Massive stars shape and drive our Universe. Many issues such as their formation, their stability and the mass loss effects for example, are nowadays far for...
Galaxies can be described in terms of their structure, dynamics and stellar populations. Some very robust correlations between various galaxy structural...
Pyroclastic Blowout: Dust Survival in Isolated versus Clustered Supernovae
Following the current debate on the fate of SN-condensed dust grains, I will present a set of three-dimensional hydrodynamical simulations of the interaction of...
Quantification of bar strength and the structure of galaxies
Bars are important engines for the evolution of structure in galaxies. Bars can cause secular evolution of both the gas and stellar distributions in galaxies...
Quasars as a tracer of large-scale structure at z~0.5
We present correlation between quasar properties and large-scale density with the largest spectroscopic dataset of quasars and galaxies to date. We construct a...
There is increasing speculation that quasars are intimately linked to the evolution of their host galaxies. Not only are they triggered as galaxies build up...
Quiet Sun magnetism and Alfven waves as observed with Hinode
The magnetic landscape of the polar region (Tsuneta et al, 2008) is characterized by vertical kilogauss patches with super-equipartition field strength, a...
