Using high resolution, two-dimensional hydrodynamical simulations, we investigate the evolution of a self-gravitating multi-phase interstellar medium in the central kiloparsec region of a galactic disk. We find that a gravitationally and thermally unstable disk evolves, in a self-stabilizing manner, into a globally quasi-stable disk that consists of cold (T<100 K), dense clumps and filaments surrounded by hot (T>10^4 K), diffuse medium. In the quasi-stable phase where cold and dense clouds are formed, the effective stability parameter, Q, has a. value in the range 2-5. The dynamic range of our multi-phase calculations is 10^6 - 10^7 in both density and temperature. We also succeeded in modeling star formation in the multi-phase ISM with 2 pc resolution. Massive stars formed in the dense, cold clouds are tracked for their life time, and finally explode as SNe.

We investigate whether pc-scale jets of 3C 345 and 3C 279 are dominated by a normal plasma or an electron-positron plasma. We present a general condition that a jet component becomes optically thick for synchrotron self-absorption. The general condition gives a lower limit of the electron number density, with the aid of the surface brightness condition, which enables us to compute the magnetic field density. Comparing the lower limit with another independent constraint that is deduced from the kinetic luminosity, we can distinguish the matter content. We apply the procedure to the five components of 3C 345 (C2, C3, C4, C5, and C7) and the three components of 3C 279 (core, C3 and C4) of which angular diameters and radio fluxes at the peak frequencies were obtainable from literature. Evaluating the Doppler factors by their equipartition values, we find that four of the five components of 3C 345 and all the three components of 3C 279 are likely dominated by an electron-positron plasma.

Late-time entropy productions due to the decay of non-relativistic massive particles influences the standard scenario. If the matter-dominated epoch continues so long that the radiation-domination can not be realized completely at a cosmic time t[〜!_] 1 sec, the universe would fail to produce the light elements. We find that the reheating temperature T_R should be greater than 0.5 MeV in order to agree with observations.
