Kavli Affiliate: Lee McCuller | First 5 Authors: Dhruva Ganapathy, Lee McCuller, Jameson Graef Rollins, Evan D. Hall, Lisa Barsotti | Summary: Gravitational waves produced at kilohertz frequencies in the aftermath of a neutron star collision can shed light on the behavior of matter at extreme temperatures and densities that are inaccessible to laboratory experiments. […]
Kavli Affiliate: Christopher J. Burke | First 5 Authors: Steve Bryson, Michelle Kunimoto, Ravi K. Kopparapu, Jeffrey L. Coughlin, William J. Borucki | Summary: We present occurrence rates for rocky planets in the habitable zones (HZ) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar properties. We provide the […]
Kavli Affiliate: Christopher J. Burke | First 5 Authors: Ian J. M. Crossfield, Diana Dragomir, Nicolas B. Cowan, Tansu Daylan, Ian Wong | Summary: Phase curve measurements provide a global view of the composition, thermal structure, and dynamics of exoplanet atmospheres. Although most of the dozens of phase curve measurements made to date are of […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Erin Boettcher, Hsiao-Wen Chen, Fakhri S. Zahedy, Thomas J. Cooper, Sean D. Johnson | Summary: We report the serendipitous detection of an H$_{2}$-bearing damped Lyman-$alpha$ absorber at z = 0.576 in the spectrum of the QSO J0111-0316 in the Cosmic Ultraviolet Baryon Survey. Spectroscopic observations from […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Maulik Parikh, Frank Wilczek, George Zahariade, , | Summary: We develop a formalism to calculate the response of a model gravitational wave detector to a quantized gravitational field. Coupling a detector to a quantum field induces stochastic fluctuations ("noise") in the length of the detector arm. The […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Maulik Parikh, Frank Wilczek, George Zahariade, , | Summary: For the purpose of analyzing observed phenomena, it has been convenient, and thus far sufficient, to regard gravity as subject to the deterministic principles of classical physics, with the gravitational field obeying Newton’s law or Einstein’s equations. Here […]
Kavli Affiliate: Moritz Guenther | First 5 Authors: Nancy Remage Evans, H. Moritz Guenther, Howard E. Bond, Gail H. Schaefer, Brian D. Mason | Summary: Cepheids in multiple systems provide information on the outcome of the formation of massive stars. They can also lead to exotic end-stage objects. This study concludes our survey of 70 […]
Kavli Affiliate: Herman Marshall | First 5 Authors: Daniel Schwartz, Aneta Siemiginowska, Brad Snios, Diana Worrall, Mark Birkinshaw | Summary: We report the detection of extended X-ray emission from two high-redshift radio quasars. These quasars, J1405+0415 at $z$=3.208 and J1610+1811 at $z$=3.118, were observed in a Chandra snapshot survey selected from a complete sample of […]

Kavli Affiliate: Anna Frebel | First 5 Authors: Kaitlin C. Rasmussen, Joseph Zepeda, Timothy C. Beers, Vinicius M. Placco, Eric Depagne | Summary: We present the first release of a large-scale study of relatively bright (V < 13.5) metal-poor stars observed with the Southern African Large Telescope (SALT), based on high-resolution spectra of 50 stars […]
