Gamma-ray Bursts as Distance Indicators by a Statistical Learning Approach

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Maria Giovanna Dainotti, Aditya Narendra, Agnieszka Pollo, Vahe Petrosian, Malgorzata Bogdan | Summary: Gamma-ray bursts (GRBs) can be probes of the early universe, but currently, only 26% of GRBs observed by the Neil Gehrels Swift Observatory GRBs have known redshifts ($z$) due to observational limitations. To address […]

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

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

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

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

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

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 […]
