With the number of fast-response telescopes dramatically increasing, the era of astrophysical transients has now begun. But much work remains on the theory side to be able to use observations of these transients to learn about astrophysical outbursts. I will review the difficulties in developing detailed models of astrophysical transients as well as the methods by which we hope to overcome these difficulties.

In this talk I will review the most recent observations of giant lobes in a few nearby radio galaxies such as Centaurus A or Centaurus B, as well as in starforming systems such as Circinus or Milky Way ("Fermi Bubbles"), at X-ray and gamma-ray frequencies. I will discuss the pressure balance within these structures, new evidence for a thermal gas mixed with the relativistic plasma within the lobes, and a need for a continuous acceleration of gamma-ray emitting electrons. I will argue that the structure of the extended lobes in all these systems is highly inhomogeneous and non-uniform, with magnetic reconnection and turbulent acceleration processes continuously converting magnetic energy to the internal energy of the plasma particles, leading to possibly significant spatial and temporal variations in the plasma beta parameter around the volume-averaged equilibrium condition beta ~1.

It is not known what is the maximum mass of a stellar origin black hole. Not long ago 10 Msun was commonly adopted as a BH mass limit. Now observations have demonstrated that a BH can reach at least 30 Msun. Can black holes reach mass above 100 Msun? I will discuss this issue along with several related physical processes to arrive at an observational prediction that will verify any potential answer to this question.

Stellar shells observed in many giant elliptical and lenticular as well as a few spiral and dwarf galaxies presumably result from radial minor mergers of galaxies. We show that the line-of-sight velocity distribution of the shells has a quadruple-peaked shape. We found simple analytical expressions that connect the positions of the four peaks of the line profile with the mass distribution of the galaxy, namely, the circular velocity at the given shell radius and the propagation velocity of the shell. The analytical expressions were applied to a test-particle simulation of a radial minor merger, and the potential of the simulated host galaxy was successfully recovered. Shell kinematics can thus become an independent tool to determine the content and distribution of dark matter in shell galaxies up to ~100 kpc from the center of the host galaxy. Moreover we investigate the dynamical friction and gradual disruption of the cannibalized galaxy during the shell formation in the framework of a simulation with test particles. The coupling of both effects can considerably redistribute positions and luminosities of shells. Neglecting them can lead to significant errors in attempts to date the merger in observed shell galaxies.
