Kavli Affiliate: Rainer Spurzem | First 5 Authors: Katja Stock, Maxwell X. Cai, Rainer Spurzem, M. B. N. Kouwenhoven, Simon Portegies Zwart | Summary: Despite the discovery of thousands of exoplanets in recent years, the number of known exoplanets in star clusters remains tiny. This may be a consequence of close stellar encounters perturbing the […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Sophie Koudmani, Nicholas A. Henden, Debora Sijacki, , | Summary: Contrary to the standard lore, there is mounting observational evidence that feedback from active galactic nuclei (AGN) may also play a role at the low-mass end of the galaxy population. We investigate this using the cosmological simulation […]
Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Alexander Braverman, Michael Finkelberg, Hiraku Nakajima, , | Summary: We deduce the Kazhdan-Lusztig conjecture on the multiplicities of simple modules over a simple complex Lie algebra in Verma modules in category O from the equivariant geometric Satake correspondence and the analysis of torus fixed points in zastava […]

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: 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: 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 […]
Kavli Affiliate: Dale Li Authors: Steve K. Choi, Matthew Hasselfield, Shuay-Pwu Patty Ho, Brian Koopman, Marius Lungu, Maximilian H. Abitbol, Graeme E. Addison, Peter A. R. 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 […]
