As astronomers, at the Sloan Digital Sky Survey everything we do is based on collecting light from cosmic objects. SDSS is therefore pleased that in 2015 we are celebrating the International Year of Light, and we especially would like to point out the Cosmic Light Theme, supported by the IAU.
As a small contribution to this celebration, every month in 2015 SDSS will have a special post on here talking about the different ways we use light. Our first post, which will appear before the end of January will be about how we use light to study black holes, something which seems like a contradiction, but has taught us a lot!
This post will be updated to collect all the links as the year progresses:
- How SDSS Uses Light to Study the Darkest Objects in the Universe (black holes, by Coleman Krawczyk and Karen Masters for January).
- How SDSS Uses Light to Measure the Distances to Galaxies (ie. redshifts, by Karen Masters for February)
- How SDSS Uses Light to Understand Stars Inside and Out in the Kepler Field, by Jennifer Johnson for March
- How SDSS Uses Light to Explore the Invisible (Dark Matter, by Anne-Marie Weijmans for April)
- How SDSS Used Light to Make the Largest Ever Digital Image of the Night Sky (about the SDSS imaging survey and camera, by Karen Masters for May)
- How SDSS Uses Light to Find Rocks in Space (by Karen Masters for June)
- How SDSS Splits Light into a Rainbow for Science (ie. spectra and gratings, with bonus activity to make your own spectroscope, by Karen Masters for July)
- How SDSS Uses Light to Study the Most Abundant Element in the Universe (ie. studying hydrogen, by David Whelan, for August)
- IYL2015 – SDSS Plates (in Retirement), about an SDSS plate at an IYL2015 exhibit in Dresden (by Zach Pace, for September).
- How SDSS uses mysterious “missing” light to map the interstellar medium (by Gail Zasowski for October)
