CREDO Detector vs Make Chirps

What is CREDO Science? Cosmic-Ray Extremely Distributed Observatory (CREDO) — Citizen Science collaborative project which enables a strategy for a global analysis of cosmic-ray data to reach the sensitivity to extremely extended cosmic-ray phenomena, we call them Cosmic-Ray Ensembles (CRE), invisible for individual detectors or observatories. So far, the cosmic-ray research has been oriented on detecting single air showers only, while the search for CRE is a scientific terra incognita. We aim at exploring this uncharted realm. Observation of CRE would have an impact on cosmology, fundamental particle interactions and ultra-high energy astrophysics. A large role in the CREDO project is the CREDO Detector mobile app, which uses the camera's matrix to register cosmic-ray particles. By creating a network of users around the globe, we get a cosmic-ray telescope the size of the whole Earth. All application code is public and available on our GitHub. CREDO is an open Citizen Science collaborative project and all collected data are public. In the project participate schools and institutions from 5 continents. If you think your school should join the program, contact us at contact@credo.science. If you have an idea and desire to implement it, you are welcome to join us!

This educational app displays gravitational wave chirps created by mergers of massive black holes in several different ways, giving users an intuitive understanding of these exotic disturbances of space-time itself produced by cataclysmic events in distant galaxies. FEATURES: • Simulation: Experience the intricate behavior of gravitational waves through physics simulation of inspiralling black holes that merge to form a final black hole which then “shakes off” its excess energy. • Visualizations: See the essence of gravitational waves via waveform plots, frequency evolutions, and spectrograms, to understand the patterns and how they depend on black hole masses. • Auditory Experience: Listen closely as you hear the evolution of gravitational waves, detecting the characteristic increase in time in strength and frequency. Try varying masses to see how pitch is affected. • Dynamic Animations: Witness the captivating dance of black holes in collision animations. Explore the propagation of these waves through space-time with mesmerizing spiral animations. • Educational Insights: Gain a comprehensive understanding of gravitational waves and the pioneering work of LIGO through informative text pages, enhancing your knowledge of these cosmic phenomena. COMPATIBILITY Compatible with iPhone and iPad, iOS 16 or later. ACKNOWLEDGEMENT Supported by the National Science Foundation with grant PHY-2110181.
