Monetary Policy across the Wealth Distribution

Alessandro Franconi, Giacomo Rella

Using vector autoregression and the Distributional Financial Accounts of the United States, we show that monetary policy has unequal effects across the wealth distribution. The direction and persistence of these effects depend on the policy instrument and the wealth group. Interest rate cuts initially reduce wealth inequality but increase it in the medium run. Asset purchases, instead, increase wealth inequality but only temporarily. Housing is the main channel through which monetary policy affects wealth at the bottom. The effects of monetary policy on capital gains are larger at the top due to heterogeneous portfolios. (Stone Center on Socio-Economic Inequality Working Paper)

Magnetic braking during direct collapse black hole formation

Muhammad A. Latif, Dominik R. G. Schleicher

Magnetic fields are expected to be efficiently amplified during the formation of the first massive black holes via the small-scale dynamo and in the presence of strong accretion shocks occurring during gravitational collapse. Here, we analyze high-resolution cosmological magneto-hydrodynamical simulations of gravitational collapse in atomic cooling halos, exploring the dynamical role of magnetic fields, particularly concerning the effect of magnetic braking and angular momentum transport. We find that after the initial amplification, magnetic fields contribute to the transport of angular momentum and reduce it compared to pure hydrodynamical simulations. However, the magnetic and Reynolds torques do not fully compensate for the inward advection of angular momentum, which still accumulates over timescales of ∼1~Myr. A Jeans analysis further shows that magnetic pressure strongly contributes to suppressing fragmentation on scales of 0.1−10~pc. Overall, the presence of magnetic fields thus aids in the transport of angular momentum and favors the formation of massive objects.

VINTERGATAN-GM: How do mergers affect the satellite populations of MW-like galaxies?

Gandhali D. Joshi, Andrew Pontzen, Oscar Agertz, Martin P. Rey, Justin Read, Florent Renaud

We investigate the impact of a galaxy’s merger history on its system of satellites using the new \textsc{vintergatan-gm} suite of zoom-in hydrodynamical simulations of Milky Way-mass systems. The suite simulates five realizations of the same halo with targeted `genetic modifications’ (GMs) of a z≈2 merger, but resulting in the same halo mass at z=0. We find that differences in the satellite stellar mass functions last for 2.25-4.25 Gyr after the z≈2 merger; specifically, the haloes that have undergone smaller mergers host up to 60% more satellites than those of the larger merger scenarios. However, by z=0 these differences in the satellite stellar mass functions have been erased. The differences in satellite numbers seen soon after the mergers are driven by several factors, including the timings of major mergers, the masses and satellite populations of the central and merging systems, and the subsequent extended history of minor mergers. The results persist when measured at fixed central stellar mass rather than fixed time, implying that a host’s recent merger history can be a significant source of scatter when reconstructing its dynamical properties from its satellite population.
