Two KIPAC Tea TalksFOBOS InstrumentSpeaker: Kevin Bundy, UC Santa CruzLarge Scale Dynamo in a Primordial Accretion FlowWithout an existing large scale coherent magnetic field in the early Universe, Population III stars would likely rotate at or near break-up speed. Using results from hydrodynamic simulations, we find evidence helical turbulence with a dynamo number ...

Cosmology with the Lya forest: beyond two-point statistics, DESI instrumentationThe Lyman-alpha forest is currently the only probe of cosmology and the state of the intergalactic medium (IGM) between redshifts of z=2 and 6. Its higher-order clustering, specifically its three-point correlation function (3PCF), contains information that can help to constrain fluctuations in the ionizing background and temperature fields of the ...
Rate- and State-dependent Friction (RSF) equations are commonly used to describe the time-dependent frictional response of fault gouge to perturbations in sliding velocity. Among the better-known versions are the Aging and Slip laws for the evolution of state. Although the Slip law is more successful, neither can predict all the ...

When Liquids are Liquids or Maybe NotWe introduce systems of liquids trapped in non-equilibrium configurations by interfacial assemblies of nanoparticle surfactants (‘NPSs’). These constructs consist of aqueous threads, length ~10-100 cm and diameter ~100 m whose mechanical properties are determined by an interfacial NPS assembly 20 nm thick. The interfacial layer consists of nanoparticles and polymers ...
What makes candy hard or soft? Learn what happens when sugar is heated up and how temperature effects the outcome. Enjoy candy making workshops and learn how to make your own candy at home! The Oakland Youth Chorus will be joining us for their winter concert under the Planetarium with ...

The Dark Matter of Physics RapRap is the language of the youth. Science is a way to expand our understanding of the universe. As the Genius of the Wu Tang Clan, GZA’s proposes to combine these two disparate concepts into his anticipated album, Dark Matter. Some predict it will be corny, but a closer look at ...

Dwarfs: Failed Stars or Overachieving Planets?Giant planets can be up to 13 times the mass of Jupiter, while the least massive stars are about 80 times the mass of Jupiter. In between are objects called "brown dwarfs" - too massive to be called planets, but not massive enough to burn hydrogen and shine like stars. ...
