5. The Radial Distribution of the Interstellar Medium in Disk Galaxies: Evidence
One possible way for spiral galaxies to internally evolve would be for gas to flow to the center and form stars in a central disk (pseudo-bulge). ... In this paper we present radial profiles of stellar and 8 ЮМm emission from polycyclic aromatic hydrocarbons (PAHs) for 11 spiral galaxies to investigate whether the interstellar medium in these galaxies contains a central concentration above that expected from the exponential disk. ...

The calculated flux distribution in the 300 to 400 nm region only fits the observed distribution closely for both the Sun and Arcturus when the complete ATLAS9 line list is used. ... Moreover, for Arcturus, even the sub-set of high quality lines can only provide a close fit to the observed high resolution spectrum if we include, ad hoc, an extra amount of continuous absorption opacity. ...

11. Alpha Centauri: The Closest Star System
... Credit Copyright: 1-Meter Schmidt Telescope , ESO Explanation: The closest star system to the Sun is the Alpha Centauri system . Of the three stars in the system, the dimmest -- called Proxima Centauri -- is actually the nearest star . The bright stars Alpha Centauri A and B form a close binary as they are separated by only 23 times the Earth- Sun distance - slightly greater than the distance between Uranus and the Sun . ...

. The relation between ellipticity and size. Red data points are the observed data; most of them have elongated shapes, and larger galaxies tend to have larger ellipticities. Gray-colored regions represent the probability distributions calculated with the computer simulations, in which two galaxies are located at so close distance that they are blended as an elongated galaxy, as shown in the right pictures schematically.

... Tidal influence on each of the galaxies in our sample is quantified by identifying and measuring the distance to the nearest companion, using a photometric technique with good completeness characteristics. ... Massnormalised starformation rates were derived using galaxy stellar masses estimated from zband luminosities Nearest companions were identified using the algorithm illustrated in Figure 1. ... Some of the lowredshift galaxies in our sample with close companions are illustrated in Figure 3. ...

14. Clumpy dust disks
... Abstract: We present Monte Carlo radiative transfer simulations for spiral galaxies modelled as a stellar disk and a two-phase clumpy dust distribution. ... As a general result, clumpy models are less opaque than the corresponding homogeneous models. ... 0.00 0.15 0.50 0.1 0.5 1.0 2.0 5.0 10.0 0.25 X . ... We have also produced several homogeneous models, to compare to the clumpy models. ... Homogeneous and clumpy models with the same tauV have the same dust mass. ...

... Resolved Stellar Populations Globular Clusters . Galaxies are made of stars, gas and the illusive dark matter. ... Star clusters are the simplest form of the stellar population. ... Old globular clusters are easily observed at great distances and can be used as probes of the early stages of star formation history in galaxies where individual stars cannot be resolved. My research interests are centered on the studies of resolved stellar populations and (old) star clusters in nearby galaxies. ...
