Small Region, Big Impact: Highly Anisotropic Lyman-continuum Escape from a Compact Starburst Region with Extreme Physical Properties

Posted by May 22, 2023Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Keunho J. Kim, Matthew B. Bayliss, Jane R. Rigby, Michael D. Gladders, John Chisholm | Summary: Extreme, young stellar populations are considered the primary contributor to cosmic re-ionization. How Lyman-continuum (LyC) escapes these galaxies remains highly elusive, and it is challenging to observe this process in […]

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Keunho J. Kim, Matthew B. Bayliss, Jane R. Rigby, Michael D. Gladders, John Chisholm | Summary: Extreme, young stellar populations are considered the primary contributor to cosmic reionization. However, how Lyman-continuum (LyC) escapes these galaxies remains highly elusive because LyC escape can vary on sub-galactic scales […]

Acousto-magnonic Hall effect in honeycomb antiferromagnets

Posted by klaurent May 22, 2023UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Ryotaro Sano, Yuya Ominato, Mamoru Matsuo, , | Summary: The recently discovered van der Waals antiferromagnets have suffered from the lack of a comprehensive method to study their magnetic properties. Here, we propose a dissipationless magnon spin Hall current driven by surface acoustic waves as a novel […]

Structural, optical, and thermal properties of BN thin films grown on diamond via pulsed laser deposition

Posted by dbos May 22, 2023Cornell

Kavli Affiliate: Zhiting Tian | First 5 Authors: Abhijit Biswas, Gustavo A. Alvarez, Tao Li, Joyce Christiansen-Salameh, Eugene Jeong | Summary: Heterostructures based on ultrawide-bandgap (UWBG) semiconductors (bandgap >4.0 eV), boron nitride (BN) and diamond are important for next-generation high-power electronics. However, in-situ hetero-epitaxy of BN/diamond or vice-versa remains extremely challenging, due to their non-trivial […]

Transferable screened range-separated hybrid functionals for electronic and optical properties of van der Waals materials

Posted by dbos May 22, 2023Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: María Camarasa-Gómez, Ashwin Ramasubramaniam, Jeffrey B. Neaton, Leeor Kronik, | Summary: The accurate description of electronic properties and optical absorption spectra is a long-standing challenge for density functional theory. Recently, the introduction of screened range-separated hybrid (SRSH) functionals for solid-state materials has allowed for the calculation […]

Clustering of Primordial Black Holes from QCD Axion Bubbles

Posted by klaurent May 22, 2023Tokyo

Kavli Affiliate: Masahiro Kawasaki | Summary:We study the clustering of primordial black holes (PBHs) and axion miniclusters produced in the model proposed to explain the LIGO/Virgo events or the seeds of the supermassive black holes (SMBHs) in arXiv:2006.13137. It is found that this model predicts large isocurvature perturbations due to the clustering of PBHs and […]

Incomplete inverse problem for Dirac operator with constant delay

Posted by klaurent May 22, 2023May 30, 2023Berkeley

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 […]

Unveiling the small-scale jets in the rapidly growing supermassive black hole IZw1

Posted by klaurent May 21, 2023Peking

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 […]
