Driving downsizing with galaxy groups
... • There are environmental influences on galaxy formation after z=1 • Probably dominant in massive groups, not clusters. • Current modeling of environmental effects is wrong and this has consequences for predictions of the general field (which is dominated by groups) Simple strangulation models may ...

... there exist two stellar clusters near SgrA*. These clusters (IRS16 and IRS13) show motions in the opposite directions (Paumard et al. 2006). How could such clusters form so near the black hole, or if they were formed originally outside the sphere of influence of the black hole, how could they migrat ...

Finding the aperture radius for photometry with SalsaJ Life Cycle of Stars
... Once you have chosen the best aperture radius, this can be set for the remainder of your photometry analysis on this image. It is advisable to carry out this exercise every time you come to work with a new set of images as the FWHM of objects change due to the seeing conditions at the time of observ ...
