Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Jeroen Homan, Joe Bright, Sara E. Motta, Diego Altamirano, Zaven Arzoumanian | Summary: We present Neutron Star Interior Composition Explorer X-ray and Arcminute Microkelvin Imager Large Array radio observations of a rapid hard-to-soft state transition in the black hole X-ray transient MAXI J1820+070. During the transition […]
Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yalong Cao, Yukinobu Toda, , , | Summary: The Gopakumar-Vafa type invariants on Calabi-Yau 4-folds (which are non-trivial only for genus zero and one) are defined by Klemm-Pandharipande from Gromov-Witten theory, and their integrality is conjectured. In a previous work of Cao-Maulik-Toda, $mathrm{DT}_4$ invariants with primary insertions […]
Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Chengying Bao, Boqiang Shen, Myoung-Gyun Suh, Heming Wang, Kemal Safak | Summary: Both the group velocity and phase velocity of two solitons can be synchronized by a Kerr-effect mediated interaction, causing what is known as soliton trapping. Trapping can occur when solitons travel through single-pass optical […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Noah Kurinsky, Daniel Baxter, Yonatan Kahn, Gordan Krnjaic, Peter Abbamonte | Summary: We respond to Robinson and Michaud’s (RM) comment (arXiv:2002.08893) on our recent preprint arXiv:2002.06937, in which we discuss recent excesses in low-threshold dark matter searches, and offer a potential unifying dark matter interpretation. We thank […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Philip Camayd-Muñoz, Conner Ballew, Gregory Roberts, Andrei Faraon, | Summary: Three-dimensional elements, with refractive index distribution structured at sub-wavelength scale, provide an expansive optical design space that can be harnessed for demonstrating multi-functional free-space optical devices. Here we present 3D dielectric elements, designed to be placed on […]
Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Jo Dunkley, Carlos Frenk, Ofer Lahav, Alice Shapley | Summary: Cosmology now has a standard model – a remarkably simple description of the universe, its contents and its history. A symposium held last September in Cambridge, UK, gave this model a ‘health check’ and discussed […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: D. Kandel, Roger W. Romani, , , | Summary: We present a model for atmospheric wind circulation in binary millisecond pulsar (MSP) companions, showing how the optical light curve (LC) and radial velocities (RV) are sensitive to the wind flow, causing LC orbital phase shifts and […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Chang-Tse Hsieh, Yu Nakayama, Yuji Tachikawa, , | Summary: We show that there is a fermionic minimal model, i.e. a 1+1d conformal field theory which contains operators of half-integral spins in its spectrum, for each $c=1-6/m(m+1)$, $mge 3$. This generalizes the Majorana fermion for $c=1/2$, $m=3$ and […]
Kavli Affiliate: Eli Rykoff | First 5 Authors: DES Collaboration, Tim Abbott, Michel Aguena, Alex Alarcon, Sahar Allam | Summary: We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters selected from the Dark Energy Survey (DES) Year 1 dataset. Our analysis uses the same shear and source photometric redshifts […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Christoph Engler, Annalisa Pillepich, Gandhali D. Joshi, Dylan Nelson, Anna Pasquali | Summary: We study the stellar-to-halo mass relation (SHMR) for central and satellite galaxies with total dynamical masses above 10^10.5 Msun using the suite of cosmological magneto-hydrodynamical simulations IllustrisTNG. In particular, we quantify environmental effects on […]
