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: 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, […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Sebastian Baum, Francesco Capozzi, Shunsaku Horiuchi, , | Summary: Measuring core-collapse supernova neutrinos, both from individual supernovae within the Milky Way and from past core collapses throughout the Universe (the diffuse supernova neutrino background, or DSNB), is one of the main goals of current and next generation […]
Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Xiao-Ping Wang, Ke-Pan Xie, , | Summary: The weakly interacting massive particles (WIMPs) have been the most popular particle dark matter (DM) candidate for the last several decades, and it is well known that WIMP can be probed via the direct, indirect and collider experiments. […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Kai Murai, , , | Summary: The recent observation of $^4$He implies that our universe has a large lepton asymmetry. We consider the Affleck-Dine (AD) mechanism for lepton number generation. In the AD mechanism, non-topological solitons called L-balls are produced, and the generated lepton number […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Akinori Matsumoto, Masami Ouchi, Kimihiko Nakajima, Masahiro Kawasaki, Kai Murai | Summary: The primordial He abundance $Y_P$ is a powerful probe of cosmology. Currently, $Y_P$ is best determined by observations of metal-poor galaxies, while there are only a few known local extremely metal-poor ($<0.1 Z_odot$) galaxies (EMPGs) […]

Kavli Affiliate: David Spergel | First 5 Authors: Kevork Abazajian, Arwa Abdulghafour, Graeme E. Addison, Peter Adshead, Zeeshan Ahmed | Summary: This Snowmass 2021 White Paper describes the Cosmic Microwave Background Stage 4 project CMB-S4, which is designed to cross critical thresholds in our understanding of the origin and evolution of the Universe, from the […]
Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Alexander Aryshev, Ties Behnke, Mikael Berggren, James Brau, Nathaniel Craig | Summary: The International Linear Collider (ILC) is on the table now as a new global energy-frontier accelerator laboratory taking data in the 2030s. The ILC addresses key questions for our current understanding of particle physics. It […]
