Upcoming Department Colloquia



Colloquium: Twenty-five Years of Science with Chandra

Hans Moritz Guenther (MIT Kavli Institute for Astrophysics and Space Research)
-

Chandra is one of NASA's "great observatories" and was launched in 1999. In this talk, I will review Chandra's history and instruments and show highlights from an absolutely astonishing 25 years of science…



Colloquium: Energetic Optimization During Cell Division

Michael Murrell (Yale University)
-

Living systems are driven far from thermodynamic equilibrium through the continuous consumption of ambient energy. This energy is invested in the formation of complex, internal macromolecular structures and diverse…



Colloquium: Dark Matter Searches and New Constraints from the LUX-ZEPLIN (LZ) Experiment

Carmen Carmona (Pennsylvania State University)
- David Rittenhouse Laboratory, A8

The existence of dark matter is strongly supported by an abundance of astrophysical and cosmological evidence, but has yet to be directly detected. Liquid Xe detectors have been a game changer in the field of dark…

Past Department Colloquia



Colloquium: Global Famine after Nuclear War

Alan Robock (Rutgers University)
- David Rittenhouse Laboratory, A8

The world as we know it could end any day as a result of an accidental nuclear war between the United States and Russia. The fires produced by attacks on cities and industrial areas would generate smoke that would…



Colloquium: Light, Quantum and Energy

Liang Wu (University of Pennsylvania)
- David Rittenhouse Laboratory, A8

The conventional device to convert light to electrical current uses two different kinds of doped silicon merged together known as pn junction or heterostructures. The current only flows one way in the pn junction due…



Colloquium: The Wide-angle View of Dark Matter in Nearby Galaxies

Robyn Sanderson (University of Pennsylvania)
- David Rittenhouse Laboratory, A8

The Gaia astrometric survey has delivered a detailed “close-up” of our Galaxy, the Milky Way, by measuring precise 3D positions and…



Colloquium: Theia: Illuminating Neutrinos with a New Kind of Detector

Josh Klein (University of Pennsylvania)
- David Rittenhouse Laboratory, A8


Primakoff Lecture: Deciphering the Higgs boson: insights and revelations a decade after the discovery

Andreas Hoecker (CERN)
- David Rittenhouse Laboratory, A8

The discovery of the Higgs boson by the ATLAS and CMS experiments at CERN’s Large Hadron Collider (LHC) marks a breakthrough in particle physics, and it stands with the greatest scientific discoveries of all time.…
