Hi Redshift Wranglers! We want to learn more about who is interested in Redshift Wrangler, who our volunteers are, and how we can best support your contributions. Please take a few minutes to fill out our participant survey - your feedback will be so useful as we continue to grow and improve! Also note, this project recently migrated onto Zooniverse’s new architecture. For details, see here.
Help us use the light from distant galaxies to look back in time to the early universe!
Learn moreOur project involves two tasks we need your help with:
(1) You can "Identify Spectral Features" to help us find real emission and absorption lines in galaxy spectra that will help us measure the redshifts, and therefore distances, of galaxies! Task 1 Sandbox works through Task 1 with our DEIMOS data and provides simpler, less-noisy spectra to practice this task while you help us add classifications to an earlier dataset.
(2) You can also "Check Spectral Fits" to help us find any problems in the automated fits to the spectra that our computers perform once we know the redshift.
Note: Not all workflows may be available at all times.

Message from the researcher
They say that a picture is worth a thousand words, but in astronomy, a spectrum is worth a thousand pictures.
JeyhanAbout Redshift Wrangler
A galaxy's light can tell us a lot about its properties, but we have to make sense of the features and patterns in the lights' spectrum through spectroscopic analysis.
Every element in a galaxy (in its stars and gas) emits or absorbs light at certain specific wavelengths, or energies, and a spectrum shows us how much emission we detect from a galaxy at each wavelength. The spike (or dip) in intensity that occurs at a particular wavelength is called an emission line (or absorption line), and measuring these features can help us find out important characteristics of galaxies, like how they might be evolving and their distance from us.
We need your help to decipher the fingerprints of light from distant galaxies and uncover how they form, grow, and interact with each other throughout the history of our Universe!
