“…Thus, the first-order LIV should be readily excluded. Our results are consistent with results from other probes such as the vacuum birefringence [17,18], which give constraints many orders of magnitude higher than the Planck scale, and is thus an independent confirmation of the conclusion that the first-order superluminal LIV should not be present. The second-order LIV energy scale reaches 10 −3 times of the Planck scale, as derived from the γ → 3γ process.…”

“…The dominant splitting process is 𝛾 → 3𝛾.In the superluminal scenario, the decay or splitting of high-energy 𝛾-ray results in a sharp cutoff of the energy spectrum (see Fig.5-left). Even if no signature of the LIV is found in their energy spectra, it was possible to derive lower limits on the LIV energy scale[17]. The LHAASO limits improve by at least one order of magnitude the previous results[18,19] (see Fig.5-right).…”

The Large High-Altitude Air Shower Observatory (LHAASO) opened the multi-TeV era in 𝛾astronomy and cosmic ray physics. Since July 2021, LHAASO is fully operational and collecting high-quality data. A Nature paper in 2021, revealing 12 VHE new sources, was just the start of LHAASO science, revealing the huge scientific potential of LHAASO. Many analysis efforts are ongoing in different areas and several results are already published. In this contribution, we will show some highlights from LHAASO science in particular on the Crab SED at PeV energies, the new limits on the Lorentz Invariance Violation and Dark Matter.

“…LHAASO also detected PeV gamma-ray emission from the Crab Nebula, revealing an extreme electron accelerator with unprecedented high accelerating efficiency (LHAASO Collaboration et al 2021). These observation involving the highest gamma-ray energy also shed light on exploring the Lorentz invariance violation (Cao et al 2022a) and dark matter (Cao et al 2022b). It is worth noting that these results were achieved using only 1 year of data and half of the LHAASO array prior to completion of its construction.…”

We present the first catalog of very-high-energy and ultra-high-energy gamma-ray sources detected by the Large High Altitude Air Shower Observatory. The catalog was compiled using 508 days of data collected by the Water Cherenkov Detector Array from 2021 March to 2022 September and 933 days of data recorded by the Kilometer Squared Array from 2020 January to 2022 September. This catalog represents the main result from the most sensitive large coverage gamma-ray survey of the sky above 1 TeV, covering decl. from −20° to 80°. In total, the catalog contains 90 sources with an extended size smaller than 2° and a significance of detection at >5σ. Based on our source association criteria, 32 new TeV sources are proposed in this study. Among the 90 sources, 43 sources are detected with ultra-high energy (E > 100 TeV) emission at >4σ significance level. We provide the position, extension, and spectral characteristics of all the sources in this catalog.
