This is the Cosmicflows4 collaborative Inclination project. Your contribution to this project would be appreciated.
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 need to use your Google account. To identify you, we will receive your basic profile information from Google.
