Solar prominences are cool and dense plasma suspended in the million-degree solar corona. Recent observations reveal that prominences are composed of fine and...

After presenting three ways of defining a bulge component in disk galaxies, we introduce the various types of bulges, namely the classical bulges, the boxy...

We present results on the formation and evolution of Galaxies with the Spitzer Wide-area Infrared Extragalactic Survey SWIRE Lonsdale et al 2003 the largest of...

We explore the formation and evolution of hydrogen-deficient post-AGB white dwarf stars by computing the complete evolution of an initially 2.7 Msun star from...

We summarize our work on structures in different stages of aggregation, and spanning a wide range in redshift. We emphasize our work on high resdhift clusters...

Solar prominences are composed of many threads of cool and dense plasma suspended in the million-degree solar corona. We have constructed a 3D time-dependent...
