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…

Physical and numerical stability and instability of AGN bubbles in a hot intracluster medium
Go Ogiya, Pawel Biernacki, Oliver Hahn +1
While feedback from Active Galactic Nuclei (AGN) is an important heating source in the centre of galaxy clusters, it is still unclear how the feedback energy is injected into the i…

Dark Matter Substructure in Numerical Simulations: A Tale of Discreteness Noise, Runaway Instabilities, and Artificial Disruption
Frank C. van den Bosch, Go Ogiya
To gain understanding of the complicated, non-linear and numerical processes associated with the tidal evolution of dark matter subhaloes in numerical simulation, we perform a larg…
