Past Events



Condensed and Living Matter Seminar: "A touch of non-linearity: mesoscale swimmers and active matter in fluids"

Daphne Klotsa (University of North Carolina)
- David Rittenhouse Laboratory, A4

Living matter, such as biological tissue, can be seen as a nonequilibrium hierarchical assembly of assemblies of smaller and smaller active components, where energy is consumed at many scales. The…



Astronomy seminar: "The Formation of Massive Galaxies: deep, high-redshift spectroscopy from the LEGA-C Survey and Beyond"

Rachel Bezanson (University of Pittsburgh)
- David Rittenhouse Laboratory, A6

Today’s massive elliptical galaxies are primarily red-and-dead, dispersion supported ellipticals. The physical process(es) driving the shutdown or “quenching” of star formation in these…



Physics and Astronomy Colloquium: "Dynamics of living flows"

Eleni Katifori (University of Pennsylvania)
- David Rittenhouse Laboratory, A8

Complex life larger than a humble nematode would not be possible without a circulatory system. Plants, fungi, and animals have developed vascular systems of striking complexity to solve problems of long…



Condensed and Living Matter Seminar: "Collective behavior underlying the mechanobiology of tissues"

Moumita Das (Rochester Institute of Technology)
- David Rittenhouse Laboratory, A4

Living cells and tissues are highly mechanically sensitive and active. Mechanical forces and stimuli influence the shape, motility, and functions of cells, modulate the behavior of tissues,…



Astronomy seminar: "Evidence for CII diffuse line emission at redshift z~2.6"

Shengqi Yang (New York University)
- David Rittenhouse Laboratory, A2

CII is one of the brightest emission lines from star-forming galaxies and is an excellent tracer for star formation. Recent work measured the CII emission line amplitude for redshifts 2<z<3.2…
