... spectrum . ffit . ... grids . ... These commands read in a grid of model spectra. ... Values for the parameters are taken from the input models themselves, to avoid mixups. The syntax of the command arguments is precise. model{ . ... If there is only one spectrum to fit, one should set default parameters for the secondary which lie within the model grid, with <L_2/L> being a very small value. ... The output is saved in a file <file.fit> , where <file> was the name of the spectrum being fitted. ...

... arXiv.org . astro-ph . ... We fit the near-infrared to radio spectral energy distributions of 30 luminous and ultra-luminous infrared galaxies with pure starburst models or models that include both starburst and AGN components to determine important physical parameters for this population of objects. In particular we constrain the optical depth towards the luminosity source, the star formation rate, the star formation efficiency and the AGN fraction. ...

... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...

External influences on spin parameters for INTERBALL - AP . ... The main interest is that almost all kind of external influences to parameters of motion (eclipse, normalization, ROS) are presented in the one time interval. Three upper panels illustrate the spin velocity, the angle between kinetic moment and sun direction, and the nutation.All external events are represented on the lowest panel as blue, green and yellow columns. ...

. In this comparison of actual observations with simulations, the top images show Hubble observations of the density of gas in the central portion of two galaxies. The bottom images are computer simulations that are remarkably similar to the Hubble observations. Knots of star formation in the two galaxies show how gas falling into a galaxy's center is controlled by jets from the central black hole. NASA/ESA/M. Donahue (Michigan State Univ.)/Y.

Thus, the initial pulse of the rotation of a protosolar cloud of the solar system was determined as a result of the diversion of a part of the moment of the rotational pulse of the Galaxy. ... Besides this new approach to the pre-solar system as a system of the destroyed vortex structure, we can understand now a number of other peculiarities of the Solar system's structure. ...

It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...
