How Small Were the First Cosmological Objects?
The minimum mass that a virialized gas cloud must have in order to be able to cool in a Hubble time is computed, using a detailed treatment of the chemistry of molecular hydrogen. With a simple model for halo proÐles, we reduce the problem to that of numerically integrating a system of chemical equations. The results agree well with numerically expensive three-dimensional simulations, and our a...

The minimum mass that a virialized gas cloud must have in order to be able to cool in a Hubble time is computed, using a detailed treatment of the chemistry of molecular hydrogen. With a simple model for halo profiles, we reduce the problem to that of numerically integrating a system of chemical equations. The results agree well with numerically expensive 3D simulations, and our approach has th...
متن کاملHow Big Were the First Planetesimals? Does Size Matter?
Introduction: The terrestrial planets formed by collisional accretion of small planetesimals [1,2]. Stochastic coagulation and runaway growth yield an “oligarchy” of embryos with similar sub-planetary masses [3] that then collide to yield planets [4-5]. A common assumption is km-sized initial planetesimals, based on the scale of gravitational instability in a dust layer in a quiescent solar neb...
متن کاملHow Saqaliba slaves were transferred to Andalusia in the Umayyad period
Slave bargain that was common in the West of Europe for a long time continued after the conquer of Andalusia by Muslims in the last decade of the first century A.H. Meanwhile, slaves from the northern regions of Spain, especially Slavic lands, entered the Andalusian markets. These slaves, known in medieval Islamic sources as Saqaliba, were often bought by Jewish merchants and transferred to And...
متن کاملWere Gram-positive rods the first bacteria?
At some point in the evolution of life, the domain Bacteria arose from prokaryotic progenitors. The cell that gave rise to the first bacterium has been given the name (among several other names) "last universal ancestor (LUA)". This cell had an extensive, well-developed suite of biochemical strategies that increased its ability to grow. The first bacterium is thought to have acquired a covering...
