Image of the sunwheel in the fall: five standing stones in field on sunny day, against cloudy blue sky and fall foliage.
"Astronomers mark the change of seasons as the moment when the sun crosses over the celestial equator from the northern hemisphere of the sky to the southern hemisphere. This year the exact minute of the autumnal equinox is 3:21 p.m. Eastern Daylight Time on Sept. 22. At that moment, fall begins in the Northern Hemisphere and spring in the Southern. On the day of the equinox, an observer located on Earth’s equator will see the sun pass directly overhead at local noon. It also marks the beginning of six months of daylight at the South Pole and six months of nighttime at the North Pole."

Abstract: 

The propagation and evolution of cold galactic winds in galactic haloes is crucial to galaxy formation models. However, modeling of this process in hydrodynamic simulations of galaxy formation is over-simplified owing to a lack of numerical resolution and often neglects critical physical processes such as hydrodynamic instabilities and thermal conduction. In this thesis, I propose an analytic model, Physically Evolved Winds (PhEW), that calculates the evolution of individual clouds moving supersonically through a uniform ambient medium. The model reproduces predictions from very high resolution cloud-crushing simulations that include isotropic thermal conduction over a wide range of physical conditions. I also describe the implementation of this model into cosmological hydrodynamic simulations of galaxy formation as a sub-grid prescription to model galactic winds more robustly both physically and numerically.
