TeV-selected PWNe and unidentified sources yield beaming fractions of 0.1-0.3 across radio, gamma-ray, and X-ray bands, with survey-to-survey differences explained by selection biases or older pulsars and reproducible via time-dependent opening angles.
Off-peak emission from the region of 4HWC J2029+3641 is point-like with a curved spectrum consistent with the outer-gap model of the nearby pulsar PSR J2030+3641 rather than an extended nebula.
Reviews IceCube neutrino results, models Galactic plane flux from cosmic ray interactions with the interstellar medium, and discusses prospects for identifying PeVatrons via LHAASO sources.

Constraining the Pulsar Beaming Fraction with TeV-Selected Galactic Pulsar Wind Nebulae and unidentified TeV Sources
TeV-selected PWNe and unidentified sources yield beaming fractions of 0.1-0.3 across radio, gamma-ray, and X-ray bands, with survey-to-survey differences explained by selection biases or older pulsars and reproducible via time-dependent opening angles.
