Sagittarius B1 -- A Patchwork of H II Regions and PhotoDissociation Regions
Janet P. Simpson, Sean W. J. Colgan, Angela S. Cotera +2
Sgr B1 is a luminous H II region in the Galactic Center immediately next to the massive star-forming giant molecular cloud Sgr B2 and apparently connected to it from their similar…
Hunting for Planetary Nebulae toward the Galactic Center
Jihye Hong, Janet P. Simpson, Deokkeun An +2
We present near-infrared (IR) spectra of two planetary nebula (PN) candidates in close lines of sight toward the Galactic center (GC) using the Gemini Near-Infrared Spectrograph (G…
SOFIA/FORCAST Galactic Center Legacy Survey: Overview
Matthew J. Hankins, Ryan M. Lau, James T. Radomski +12
The Galactic Center contains some of the most extreme conditions for star formation in our Galaxy as well as many other phenomena that are unique to this region. Given our relative…
SOFIA FIFI-LS Observations of Sgr B1: Ionization Structure and Sources of Excitation
Janet P. Simpson, Sean W. J. Colgan, Angela S. Cotera +2
The current paradigm of Galactic Center (GC) gas motions and star formation envisions sequential star formation in streams of gas as they pass near the supermassive black hole, Sgr…
Spitzer Infrared Spectrograph Observations of the Galactic Center: Quantifying the Extreme Ultraviolet/so ft X-ray fluxes
Janet P. Simpson
It has long been shown that the extreme ultraviolet spectrum of the ionizing stars of H II regions can be estimated by comparing the observed line emission to detailed models. In t…
Spitzer observations of extragalactic H II regions - III. NGC 6822 and the hot star, H II region connection
Robert H. Rubin, Janet P. Simpson, Sean W. J. Colgan +5
Using the short-high module of the Infrared Spectrograph on the Spitzer Space Telescope, we have measured the [S IV] 10.51, [Ne II] 12.81, [Ne III] 15.56, and [S III] 18.71-micron…
