Amplitude modulation in binary gravitational lensing of gravitational waves

Kavli Affiliate: Ke Wang | First 5 Authors: Yi Qiu, Ke Wang, Jian-hua He, , | Summary: We investigate the detectability of gravitational waves (GWs) lensed by a system that consists of binary black holes as lenses using time-domain numerical simulations. The gravitational lensing potential of this system is no longer static but evolves with […]

More on Fake GUT

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Satoshi Shirai, Motoo Suzuki, Keiichi Watanabe, Tsutomu T. Yanagida | Summary: It is remarkable that the matter fields in the Standard Model (SM) are apparently unified into the $mathrm{SU}(5)$ representations. A straightforward explanation of this fact is to embed all the SM gauge groups into […]

Extragalactic magnetism with SOFIA (SALSA Legacy Program) — IV: Program overview and first results on the polarization fraction

Kavli Affiliate: Susan E. Clark | First 5 Authors: Enrique Lopez-Rodriguez, Sui Ann Mao, Rainer Beck, Alejandro S. Borlaff, Evangelia Ntormousi | Summary: We present the first data release of the Survey on extragALactic magnetiSm with SOFIA (SALSA Legacy Program) with a set of 14 nearby ($<20$ Mpc) galaxies with resolved imaging polarimetric observations using […]

The NICER “Reverberation Machine”: A Systematic Study of Time Lags in Black Hole X-Ray Binaries

Kavli Affiliate: Erin Kara | First 5 Authors: Jingyi Wang, Erin Kara, Matteo Lucchini, Adam Ingram, Michiel van der Klis | Summary: We perform the first systematic search of all NICER archival observations of black hole (and candidate) low-mass X-ray binaries for signatures of reverberation. Reverberation lags result from the light travel time difference between […]

Subnanometer Accuracy of Surface Characterization by Reflected-Light Differential Interference Microscopy

Kavli Affiliate: Xian Chen | First 5 Authors: Ka Hung Chan, Shengwang Du, Xian Chen, , | Summary: We theorize the surface step characterization by reflected incoherent-light differential interference microscopy with consideration of the optical diffraction effect. With the integration of localization analysis, we develop a quantitative differential interference optical system, by which we demonstrate […]

Integral field spectroscopy with the solar gravitational lens

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Alexander Madurowicz, Bruce Macintosh, , , | Summary: The prospect of combining integral field spectroscopy with the solar gravitational lens (SGL) to spectrally and spatially resolve the surfaces and atmospheres of extrasolar planets is investigated. The properties of hyperbolic orbits visiting the focal region of the SGL […]

Extragalactic magnetism with SOFIA (SALSA Legacy Program) — III: First data release and on-the-fly polarization mapping characterization

Kavli Affiliate: Susan E. Clark | First 5 Authors: Enrique Lopez-Rodriguez, Melanie Clarke, Sachin Shenoy, William Vacca, Simon Coude | Summary: We describe the data processing of the Survey on extragALactic magnetiSm with SOFIA (SALSA Legacy Program). This first data release presents 33% (51.34h out of 155.7h, including overheads) of the total awarded time taken […]

A low-eccentricity migration pathway for a 13-h-period Earth analogue in a four-planet system

Kavli Affiliate: George Ricker | First 5 Authors: Luisa Maria Serrano, Davide Gandolfi, Alexander J. Mustill, Oscar Barragán, Judith Korth | Summary: It is commonly accepted that exoplanets with orbital periods shorter than 1 day, also known as ultra-short period (USP) planets, formed further out within their natal protoplanetary disk, before migrating to their current-day […]

Fuzzballs and Microstate Geometries: Black-Hole Structure in String Theory

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Iosif Bena, Emil J. Martinec, Samir D. Mathur, Nicholas P. Warner, | Summary: The black-hole information paradox provides one of the sharpest foci for the conflict between quantum mechanics and general relativity and has become the proving-ground of would-be theories of quantum gravity. String theory has […]
