Dance of Lyman-alpha Photons -- Modeling Lyman Alpha Emitters Around the End of Reionization
Zheng Zheng
11:30am|Bloomberg Hall Astrophysics Library
Lyman Alpha Emitters (LAEs) are becoming an important probe of the reionization of the universe. To correctly interpret the observations of LAEs, the effect of resonant scattering of Lyman-alpha photons has to be accounted for. I will present...

(Massive) Black Hole X-ray Binaries
Roger Blandford
11:00am|Bloomberg Hall Astrophysics Library
Stellar mass black holes with stellar companions on circular orbits can become powerful X-ray sources when mass is transferred from the star to the hole. In this talk, inspired by recent observations of RE J1034 +396, I will consider what happens...

What do the Spectra Mean in MHD Turbulence?
Chi-kwan Chan
11:30am|Bloomberg Hall Astrophysics Library
Magnetohydrodynamic (MHD) turbulence is responsible for many important astrophysics problems. For example, in the Sun, small scale magnetic fields can self-organize and generate large scale fields; in accreting disks, magnetorotational instability...
