Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: In this work, we consider Dirac-type operators with a constant delay less than two-fifths of the interval and not less than one-third of the interval. For our considered Dirac-type operators, an incomplete inverse spectral problem is studied. Specifically, when two complex […]

Kavli Affiliate: Ran Wang | First 5 Authors: Xiaolong Yang, Su Yao, Luigi C. Gallo, Jun Yang, Luis C. Ho | Summary: Accretion of black holes at near-Eddington or super-Eddington rates is the most powerful episode that drives black hole growth, and it may work in several types of objects. However, the physics of accretion […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Raffaella Schneider, Rosa Valiante, Alessandro Trinca, Luca Graziani, Marta Volonteri | Summary: JWST is unveiling for the first time accreting black holes (BHs) with masses of 10^6 – 10^7 Msun at z > 4, with the most distant residing in GNz11 at z = 10.6. Are we […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Roberto Maiolino, Jan Scholtz, Joris Witstok, Stefano Carniani, Francesco D’Eugenio | Summary: Multiple theories have been proposed to describe the formation of black hole seeds in the early Universe and to explain the emergence of very massive black holes observed in the first billion years after Big […]
Kavli Affiliate: Erin Kara | First 5 Authors: Yerong Xu, Ciro Pinto, Daniele Rogantini, Stefano Bianchi, Matteo Guainazzi | Summary: Ultra-fast outflows (UFOs) have been revealed in a large number of active galactic nuclei (AGN) and are regarded as promising candidates for AGN feedback on the host galaxy. The nature and launching mechanism of UFOs […]

Kavli Affiliate: Debora Sijacki | First 5 Authors: Jake S. Bennett, Debora Sijacki, Tiago Costa, Nicolas Laporte, Callum Witten | Summary: High-redshift quasars ($zgtrsim6$), powered by black holes (BHs) with large inferred masses, imply rapid BH growth in the early Universe. The most extreme examples have inferred masses of $sim ! 10^9,$M$_odot$ at $z = […]
