Nearest Neighbor distributions: new statistical measures for cosmological clustering

Kavli Affiliate: Tom Abel | First 5 Authors: Arka Banerjee, Tom Abel, , , | Summary: The use of summary statistics beyond the two-point correlation function to analyze the non-Gaussian clustering on small scales is an active field of research in cosmology. In this paper, we explore a set of new summary statistics — the […]

Revisiting AGN as the Source of IceCube’s Diffuse Neutrino Flux

Kavli Affiliate: Abigail Vieregg | First 5 Authors: Daniel Smith, Dan Hooper, Abigail Vieregg, , | Summary: The origin of the astrophysical neutrino flux reported by the IceCube Collaboration remains an open question. In this study, we use three years of publicly available IceCube data to search for evidence of neutrino emission from the blazars […]

Planetary Systems in a Star Cluster II: intermediate-mass black holes and planetary systems

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Francesco Flammini Dotti, M. B. N. Kouwenhoven, Qi Shu, Wei Hao, Rainer Spurzem | Summary: Most stars form in dense stellar environments. It is speculated that some dense star clusters may host intermediate-mass black holes (IMBHs), which may have formed from runaway collisions between high-mass stars, or […]

On the survival of resonant and non-resonant planetary systems in star clusters

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 […]

A little FABLE: exploring AGN feedback in dwarf galaxies with cosmological simulations

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 […]

Kazhdan-Lusztig conjecture via Zastava spaces

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 […]

Inductive construction of stable envelopes

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. | […]

The Cepheid Distance to the Seyfert 1 Galaxy NGC 4151

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 […]

Bitcoin Trace-Net: Formal Contract Verification at Signing Time

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 […]
