Cascaded Gamma-Ray Emission Associated with the KM3NeT Ultrahigh-energy Event KM3-230213A

The Astrophysical Journal Letters
A neutrino-like event with an energy of ∼220 PeV was recently detected by the KM3NeT/ARCA telescope. If this neutrino comes from an astrophysical source or from the interaction of an ultrahigh-energy cosmic ray in the intergalactic medium, the ultrahigh ...

Gamma ray signatures of ultra high energy cosmic ray accelerators: electromagnetic cascade versus synchrotron radiation of secondary electrons

Astrophysics and Space Science, 2007
We discuss the possibility of observing ultra high energy cosmic ray sources inhigh energy gamma rays. Protons propagating away from their accelerators produce secondary electrons during interactions with cosmic microwave background photons. These electrons start an electromagnetic cascade that results in a broad band gamma ray emission.

Palamism Does Not Disfigure the Gospel: A Reply to Thomas Weinandy

International Journal of Systematic Theology, EarlyView.
Abstract In a 2024 article in the IJST, Fr. Thomas Weinandy argues that the theological system of Gregory Palamas is in grave error, especially with respect to its commitment to an objective ontological distinction between God's essence and His energies. In his concluding paragraph Fr.

Raman analysis of organic refractory materials after energetic processing: Evidence for amorphous carbon on TNOs and comets

Meteoritics &Planetary Science, EarlyView.
Abstract Amorphous carbon (αC) is found in various extraterrestrial particles, including those thought to originate from the outer Solar System. αC can form through two main processes involving C‐rich materials: exposure to energetic charged particles and thermal processing.

The Distribution of Ultrahigh-energy Cosmic Rays along the Supergalactic Plane Measured at the Pierre Auger Observatory

The Astrophysical Journal
Ultrahigh-energy cosmic rays are known to be mainly of extragalactic origin, and their propagation is limited by energy losses, so their arrival directions are expected to correlate with the large-scale structure of the local Universe.

Becoming Dostoevsky (how Rowan Williams opens up Bakhtin)

Modern Theology, EarlyView.
Abstract With the end of Communism in Russia, non‐materialist contexts were enthusiastically restored to Mikhail Bakhtin's globally famous ideas of carnival, dialogism, and polyphony. This essay surveys Rowan Williams's 2008 study Dostoevsky: Language, Faith + Fiction as a major contribution to this effort, concentrating on those general philosophical ...
