In order to explore the statistical properties of galaxy morphological types\nin compact groups (CGs), we construct a random group sample which has the same\ndistributions of redshift and number of member galaxies as those of the CG\nsample. It turns out that the proportion of early-type ...
obtained. The power-law index γ increases with decreasing absolute magnitude of sample galaxies M abs . At M abs ∼ −21.4,which corresponds to the characteristic value M ∗ r of the SDSS luminosity function, this dependence exhibits a break followed by a more rapid increase in γ. ...
One approach to identify the progenitors of Type IIP SNe in nearby galaxies is by means of high resolution archival images from space and ground-based telescopes. Among 45 Type IIP SNe with either detected progenitors or upper limits, it was found (Smartt, 2015) a remarkable deficit of stars...
What are the main types of AGN that exhibit broad and strong emission lines? The main types of AGN that exhibit broad and strong emission lines are quasars, blazars, and Seyfert galaxies. These are all highly active and luminous types of AGN, with strong emission lines...
A Census of Massive Stars Across the Hertzsprung-Russell Diagram of Nearby Galaxies: What We Know and What We Don't When we look at a nearby galaxy, we see a mixture of foreground stars and bona fide extragalactic stars. I will describe what we need to do to get meaningf... P Massey...
at first it'll start out quite small, having a low density (compared to earth), but quite a significant density when compared to stars and galaxies. that 2nd-ray installation will power the only-attraction side of things and be our source of "unwanted". our goal and desire will be to ...
