Energetic Particles of Cosmic Accelerators I: Galactic Accelerators
Tonia M. Venters, Kenji Hamaguchi, Terri J. Brandt +23
The high-energy universe has revealed that energetic particles are ubiquitous in the cosmos and play a vital role in the cultivation of cosmic environments on all scales. Energetic…
Big-Bang nucleosynthesis (Particle Data Group mini-review)
Brian Fields, Subir Sarkar
A critical review is given of the current status of cosmological nucleosynthesis. In the framework of the Standard Model with 3 types of relativistic neutrinos, the baryon-to-photo…
What are Machos? Limits on Stellar Objects as the Dark Matter of our Halo
Katherine Freese, Brian Fields, David Graff
The nature of the Massive Compact Halo objects seen in microlensing experiments and interpreted as dark matter in the Halo of our Galaxy remains a mystery. Arguments are presented…
Demonstration of a Logical Architecture Uniting Motion and In-Place Entanglement
Rich Rines, Benjamin Hall, Mariesa H. Teo +35
We demonstrate a logical neutral atom architecture that integrates atom motion with in-place entanglement to achieve lower overheads than entangling-zone approaches. Using a 114-qu…
Catching Element Formation In The Act
Chris L. Fryer, Frank Timmes, Aimee L. Hungerford +216
Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects…
Big Bang Nucleosynthesis (in "The Review of Particle Properties" 2004)
Brian Fields, Subir Sarkar
A critical review is given of the current status of cosmological nucleosynthesis. In the framework of the standard model with 3 types of relativistic neutrinos, the baryon-to-photo…
Microring resonators on a membrane optical circuit for atom-light interactions
Tzu-Han Chang, Brian Fields, May E. Kim +1
We describe the design and fabrication of a scalable atom-light photonic interface based on a silicon nitride microring resonator on a transparent silicon dioxide-nitride multi-lay…
On the Evoution of the Light Elements I. D, He-3, and He-4
Brian Fields
The light elements D, \he3, \he4, and \li7 are produced in big bang nucleosynthesis and undergo changes in their abundances due to galactic processing. Since one may observe most o…
Synergies between interstellar dust and heliospheric science with an Interstellar Probe
Veerle J. Sterken, Silvan Hunziker, Kostas Dialynas +40
We discuss the synergies between heliospheric and dust science, the open science questions, the technological endeavors and programmatic aspects that are important to maintain or d…
Spatial and Spectral Modeling of the Gamma-ray Distribution in the Large Magellanic Cloud
Gary Foreman, You-Hua Chu, Robert Gruendl +3
We perform spatial and spectral analyses of the Large Magellanic Cloud (LMC) gamma-ray emission collected over 66 months by the Fermi Gamma-ray Space Telescope. In our spatial anal…
Death of Stellar Baryonic Dark Matter Candidates
Katherine Freese, Brian Fields, David Graff
The nature of the dark matter in the Universe is one of the outstanding questions in astrophysics. In this talk, I address possible stellar baryonic contributions to the 50-90% of…
High Energy Polarization of Blazars : Detection Prospects
Nachiketa Chakraborty, Vasiliki Pavlidou, Brian Fields
Emission from blazar jets in the ultraviolet, optical, and infrared is polarized. If these low-energy photons were inverse-Compton scattered, the upscattered high-energy photons re…
Limits on Stellar Objects as the Dark Matter of Our Halo: Nonbaryonic Dark Matter Seems to be Required
Katherine Freese, Brian Fields, David Graff
The nature of the dark matter in the Halo of our Galaxy remains a mystery. Arguments are presented that the dark matter does not consist of ordinary stellar or substellar objects,…
All-sky Medium Energy Gamma-ray Observatory: Exploring the Extreme Multimessenger Universe
Julie McEnery, Juan Abel Barrio, Ivan Agudo +182
The All-sky Medium Energy Gamma-ray Observatory (AMEGO) is a probe class mission concept that will provide essential contributions to multimessenger astrophysics in the late 2020s…
Energetic Particles of Cosmic Accelerators II: Active Galactic Nuclei and Gamma-ray Bursts
Tonia M. Venters, Sylvain Guiriec, Amy Y. Lien +26
The high-energy universe has revealed that energetic particles are ubiquitous in the cosmos and play a vital role in the cultivation of cosmic environments on all scales. Though th…
New Bounds for Axions and Axion-Like Particles with keV-GeV Masses
Marius Millea, Lloyd Knox, Brian Fields
We give updated constraints on hypothetical light bosons with a two-photon coupling such as axions or axion-like particles (ALPs). We focus on masses and lifetimes where decays hap…
Cosmic Ray Models for Early Galactic Lithium, Beryllium, and Boron Production
Brian Fields, Keith Olive, David Schramm
To understand better the early galactic production of Li, Be, and B by cosmic ray spallation and fusion reactions, the dependence of these production rates on cosmic ray models and…
