Very-high-energy (VHE) gamma-ray astroparticle physics has attained a level of technical maturity that allows it to position as a distinct astronomical field. With the advent of next-generation gamma-ray facilities, astronomers from various disciplines will soon have the opportunity to utilize VHE data in their research, providing a crucial piece to the puzzle of multi-wavelength studies. Given that VHE gamma-ray astronomy has largely been a niche field, it is essential to communicate the scientific value of VHE data to the entire astronomical community. This is the primary objective of the lunch session we are proposing for the upcoming meeting of the European Astronomical Society. The timing is particularly opportune, as the construction of the Cherenkov Telescope Array Observatory (CTAO) has officially commenced, with the first telescopes set to become operational in the next three years, effectively doubling the existing capabilities in the TeV domain, and opening a new window of exploration in the tens of GeV domain, thanks to the CTAO Large-Sized Telescopes (LSTs). At the same time, particle array detectors are advancing their designs for the next generation facility, i.e. the Southern Wide-field Gamma-ray Observatory (SWGO) that has recently announced its chosen site. It is notable that both gamma-ray detection techniques ? array of imaging Cherenkov telescopes and particle array detectors ? are progressing into this new phase, even though CTAO is ahead in the deployment. This will, in fact, provide researchers the unique opportunity to leverage from the complementarity strengths of each technique, enhancing the overall impact of gamma-ray observations. We propose a lunch session to allow the attendees to benefit from a hands-on session on the VHE data analysis.
