Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Stephen F. King, Rishav Roshan, Xin Wang, Graham White, Masahito Yamazaki | Summary: We explore the phenomenological consequences of breaking discrete global symmetries in quantum gravity (QG). We extend a previous scenario where discrete global symmetries are responsible for scalar dark matter (DM) and domain walls (DWs), […]
Kavli Affiliate: Sven Herrmann | First 5 Authors: Jan Scheumann, Dennis Philipp, Sven Herrmann, Eva Hackmann, Benny Rievers | Summary: All experiments to date are in remarkable agreement with the predictions of Einstein’s theory of gravity, General Relativity. Besides the classical tests, involving light deflection, orbit precession, signal delay, and the gravitational redshift, modern technology […]
Kavli Affiliate: Erin Kara | First 5 Authors: Constanza Echiburú-Trujillo, Alexandra J. Tetarenko, Daryl Haggard, Thomas D. Russell, Karri I. I. Koljonen | Summary: Black hole X-ray binaries (BH XRBs) are ideal targets to study the connection between accretion inflow and jet outflow. Here we present quasi-simultaneous, multi-wavelength observations of the Galactic black hole system […]

Kavli Affiliate: Lijing Shao | First 5 Authors: Yiming Dong, Ziming Wang, Lijing Shao, , | Summary: Lorentz Invariance Violation (LIV) is posited as a possible relic effect of quantum gravity at low energy scales. The Standard-Model Extension provides an effective field-theoretic framework for examining possible deviations attributed to LIV. With the observations of the […]

The Standard-Model Extension provides an effective field-theoretic framework for examining possible deviations attributed to LV. With their high observational accuracy, pulsars […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Cari Cesarotti, Yonatan Kahn, Gordan Krnjaic, Duncan Rocha, Joshua Spitz | Summary: Accelerator-based experiments reliant on charged pion and kaon decays to produce muon-neutrino beams also deliver an associated powerful flux of muons. Therefore, these experiments can additionally be sensitive to light new particles that preferentially couple […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Zhilei Xu, Honggeun Kim, Jacqueline N. Hewitt, Kai-Feng Chen, Nicholas S. Kern | Summary: The key to detecting neutral hydrogen during the epoch of reionization (EoR) is to separate the cosmological signal from the dominating foreground radiation. We developed direct optimal mapping (Xu et al. 2022) […]

Kavli Affiliate: Ke Wang | First 5 Authors: Wei Ren, Konstantin Davydov, Ziyan Zhu, Jaden Ma, Kenji Watanabe | Summary: We fabricate a twisted trilayer graphene device with consecutive twist angles of 1.33 and 1.64 degrees, in which we electrostatically tune the electronic states from each of the two co-existing moir’e superlattices and the interactions […]
