The ultra-high-energy（UhE） gamma-ray source 1lhAASO j0007+7303u is positionally associated with the composite SNr CTA1 that is located at high Galactic latitude b ≈ 10.5°. This provides a rare opportunity to spatially resolve the component of the pulsar wind nebula（PWN） and supernova remnant（SNr） at UhE. This paper conducted a dedicated data analysis of 1lhAASO j0007+7303u using the data collected from december 2019 to july 2023. This source is well detected with significances of 21σ and 17σ at 8-100 TeV and >100 TeV, respectively. The corresponding extensions are determined to be 0.23°±0.03°and 0.17°±0.03°. The emission is proposed to originate from the relativistic electrons accelerated within the PWN of PSr j0007+7303. The energy spectrum is well described by a power-law with an exponential cutoff function dN/dE =（42.4 ± 4.1）(E/（20 TeV）)-2.31±0.11exp(-E/（110±25 TeV）) TeV-1cm-2s-1in the energy range from 8 to 300 TeV, implying a steady-state parent electron spectrum dNe/dEe∝(Ee/（100 TeV）)-3.13±0.16exp[(-Ee/（373±70 TeV）)2] at energies above ≈ 50 TeV. The cutoff energy of the electron spectrum is roughly equal to the expected current maximum energy of particles accelerated at the PWN terminal shock. Combining the x-ray and gamma-ray emission, the current space-averaged magnetic field can be limited to≈ 4.5 μG. To satisfy the multi-wavelength spectrum and the γ-ray extensions, the transport of relativistic particles within the PWN is likely dominated by the advection process under the free-expansion phase assumption.

We report the detection of an extended very-high-energy(VhE) γ-ray source coincident with the location of middle-aged(62.4 kyr) pulsar PSr j0248+6021, by using the lhAASO-WCdA data of live 796 d and lhAASO-KM2A data of live 1216d. A significant excess of γ-ray induced showers is observed both by WCdA in energy bands of 1-25 Te V and KM2A in energy bands of >25 TeV with 7.3σ and 13.5σ, respectively. The best-fit position derived through WCdA data is r.A. = 42.06°± 0.12°and dec. = 60.24°± 0.13°with an extension of 0.69°±0.15°and that of the KM2A data is r.A.= 42.29°± 0.13°and dec. =60.38°± 0.07°with an extension of 0.37°±0.07°. No clear extended multiwavelength counterpart of this lhAASO source has been found from the radio band to the GeV band. The most plausible explanation of the VhE γ-ray emission is the inverse Compton process of highly relativistic electrons and positrons injected by the pulsar. These electrons/positrons are hypothesized to be either confined within the pulsar wind nebula or to have already escaped into the interstellar medium, forming a pulsar halo.

In this paper, we report the detection of the very-high-energy (VhE, 100 Ge V100 TeV) γ-ray emissions from the direction of the young star-forming region W43, observed by the large high Altitude Air Shower Observation (lhAASO). The extended γ-ray source was detected with a significance of～16σby KM2A and～17σby WCdA, respectively. The angular extension of this γ-ray source is about 0.5 degrees, corresponding to a physical size of about 50pc. We discuss the origin of the γ-ray emission and possible cosmic ray acceleration in the W43 region using multi-wavelength data. Our findings suggest that W43 is likely another young star cluster capable of accelerating cosmic rays (Crs) to at least several hundred TeV.

Tumor necrosis factor receptor(TNFr)-associated factor 6(TrAF6)is a key regulator of the innate immune system,activating NF-κb and AP-1 signaling[1].TrAF6 participates in the immune regulation of many diseases,especially in chronic infections caused by pathogenic bacteria,such as Mycobacterium tuberculosis(Mtb)-induced tuberculosis(Tb)[2].
