Kavli Affiliate: Anna Frebel | First 5 Authors: Henrique Reggiani, Alexander P. Ji, Kevin C. Schlaufman, Anna Frebel, Lina Necib | Summary: Little is known about the origin of the fastest stars in the Galaxy. Our understanding of the Milky Way and surrounding dwarf galaxies chemical evolution history allows us to use the chemical composition […]
Kavli Affiliate: Jing Wang | First 5 Authors: Quecheng Qiu, Shunyi Yao, Jing Wang, Jun Ma, Guangda Chen | Summary: Existing navigation policies for autonomous robots tend to focus on collision avoidance while ignoring human-robot interactions in social life. For instance, robots can pass along the corridor safer and easier if pedestrians notice them. Sounds […]
Kavli Affiliate: Dale Li | First 5 Authors: Thomas Cecil, Clarence L. Chang, Shannon M. Duff, Dale Li, Rupak Mahapatra | Summary: Superconducting sensors are a key enabling technology for many HEP experiments with advances in sensor capabilities leading directly to expanded science reach. The unique materials and processes required for the fabrication of these […]

Kavli Affiliate: Feng Yuan | First 5 Authors: Shuo Li, Shuo Han, Shaohua Yan, Yi Cui, Le Wang | Summary: We performed high-pressure transport studies on the flat-band Kagome compounds, Pd$_3$P$_2$(S$_{1-x}$Se$_x$)$_8$ ($x$ = 0, 0.25), with a diamond anvil cell. For both compounds, the resistivity exhibits an insulating behavior with pressure up to 17 GPa. […]
Kavli Affiliate: Jia Liu | First 5 Authors: Vanessa Böhm, Jia Liu, , , | Summary: We study the impact of the COVID-19 pandemic on astronomy using public records of astronomical publications. We show that COVID-19 has had both positive and negative impacts on research in astronomy. We find that the overall output of the […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Haojie Hu, Kohei Inayoshi, Zoltán Haiman, Eliot Quataert, Rolf Kuiper | Summary: We study the long-term evolution of the global structure of axisymmetric accretion flows onto a black hole (BH) at rates substantially higher than the Eddington value ($dot{M}_{rm Edd}$), performing two-dimensional hydrodynamical simulations with and without […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aneesh Sivasankaran, Laura Blecha, Paul Torrey, Luke Zoltan Kelley, Aklant Bhowmick | Summary: We study gas inflows onto supermassive black holes using hydrodynamics simulations of isolated galaxies and idealized galaxy mergers with an explicit, multiphase interstellar medium (ISM). Our simulations use the recently developed ISM and stellar […]
Kavli Affiliate: Robert M. Wald | First 5 Authors: Kartik Prabhu, Gautam Satishchandran, Robert M. Wald, , | Summary: Infrared (IR) divergences arise in scattering theory with massless fields and are manifestations of the memory effect. There is nothing singular about states with memory, but they do not lie in the standard Fock space. IR […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Masahito Yamazaki, , , , | Summary: The goal of this short article is to summarize some of the recent developments in the quiver Yangians and crystal meltings. This article is based on a lecture delivered by the author at International Congress on Mathematical Physics (ICMP), Geneva, […]
