Cosmic Rays in Galaxy Halos: Impacts on Galactic Outflows and Baryon Cycling

Ellis R. Owen, Leonard E. C. Romano, Kentaro Nagamine

Galaxies with high star-formation rate surface densities often host large-scale outflows that redistribute energy, momentum, and baryons between the interstellar medium and the hal…

GeV-TeV Connections in Galaxies: Evolutionary Signatures from Pulsars in Globular Clusters

Ellis R. Owen, Yoshiyuki Inoue, Chung-Yue Hui +2

The dominant mechanisms underlying high-energy -ray emission from galaxies vary by galaxy type. In starbursts, a major contribution comes from neutral pion decay. This is driven…

The Moon as a Cosmic-Ray Spectrometer: Prospects for MeV Gamma-Ray Observations

Tatsuki Fujiwara, Ellis R. Owen, Yoshiyuki Inoue +10

The Moon is the closest celestial gamma-ray emitting object. Its gamma-ray emission arises from interactions between Galactic cosmic rays (CRs) and the lunar surface. While the lun…

High energy extragalactic multimessenger backgrounds from starburst and dead galaxies

Ellis R. Owen, Yoshiyuki Inoue, Tatsuki Fujiwara +1

Starburst galaxies are -ray sources. Canonically, their emission is driven by hadronic cosmic rays (CRs) interacting with interstellar gas, forming -rays via the decay of neu…

Cosmic ray neutrons in magnetized astrophysical structures

Ellis R. Owen, Yoshiyuki Inoue, Tatsuki Fujiwara +2

Cosmic rays are often modeled as charged particles. This allows their non-ballistic propagation in magnetized structures to be captured. In certain situations, a neutral cosmic ray…

Starburst-Driven Galactic Outflows -- Unveiling the Suppressive Role of Cosmic Ray Halos

Leonard E. C. Romano, Ellis R. Owen, Kentaro Nagamine

Aims. We investigate the role of cosmic ray (CR) halos in shaping the properties of starburst-driven galactic outflows. Methods. We develop a microphysical model for galactic outfl…
