Envisioning the next decade of Galactic Center science: a laboratory for the study of the physics and astrophysics of supermassive black holes
Tuan Do, Andrea Ghez, Jessica R. Lu +38
As the closest example of a galactic nucleus, the Galactic center (GC) presents an exquisite laboratory for learning about supermassive black holes (SMBH) and their environment. We…
NEOSurvey 1: Initial results from the Warm Spitzer Exploration Science Survey of Near Earth Object Properties
David E. Trilling, Michael Mommert, Joseph Hora +6
Near Earth Objects (NEOs) are small Solar System bodies whose orbits bring them close to the Earth's orbit. We are carrying out a Warm Spitzer Cycle 11 Exploration Science program…
Spitzer-IRS high resolution spectroscopy of the 12μm Seyfert galaxies: I. First results
Silvia Tommasin, Luigi Spinoglio, Matthew A. Malkan +3
The first high resolution Spitzer IRS 9-37um spectra of 29 Seyfert galaxies (about one quarter) of the 12um Active Galaxy Sample are presented and discussed. The high resolution sp…
ALMA observations of NGC 6334S I: Forming massive stars and cluster in subsonic and transonic filamentary clouds
Shanghuo Li, Qizhou Zhang, Hauyu Baobab Liu +11
We present Atacama Large Millimeter/submillimeter Array (ALMA) and Karl G. Jansky Very Large Array (JVLA) observations of the massive infrared dark cloud NGC 6334S (also known as I…
A Wide-field Near- and Mid-Infrared Census of Young Stars in NGC 6334
Sarah Willis, Massimo Marengo, Lori Allen +3
This paper presents a study of the rate and efficiency of star formation in the NGC 6334 star forming region. We obtained observations at J, H, and Ks taken with the NOAO Extremely…
Circumstellar Structure around Evolved Stars in the Cygnus-X Star Formation Region
Kathleen E. Kraemer, Joseph L. Hora, Michael P. Egan +15
We present observations of newly discovered 24 micron circumstellar structures detected with the Multiband Imaging Photometer for Spitzer (MIPS) around three evolved stars in the C…
ALMA observations of NGC 6334S. II. Subsonic and Transonic Narrow Filaments in a High-mass Star Formation Cloud
Shanghuo Li, Patricio Sanhueza, Chang Won Lee +22
We present a study of narrow filaments toward a massive infrared dark cloud, NGC 6334S, using the Atacama Large Millimeter/submillimeter Array (ALMA). Thirteen gas filaments are id…
Far-infrared Fine-Structure Line Diagnostics of Ultraluminous Infrared Galaxies
Duncan Farrah, Vianney Lebouteiller, Henrik Spoon +16
We present Herschel observations of six fine-structure lines in 25 Ultraluminous Infrared Galaxies at z<0.27. The lines, [O III]52, [N III]57, [O I]63, [N II]122, [O I]145, and [C…
The Science Case for an Extended Spitzer Mission
Jennifer C. Yee, Giovanni G. Fazio, Robert Benjamin +45
Although the final observations of the Spitzer Warm Mission are currently scheduled for March 2019, it can continue operations through the end of the decade with no loss of photome…
