Radio Scrutiny of the X-ray-Weak Tail of Low-Mass Active Galactic Nuclei: A Novel Signature of High-Eddington Accretion?

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jeremiah D. Paul, Richard M. Plotkin, W. N. Brandt, Christopher H. Ellis, Elena Gallo | Summary: The supermassive black holes ($M_{rm BH} sim 10^{6}$$-$$10^{10}~M_odot$) that power luminous active galactic nuclei (AGNs), i.e., quasars, generally show a correlation between thermal disk emission in the ultraviolet (UV) and […]

Atomic evolution of hydrogen intercalation wave dynamics in palladium nanocrystals

Posted by dbos Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Daewon Lee, Sam Oaks-Leaf, Sophia B. Betzler, Yifeng Shi, Siyu Zhou | Summary: Solute-intercalation-induced phase separation creates spatial heterogeneities in host materials, a phenomenon ubiquitous in batteries, hydrogen storage, and other energy devices. Despite many efforts, probing intercalation processes at the atomic scale has been a […]

Revealing kinetically tuned atomic pathways for interfacial strain relaxation

Posted by dbos Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Sophia B. Betzler, Daewon Lee, Sam Oaks-Leaf, Colin Ophus, Lin-Wang Wang | Summary: Strain at interfaces may profoundly impact the microstructure and properties of materials; thus, it is a major consideration when designing and engineering materials. Dislocation formation is a commonly known mechanism to release mismatch […]

No need to know: astrophysics-free gravitational-wave cosmology

Posted by dbos Chicago

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Amanda M. Farah, Thomas A. Callister, Jose María Ezquiaga, Michael Zevin, Daniel E. Holz | Summary: Gravitational waves from merging compact objects encode direct information about the luminosity distance to the binary. When paired with a redshift measurement, this enables standard-siren cosmology: a Hubble diagram can […]

Resolving the nature and putative nebular emission of GS9422: an obscured AGN without exotic stars

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Sandro Tacchella, William McClymont, Jan Scholtz, Roberto Maiolino, Xihan Ji | Summary: Understanding the sources that power nebular emission in high-redshift galaxies is fundamentally important not only for shedding light onto the drivers of reionisation, but to constrain stellar populations and the growth of black holes. Here […]

Structural, magnetic and magnetocaloric properties of triangular-lattice transition-metal phosphates

Posted by dbos UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Chuandi Zhang, Junsen Xiang, Quanliang Zhu, Longfei Wu, Shanfeng Zhang | Summary: The recent discovery of the spin supersolid candidate Na$_2$BaCo(PO$_4$)$_2$ stimulates numerous research interest on the triangular-lattice transition-metal phosphates. Here we report a comprehensive study on the structural, magnetic and magnetocaloric properties of polycrystalline Na$_2$$A$$T$(PO$_4$)$_2$ ($A$ […]
