Ultrahigh-energy photons up to 1.4 petaelectronvolts from 12 γ-ray Galactic sources

Zhen Cao et al.

Summary: The extension of the cosmic-ray spectrum beyond 1 petaelectronvolt indicates the existence of PeVatrons, cosmic-ray factories that accelerate particles to PeV energies. Detection of ultrahigh-energy gamma radiation is a key signature of PeVatrons, with ongoing efforts to locate and identify these extreme accelerators. Despite detecting high-energy gamma rays from various sources, the exact origin and identity of the PeVatrons responsible for the ultrahigh-energy gamma rays remain unknown.

First Detection of sub-PeV Diffuse Gamma Rays from the Galactic Disk: Evidence for Ubiquitous Galactic Cosmic Rays beyond PeV Energies

M. Amenomori et al.

Summary: For the first time, researchers have detected diffuse gamma rays with energies between 100 TeV and 1 PeV in the Galactic disk. This provides strong evidence that cosmic rays are accelerated beyond PeV energies in our Galaxy and spread over the Galactic disk.

Galactic spiral structure revealed by Gaia EDR3

E. Poggio et al.

Summary: By utilizing astrometry and integrated photometry data from the Gaia Early Data Release 3, this study maps the density variations of young upper main sequence (UMS) stars, open clusters, and classical Cepheids in the Galactic disc, revealing the location and extent of spiral arm segments. The resulting maps show large-scale arches with over-dense regions matching the distribution of bright open clusters, while the geometry of the arms in the III quadrant differs significantly from previous models, suggesting a larger pitch angle for the Perseus arm and a longer extent of the Local Arm.

Origin of Galactic Sub-PeV Diffuse Gamma-Ray Emission: Constraints from High-energy Neutrino Observations

Ruo-Yu Liu et al.

Summary: Recently discovered diffuse gamma-rays from the Galactic disk in a specific energy range may be related to conventional Galactic cosmic-ray propagation models, but tension arises with the non-detection of Galactic neutrino emissions by the IceCube neutrino telescope. Further analysis suggests that the presence of additional cosmic-ray components from sources like the Cygnus Cocoon region could alleviate this tension, implying the existence of extreme accelerators in the Cygnus region.

The highest energy HAWC sources are likely leptonic and powered by pulsars

Takahiro Sudoh et al.

Summary: The HAWC Collaboration observed gamma rays at energies above 56 TeV from nine sources, suggesting that the emission is likely of leptonic origin. This hypothesis is supported by the spectra of the objects, which favor an inverse Compton scenario.
