Kavli Affiliate: Stavros Katsanevas | First 5 Authors: Michele Punturo, David Reitze, Peter Couvares, Stavros Katsanevas, Takaaki Kajita | Summary: Planning for the development of a 3rd generation global gravitational-wave detector array is a multifaceted and complex effort that will necessarily need a high level of community input. Interfacing to extant and new stakeholders in […]
Kavli Affiliate: Takaaki Kajita | First 5 Authors: Peter Couvares, Ian Bird, Ed Porter, Stefano Bagnasco, Michele Punturo | Summary: Cyber infrastructure will be a critical consideration in the development of next generation gravitational-wave detectors. The demand for data analysis computing in the 3G era will be driven by the high number of detections as […]
Kavli Affiliate: Takaaki Kajita | First 5 Authors: David Reitze, Michele Punturo, Peter Couvares, Stavros Katsanevas, Takaaki Kajita | Summary: The first direct detection of gravitational waves emitted from a pair of merging black holes in 2015 has been heralded as one of most significant scientific breakthroughs in physics and astronomy of the 21st century. […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Zhi Chen, Alexander Ogren, Chiara Daraio, L. Catherine Brinson, Cynthia Rudin | Summary: Metamaterials are composite materials with engineered geometrical micro- and meso-structures that can lead to uncommon physical properties, like negative Poisson’s ratio or ultra-low shear resistance. Periodic metamaterials are composed of repeating unit-cells, and geometrical […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Brian Henning, Xiaochuan Lu, Tom Melia, Hitoshi Murayama, | Summary: We discuss anomalies associated with outer automorphisms in gauge theories based on classical groups, namely charge conjugations for $SU(N)$ and parities for $SO(2r)$. We emphasize the inequivalence between two versions of charge conjugation for $SU(N)$ symmetries, and […]
Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Tom Melia, Sridip Pal, , | Summary: We give a proof that in any weakly coupled quantum field theory with a finite group global symmetry $mathrm{G}$, on a compact spatial manifold, at sufficiently high energy, the density of states $rho_alpha(E)$ for each irreducible representation $alpha$ […]
Kavli Affiliate: Thomas M. Crawford | First 5 Authors: Michael Janssen, Heino Falcke, Matthias Kadler, Eduardo Ros, Maciek Wielgus | Summary: Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of extragalactic radio jets, down to $10-100$ gravitational radii ($r_g=GM/c^2$) scales in […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Hironao Miyatake, Sunao Sugiyama, Masahiro Takada, Takahiro Nishimichi, Masato Shirasaki | Summary: We present high-fidelity cosmology results from a blinded joint analysis of galaxy-galaxy weak lensing ($Delta!Sigma$) and projected galaxy clustering ($w_{rm p}$) measured from the Hyper Suprime-Cam Year-1 (HSC-Y1) data and spectroscopic Sloan Digital Sky Survey […]
Kavli Affiliate: John E. Carlstrom | First 5 Authors: Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel, Lia Medeiros, Sean T. Dougall | Summary: The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center of the M87 galaxy, […]
Kavli Affiliate: Jia Liu | First 5 Authors: Jinhui Guo, Yuxuan He, Jia Liu, Xiao-Ping Wang, | Summary: The coannihilation mechanism is a well-motivated alternative to the simple thermal freeze-out mechanism, where the dark matter relic density can be obtained through the coannihilation with a partner particle of similar mass with dark matter. When the […]
