Uniform automated analysis of Sdiff splitting due to lowermost mantle anisotropy: Caveats and curated global dataset

Summary Seismic anisotropy, the dependence of seismic wave speeds on the direction of propagation and/or polarization, places crucial constraints on deformation and convective flow in the lowermost mantle (the D″ layer). Shear waves that diffract along the core-mantle boundary (C...

SN 2024iss: A Multiwavelength Exposé of a Type IIb Supernova with an Early-time Ultraviolet Spectrum and Shock-breakout Constraints

Abstract We present multiwavelength observations and analysis of SN 2024iss, a Type IIb supernova (SN IIb) located at ∼14 Mpc. The first Zwicky Transient Facility detection of SN 2024iss is ∼40 minutes after first light (one of the earliest detections of a SN IIb to date) and a H...

Money and muscle: corporate political power and government subsidies

Political power is one of the most extensively discussed issues in political economy, although prior researchers provide few metrics for its estimation. This study introduces a new set of corporate political power measures using the political power of individual legislators and f...
