UPPER PANEL: The gas surface density map in log scale. The red circle in the center represents the central protostar. The development of spiral structure in the protostellar disk is evident. Dense protostellar/protoplanetary clumsp form within the spiral arms and are driven into the protostar by the action of gravitational torques. LOWER PANEL: The mass accretion rate onto the protostar as a function of time. The mass accretion rate is characterized by very short ( . ...

... Angular fluctuations in the CXB: Is Fe 6.4 keV line tomography of the large-scale structure feasible ? ... Due to cosmological redshift , the line photons detected at the energy E carry information about objects located at the redshift z=6.4/E-1. ... The signal is strongest for objects located at the redshift z~1, and at the angular scales corresponding to l ~ 100-300, therefore an optimal detection can be achieved with an instrument having a rather modest angular resolution of ~ 0.1-0.5 deg. ...

Two of the molecular clouds studied by Kainulainen and colleagues: The Pipe Nebula (left) and the Rho Ophiuchi cloud (right) in the Milky Way. In the background, an ordinary image of the Milky Way; each inset map shows to what extent the light of background stars is dimmed as it passes through the cloud in question. These maps form the basis of the 3-D reconstruction of cloud structure from which the astronomers derived their "recipe for star formation." ...
