Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: We present the first nonlinear lattice simulation of an axion field coupled to a U(1) gauge field during inflation. We use it to fully characterize the statistics of the primordial curvature perturbation {zeta}. We find high-order […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: If gauge fields are coupled to an axion field during inflation, they lead to unique observational signatures within the reach of next generation experiments. However, this system often shows strong backreaction effects, invalidating the standard perturbation […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Natasha Hurley-Walker, Timothy J. Galvin, Stefan W. Duchesne, Xiang Zhang, John Morgan | Summary: We describe a new low-frequency wideband radio survey of the southern sky. Observations covering 72 – 231 MHz and Declinations south of $+30^circ$ have been performed with the Murchison Widefield Array "extended" Phase […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Yutao Zhou, Chun Wang, Hongliang Yan, Yang Huang, Bo Zhang | Summary: The puzzle of Li-rich giant is still unsolved, contradicting the prediction of the standard stellar models. Although the exact evolutionary stages play a key role in the knowledge of Li-rich giants, a limited number of […]
Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Maximilian Huber, Yi Lin, Nicholas Dale, Renee Sailus, Sefaattin Tongay | Summary: Charge density waves (CDW) are states of broken symmetry with a periodic modulation of charge and lattice typically leading to the opening of a gap in the band structure. In the model CDW system 1T-TiSe$_2$ […]
Kavli Affiliate: Biao Huang | First 5 Authors: Zhiyinan Huang, Jinfeng Liu, Biao Huang, , | Summary: Water scarcity is an urgent issue to be resolved and improving irrigation water-use efficiency through closed-loop control is essential. The complex agro-hydrological system dynamics, however, often pose challenges in closed-loop control applications. In this work, we propose a […]
Kavli Affiliate: Itai Cohen | First 5 Authors: Jonathan Michel, Gabriel von Kessel, Thomas Wyse Jackson, Lawrence J. Bonassar, Itai Cohen | Summary: Many biological tissues feature a heterogeneous network of fibers whose tensile and bending rigidity contribute substantially to these tissues’ elastic properties. Rigidity percolation has emerged as a important paradigm for relating these […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Haojie Hu, Kohei Inayoshi, Zoltán Haiman, Wenxiu Li, Eliot Quataert | Summary: Observations of the most luminous quasars at high redshifts ($z > 6$) have revealed that the largest supermassive black holes (SMBHs) at those epochs tend to be substantially overmassive relative to their host galaxies compared […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Giulia Despali, Levi G. Walls, Simona Vegetti, Martin Sparre, Mark Vogelsberger | Summary: We study the effect of self-interacting dark matter (SIDM) and baryons on the shapes of early-type galaxies (ETGs) and their dark matter haloes, comparing them to the predictions of the standard cold dark matter […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: So Chigusa, Masahito Yamazaki, , , | Summary: We consider dark sector scenarios where dark matter is accompanied by a dark photon and multiple-flavor dark fermions charged under the dark gauge group. We study quantum interference effects in dark sector jets, where multiple dark photons are emitted […]
