Chiaki Kobayashi, Ralph Sutherland How galaxies did form and evolution? - to answer this unsolved problem, we are simulating the formation and evolutionary history of galaxies in the Universe, including star formation, supernovae feedback, and chemical enrichment. Comparing the spacial distribution of elements within galaxies with observations, we will examine fundamental physical processes that drive galaxy formation. ...

... Bojan Nikolic web pages home . ... As an exercise to put through the new InMin library through its paces, I have looked recently at applying Nested Sampling ( Skilling2006 ) algorithm to the fitting of star-formation history as function of redshift. ... The data I used are from Figure 1 of Yuksel08 but I use only the grey data paints, which are just the data originally from Hopkins2006 . ... The next step is to define the function which is the model for the history of the SFR density. ...

Next: J.G. Doyle, Research Astronomer Up: Research Previous: C.J. Butler, Research Astronomer Contents . Dr John Chambers has made detailed computer simulations of the origin and formation of the Earth and the inner planets. These build upon earlier work by Chambers and George Wetherill, of the Carnegie Institution of Washington, whose computer calculations had predicted that planets would tend to have elliptical orbits rather than the almost-circular ones we see in the Solar System. ...

On the face of it, the combined numerical N-body and hydrodynamic simulations of galaxy formation implement physical collapse models most accurately (e.g. Thomas et al. 1998) and so ought to give the most reliable results. ...

... Numerical simulations of cosmic structure formation and evolution are now suggesting that a galaxy-cosmic web connection might be the key ingredient for regulating galaxy evolution, including the morphological type, star formation history and gas content. ... This is why the most basic questions remain 50 years after the first attempts to detect intergalactic gas: Is the intergalactic medium driving star formation? ...

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 ( . ...

... This paper describes our GAMMS (Gravitational Adaptive Mesh Multigrid Solver) code, which is a numerical gravitational solver, based upon a multigrid (MG) algorithm and a local refining mesh strategy (AMR, Adaptive Mesh Refinement). ... Inside our GAMMS code, each adaptive mesh is built and controlled using the DAGH (Distributed Adaptive Grid Hierarchy) library (see http://www.caip.rutgers.edu/ ~ parashar/DAGH ). ... Tests on our AMR code show that it can efficiently handle an adaptive mesh. ...

... We have calculated the binary coalescence rate with time using the ``Scenario Machine'' code, which allows us to simulate evolution of large ensembles of binary stars in an artificial galaxy using a Monte Carlo method (see Lipunov 1992, Lipunov et al 1994, 1995 and references therein). ... The source evolution in a galaxy with given star formation rate is thus calculated as , where is the redshift at the turn-on of star formation, which is the second important parameter of the model. ...

... Star formation requires interstellar clouds that are cold and dense enough for self-gravity to overcome internal pressure from gas thermal motions and other factors, thus leading to cloud contraction and eventual collapse to stellar densities. ...

... The Russian TESIS/ CORONAS-PHOTON Solar Observatory, which has been working in orbit since January 30th, 2009, has photographed one of the most important events in the build up to the upcoming solar cycle - the formation of our star's new southern belt of activity. The first magnetic fields of the new cycle in the southern hemisphere appeared on the Sun's surface on May 23-24th. ... The belt of activity is one of the primary concepts, characterizing the solar cycle. ...
