The Luminosity, Accretion Disk, and Dust Team (LADDT) : combining UV, optical, and near infrared data for active galactic nuclei to look for a relation between the color of their accretion disks, the emission from their dust and their luminosity.
One of my students at Niles West had become interested in GRBs as we thought they were the results of mergers of black holes [but we learned this was wrong at an AAS plenary talk]. My student thought it was interesting that scientists could change their minds about how things worked.
To get the chance to work with astronomers and researchers in the field, to do authentic research, and to attend conventions and be immersed in astronomy is absolutely amazing for a high school science teacher.
In summary, this [AAS meeting] was amazing. For four straight days, if I'd thrown a rock I would have hit a scientist. Priceless.
