Kavli Affiliate: Michael Crisler | First 5 Authors: Liron Barak, Itay M. Bloch, Ana Botti, Mariano Cababie, Gustavo Cancelo | Summary: We use a science-grade Skipper Charge Coupled Device (Skipper-CCD) operating in a low-radiation background environment to develop a semi-empirical model that characterizes the origin of single-electron events in CCDs. We identify, separate, and quantify […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Deep Chatterjee, Abhishek Hegade K. R., Gilbert Holder, Daniel E. Holz, Scott Perkins | Summary: Gravitational-wave cosmology began in 2017 with the observation of the gravitational waves emitted in the merger of two neutron stars, and the coincident observation of the electromagnetic emission that followed. Although […]
Kavli Affiliate: Austin Joyce | First 5 Authors: Daniel Baumann, Wei-Ming Chen, Carlos Duaso Pueyo, Austin Joyce, Hayden Lee | Summary: Much of the structure of cosmological correlators is controlled by their singularities, which in turn are fixed in terms of flat-space scattering amplitudes. An important challenge is to interpolate between the singular limits to […]
Kavli Affiliate: Angela V. Olinto | First 5 Authors: Claire Guépin, Roberto Aloisio, Luis A. Anchordoqui, Austin Cummings, John F. Krizmanic | Summary: High to ultrahigh energy neutrino detectors can uniquely probe the properties of dark matter $chi$ by searching for the secondary products produced through annihilation and/or decay processes. We evaluate the sensitivities to […]
Kavli Affiliate: Thomas M. Crawford | First 5 Authors: Prashant Kocherlakota, Luciano Rezzolla, Heino Falcke, Christian M. Fromm, Michael Kramer | Summary: Our understanding of strong gravity near supermassive compact objects has recently improved thanks to the measurements made by the Event Horizon Telescope (EHT). We use here the M87* shadow size to infer constraints […]
Kavli Affiliate: Albert Stebbins | First 5 Authors: Anh Phan, Santanu Das, Albert Stebbins, Peter Timbie, Reza Ansari | Summary: Hydrogen intensity mapping is a new field in astronomy that promises to make three-dimensional maps of the matter distribution of the Universe using the redshifted $21,textrm{cm}$ line of neutral hydrogen gas (HI). Several ongoing and […]
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: 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: Alexander Ji | First 5 Authors: Tyler Nelson, Yuan-Sen Ting, Keith Hawkins, Alexander Ji, Harshil Kamdar | Summary: Comoving pairs, even at the separations of $mathcal{O}(10^6),$AU, are a predicted reservoir of conatal stars. We present detailed chemical abundances of 62 stars in 31 comoving pairs with separations of $10^2 – 10^7,$AU and 3D […]
