First optical measurements
of Milky Way’s
Fermi Bubbles
probe their origin.

We have recently discoverd emission at high negative velocities above Galactic Center and in agreement with previously made ultra-violet absorption observations from the Hubble Space Telescope. These allow for new measurements to be made on the extreme conditions of gas influenced by the super massive black hole, Sgr A*, at the center of our Galaxy.

whampy: A new python Package to Access and Visualize WHAM Observations

The whampy package provides an easy way to load, view, and do science with the Wisconsin H-Alpha Mapper (WHAM) Sky Survey. It provides the following main features: (1) The ability to load the Sky Survey Data from the FITS table.  (2) The ability to quickly plot sections of the sky with beam maps. (3) The ability to calculate moment maps and arithmetic using the data

Anomalous Flaring of Warm Ionized Gas:
the Saggitarius-Carina Spiral Arm

Warm ionized gas is a diffuse component of the interstellar medium visiblle throughout the Galaxy with a large vertical extent. We found that the warm ionizedd gas has a consistent thickness for most of the Galaxy, but is several times puffier around the Saggitarius-Carina spiral arm, flaring as it moves to larger distances from the center of the Galaxy.
