The large jet kinetic power and non-thermal processes occurring in the microquasar SS 433 make this source a good candidate for a very high-energy (VHE) gamma-ray emitter.

However, only a handful of such flares have been detected to date, and only within the last few years have these flares been observed from lower-frequency-peaked BL Lac objects and flat-spectrum radio quasars.

The photomeson process, which is usually suggested to operate in such a hadronic explanation, requires a rather high proton energy (>10$^{17}$ eV) for an efficient interaction.

No statistically significant signal is detected above 140 GeV.

The MAGIC telescopes carried out a deep observation campaign on UMaII between 2014 and 2016, collecting almost one hundred hours of good-quality data.

Extragalactic diffuse γ-rays from dark matter annihilation: revised prediction and full modelling uncertainties Journal of cosmology and astroparticle physics 2018(02), 005 - 005 (2018) [10.1088/1475-7516/2018/02/005]   Recent high-energy data from $Fermi$-LAT on the diffuse $\gamma$-ray background have been used to set among the best constraints on annihilating TeV cold dark matter candidates. In order to assess the robustness of these limits, we revisit and update the calculation of the isotropic extragalactic $\gamma$-ray intensity from dark matter annihilation.

During the latter, Cygnus X-1 shows a one-sided relativistic radio-jet.

The burst was detected in real time with a dispersion measure (DM) of 1105.6 ± 0.8 pc cm$^{−3}$, a pulse duration of 2.8 $^{+1.2}_{-0.5}$ ms, and a measured peak flux density assuming that the burst was at beam centre of 0.7$^{+0.2}_{-0.1}$ Jy.
