Galaxy Inclination Zoo

Welcome !

This is the Cosmicflows4 collaborative Inclination project. Your contribution to this project would be appreciated. Cosmicflows is an ambitious project to map out our local universe ...

The goal of this project is to find the distance of about 20,000 spiral galaxies using the correlation between their rotation rate and absolute luminosity, known as the Tully-Fisher Relation (TFR). To measure the rotation speed, we use the atomic Hydrogen 21 cm line width. Since both inclination and rotation speed of these galaxies contribute to the line width, we need to precisely measure the inclination of these galaxies. To achieve this goal, we have designed a GUI to visually inspect these galaxies by inserting them between a set of standard galaxies with known inclinations.

Check out the GUI first and then if you are interested Sign in and continue.

Everyone can participate in this project. To continue, you can easily use your Google account. To identify you, we will receive your basic profile information from Google.

Workflow Statistics

Left panel shows the statistics of the sorted galaxies.The blue bar represents the total number of candidates in our catalog. The red column shows how many galaxies have at least one measurement. The yellow and green bars display the number of galaxies with at least 2 and 3 measurements, respectively, and so on. Right panel shows the number of sorted galaxies as a function of time (this includes all visits: practice, training, calibration, etc). The blue curve displays the contribution of everyone and the red one shows the contribution of amateurs.
