Kavli Affiliate: Andrei Okounkov | First 5 Authors: Andrei Okounkov, , , , | Summary: We revisit the construction of stable envelopes in equivariant elliptic cohomology [arXiv:1604.00423] and give a direct inductive proof of their existence and uniqueness in a rather general situation. We also discuss the specialization of this construction to equivariant K-theory. | […]
Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Wenlong Yuan, Michael M. Fausnaugh, Samantha L. Hoffmann, Lucas M. Macri, Bradley M. Peterson | Summary: We derive a distance of $15.8pm0.4$ Mpc to the archetypical Seyfert 1 galaxy NGC 4151 based on the near-infrared Cepheid Period-Luminosity relation and new Hubble Space Telescope multiband imaging. This […]
Kavli Affiliate: Harry A. Atwater | First 5 Authors: Pankaj K. Jha, Hamidreza Akbari, Yonghwi Kim, Souvik Biswas, Harry A. Atwater | Summary: Color centers in hexagonal boron nitride (hBN) have emerged as promising candidates for single-photon emitters (SPEs) due to their bright emission characteristics at room temperature. In contrast to mono- and few-layered hBN, […]
Kavli Affiliate: James Chiang | First 5 Authors: James Chiang, , , , | Summary: Smart contracting protocols promise to regulate the transfer of cryptocurrency amongst participants in a trustless manner. A safe smart contract implementation should ensure that each participant can always append a contract transaction to the blockchain in order move the contract […]
Kavli Affiliate: Katia Bertoldi | First 5 Authors: Lishuai Jin, Antonio Elia Forte, Bolei Deng, Ahmad Rafsanjani, Katia Bertoldi | Summary: Kirigami, the Japanese art of paper cutting, has recently enabled the design of stretchable mechanical metamaterials that can be easily realized by embedding arrays of periodic cuts into an elastic sheet. Here, we exploit […]
Kavli Affiliate: David Spergel | First 5 Authors: Sigurd Naess, Simone Aiola, Jason E. Austermann, Nick Battaglia, James A. Beall | Summary: This paper presents a maximum-likelihood algorithm for combining sky maps with disparate sky coverage, angular resolution and spatially varying anisotropic noise into a single map of the sky. We use this to merge […]

Ade, Simone Aiola, David Alonso —- Summary: We present the temperature and polarization angular power spectra of the CMB measured by the Atacama Cosmology Telescope (ACT) from 5400 deg$^2$ […]
Kavli Affiliate: Shawn Henderson | First 5 Authors: Simone Aiola, Erminia Calabrese, Loïc Maurin, Sigurd Naess, Benjamin L. Schmitt | Summary: We present new arcminute-resolution maps of the Cosmic Microwave Background temperature and polarization anisotropy from the Atacama Cosmology Telescope, using data taken from 2013-2016 at 98 and 150 GHz. The maps cover more than […]
Kavli Affiliate: David Spergel | First 5 Authors: Daniel Tamayo, Miles Cranmer, Samuel Hadden, Hanno Rein, Peter Battaglia | Summary: We combine analytical understanding of resonant dynamics in two-planet systems with machine learning techniques to train a model capable of robustly classifying stability in compact multi-planet systems over long timescales of $10^9$ orbits. Our Stability […]
Kavli Affiliate: Eric D. Miller | First 5 Authors: Hitomi Suzuki, Hiroya Yamaguchi, Manabu Ishida, Hiroyuki Uchida, Paul P. Plucinsky | Summary: We present XMM-Newton observations of N132D, the X-ray brightest supernova remnant (SNR) in the Large Magellanic Cloud (LMC), using the Reflection Grating Spectrometer (RGS) that enables high-resolution spectroscopy in the soft X-ray band.
