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…
Shedding light on low-mass subhalo survival and annihilation luminosity with numerical simulations
Alejandra Aguirre-Santaella, Miguel A. Sánchez-Conde, Go Ogiya +2
In this work, we carry out a suite of specially-designed numerical simulations to shed further light on dark matter (DM) subhalo survival at mass scales relevant for gamma-ray DM s…
Tidal Stripping in the Adiabatic Limit
Jens Stücker, Go Ogiya, Raul E. Angulo +2
We present a model for the remnants of haloes that have gone through an adiabatic tidal stripping process. We show that this model exactly reproduces the remnant of an NFW halo tha…
Dark matter cores in massive high- galaxies formed by baryonic clumps
Go Ogiya, Daisuke Nagai
The rotation curves of some star forming massive galaxies at redshift two decline over the radial range of a few times the effective radius, indicating a significant deficit of dar…
Evolution of Massive Black Hole Binaries in Collisionally Relaxed Nuclear Star Clusters -- Impact of Mass Segregation
Diptajyoti Mukherjee, Qirong Zhu, Go Ogiya +2
Massive Black Hole (MBH) binaries are considered to be one of the most important sources of Gravitational Waves (GW) that can be detected by GW detectors like LISA. However, there…
