Probing wandering black holes with off-nuclear tidal disruption events
The hierarchical assembly of galaxies and dynamics in galactic nuclei naturally predict a significant population of off-nuclear massive black holes (MBHs), yet direct observational evidence remains scarce. The demographics of these off-nuclear MBHs offer critical insights into the formation of MBH mergers, the nature of ultra-compact dwarf galaxies, and the co-evolution of MBHs and their host g...

Local Group Analogs in a cosmological context: Relating the velocity structure to the cosmic web
The Local Group (LG), as a gravitationally bound system of the Milky Way and Andromeda, as well as their satellites, is a cornerstone of near-field cosmology. However, its utility as a cosmological probe requires understanding how it is related to the cosmic web. Using the ABACUSSUMMIT simulation, we identify LG analogues and quantify their environmental dependence. We find that the coupling en...
