The Washington Post talks to Jeyhan Kartaltepe, associate professor in RIT's School of Physics and Astronomy, and Rebecca Larson, postdoctoral research associate in RIT’s School of Physics and Astronomy, about images from the James Webb Space Telescope.

Astrophysicists using large radio telescopes to observe a collection of cosmic clocks in our galaxy have found evidence for gravitational waves that oscillate with periods of years to decades, according to a set of papers published Thursday in The Astrophysical Journal Letters.

According to scientists from across the globe—including those working on the project from RIT—this observing run by the LIGO-Virgo-KAGRA (LVK) collaboration features upgraded instruments, new and even more accurate signal models, and more advanced data analysis methods.

In collaboration with NASA, RIT unveiled a website asking for volunteers to join an effort to take critical measurements that will aid astronomers in identifying the “fingerprints” of different chemical elements present in galaxies and measuring their distances.

Associate Professor Jeyhan Kartaltepe has her hands full studying data from the most powerful observational instrument ever made, while continuing to bolster her reputation as a teacher and mentor. Her work has gotten the attention of the astronomy community worldwide.

Scientists from RIT, Caltech, Kwansei Gakuin University in Japan, and the Korea Astronomy and Space Science Institute will launch a rocket on Sunday for a short flight into space with the goal of resolving discrepancies about the sources of near-infrared light in the universe.

Tech Explorist features the first images from the largest program in the James Webb Space Telescope, COSMOS-Web, co-led by principal investigator Jeyhan Kartaltepe, associate professor in the School of Physics and Astronomy.

The first images from the largest program in the James Webb Space Telescope’s first year show many types of galaxies. Scientists from the COSMOS-Web program released mosaic images taken in early January by the telescope. COSMOS-Web, co-led by principal investigator Jeyhan Kartaltepe, aims to map the earliest structures of the universe.

Scientists on the hunt for a previously undetected type of gravitational waves believe they are getting close and have refined techniques to use in upcoming observational runs. Researchers from the LIGO-Virgo-KAGRA Collaboration outlined the most sensitive search to date for continuous gravitational waves from a promising source in a paper recently published in the Astrophysical Journal Letters.

New data from the James Webb Space Telescope (JWST) have revealed that the structures of galaxies in the early universe were much more diverse and mature than previously known. RIT Associate Professor Jeyhan Kartaltepe said that JWST’s ability to see faint high redshift galaxies in sharper detail than Hubble allowed the team of researchers to resolve more features and see a wide mix of galaxies.

By using radio telescopes to study sun-like stars in their death throes, scientists hope to reveal important information about the origin of life-enabling chemicals in the universe. The NSF is awarding a $339,362 grant to a team led by Professor Joel Kastner to conduct such a study.
