I got my Ph.D. in Astrophysics working on star formation, studying numerically the effect of magnetic field on star formation processes. I have a strong interest in high performance computing, computational science, physics and astrophysics. I even have the chance to do these things for a living. I am a daily user of Python, Fortran, parallel libraries such as MPI & OpenMP and a bunch or other programming languages and libraries. I am also a TeX/LaTeX user (and enthousiast!) for years, always thrilled to discover all the things you can do with these tools. Finally, I am a GNU/Linux user and supporter, and I strongly believe in the power of sharing knowledge and culture.

My profile picture is a photograph of a statue of Nicolas Copernicus in his hometown of Toruń.

comment Synthesising types of galaxies using various stellar spectra
For the simple kind of synthesis you want to do, you probably want to have a look on Faber (1972) paper. For more complicated stuff (with a proper Initial Mass Function and a Star Formation History), you will definitely want to have a look on the Bruzual & Charlot (2003) paper.

revised How dense are Saturn's rings?
Correct some mistakes in the answer, plus add crunchy details (actual estimate of the density, and illustration of the optical depth)

comment Why is our solar system “tipped” about 63° with respect to the plane of our galaxy?
You can have a look on the Kepler data, that shows the same kind of trend (lots of exoplanets with large axial tilt). So it seems that our Solar System is not very generic, but it isn't weird either from a statistic point of view. And actually, our situation is easier to understand from a physical point of view than all these tilted systems.
