About this website

Welcome to Astro-Visualization! This repository/website started as a hack project during AstroHackWeek2020. In here you can find several examples of pretty astronomical plots, and best of all, their source code! If you see a plot you like, just copy the source code and modify it to your convenience. Want to contribute with a pretty plot of your own? Check our Github repository! Feel free to share our website with the rest of the community as well! If you make use of this website in your work, please add us to your Acknowledgements: “This work has made used of the Astro-Visualization website”.

A pie in the sky

Caption: On large scales, the Universe resembles a giant web. But the appearance of this cosmic web is very different when seen through different observables. The movie shows some of these looks using a slice through the output from a numerical simulation.

Artistic galaxy tracks

Caption: The dominant matter component of the Universe is a mysterious substance dubbed Dark Matter, which drives the formation of galaxies and cosmic structure thanks to its gravitational attraction, but does not interact with light.

Galactic infall

Caption: The plots shows the trajectories followed by all stars that end up in a galaxy. The image is created from a zoom-in hydrodynamical simulation part of the ZOMG suite.

Phase space disruption

Caption: Galaxies grow over billions of years through a hierarchical process. Smaller objects merge and form larger ones, that then combine into even bigger ones. Most of these events involve galaxies with very unequal mass, and the fate of the smaller objects can be very different depending on their size and orbit.

PISCOLA Fits

Caption: Gaussian Process (GP) fit of the multi-colour light curves of SN 03D1au. A Matérn-5/2 kernel was used in this case. The solid lines show the mean of the GP fits while the shaded areas represent one standard deviation (1-$\sigma$).

PISCOLA Flowchart

Caption: Flowchart of the main procedures in PISCOLA. Gaussian Process is used to fit the light curves of SNe Ia. Afterwards, an SED template is warped to match the observed SN colors, which is then corrected for redshift (K-correction) and Milky Way dust extinction.
