Observations of a Compact (<1000 AU) MYSO Cluster with HST (2009)
Janet P. Simpson, Michael G. Burton, Angela S. Cotera, Edwin F. Erickson, Dean C. Hines, ...
Observations show that most, if not all, massive stars form in clusters. This combination of massive stars and clusters has led to the suggestions that massive stars form by coalescence after stellar...
First Spectroscopic Identification of Massive Young Stellar Objects in the Galactic Center (2009)
An, Deokkeun, RamÃrez, Solange V., Sellgren, Kris, Arendt, Richard G., Boogert, A. C. Adwin, Schultheis, Mathias, ...
We report the detection of several molecular gas-phase and ice absorption features in three photometrically-selected young stellar object (YSO) candidates in the central 280 pc of the Milky Way. Our...
Hubble Space Telescope NICMOS Polarization Observations of Three Edge-on Massive YSOs (2009)
Simpson, Janet P., Burton, Michael G., Colgan, Sean W. J., Cotera, Angela S., Erickson, Edwin F., Hines, Dean C., ...
Massive young stellar objects (YSOs), like low-mass YSOs, appear to be surrounded by optically thick envelopes and/or disks and have regions, often bipolar, that are seen in polarized scattered light...

Abstract. We have discovered hot stars within the central 40 parsecs of the Galactic center. They may at least partially ionize the thermal radio emission regions. A cluster of such stars in the...

We present Hubble Space Telescope near-infrared camera and multiobject spectrometer observations of the reection nebulosity associated with the T Tauri star HH 30. The images show the scattered-light...
Spitzer IRS Observations of the Galactic Center: Shocked Gas in the Radio Arc Bubble (2007)
Simpson, Janet P., Colgan, Sean W. J., Cotera, Angela S., Erickson, Edwin F., Hollenbach, David J., Kaufman, Michael J., ...
We present Spitzer IRS spectra (R ~600, 10 - 38 micron) of 38 positions in the Galactic Center (GC), all at the same Galactic longitude and spanning plus/minus 0.3 degrees in latitude. Our positions...
Liu, Wilson M., Meyer, Michael R., Cotera, Angela S., Young, Erick T.
We present an analysis of NICMOS observations of the embedded cluster associated with NGC 2024. An analysis of the cluster color-magnitude diagram (CMD) using the models of D'Antona & Mazzitelli...
The Initial Mass Function of Low-Mass Stars and Brown Dwarfs in Young Clusters (2000)
Luhman, K. L., Rieke, G. H., Young, Erick T., Cotera, Angela S., Chen, H., Rieke, Marcia J., ...
We have obtained images of the Trapezium Cluster (140" x 140"; 0.3 pc x 0.3 pc) with the Hubble Space Telescope Near-Infrared Camera and Multi-Object Spectrometer (NICMOS). Combining these data with...
