Kavli Affiliate: Richard Kessler | First 5 Authors: Ayan Mitra, Richard Kessler, Surhud More, Renee Hlozek, The LSST Dark Energy Science Collaboration | Summary: We perform a rigorous cosmology analysis on simulated type Ia supernovae (SN~Ia) and evaluate the improvement from including photometric host-galaxy redshifts compared to using only the "zspec" subset with spectroscopic redshifts […]

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, Duncan Rocha, Anastasia Sokolenko, , | Summary: We study a simple model of vector dark matter that couples to Standard Model particles via magnetic dipole interactions. In this scenario, the cosmological abundance arises through the freeze-in mechanism and depends on the dipole coupling, the vector […]

Kavli Affiliate: Albert Stebbins | First 5 Authors: Zijie Yu, Furen Deng, Shijie Sun, Chenhui Niu, Jixia Li | Summary: The Tianlai Dish Pathfinder array is a radio interferometer array consisting of 16 six meter dish antennas. The original digital backend integration time is at the seconds level, designed for HI intensity mapping experiment. A […]

Kavli Affiliate: Emil Martinec | First 5 Authors: Daniel Harlow, Shamit Kachru, Juan Maldacena, Ibou Bah, Mike Blake | Summary: We give an overview of the field of quantum gravity, string theory and black holes summarizing various white papers in this subject that were submitted as part of the Snowmass process. | Search Query: ArXiv […]

Kavli Affiliate: Abigail Vieregg | First 5 Authors: Peter Gorham, James Anderson, Pietro Bernasconi, Supriya Chakrabarti, T. Gregory Guzik | Summary: From 2018 to 2020, the Scientific Balloon Roadmap Program Analysis Group (Balloon Roadmap PAG) served as an community-based, interdisciplinary forum for soliciting and coordinating community analysis and input in support of the NASA Scientific […]

Kavli Affiliate: Marcela Carena | First 5 Authors: Henning Bahl, Marcela Carena, Nina M. Coyle, Aurora Ireland, Carlos E. M. Wagner | Summary: Two Higgs doublet models (2HDM) provide the low energy effective field theory (EFT) description in many well motivated extensions of the Standard Model. It is therefore relevant to study their properties, as […]

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Diksha Garg, Sameer Patel, Mary Hall Reno, Alexander Ruestle, Yosui Akaike | Summary: Ultra-high-energy neutrinos serve as messengers of some of the highest energy astrophysical environments. Given that neutrinos are neutral and only interact via weak interactions, neutrinos can emerge from sources, traverse astronomical distances, and […]

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Hanjue Zhu, Nickolay Y. Gnedin, , , | Summary: Baryons both increase halo concentration through adiabatic contraction and expel mass through feedback processes. However, it is not well understood how the radiation fields prevalent during the epoch of reionization affect the evolution of concentration in dark […]
