TL;DR: In this paper, a theoretical framework for understanding plasma turbulence in astrophysical plasmas is presented, motivated by observations of electromagnetic and density fluctuations in the solar wind, interstellar medium and galaxy clusters, as well as by models of particle heating in accretion disks.

TL;DR: In this paper, the authors investigated radiatively inefficient accretion flow models for Sgr A*, the supermassive black hole in our Galactic center, in light of new observational constraints.

TL;DR: In this paper, the authors have introduced new numerical methods for implementing stellar feedback on sub-GMC through galactic scales in numerical simulations of galaxies; the key physical processes include radiation pressure in the UV through IR, supernovae (Type-I & II), stellar winds (fast O star through “slow” AGB winds), and HII photoionization.

TL;DR: In this paper, the authors present and test a novel numerical implementation of stellar feedback resulting from momentum imparted to the ISM by radiation, supernovae and stellar winds, showing that stellar feedback is crucial to the regulation of star formation in galaxies.

TL;DR: In this paper, the authors predict the light curves and spectra of tidal flares as a function of time, highlighting the unique signatures of the tidal flares at optical and near-infrared wavelengths.
