Physics with Antihydrogen Atoms

Colloquium | April 14 | 4:15-5:30 p.m. | LeConte Hall, Room #1


Joel Fajans, Professor of Physics, UC Berkeley

Department of Physics


Since trapping antihydrogen atoms, the ALPHA collaboration has begun to test fundamental symmetries with anti-atoms. In this talk I will present spectral measurements of an anti-atom (a test of CPT), a direct limit on matter-antimatter gravity with freefall type measurements (a test of the weak equivalence principle), and a precision charge neutrality test (a novel test of CPT.)



Total Lunar Eclipse

Special Event | April 14 | 11 p.m. |  Lawrence Hall of Science


Lawrence Hall of Science (LHS)


Look through astronomical telescopes at the Lawrence Hall of Science to observe the first total lunar eclipse for the Bay Area since 2011. The Lawrence Hall of Science's Planetarium and Science on a Sphere will teach visitors how eclipses work and what they look like from the ground... and even from space!   More >


Children, Faculty, Friends of the University, General Public

All Audiences

Because we will view the lunar eclipse, this event runs into the morning of April 15, until 1:30 a.m. Cost is $10 per person for general admission, $5 per person for Members.

The Illustris simulation: novel successes and remaining failures in modelling galaxy formation

Seminar: Cosmology Seminars | April 15 | 1:10 p.m. | B1 Hearst Field Annex


Shy Genel, CfA

Department of Astronomy


I will present first results from the Illustris simulation, which is a cosmological hydrodynamical simulation using 2*1820^3 resolution elements. The simulation follows thousands of massive galaxies down to z=0 inside a (100Mpc)^3 volume, resolving < ~kpc scales. It is run using the Arepo code to model gravity and hydrodynamics, as well as cooling, stellar population evolution, and various...   More >

Live Fast Die Young: The Evolution of Massive Stars towards their Death

Colloquium: Astronomy Colloquia | April 17 | 4:10 p.m. | 1 LeConte Hall


Selma de Mink, Carnegie Observatories

Department of Astronomy


Massive stars are rare and short-lived. Nevertheless, through their extreme brightness, strong outflows and powerful explosions, they heat and stir their surroundings, drive outflows on galactic scales, and are responsible for the main production heavy elements in the Universe. For this reason, stellar models of massive stars are an essential ingredient for a wide variety of astrophysical...   More >
