Wrapping up 10 days in China by catching up with my undergrad adviser (after 16 years), friends, and collaborators... thanks for the fantastic visits, Tsinghua and Jiao Tong! A truly memorable trip. Apologies to all the ducks that got harmed in the process.

3) Advanced cosmological parameters: different dark energy models, relativistic species, etc.

4) Advanced calculations: correlation functions, peak height, etc. Power spectra can be calculated via fitting functions or using CAMB.

So what can Colossus-Web do? A few highlights:

1) Graphical interface: you can plot tons of cosmological functions and download the data to csv files.

2) Multiple cosmologies: you can compare as many pre-programmed cosmologies as you want, or create your own.

Need the age of the Universe at z = 5 but only got a phone? Wanna compute a correlation function without python? Fear not, for we are proudly presenting Colossus-Web, a powerful online cosmology calculator!
