SENSEI: Characterization of Single-Electron Events Using a Skipper-CCD

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 […]

Cosmology with Love: Measuring the Hubble constant using neutron star universal relations

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 […]

Indirect dark matter searches at ultrahigh energy neutrino detectors

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 […]

Constraints on black-hole charges with the 2017 EHT observations of M87*

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 […]

AlgoSCR: An algorithm for Solar Contamination Removal from radio interferometric data

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 […]

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 […]

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 […]

The Tiny (g-2) Muon Wobble from Small-$μ$ Supersymmetry

Kavli Affiliate: Marcela Carena | First 5 Authors: Sebastian Baum, Marcela Carena, Nausheen R. Shah, Carlos E. M. Wagner, | Summary: A new measurement of the muon anomalous magnetic moment has been reported by the Fermilab Muon g-2 collaboration and shows a $4.2sigma$ departure from the most precise and reliable calculation of this quantity in […]

EUSO-SPB2 sensitivity to macroscopic dark matter

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Thomas C. Paul, Sarah T. Reese, Luis A. Anchordoqui, Angela V. Olinto, Thomas Y. Chen | Summary: Macroscopic dark matter (or macro) provides a broad class of alternative candidates to particle dark matter. These candidates would transfer energy primarily through elastic scattering, and this linear energy […]

QuasarNet: A new research platform for the data-driven investigation of black holes

Kavli Affiliate: Brian Nord | First 5 Authors: Priyamvada Natarajan, Kwok Sun Tang, Robert McGibbon, Sadegh Khochfar, Brian Nord | Summary: We present QuasarNet, a novel research platform for the data-driven investigation of super-massive black hole (SMBH) populations. While SMBH data sets — observations and simulations — have grown rapidly in complexity and abundance, our […]
