Prospects for the detection of the Diffuse Supernova Neutrino Background with the experiments SK-Gd and JUNO

Posted by dbos January 30, 2022Tokyo

Kavli Affiliate: Mark Vagins | First 5 Authors: Yu-Feng Li, Mark Vagins, Michael Wurm, , | Summary: The advent of gadolinium-loaded Super-Kamiokande (SK-Gd) and of the soon-to-start JUNO liquid scintillator detector marks a substantial improvement in the global sensitivity for the Diffuse Supernova Neutrino Background (DSNB). The present article reviews the detector properties most relevant […]

NEID Rossiter-McLaughlin Measurement of TOI-1268b: A Young Warm Saturn Aligned with Its Cool Host Star

Posted by klaurent January 30, 2022MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Jiayin Dong, Chelsea X. Huang, George Zhou, Rebekah I. Dawson, Gudmundur K. Stefánsson | Summary: Close-in gas giants present a surprising range of stellar obliquity, the angle between a planet’s orbital axis and its host star’s spin axis. It is unclear whether the obliquities reflect the planets’ […]

TransBTSV2: Towards Better and More Efficient Volumetric Segmentation of Medical Images

Posted by klaurent January 30, 2022Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jiangyun Li, Wenxuan Wang, Chen Chen, Tianxiang Zhang, Sen Zha | Summary: Transformer, benefiting from global (long-range) information modeling using self-attention mechanism, has been successful in natural language processing and computer vision recently. Convolutional Neural Networks, capable of capturing local features, are difficult to model explicit long-distance […]

E/B mode decomposition of HSC-Y1 cosmic shear using COSEBIs: cosmological constraints and comparison with other two-point statistics

Posted by klaurent January 30, 2022Tokyo

Kavli Affiliate: Chiaki Hikage | First 5 Authors: Takashi Hamana, Chiaki Hikage, Masamune Oguri, Masato Shirasaki, Surhud More | Summary: We perform a cosmic shear analysis of HSC survey first-year data (HSC-Y1) using Complete Orthogonal Sets of E/B-Integrals (COSEBIs) to derive cosmological constraints. We compute E/B-mode COSEBIs from cosmic shear two-point correlation functions measured on […]

Validation of 13 Hot and Potentially Terrestrial TESS Planets

Posted by klaurent January 29, 2022MIT

Kavli Affiliate: George R. Ricker | First 5 Authors: Steven Giacalone, Courtney D. Dressing, Christina Hedges, Veselin B. Kostov, Karen A. Collins | Summary: The James Webb Space Telescope (JWST) will be able to probe the atmospheres and surface properties of hot, terrestrial planets via emission spectroscopy. We identify 18 potentially terrestrial planet candidates detected […]

On the on-shell equivalence of general relativity and Holst theories with nonmetricity, torsion, and boundaries

Posted by klaurent January 28, 2022MIT

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Juan Margalef-Bentabol, Valle Varo, Eduardo J. S. Villaseñor, | Summary: We study a generalization of the Holst action where we admit nonmetricity and torsion in manifolds with timelike boundaries (both in the metric and tetrad formalism). We prove that its space of […]

Monitoring inner regions in the RY Tau jet

Posted by klaurent January 28, 2022MIT

Kavli Affiliate: Moritz Guenther | First 5 Authors: Taichi Uyama, Michihiro Takami, Gabriele Cugno, Vincent Deo, Olivier Guyon | Summary: We present multi-epoch observations of the RY~Tau jet for H$alpha$ and [ion{Fe}{2}] 1.644 micron~emission lines obtained with Subaru/SCExAO+VAMPIRES, Gemini/NIFS, and Keck/OSIRIS in 2019–2021. These data show a series of four knots within 1$arcsec$ consistent with […]

Using the Sun to Measure the Primary Beam Response of the Canadian Hydrogen Intensity Mapping Experiment

Posted by klaurent January 27, 2022MIT

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: CHIME Collaboration, Mandana Amiri, Kevin Bandura, Anja Boskovic, Jean-François Cliche | Summary: We present a beam pattern measurement of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) made using the Sun as a calibration source. As CHIME is a pure drift scan instrument, we rely on the seasonal […]
