Objective: To evaluate the efficacy.and safety.of Chinese medicine(CM) Zihua Wenfei Zhisou Granule(ZWZG) in postinfectious cough(PIC) patients with CM sy.drome of wind-cold invading Fei(Lung,WCIF). Methods: This is a multicenter, randomized, double-blind, parallel-group, placebo-controlled phase Ⅱclinical trial. PIC patients with WCIF sy.drome were recruited from the Respiratory.Departments in 6 hospitals across China between March 2019 and December 2020. Eligible patients were randomly.assigned to group A(ZWZG-matched placebo 15 g), group B(active ZWZG 15 g), and group C(active ZWZG 10 g plus ZWZGmatched placebo 5 g) in a 1:1:1 ratio.

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 analy.is 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, imply.ng 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.

LHAASO detection of very.high-energy.γ-ray.emission surrounding PSR J0248+6021

引用

Science China(Phy.ics,Mechanics & Astronomy. 2025年

We report the detection of an extended very.high-energy.VHE) γ-ray.source coincident with the location of middle-aged(62.4 ky.) 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 hy.othesized to be either confined within the pulsar wind nebula or to have already.escaped into the interstellar medium, forming a pulsar halo.

Observation of the γ-ray.emission from W43 with LHAASO

引用

Science China(Phy.ics,Mechanics & Astronomy. 2025年

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 y.ung 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 phy.ical 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 y.ung star cluster capable of accelerating cosmic ray. (CRs) to at least several hundred TeV.
