Vladimir Vassiliev and the gamma-ray telescope

UCLA Physics and Astronomy professor leads development of first-of-its-kind telescope for gamma-ray astronomy

Vladimir Vassiliev has served as principal investigator on this project since 2012, it is part of the Cherenkov Telescope Array project that will construct the world’s largest and most sensitive gamma-ray observatory with 118 telescopes.

This telescope, Schwarszchild Couder Telescope, will be the workhorse of the array. It has the ability to study gamma rays in the sky with 10 times better sensitivity than current telescopes. It will help give insight to extreme environments in the universe.

Palu Earthquake aftermath

UCLA study classifies Indonesia’s devastating 2018 earthquake as a rare ‘supershear’

Lingseng Meng, Physics and Geophysics professor, and a team of UCLA scientists have spent months analyzing the speed, timing, and extent of the Palu earthquake. They ultimately found that the earthquake was unusually fast, and they, thus, identified it as a supershear.

A supershear earthquake is one that creates seismic shear waves, a wave recognized by the rupture in the earth’s crust moving very fast along a fault, causing the up-and-down or side-to-side waves that shake the ground. This immense shaking ultimately caused the multitude of landslides and liquefactions. This research was done by measuring the delays between various seismic sensors.

Quasar Image

Two UCLA astronomers use split images to understand how fast the universe is expanding

Tommaso Treu, Physics and Astronomy professor, and Simon Birrer, a UCLA postdoctoral scholar, have used split images of quasars to understand the Hubble constant, a number that relates the distances to the redshifts of galaxies. This is a question that has been disputed for nearly a century by astronomers.

Treu and Birrer turned to quasars as a light source to measure that hasn’t been used in other science calculations. The team is continuing to search for more quasars to include their precision. Meanwhile their work has been published in Monthly Notices of the Royal Astronomical Society.

SPOTLIGHT

UCLA ranked #1 public university

UCLA was named #1 among U.S. public universities in two significant lists: the 2019 U.S. News & World Report “Best Colleges” rankings, and the Wall Street Journal/Times Higher Education survey.

Qualities highlighted by the publications include UCLA’s commitment to top-quality education, fostering a sense of community, and prioritizing inclusion. Click here to read the news announcements.

Student Spotlight: Research on seafloor has great implications for sea levels

Pine Island Glacier

Ken Zhao, a PhD candidate in the department of Atmospheric and Oceanic Sciences published phenomenal research in the Journal of Physical Oceanography. This research focuses on the effects of seafloor sills on melting glaciers.

Ultimately, the research may help scientists create a better approach to mitigate rising sea levels.

The DIYnamics school outreach program

Earth, Planetary, and Space Sciences (EPSS) professor Jon Aurnou leads the Simulated Planetary Interiors Laboratory or SPINLab, which studies how the rotation of planets shapes the flow of fluids in their atmospheres and cores.

Fun, hands-on experiments developed by SPINLab students and postdocs are visiting local middle and high schools to teach younger students how Earth’s rotation impacts our day-to-day weather.

Alumni Spotlight: Christopher Snead, EPSS

Earth, Planetary, and Space Sciences alumnus Christopher Snead (Ph.D. 2016) is continuing his passion for research with the Astromaterials Curation Facility at NASA’s Johnson Space Center.

“The research I conducted [at UCLA] on cosmic dust particles prepared me to participate in high-level decisions about how future samples will be collected, curated, and analyzed in a way that maximizes scientific yield,” he says.
