Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Chang-Tse Hsieh, Yuji Tachikawa, Kazuya Yonekura, , | Summary: Chiral and non-chiral $p$-form gauge fields have gravitational anomalies and anomalies of Green-Schwarz type. This means that they are most naturally realized as the boundary modes of bulk topological phases in one higher dimensions. We give a systematic […]
Kavli Affiliate: Takaaki Kajita | First 5 Authors: Tomohiro Yamada, Takayuki Tomaru, Toshikazu Suzuki, Takafumi Ushiba, Nobuhiro Kimura | Summary: We developed a soft and high thermal conductive heat link for cryogenic applications. The measured maximum thermal conductivity was approximately 18500 W/m/K at 10 K. This spring constant was 1/43 of that of a single […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: Chelsea X. Huang, Samuel N. Quinn, Andrew Vanderburg, Juliette Becker, Joseph E. Rodriguez | Summary: Hot Jupiters are rarely accompanied by other planets within a factor of a few in orbital distance. Previously, only two such systems have been found. Here, we report the discovery of […]
Kavli Affiliate: Aaron Roodman | First 5 Authors: Hengxiao Guo, Colin J. Burke, Xin Liu, Kedar A. Phadke, Kaiwen Zhang | Summary: We report the identification of a low-mass AGN, DES J0218$-$0430, in a redshift $z = 0.823$ galaxy in the Dark Energy Survey (DES) Supernova field. We select DES J0218$-$0430 as an AGN candidate […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: Paul A. Dalba, Arvind F. Gupta, Joseph E. Rodriguez, Diana Dragomir, Chelsea X. Huang | Summary: We report the detection of a Saturn-size exoplanet orbiting HD 332231 (TOI 1456) in light curves from the Transiting Exoplanet Survey Satellite (TESS). HD 332231, an F8 dwarf star with […]
Kavli Affiliate: Robert Cameron | First 5 Authors: Mayukh Panja, Robert Cameron, Sami K. Solanki, , | Summary: There are no direct spatially resolved observations of spots on stars other than the Sun and starspot properties are inferred indirectly through lightcurves and spectropolarimetric data. We present the first self-consistent 3D radiative MHD computations of starspots […]
Kavli Affiliate: Shawn Henderson | First 5 Authors: Mayuri Sathyanarayana Rao, Maximiliano Silva-Feaver, Aamir Ali, Kam Arnold, Peter Ashton | Summary: The Simons Observatory (SO) is an upcoming polarization-sensitive Cosmic Microwave Background (CMB) experiment on the Cerro Toco Plateau (Chile) with large overlap with other optical and infrared surveys (e.g., DESI, LSST, HSC). To enable […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Wei Li, Masahito Yamazaki, , , | Summary: We find a new infinite class of infinite-dimensional algebras acting on BPS states for non-compact toric Calabi-Yau threefolds. In Type IIA superstring compactification on a toric Calabi-Yau threefold, the D-branes wrapping holomorphic cycles represent the BPS states, and the […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Joshua S. Dillon, Max Lee, Zaki S. Ali, Aaron R. Parsons, Naomi Orosz | Summary: In 21 cm cosmology, precision calibration is key to the separation of the neutral hydrogen signal from very bright but spectrally-smooth astrophysical foregrounds. The Hydrogen Epoch of Reionization Array (HERA), an interferometer […]
Kavli Affiliate: David P. Huenemoerder | First 5 Authors: David P. Huenemoerder, Richard Ignace, Nathan A. Miller, Kenneth G. Gayley, Wolf-Rainer Hamann | Summary: We have obtained a very deep exposure (813 ks) of $zeta,$Puppis (O4 supergiant) with the Chandra/HETG Spectrometer. Here we report on analysis of the 1-9 r{A} region, especially well suited for […]
