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: 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 […]
Kavli Affiliate: Michael Crisler | First 5 Authors: Liron Barak, Itay M. Bloch, Mariano Cababie, Gustavo Cancelo, Luke Chaplinsky | Summary: We present the first direct-detection search for eV-to-GeV dark matter using a new ~2-gram high-resistivity Skipper-CCD from a dedicated fabrication batch that was optimized for dark-matter searches. Using 24 days of data acquired in […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Shuang Du, Weihua Wang, Xuhao Wu, Renxin Xu, | Summary: We propose a geometrical explanation for periodically and nonperiodically repeating fast radio bursts (FRBs) under neutron star (NS)-companion systems. We suggest a constant critical binary separation, $r_{rm c}$, within which the interaction between the NS and companion […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Akio Kawasaki, Alexander Fieguth, Nadav Priel, Charles P. Blakemore, Denzal Martin | Summary: A high sensitivity force sensor based on dielectric microspheres in vacuum, optically trapped by a single, upward-propagating laser beam, is described. Off-axis parabolic mirrors are used both to focus the 1064~nm trapping beam and […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Karthik Ramanathan, Noah Kurinsky, , , | Summary: The development of single charge resolving, macroscopic silicon detectors has opened a window into rare processes at the O(eV) scale. In order to reconstruct the energy of a given event, or model the charge signal obtained for a given […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: BaBar Collaboration, J. P. Lees, V. Poireau, V. Tisserand, E. Grauges | Summary: We present a search for seven lepton-flavor-violating neutral charm decays of the type $D^{0}rightarrow X^{0} e^{pm} mu^{mp}$, where $X^{0}$ represents a $pi^{0}$, $K^{0}_{rm S}$, $bar{K^{*0}}$, $rho^{0}$, $phi$, $omega$, or $eta$ meson. The analysis […]
Kavli Affiliate: Gabor Furesz | First 5 Authors: Veselin B. Kostov, Jerome A. Orosz, Adina D. Feinstein, William F. Welsh, Wolf Cukier | Summary: We report the detection of the first circumbinary planet found by TESS. The target, a known eclipsing binary, was observed in sectors 1 through 12 at 30-minute cadence and in sectors […]
Kavli Affiliate: Christopher Burke | First 5 Authors: Ryan Cloutier, Joseph E. Rodriguez, Jonathan Irwin, David Charbonneau, Keivan G. Stassun | Summary: Small planets on close-in orbits tend to exhibit envelope mass fractions of either effectively zero or up to a few percent depending on their size and orbital period. Models of thermally-driven atmospheric mass […]
