C. Rodriguez, G. B. Taylor, R. T. Zavala +3
We report on the discovery of a supermassive binary black hole system in the radio galaxy 0402+379, with a projected separation between the two black holes of just 7.3 pc. This is…
Constraining Disk Parameters of Be Stars using Narrowband H-alpha Interferometry with the NPOI
C. Tycner, G. C. Gilbreath, R. T. Zavala +7
Interferometric observations of two well-known Be stars, gamma Cas and phi Per, were collected and analyzed to determine the spatial characteristics of their circumstellar regions.…
