Performance of a Kinetic Inductance Phonon-Mediated Detector at the NEXUS Cryogenic Facility

Posted by klaurent Stanford

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Dylan J Temples, Osmond Wen, Karthik Ramanathan, Taylor Aralis, Yen-Yung Chang | Summary: Microcalorimeters that leverage microwave kinetic inductance detectors to read out phonon signals in the particle-absorbing target, referred to as kinetic inductance phonon-mediated (KIPM) detectors, offer an attractive detector architecture to probe dark matter (DM) […]

Understanding spectral artefacts in SKA-LOW 21-cm cosmology experiments: the impact of cable reflections

Posted by dbos Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Oscar Sage David O’Hara, Fred Dulwich, Eloy de Lera Acedo, Jiten Dhandha, Thomas Gessey-Jones | Summary: The Cosmic Dawn marks the first star formations and preceded the Epoch-of-Reionization, when the Universe underwent a fundamental transformation propelled by the radiation from these first stars and galaxies. Interferometric 21-cm […]

Measurement of $CP$ asymmetries in $B^0toη’K^0_s$ decays at Belle II

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: We describe a measurement of charge-parity ($CP$) violation asymmetries in $B^0toeta’K^0_S$ decays using Belle II data. We consider $eta’toeta(togammagamma)pi^+pi^-$ and $eta’torho(topi^+pi^-)gamma$ decays. The data were collected at the SuperKEKB asymmetric-energy $e^+e^-$ collider between the […]

Introducing the BRAHMA simulation suite: Signatures of low mass black hole seeding models in cosmological simulations

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K. Bhowmick, Laura Blecha, Paul Torrey, Luke Zoltan Kelley, Rainer Weinberger | Summary: The first "seeds" of supermassive black holes (BH) can range from $sim10^2-10^6~M_{odot}$. However, the lowest mass seeds ($lesssim10^3 M_{odot}$) are inaccessible to most cosmological simulations due to resolution limitations. We present our new […]

The TESS-Keck Survey. XIX. A Warm Transiting Sub-Saturn Mass Planet and a non-Transiting Saturn Mass Planet Orbiting a Solar Analog

Posted by dbos MIT

Kavli Affiliate: George R. Ricker | First 5 Authors: Michelle L. Hill, Stephen R. Kane, Paul A. Dalba, Mason MacDougall, Tara Fetherolf | Summary: The Transiting Exoplanet Survey Satellite (TESS) continues to dramatically increase the number of known transiting exoplanets, and is optimal for monitoring bright stars amenable to radial velocity (RV) and atmospheric follow-up […]

Dramatic rebrightening of the type-changing stripped-envelope supernova SN 2023aew

Posted by dbos MIT

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Yashvi Sharma, Jesper Sollerman, Shrinivas R. Kulkarni, Takashi J. Moriya, Steve Schulze | Summary: Multi-peaked supernovae with precursors, dramatic light-curve rebrightenings, and spectral transformation are rare, but are being discovered in increasing numbers by modern night-sky transient surveys like the Zwicky Transient Facility (ZTF). Here, we present […]
