Kavli Affiliate: Paolo Privitera | First 5 Authors: Shunsuke Sakurai, Justin Albury, Jose Bellido, Fraser Bradfield, Ladislav Chytka | Summary: Ultra-high energy cosmic rays (UHECRs), whose energy are beyond $10^{18}~mathrm{eV}$, are the most energetic particles we have ever detected. The latest results seem to indicate a heavier composition at the highest energies, complicating the search […]

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Clarke J. Esmerian, Nickolay Y. Gnedin, , , | Summary: We model the interstellar dust content of the reionization era with a suite of cosmological, fluid-dynamical simulations of galaxies with stellar masses ranging from $sim 10^5 – 10^9 M_{odot}$ in the first $1.2$ billion years of […]

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Evan N. Kirby, Alexander P. Ji, Mikhail Kovalev, , | Summary: Whereas light element abundance variations are a hallmark of globular clusters, there is little evidence for variation in neutron-capture elements. A significant exception is M15, which shows a star-to-star dispersion in neutron-capture abundances of at […]

Kavli Affiliate: Wayne Hu | First 5 Authors: Jose María Ezquiaga, Wayne Hu, Rico K. L. Lo, , | Summary: Strongly lensed gravitational waves (GWs) from binary coalescence manifest as repeated chirps from the original merger. At the detectors, the phase of the lensed GWs and its arrival time differences will be consistent modulo a […]

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Amanda M. Farah, Maya Fishbach, Daniel E. Holz, , | Summary: When modeling the population of merging binary black holes, analyses generally focus on characterizing the distribution of primary (i.e. more massive) black holes in the binary, while simplistic prescriptions are used for the distribution of […]

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Wendy L. Freedman, Barry F. Madore, , , | Summary: Cepheids have been the cornerstone of the extragalactic distance scale for a century. With high-quality data, these luminous supergiants exhibit a small dispersion in their Leavitt (period-luminosity) relation, particularly at longer wavelengths, and few methods rival […]

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Syed A. Uddin, Christopher R. Burns, Mark M. Phillips, Nicholas B. Suntzeff, Wendy L. Freedman | Summary: We present an analysis of Type Ia Supernovae (SNe~Ia) from both the Carnegie Supernova Project~I (CSP-I) and II (CSP-II), and extend the Hubble diagram from the optical to the […]
