of globular clusters to the tidal force
Go Ogiya, Frank C. van den Bosch, Andreas Burkert +1
It has been suggested that a trail of diffuse galaxies, including two dark matter deficient galaxies (DMDGs), in the vicinity of NGC1052 formed because of a high-speed collision be…
Evolution of subhalo orbits in a smoothly-growing host halo potential
Go Ogiya, James E. Taylor, Michael J. Hudson
The orbital parameters of dark matter (DM) subhaloes play an essential role in determining their mass-loss rates and overall spatial distribution within a host halo. Haloes in cosm…
Dynamical self-friction: how mass loss slows you down
Tim B. Miller, Frank C. van den Bosch, Sheridan B. Green +1
We investigate dynamical self-friction, the process by which material that is stripped from a subhalo torques its remaining bound remnant, which causes it to lose orbital angular m…
Accelerated orbital decay of supermassive black hole binaries in merging nuclear star clusters
Go Ogiya, Oliver Hahn, Chiara M. F. Mingarelli +1
The coalescence of supermassive black holes (SMBHs) should generate the strongest sources of gravitational waves (GWs) in the Universe. However, the dynamics of their coalescence i…
DASH: a library of dynamical subhalo evolution
Go Ogiya, Frank C. van den Bosch, Oliver Hahn +3
The abundance and demographics of dark matter substructure is important for many areas in astrophysics and cosmological -body simulations have been the primary tool used to inve…
Tidal stripping as a possible origin of the ultra diffuse galaxy lacking dark matter
Go Ogiya
Recent observations revealed a mysterious ultra diffuse galaxy, NGC1052-DF2, in the group of a large elliptical galaxy, NGC1052. Compared to expectations from abundance matching mo…
