On the origin of observed cosmic ray spectrum below 100 TV

Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Mikhail A. Malkov, Igor V. Moskalenko, , , | Summary: Significant progress in cosmic ray (CR) studies was achieved over the past decade. Particularly important are precise measurements of primary and secondary species in the TV rigidity domain that show a bump in the spectra of […]

CMB Mode Coupling with Isotropic Polarization Rotation

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 […]

Searching for a subpopulation of primordial black holes in LIGO/Virgo gravitational-wave data

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 […]

The Sloan Digital Sky Survey Reverberation Mapping Project: UV-Optical Accretion Disk Measurements with Hubble Space Telescope

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 […]

The Polarized Image of a Synchrotron Emitting Ring of Gas Orbiting a Black Hole

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 […]

Ladder Symmetries of Black Holes: Implications for Love Numbers and No-Hair Theorems

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) […]

Strange pentaquarks and excited $Ξ$ hyperons in $Ξ_b^- to J/ψ ΛK^-$ final states

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 […]
