Kiloparsec-Scale Jets in FR I Radio Galaxies and the γ-Ray Background [PDF]
, 2005 We discuss the contribution of kiloparsec-scale jets in FR I radio galaxies to the diffuse γ-ray background radiation. The analyzed γ-ray emission comes from inverse-Compton scattering of starlight photon fields by the ultrarelativistic electrons whose ...

Nowcasting Solar Energetic Particle Events for Mars Missions
Space Weather, Volume 23, Issue 4, April 2025.Abstract In addition to the omnipresent Galactic Cosmic Rays, sudden Solar Energetic Particle (SEP) events present considerable health hazards for manned space missions. These events not only contribute to an increased long‐term cancer risk, but can, in extreme cases, cause acute radiation syndromes.

Cosmic Rays and the Askaryan Effect Reveal Subsurface Structure and Buried Ice on the Moon
Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.Abstract We present the first full‐wavelength numerical simulations of the electric field generated by cosmic ray impacts into the Moon. Billions of cosmic rays fall onto the Moon every year. Ultra‐high energy cosmic ray impacts produce secondary particle cascades within the regolith and subsequent coherent, wide‐bandwidth, linearly‐polarized radio ...

Asymmetry of jets, lobe size and spectral index in radio galaxies and quasars [PDF]
, 1998 In this paper we investigate the correlations between spectral index, jet side and extent of the radio lobes for a sample of nearby FRII radio galaxies. In DennettThorpe et al.

Asymmetries in the jets of weak radio galaxies
, 1999 We describe a study of the side-to-side asymmetries on kpc scales in the jets of FR I radio galaxies selected from the B2 sample. The basic data are jet surface brightnesses and widths determined by fitting transverse profiles to Very Large Array (VLA ...

Relativistic precessing jets in quasars and radio galaxies : models to fit high resolution data.
, 1982 We present the formulation of generalized models tracing the geometry and intensity of the synchrotron emission from precessing, twin, relativistic jets as projected on the plane of the sky.
