•Short-Term Variability

Artist Conception of Sgr A Black Hole
and Expanding “Plasma Blob”
The picture on
the left is a model, or an artist’s conception, of what Sagittarius A might
look like at high resolution.At the center is a black hole with it s disk and outer spiral arm
pattern.The white outline
depicts an exploding plasma blob over time. (Technical term “Plasma Blob” =
ionized gas)
The plot on the
right shows the flare detected in X-ray by the Chandra Space Telescope.The plot also shows the exploding
plasma blob’s expansion in the submillimeter, as seen by SHARC2.
This short-term
variability was done in conjunction with the long-term variability study of
the previous slide.
