Constraints on conformal ultralight dark matter couplings from the European Pulsar Timing Array

Kavli Affiliate: Lijing Shao | First 5 Authors: Clemente Smarra, Adrien Kuntz, Enrico Barausse, Boris Goncharov, Diana López Nacir | Summary: Millisecond pulsars are extremely precise celestial clocks: as they rotate, the beamed radio waves emitted along the axis of their magnetic field can be detected with radio telescopes, which allows for tracking subtle changes […]

The Simons Observatory: Combining cross-spectral foreground cleaning with multitracer $B$-mode delensing for improved constraints on inflation

Kavli Affiliate: Blake Sherwin | First 5 Authors: Emilie Hertig, Kevin Wolz, Toshiya Namikawa, Antón Baleato Lizancos, Susanna Azzoni | Summary: The Simons Observatory (SO), due to start full science operations in early 2025, aims to set tight constraints on inflationary physics by inferring the tensor-to-scalar ratio $r$ from measurements of CMB polarization $B$-modes. Its […]

The Atacama Cosmology Telescope: Reionization kSZ trispectrum methodology and limits

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Niall MacCrann, Frank J. Qu, Toshiya Namikawa, Boris Bolliet, Hongbo Cai | Summary: Patchy reionization generates kinematic Sunyaev-Zeldovich (kSZ) anisotropies in the cosmic microwave background (CMB). Large-scale velocity perturbations along the line of sight modulate the small-scale kSZ power spectrum, leading to a trispectrum (or four-point function) […]

Coordination and persistence of aggressive visual communication in Siamese fighting fish

Kavli Affiliate: Liam Paninski | Authors: Claire P. Everett, Amy L. Norovich, Jessica E. Burke, Matthew R Whiteway, Pei-Yin Shih, Yuyang Zhu, Liam Paninski and Andres Bendesky | Summary: Animals coordinate their behavior with each other during both cooperative and agonistic social interactions. Such coordination often adopts the form of “turn taking”, in which the […]

Distinct anatomical and functional corticospinal inputs innervate different spinal neuron types

Kavli Affiliate: Liam Paninski | Authors: Samaher Fageiry, Claire L Warriner, Jackson Loper, Liam Paninski, Thomas Reardon, Thomas M. Jessell, Rui M. Costa and Andrew Miri | Summary: The corticospinal tract exerts its influence on movement through spinal neurons, which can be divided into types that exhibit distinct functions. However, it remains unknown whether these […]

Microscopic origin of twist-dependent electron transfer rate in bilayer graphene

Kavli Affiliate: David T. Limmer | First 5 Authors: Leonardo Coello Escalante, David T. Limmer, , , | Summary: Using molecular simulation and continuum dielectric theory, we consider how electrochemical kinetics are modulated as a function of twist angle in bilayer graphene electrodes. By establishing an effective connection between twist angle and the screening length […]
