We present six case studies from a broad mass range (1 - 109 M_\odot) of astrophysical objects, each of which exhibit signs of jets and emit intense high energy gamma rays (>10 GeV). Many of these objects also emit spatially identifiable ultra high energy cosmic rays (UHECRs). In all cases it is found that wakefield acceleration (WFA) explains both the global properties and details. For blazars, we also explain the temporal structure of these signals, which includes neutrinos, and the correlations in their "bursts" and anti-correlation in flux and index. Blazars (∼ 109 M_\odot), radio galaxies (∼ 108 M\odot), Seyfert galaxies (∼ 106 M\odot), starburst galaxies (∼ 103 M\odot), down to microquasars (1 ∼ 10 M_\odot) interestingly exhibit the same physics since the nature of the accretion and acceleration is independent of the mass, aside from maximum values. It is possible to accelerate electrons to energies much greater than 10 GeV, and protons beyond 1020 eV with WFA. We compare observational values with theoretical ones to illustrate they are in good agreement. This mechanism is also accompanied by related emissions, such as high-energy pin-pointed neutrinos, time varying radio, optical, and X-ray emissions, opening an opportunity to characterize these astrophysical objects via multi-messenger approaches.
