Stress tensor mesostructures for freeform shaping of thin substrates

Kavli Affiliate: Youwei Yao | First 5 Authors: Youwei Yao, Brandon Chalifoux, Ralf Heilmann, Mark Schattenburg, | Summary: Stress-induced shaping, which deforms thin substrates utilizing stressed surface coatings, has enabled and enhanced a host of applications in past decades. Owing to the touchless fabrication process compatible with modern planar technology, the method has been applied […]

Revised event rates for extreme and extremely large mass-ratio inspirals

Kavli Affiliate: Xian Chen | First 5 Authors: Verónica Vázquez-Aceves, Lorenz Zwick, Elisa Bortolas, Pedro R. Capelo, Pau Amaro-Seoane | Summary: One of the main targets of the Laser Interferometer Space Antenna (LISA) is the detection of extreme mass-ratio inspirals (EMRIs) and extremely large mass-ratio inspirals (X-MRIs). Their orbits are expected to be highly eccentric […]

Entropy-Conserving Scheme for Modeling Nonthermal Energies in Fluid Dynamics Simulations

Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Vadim A. Semenov, Andrey V. Kravtsov, Benedikt Diemer, , | Summary: We compare the performance of energy-based and entropy-conservative schemes for modeling nonthermal energy components, such as unresolved turbulence and cosmic rays, using idealized fluid dynamics tests and isolated galaxy simulations. While both methods are aimed […]

What it Takes to Measure Reionization with Fast Radio Bursts

Kavli Affiliate: George Efstathiou | First 5 Authors: Stefan Heimersheim, Nina S. Sartorio, Anastasia Fialkov, Duncan R. Lorimer, | Summary: Fast Radio Bursts (FRBs) are recently-discovered extra-galactic radio transients which exhibit a distance-dependent dispersion of their signal, and thus can be used as cosmological probes. In this article we, for the first time, apply a […]

HD 183579b: A Warm Sub-Neptune Transiting a Solar Twin Detected by TESS

Kavli Affiliate: Edward H. Morgan | First 5 Authors: Tianjun Gan, Megan Bedell, Sharon Xuesong Wang, Daniel Foreman-Mackey, Jorge Meléndez | Summary: We report the discovery and characterization of a transiting warm sub-Neptune planet around the nearby bright ($V=8.75$ mag, $K=7.15$ mag) solar twin HD 183579, delivered by the Transiting Exoplanet Survey Satellite (TESS). The […]

Models of Hidden Purity

Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, , , , | Summary: I extend, apply, and generalize a model of a quantum radiator proposed by Griffiths to construct models of radiation fields that exhibit high entropy for long periods of time but approach pure states asymptotically. The models, which are fully consistent […]

Blueshifted hydrogen emission and shock wave of RR Lyrae variables in SDSS and LAMOST

Kavli Affiliate: Huawei Zhang | First 5 Authors: Xiao-Wei Duan, Xiaodian Chen, Weijia Sun, Licai Deng, Huawei Zhang | Summary: Hydrogen emissions of RR Lyrae variables are the imprints of shock waves traveling through their atmospheres. We develop a pattern recognition algorithm, which is then applied to single-epoch spectra of SDSS and LAMOST. These two […]

Mock catalogues of emission line galaxies based on the local mass density in dark-matter only simulations

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ken Osato, Takahiro Nishimichi, Masahiro Takada, , | Summary: The high-precision measurement of spatial clustering of emission line galaxies (ELGs) is a primary objective for upcoming cosmological spectroscopic surveys. The source of strong emission of ELGs is nebular emission from surrounding ionized gas irradiated by massive short-lived […]
