Kavli Affiliate: Savdeep Sethi | First 5 Authors: T. Daniel Brennan, Christian Ferko, Emil Martinec, Savdeep Sethi, | Summary: We show that the $T overline{T}$ deformation of two-dimensional quantum field theory on $mathrm{AdS}_2$ is well-defined and solvable at the quantum level. Flow equations for the energy spectrum and partition function are derived in analogy with […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: John P. Ahlers, Marshall C. Johnson, Keivan G Stassun, Knicole D. Colon, Jason W. Barnes | Summary: KELT-9 b is an ultra hot Jupiter transiting a rapidly rotating, oblate early-A-type star in a polar orbit. We model the effect of rapid stellar rotation on KELT-9 b’s […]
Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Stefano Andriolo, Tzu-Chen Huang, Toshifumi Noumi, Hirosi Ooguri, Gary Shiu | Summary: The axionic weak gravity conjecture predicts the existence of instantons whose actions are less than their charges in appropriate units. We show that the conjecture is satisfied for the axion-dilaton-gravity system if we assume duality […]
Kavli Affiliate: Naoki Yasuda | First 5 Authors: Tian Qiu, Wenting Wang, Masahiro Takada, Naoki Yasuda, Željko Ivezić | Summary: We present proper motion measurements for more than $0.55$ million main-sequence stars, by comparing astrometric positions of matched stars between the multi-band imaging datasets from the Hyper Suprime-Cam (HSC) Survey and the SDSS Stripe 82. […]
Kavli Affiliate: Abigail Vieregg | First 5 Authors: Stephanie Wissel, Andrés Romero-Wolf, Harm Schoorlemmer, Washington R. Carvalho Jr., Jaime Alvarez-Muñiz | Summary: Tau neutrinos are expected to comprise roughly one third of both the astrophysical and cosmogenic neutrino flux, but currently the flavor ratio is poorly constrained and the expected flux at energies above $10^{17}$ […]
Kavli Affiliate: Anthony Lasenby | First 5 Authors: Kamran Javid, Will Handley, Mike Hobson, Anthony Lasenby, | Summary: We conduct a thorough analysis of the relationship between the out-of-sample performance and the Bayesian evidence (marginal likelihood) of Bayesian neural networks (BNNs), as well as looking at the performance of ensembles of BNNs, both using the […]
Kavli Affiliate: Carlos Bustamante | First 5 Authors: Daniel Mas Montserrat, Arvind Kumar, Carlos Bustamante, Alexander Ioannidis, | Summary: With declining sequencing costs a promising and affordable tool is emerging in cancer diagnostics: genomics. By using association studies, genomic variants that predispose patients to specific cancers can be identified, while by using tumor genomics cancer […]

Kavli Affiliate: Ralf K. Heilmann | First 5 Authors: Brandon D. Chalifoux, Ralf K. Heilmann, Herman L. Marshall, Mark L. Schattenburg, | Summary: Astronomical imaging with micro-arcsecond ($mu$as) angular resolution could enable breakthrough scientific discoveries. Previously-proposed $mu$as X-ray imager designs have been interferometers with limited effective collecting area. Here we describe X-ray telescopes achieving diffraction-limited […]
Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Tommaso Ghigna, Tomotake Matsumura, Guillaume Patanchon, Hirokazu Ishino, Masashi Hazumi | Summary: Current and future Cosmic Microwave Background (CMB) Radiation experiments are targeting the polarized $B$-mode signal. The small amplitude of this signal makes a successful measurement challenging for current technologies. Therefore, very accurate studies to mitigate […]
