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

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 (GWs) 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 […]

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

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

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$ ($A$ […]

A mathematical theory of relational generalization in transitive inference

Kavli Affiliate: Vincent Ferrera | Authors: Samuel Lippl, Kenneth Kay, Greg Jensen, Vincent P. Ferrera and L.F. Abbott | Summary: Humans and animals routinely infer relations between different items or events and generalize these relations to novel combinations of items (“compositional generalization”). This allows them to respond appropriately to radically novel circumstances and is fundamental […]

Universal Bound on Effective Central Charge and Its Saturation

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Andreas Karch, Yuya Kusuki, Hirosi Ooguri, Hao-Yu Sun, Mianqi Wang | Summary: The effective central charge (denoted by $c_{text{eff}}$) is a measure of entanglement through a conformal interface, while the transmission coefficient (encoded in the coefficient $c_{LR}$ of the two-point function of the energy-momentum tensor across the […]
