A New Lecture-Tutorial for Teaching Interferometry to Astro 101 Students
Colin S. Wallace, Chase Hatcher, Timothy G. Chambers +3
The ground-breaking image of a black hole's event horizon, which captured the public's attention and imagination in April 2019, was captured using the power of interferometry: many…
A New Lecture-Tutorial for Teaching about Molecular Excitations and Synchrotron Radiation
Colin S. Wallace, Edward E. Prather, Seth D. Hornstein +3
Light and spectroscopy are among the most important and frequently taught topics in introductory, college-level, general education astronomy courses. This is due to the fact that t…
A near-IR variability study of the Galactic black hole: a red noise source with no detected periodicity
Tuan Do, Andrea M. Ghez, Mark R. Morris +5
We present the results of near-infrared (2 and 3 microns) monitoring of Sgr A*-IR with 1 min time sampling using the natural and laser guide star adaptive optics (LGS AO) system at…
A Disk of Young Stars at the Galactic Center as Determined by Individual Stellar Orbits
J. R. Lu, A. M. Ghez, S. D. Hornstein +3
We present new proper motions from the 10 m Keck telescopes for a puzzling population of massive, young stars located within 3.5" (0.14 pc) of the supermassive black hole at the Ga…
Results from an extensive simultaneous broadband campaign on the underluminous active nucleus M81*: further evidence for mass-scaling accretion in black holes
S. Markoff, M. Nowak, A. Young +13
We present the results of a broadband simultaneous campaign on the nearby low-luminosity active galactic nucleus M81*. From February through August 2005, we observed M81* five time…
An X-ray, IR, and Submillimeter Flare of Sagittarius A*
D. P. Marrone, F. K. Baganoff, M. R. Morris +14
Energetic flares are observed in the Galactic supermassive black hole Sagittarius A* from radio to X-ray wavelengths. On a few occasions, simultaneous flares have been detected in…
