Kavli Affiliate: Andrei Okounkov | 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 q-deformation of the quantum Langlands correspondence. This was done by realizing […]
Kavli Affiliate: Pau Amaro Seoane | Summary:Sagittarius A* exhibits daily energetic flares characterized by non-thermal emission in the infrared and X-ray bands. While the underlying accretion flow is a Radiatively Inefficient Accretion Flow (RIAF) peaking at radio frequencies, the mechanism powering these non-thermal transients remains debated. Stellar dynamics predict a population of faint brown dwarfs […]
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 Radiatively Inefficient […]
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 | 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 dataset and enable this measurement, we construct and analyze a realistic […]

Kavli Affiliate: Birgitta Whaley | 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 in the superfluid gyrometer and present a procedure for their experimental […]
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: Kenneth Miller | Authors: Tahereh Toosi and Kenneth D Miller | Summary: We understand how neurons respond selectively to patterns in visual input to support object recognition; however, how these circuits support perceptual grouping, illusory percepts, and imagination is not understood. These perceptual experiences are thought to require combining what we have learned […]
