High-redshift AGN population in radiation-hydrodynamics simulations

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Teodora-Elena Bulichi, Teodora-Elena Bulichi, , , | Summary: High-redshift active galactic nuclei (AGN) have long been recognized as key probes of early black hole growth and galaxy evolution. However, modeling this population remains difficult due to the wide range of luminosities and black hole masses involved, and […]

Odd-even parity dependent transport in an annular Kitaev chain

Kavli Affiliate: Gang Su | First 5 Authors: Wei Wang, Wei Wang, , , | Summary: We investigate the impact of magnetic flux and the odd-even parity of lattice points $N$ on electron transport in an annular Kitaev chain, with an explanation provided from the energy band perspective. Three transport mechanisms including direct transmission (DT), […]

Efficient Branch-and-Bound for Submodular Function Maximization under Knapsack Constraint

Kavli Affiliate: Yi Zhou | First 5 Authors: Yimin Hao, Yimin Hao, , , | Summary: The submodular knapsack problem (SKP), which seeks to maximize a submodular set function by selecting a subset of elements within a given budget, is an important discrete optimization problem. The majority of existing approaches to solving the SKP are […]

The Discovery of Little Red Dots in the Local Universe: Signatures of Cool Gas Envelopes

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Xiaojing Lin, Xiaojing Lin, , , | Summary: JWST observations have revealed a population of high-redshift "little red dots" (LRDs) that challenge conventional AGN models. We report the discovery of three local LRDs at $z = 0.1-0.2$, initially selected from the SDSS database, with follow-up optical/near-IR spectroscopy […]
