Corrections to Hawking radiation from asteroid-mass primordial black holes: analytic and numerical evaluation of the stochastic charge effect

Gabriel Vasquez, Bowen Chen, Cara Nel +3

Hawking radiation sets stringent constraints on Primordial Black Holes (PBHs) as a dark matter candidate in the g regime based on the evaporation products produced…

Effects of Primordial Black Holes on IGM History

Emily Koivu, Nickolay Y. Gnedin, Christopher M. Hirata

Currently the asteroid mass window (mass grams) remains unconstrained for Primordial Black Holes (PBHs) to make up all of the dark matter content of the uni…

MeV cosmic-ray electrons modify the TeV pair-beam plasma instability

Mahmoud Alawashra, Yuanyuan Yang, Christopher M. Hirata +2

Relativistic pair beams created in the intergalactic medium (IGM) by TeV gamma rays from blazars are expected to produce a detectable GeV-scale electromagnetic cascade, but the cas…

Resonant interactions from dynamical perturbers on generic orbits around an extreme mass ratio inspiral

Makana Silva, Harrison G. Blake-Goszyk, Christopher M. Hirata

Extreme mass-ratio inspirals (EMRIs) are binary systems where a compact object slowly inspirals into its much larger compact partner. Since we anticipate such systems to exist with…

Light in the dark forest -- I. An efficient optimal estimator for 3D Lyman-alpha forest power spectrum

N. G. Karaçaylı, C. M. Hirata

The highly anisotropic nature of the Lyman-alpha (Ly) forest data introduces a complex survey window function that complicates the measurement of the three-dimensional power spe…

Corrections to Hawking radiation from asteroid-mass primordial black holes: Numerical evaluation of dissipative effects

Emily Koivu, John Kushan, Makana Silva +3

Primordial black holes (PBHs) are theorized objects that may make up some - or all - of the dark matter in the universe. At the lowest allowed masses, Hawking radiation (in the for…

Corrections to Hawking radiation from asteroid-mass primordial black holes: description of the stochastic charge effect in quantum electrodynamics

Gabriel Vasquez, John Kushan, Makana Silva +3

Hawking radiation sets stringent constraints on Primordial Black Holes (PBHs) as a dark matter candidate in the regime based on the evaporation produc…

Compton scattering of electrons in the intergalactic medium

Yuanyuan Yang, Heyang Long, Christopher M. Hirata

This paper investigates the distribution and implications of cosmic ray electrons within the intergalactic medium (IGM). Utilizing a synthesis model of the extragalactic background…

Spot-Based Measurement of the Brighter-Fatter Effect on a Roman Space Telescope H4RG Detector and Comparison with Flat-Field Data

Andrés A. Plazas Malagón, Charles Shapiro, Ami Choi +1

We present the measurement and characterization of the brighter-fatter effect (BFE) on a NASA Roman Space Telescope development Teledyne H4RG-10 near-infrared detector using labora…
