Abstract

We present the online service cosmICweb (COSMological Initial Conditions

on the WEB) - the first database and web interface to store, analyze,

and disseminate initial conditions for zoom simulations of objects

forming in cosmological simulations: from galaxy clusters to galaxies

and more. Specifically, we store compressed information about the

Lagrangian proto-halo patches for all objects in a typical simulation

merger tree along with properties of the halo/galaxy across cosmic time.

This enables a convenient web-based selection of the desired zoom region

for an object fitting user-specified selection criteria. The information

about the region can then be used with the MUSIC code to generate the

zoom ICs for the simulation. In addition to some other simulations, we

currently support all objects in the EAGLE simulation database, so that

for example the Auriga simulations are easily reproduced, which we

demonstrate explicitly. The framework is extensible to include other

simulations through an API that can be added to an existing database

structure and with which cosmICweb can then be interfaced. We make the

web portal and database publicly available to the community.
