Selected Recent & Representative Publications

1. Cosmic ray heating of cold streams: Implications for the gas supply and growth of massive galaxies
Owen, Ledos, Ntormousi, Takasao, Nagamine & Cantalupo (2026)

Submitted to A&A

Cosmic rays preferentially heat diffuse and mixed cold-stream gas, making gas accretion onto massive galaxies more vulnerable while dense stream cores remain relatively resilient.

[arXiv] [ADS]

2. Multiwavelength Probes of Cosmic Ray Transport in Molecular Cloud Structures
Ng, Owen, Tsuji & Chen (2026)

PASJ, 78, 1390–1410

A multiwavelength framework connecting cosmic-ray transport in dense molecular gas to gamma-ray emission, ionisation profiles and hard X-ray synchrotron signatures, with applications to the Taurus molecular cloud complex.

[Journal] [arXiv] [ADS]

3. The “Forgotten” Neutrons: Implications for the Propagation of High-Energy Cosmic Rays in Magnetized Astrophysical and Cosmological Structures
Owen, Wu, Inoue, Fujiwara, Han & Ng (2026)

Universe, 12, 94

Hadronic interactions can temporarily convert high-energy cosmic-ray protons into uncharged neutrons, allowing ballistic steps that modify confinement and escape from galaxies, clusters and cosmic-web filaments.

[Journal] [arXiv] [ADS]

4. Starburst-Driven Galactic Outflows: Unveiling the Suppressive Role of Cosmic Ray Halos
Romano, Owen & Nagamine (2025)

A&A, 701, L5

Established cosmic-ray halos can suppress low-velocity CR-driven galactic outflows, implying that such winds should preferentially occur in younger systems before substantial halo CR reservoirs develop.

[Journal] [arXiv] [ADS]

5. Cosmic Ray Processes in Galactic Ecosystems
Owen, Wu, Inoue, Yang & Mitchell (2023) - Invited Review

Submitted to A&A

A broad review of how cosmic rays are produced, transported and coupled to gas across galactic ecosystems, and how these processes influence feedback and galaxy evolution.

[Journal] [arXiv] [ADS]

6. The Extragalactic Gamma-Ray Background: Imprints from the Physical Properties and Evolution of Star-Forming Galaxy Populations
Owen, Kong & Lee (2022)

MNRAS, 513, 2335–2348

Models the contribution of star-forming galaxy populations to the extragalactic gamma-ray background and shows how their evolving physical properties can leave observable signatures in the diffuse gamma-ray sky.

[Journal] [arXiv] [ADS]

7. Observational Signatures of Cosmic-Ray Interactions in Molecular Clouds
Owen, On, Lai & Wu (2021)

ApJ, 913, 52

Connects magnetic structure and cosmic-ray penetration in molecular clouds to spatial variations in gas heating and ionisation, providing observational diagnostics of CR transport in dense environments.

[Journal] [arXiv] [ADS]
