Magnetic Flux Transport in Radiatively Inefficient Accretion Flows and the Pathway towards a Magnetically Arrested Disk |
Abstract: Large-scale magnetic fields play a vital role in determining the angular
momentum transport and in generating jets/outflows in the accreting systems,
yet their origin remains poorly understood. We focus on radiatively inefficient
accretion flows (RIAF) around the black holes, and conduct three-dimensiona... | https://export.arxiv.org/pdf/2208.02269 | .

The effect of magnetic field on the inner Galactic rotation curve |
Abstract: In the past few decades, some studies pointed out that magnetic field might

Abstract: Lyman Break Galaxy (LBG) candidates at $z\gtrsim12$ are rapidly being

neutral hydrogen absorption of rest-frame UV photons, these sources are
