Kavli Affiliate: Erin A. Kara | First 5 Authors: Hermine Landt, Hermine Landt, , , | Summary: The AGN Space Telescope and Optical Reverberation Mapping 2 (STORM 2) campaign targeted Mrk 817 with intensive multi-wavelength monitoring and found its soft X-ray emission to be strongly absorbed. We present results from 157 near-IR spectra with an […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, Belle II Collaboration, , , | Summary: We measure the time- and phase-space-integrated $CP$ asymmetry $A_CP$ in $D^0topi^+pi^-pi^0$ decays reconstructed in $e^+e^-to cbar c$ events collected by the Belle II experiment from 2019 to 2022. This sample corresponds to an integrated luminosity of 428 […]
Kavli Affiliate: Andrei Okounkov | First 5 Authors: Mina Aganagic, Mina Aganagic, , , | Summary: In our paper arXiv:1701.03146 we established, for every simply-laced Lie algebra g, a canonical isomorphism between the spaces of deformed conformal blocks of the deformed W-algebra and the quantum affine algebra corresponding to g, which we view as a […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Pau Amaro Seoane, , , | Summary: Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, exhibits daily energetic flares characterized by non-thermal emission in the infrared and X-ray bands. While the underlying accretion flow is a […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Tingfang Su, Tingfang Su, , , | Summary: The role of active galactic nuclei (AGN) feedback in dwarf galaxies remains poorly understood, with conventional wisdom suggesting it primarily suppresses star formation. Using high-resolution MACER3D simulations that directly resolve the Bondi radius, we demonstrate that AGN feedback can […]
Kavli Affiliate: Aaron Roodman | First 5 Authors: Padmavathi Venkatraman, Padmavathi Venkatraman, , , | Summary: Strong gravitational lensing of active galactic nuclei (AGN) enables measurements of cosmological parameters through time-delay cosmography (TDC). With data from the upcoming LSST survey, we anticipate using a sample of O(1000) lensed AGN for TDC. To prepare for this […]
Kavli Affiliate: Birgitta Whaley | First 5 Authors: Kai-Isaak Ellers, Kai-Isaak Ellers, , , | Summary: We propose a laboratory-scale experiment to locally measure the general relativistic frame-dragging effect on Earth using the macroscopic quantum properties of a novel superfluid $^4$He single Josephson junction gyrometer. We derive the frame-dragging and related geodetic and Thomas effects […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle, , , | Summary: Using data samples of 988.4 fb$^-1$ and 427.9 fb$^-1$ collected with the Belle and Belle II detectors, we present a study of the singly Cabibbo-suppressed decays $Xi_c^0 to Lambda eta$, $Lambda eta’$, and $Lambda pi^0$. We observe the decay $Xi_c^0 to […]
Kavli Affiliate: Jia Liu | First 5 Authors: Rundong Fang, Rundong Fang, , , | Summary: We investigate long-range, purely leptophilic axial-vector interactions mediated by a light gauge boson $A’$ that couples to charged leptons and, by weak symmetry, to left-handed neutrinos. We analyze two realizations, a minimal effective model with muon-only couplings and an […]
Kavli Affiliate: Michael Wimmer | First 5 Authors: William Samuelson, William Samuelson, , , | Summary: Protecting qubits from perturbations is a central challenge in quantum computing. Topological superconductors with separated Majorana bound states (MBSs) provide a strong form of protection that only depends on the locality of perturbations. While the link between MBS separation, […]
