Echo-tomgraphy is an indirect imaging technique which uses multiwavelength observations of LMXBs to constrain the fundamental parameters of these binaries. In...

We present simultaneous high time resolution (1-10 Hz) X-ray and optical observations of the persistent LMXBs Sco X-l and V801 Ara( = 4 U 1636-536). In the case...

This paper will review a new technique of detecting companion stars in LMXBs and X-ray transients in outburst using the Bowen fluorescence NIII lines at 4634...

We discuss the formation and evolution of boxy/peanut bulges (B/Ps) and present new simulations results. Orbital structure studies show that B/Ps are parts of...

Boxy/peanut bulges in disk galaxies have been associated with stellar bars. We analyze their properties in a large sample of N-body simulations, using different...

Boxy/peanut bulges in disc galaxies have been associated to stellar bars. We analyse their properties in a large sample of $N$-body simulations, using different...

Boxy/peanut bulges in disk galaxies have been associated to stellar bars. In this talk, we discuss the different properties of such bulges and their relation...

In the standard cosmological model of galaxy evolution, mergers and interactions play a fundamental role in shaping galaxies. Galaxies that are currently...

Departures from a simple exponential decay (usually called breaks or truncations) in the surface brightness distribution of galaxy disks are found in the vast...
