Electrical spectroscopy of the spin-wave dispersion and bistability in gallium-doped yttrium iron garnet

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Joris J. Carmiggelt, Olaf C. Dreijer, Carsten Dubs, Oleksii Surzhenko, Toeno van der Sar | Summary: Yttrium iron garnet (YIG) is a magnetic insulator with record-low damping, allowing spin-wave transport over macroscopic distances. Doping YIG with gallium ions greatly reduces the demagnetizing field and introduces […]

Evaluating and Enhancing Candidate Clocking Systems for CHIME/FRB VLBI Outriggers

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Savannah Cary, Juan Mena-Parra, Calvin Leung, Kiyoshi Masui, J. F. Kaczmarek | Summary: As the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has become the leading instrument for detecting Fast Radio Bursts (FRBs), CHIME/FRB Outriggers will use very-long-baseline interferometry (VLBI) to localize FRBs with milliarcsecond precision. The CHIME […]

Directional Detection of Light Dark Matter in Superconductors

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Yonit Hochberg, Eric David Kramer, Noah Kurinsky, Benjamin V. Lehmann, | Summary: Superconducting detectors have been proposed as outstanding targets for the direct detection of light dark matter scattering at masses as low as a keV. We study the prospects for directional detection of dark matter in […]

The Atacama Cosmology Telescope: Constraints on Pre-Recombination Early Dark Energy

Kavli Affiliate: David N. Spergel | First 5 Authors: J. Colin Hill, Erminia Calabrese, Simone Aiola, Nicholas Battaglia, Boris Bolliet | Summary: The early dark energy (EDE) scenario aims to increase the value of the Hubble constant ($H_0$) inferred from cosmic microwave background (CMB) data over that found in $Lambda$CDM, via the introduction of a […]

The obliquity of HIP 67522 b: a 17 Myr old transiting hot Jupiter-sized planet

Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Alexis Heitzmann, George Zhou, Samuel N. Quinn, Stephen C. Marsden, Duncan Wright | Summary: HIP 67522 b is a 17 Myr old, close-in ($P_{orb} = 6.96$ d), Jupiter-sized ($R = 10,R_{oplus}$) transiting planet orbiting a Sun like star in the Sco-Cen OB association. We present our […]

Self-sealing complex oxide resonators

Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Martin Lee, Martin Robin, Ruben Guis, Ulderico Filippozzi, Dong Hoon Shin | Summary: Although 2D materials hold great potential for next-generation pressure sensors, recent studies revealed that gases permeate along the membrane-surface interface that is only weakly bound by van der Waals interactions, […]

The effect of active galactic nuclei on the cold interstellar medium in distant star-forming galaxies

Kavli Affiliate: John D. Silverman | First 5 Authors: Francesco Valentino, Emanuele Daddi, Annagrazia Puglisi, Georgios E. Magdis, Vasily Kokorev | Summary: In the framework of a systematic ALMA study of IR-selected main-sequence and starburst galaxies at z~1-1.7 at typical ~1" resolution, we report on the effects of mid-IR- and X-ray-detected active galactic nuclei (AGN) […]

Reionization with Simba: How much does astrophysics matter in modeling cosmic reionization?

Kavli Affiliate: David N. Spergel | First 5 Authors: Sultan Hassan, Romeel DavĂ©, Matthew McQuinn, Rachel S. Somerville, Laura C. Keating | Summary: Traditional large-scale models of reionization usually employ simple deterministic relations between halo mass and luminosity to predict how reionization proceeds. We here examine the impact on modelling reionization of using more detailed […]
