Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Ryan Mckinven, Daniele Michilli, Kiyoshi W. Masui, Davor Cubranic, B. M. Gaensler | Summary: Polarimetric observations of Fast Radio Bursts (FRBs) are a powerful resource for better understanding these mysterious sources by directly probing the emission mechanism of the source and the magneto-ionic properties of its […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: Nolan Grieves, François Bouchy, Monika Lendl, Theron Carmichael, Ismael Mireles | Summary: We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exoplanet Survey Satellite (TESS) as TESS Objects of Interest […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Hsin-Yu Chen, Salvatore Vitale, Francois Foucart, , | Summary: The origin of the heavy elements in the Universe is not fully determined. Neutron star-black hole (NSBH) and {binary neutron star} (BNS) mergers may both produce heavy elements via rapid neutron-capture (r-process). We use the recent detection of […]
Kavli Affiliate: Saul Rappaport | First 5 Authors: Samuel N. Quinn, Saul Rappaport, Andrew Vanderburg, Jason D. Eastman, Lorne A. Nelson | Summary: We report the detection of a single transit-like signal in the Kepler data of the slightly evolved F star KIC4918810. The transit duration is ~45 hours, and while the orbital period ($Psim10$ […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Enrico Barausse, Emanuele Berti, Vitor Cardoso, Scott A. Hughes, Gaurav Khanna | Summary: A powerful technique to calculate gravitational radiation from binary systems involves a perturbative expansion: if the masses of the two bodies are very different, the "small" body is treated as a point particle […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Jiajin Feng, Biao Wu, Frank Wilczek, , | Summary: Interesting problems in quantum computation take the form of finding low-energy states of (pseudo)spin systems with engineered Hamiltonians that encode the problem data. Motivated by the practical possibility of producing very low-temperature spin systems, we propose and exemplify […]
Kavli Affiliate: Norbert S. Schulz | First 5 Authors: Paul B. Hemphill, Norbert S. Schulz, Herman M. Marshall, Deepto Chakrabarty, | Summary: We present an analysis of chandra/LETGS observations of the ultracompact X-ray binary (UCXB) 4U 1626$-$67, continuing our project to analyze the existing Chandra gratings data of this interesting source. The extremely low mass, […]

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Sylvia Biscoveanu, Maximiliano Isi, Vijay Varma, Salvatore Vitale, | Summary: An accurate and precise measurement of the spins of individual merging black holes is required to understand their origin. While previous studies have indicated that most of the spin information comes from the inspiral part of the […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Fakhri S. Zahedy, Hsiao-Wen Chen, Thomas M. Cooper, Erin T. Boettcher, Sean D. Johnson | Summary: (Abridged) We present a systematic investigation of physical conditions and elemental abundances in four optically thick Lyman-limit systems (LLSs) at $z=0.36-0.6$ discovered within the Cosmic Ultraviolet Baryon Survey (CUBS). CUBS […]
