Optimal multifrequency weighting for CMB lensing

Kavli Affiliate: Blake Sherwin | First 5 Authors: Noah Sailer, Emmanuel Schaan, Simone Ferraro, Omar Darwish, Blake Sherwin | Summary: Extragalactic foregrounds in Cosmic Microwave Background (CMB) temperature maps lead to significant biases in CMB lensing reconstruction if not properly accounted for. Combinations of multi-frequency data have been used to minimize the overall map variance […]

Characterizing the FRB host galaxy population and its connection to transients in the local and extragalactic Universe

Kavli Affiliate: Kejia Lee | First 5 Authors: Shivani Bhandari, Kasper E. Heintz, Kshitij Aggarwal, Lachlan Marnoch, Cherie K. Day | Summary: We present the localization and host galaxies of one repeating and two apparently non-repeating Fast Radio Bursts. FRB20180301A was detected and localized with the Karl G. Jansky Very Large Array to a star-forming […]

The Secret Higgstory of the Highest Temperature during Reheating

Kavli Affiliate: Wayne Hu | First 5 Authors: Samuel Passaglia, Wayne Hu, Andrew J. Long, David Zegeye, | Summary: We study the role of the Standard Model Higgs condensate, formed during cosmological inflation, in the epoch of reheating that follows. We focus on the scenario where the inflaton decays slowly and perturbatively, so that there […]

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 […]

SOFIA-upGREAT imaging spectroscopy of the [C II] 158um fine structure line of the Sgr B region in the Galactic center

Kavli Affiliate: R. Morris | First 5 Authors: A. I. Harris, R. Güsten, M. A. Requena-Torres, D. Riquelme, M. R. Morris | Summary: We report SOFIA-upGREAT spectroscopic imaging of the [C II] 158um spectral line, as well as a number of [O I] 63um spectra, across a 67×45 pc field toward the Sgr B region […]

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 […]
