Gaussian Representation Of Active Galactic Nuclei, Jeffrey W. Klimes, Matthew Lister Oct 2013

Gaussian Representation Of Active Galactic Nuclei, Jeffrey W. Klimes, Matthew Lister

The Summer Undergraduate Research Fellowship (SURF) Symposium

Active galactic nuclei (AGN) are the areas around the centers of galaxies with high luminosity in much of the electromagnetic spectrum. The existing model of AGN describes the high luminosity as the result of accretion of matter around a black hole at the galaxy’s center. Many AGN generate superluminal jets of density higher than the surrounding interstellar medium. The cause for and mechanics driving the relativistic jets are not well understood. In addition, the jets often change direction decaparsecs away from their associated cores, the cause of which has not been well explained. In order to better understand the mechanics …


Two Suns In The Sky: Stellar Multiplicity Influence On Planet Formation, Ji Wang, Debra Fischer Sep 2013

Two Suns In The Sky: Stellar Multiplicity Influence On Planet Formation, Ji Wang, Debra Fischer

Yale Day of Data

We found that a planet is less likely to exist around a binary star, and thus Tatooine may be just a dream.
