Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, , , , | Summary: We provide a new analysis technique to measure the effect of the isotropic polarization rotation, induced by e.g. the isotropic cosmic birefringence from axion-like particles and a miscalibration of CMB polarization angle, via mode coupling in the cosmic microwave background […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Gabriele Franciolini, Vishal Baibhav, Valerio De Luca, Ken K. Y. Ng, Kaze W. K. Wong | Summary: With several dozen binary black hole events detected by LIGO/Virgo to date and many more expected in the next few years, gravitational-wave astronomy is shifting from individual-event analyses to population […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Y. Homayouni, Megan R. Sturm, Jonathan R. Trump, Keith Horne, C. J. Grier | Summary: We present accretion-disk structure measurements from UV-optical reverberation mapping observations of a sample of eight quasars at 0.24<z<0.85. Ultraviolet photometry comes from two cycles of Hubble Space Telescope monitoring, accompanied by […]
Kavli Affiliate: John E. Carlstrom | First 5 Authors: Ramesh Narayan, Daniel C. M. Palumbo, Michael D. Johnson, Zachary Gelles, Elizabeth Himwich | Summary: Synchrotron radiation from hot gas near a black hole results in a polarized image. The image polarization is determined by effects including the orientation of the magnetic field in the emitting […]
Kavli Affiliate: Gabor Furesz | First 5 Authors: Danielle Frostig, John W. Baker, Joshua Brown, Richard S. Burruss, Kristin Clark | Summary: The Wide-field Infrared Transient Explorer (WINTER) is a 1×1 degree infrared survey telescope under development at MIT and Caltech, and slated for commissioning at Palomar Observatory in 2021. WINTER is a seeing-limited infrared […]

Kavli Affiliate: Austin Joyce | First 5 Authors: Lam Hui, Austin Joyce, Riccardo Penco, Luca Santoni, Adam R. Solomon | Summary: It is well known that asymptotically flat black holes in general relativity have a vanishing static, conservative tidal response. We show that this is a result of linearly realized symmetries governing static (spin 0,1,2) […]
Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: We comment on the recent evidence by the LHCb Collaboration for a structure in the $J/psi Lambda$ final state produced in the decay $Xi^-_b to J/psi Lambda K^-$, with minimal quark content $c bar c u d […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Ping Yu, Jianxiong Li, Xin Li, Gisela Schuetz, Michael Hirscher | Summary: Singular beams have attracted great attention due to their optical properties and broad applications from light manipulation to optical communications. However, there has been a lack of practical schemes with which to achieve switchable […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Matthew Dodelson, Abhiram Kidambi, Jacob M. Leedom, Masahito Yamazaki | Summary: We discuss ensemble averages of two-dimensional conformal field theories associated with an arbitrary indefinite lattice with integral quadratic form $Q$. We provide evidence that the holographic dual after the ensemble average is the three-dimensional […]
