Our results can be tested directly in the next few years, for example by ASTRO-H. Instead of sending emojis, make it enjoyable by sending our Spiral GIFs to your conversation. The simplest two-component model reproduces several key properties of CCs, so we propose that all such cores harbor a spiral flow. Tons of hilarious Spiral GIFs to choose from. Explore stunning visuals that will leave you spinning with wonder. In particular, we present a quasi-steady-state model for an accretion-quenched, composite flow, in which the fast phase is an outflow, regulated by active galactic nucleus bubbles, reproducing the observed low star formation rates and explaining some features of bubbles such as their R_b \propto r size. Get caught in a mesmerizing spiral with our captivating GIF collection. By advecting heat and mixing the gas, such flows can eliminate the cooling problem, provided that a feedback mechanism regulates the flow. This leads to the nearly logarithmic spiral pattern, two-phase plasma, \rho \sim r^ temperature) radial profile, and ~100kpc size, characteristic of CCs. 10000+ high-quality GIFs and other animated GIFs for Free on GifDB. Spiral, Circle, Whirlpool, Particles spiral circle whirlpool. We analytically show that observations of piecewise-spiral fronts impose strong constraints on the CC, implying the presence of a cold, fast flow, which propagates below a hot, slow inflow, separated by a slowly rotating, trailing, quasi spiral, tangential discontinuity surface.

Such flows are gauged by spiral features in the thermal and chemical properties of the intracluster medium, by the multi-phase properties of CCs, and by X-ray edges known as cold fronts.
