A grant to upgrade Simons Observatory
researching working in simons observatory

The Devlin lab are working on creating an extremely cold environment (nearly -460 degrees Fahrenheit) so that the new Simons Observatory can detect cosmic microwave background (CMB), the residual radiation left behind by the Big Bang. Work done at the High Bay is essential for keeping the project from falling further behind after shutdown delays.

A grant to upgrade Simons Observatory

Mark Devlin and colleagues have been awarded an NSF grant to upgrade the prominent observatory in the high Atacama Desert in Northern Chile.
The Big Bang at 75

Where did the cosmos come from? This question has long been part of human speculation, says Vijay Balasubramanian. Today, thanks to scientists like Ralph Alpher and George Gamow, we have a rough picture: Some 13 billion years ago, the universe was a hot, dense state that cooled as it expanded.

    • The Big Bang at 75

    Theoretical physicist Vijay Balasubramanian discusses the 75th anniversary of the alpha-beta-gamma paper, what we know—and don’t know—about the universe and the “very big gaps” left to discover.

    A view inside the SNO detector when filled with water. In the background, there are 9,000 photomultiplier tubes that detect photons and the acrylic vessel that (now) holds liquid scintillator. The ropes that crisscross on the outside hold it down when the scintillator is added to prevent it from floating upwards. The acrylic vessel is 12 m wide, about half the width of an Olympic-sized swimming pool. The detector is located in SNOLAB, a research facility located 2km underground near Sudbury, Canada.

    New insights into the mechanisms of tumor growth

    A team of researchers led by the School of Arts & Science’s Wei Guo characterize the molecular pathways that play a major role in tumorigenesis, findings that could lead to better diagnostic tools for cancer and new targeted therapies.

    Wormhole-like dynamics

    Theoretical physicists Vijay Balasubramanian and Jonathan Heckman of the School of Arts & Sciences speak with Penn Today to explain the implications of new research claiming to have observed wormhole-like teleportation on a quantum computer.
