Project Descriiption
Use the Radio Galaxy Zoo: LOFAR project to help find supermassive black holes at the centres of galaxies and galaxies where stars are forming.
Go to https://www.zooniverse.org/projects/chrismrp/radio-galaxy-zoo-lofar/classify (links to an external site) (Links to an external site.)
Select the “Tutorial” tab. For each galaxy, you may be asked to place a “+” marker inside a blue dashed ellipse if it seems to belong in the same radio region (shown by the yellow lines) as the main solid blue ellipse. If there do not seem to be any dashed ellipses that match the radio region of the solid ellipse, you can move on.
For some images, you will also be able to match the optical image (shown as the background) to the radio emission (shown by the yellow lines and blue ellipses). If you think you can identify a single point (‘counterpart’) on the optical image that is generating the radio emission, mark it with a pink “+”. If there does not seem to be an optical source, you can move on.
The tutorials will give you some feedback on how you are doing before you start. After completing the tutorial, analyze 5 different images. Take before and after screenshots of each image that show the image before you have identified the centres of the matching dashed ellipses and the optical counterpart.
What to Include in The Project Plan
Research radio emission from galaxies and talk about how you will use Zooniverse. What resources will you use to complete this project? (Remember to include Zooniverse.)
What to Include in your Project Submission
Include a single image, which is a collage of the images before and after you have associated the dashed ellipses and optical counterparts for each of your five images. You should have 5×2 images combined in your submission.
The answers to the below reflection questions for each of your images.
Any references you used.
Reflection Questions (maximum 500 Words)
What is the difference between the optical image in the background and the radio emission shown by the yellow lines?
How many dashed ellipses did you link to the main solid ellipse that is flagged as the primary source of radio emission?
What does matching a radio source to a galaxy tell us about that galaxy?
