Faculty appointed leader of the Cosmic Evolution Survey
Kartaltepe will help lead more than 200 scientists worldwide studying distant galaxies
Rochester Institute of Technology’s Jeyhan Kartaltepe is assuming leadership of a team of more than 200 scientists worldwide collaborating to study how galaxies are influenced by both their fundamental physical properties and the environment that surrounds them. Kartaltepe, an assistant professor of physics and deputy director of the Laboratory for Multiwavelength Astrophysics, became one of three faculty appointed to the Cosmic Evolution Survey (COSMOS) leadership team in January.
The COSMOS collaboration uses most of the world’s major telescopes on the Earth and in space to study a large patch of sky about 16 times the size of the full moon. The researchers examine all the different wavelengths of light coming from more than 1 million galaxies in the same patch of sky in order to get a better idea of what is going on in and around galaxies and how they have evolved over time. Kartaltepe, who has been involved in the collaboration since she was a graduate student at the University of Hawai'i at Manoa, said she was honored to help lead the collaboration toward its next step.
“It’s exciting to be working on a project that’s been so close to my heart,” said Kartaltepe. “COSMOS will always be near and dear to me because I grew up in it and I know these people so well. There are so many new facilities that will be coming online and the field of astronomy is growing with access to all the new data, so it’s a good time to have a fresh change and new look at things.”
The COSMOS collaboration initially centered on observations from the Hubble Space Telescope but has grown in scope to include many different types of telescopes. In the near future, COSMOS scientists will be focusing much of their work on observations from the James Webb Space Telescope, the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile and the Karl G. Jansky Very Large Array in New Mexico.
Kartaltepe will co-lead the collaboration along with two other new heads: Caitlin Casey of the University of Texas at Austin and Vernesa Smolcic from the University of Zagreb. The leadership team focuses on writing new proposals and getting funding for the project, organizing annual collaboration meetings, coordinating papers being written by the collaboration and looking forward to the future.
