Testing Diagnostics of Nuclear Activity and Star Formation in Galaxies at z>1
Jonathan R. Trump, Nicholas P. Konidaris, Guillermo Barro +9
We present some of the first science data with the new Keck/MOSFIRE instrument to test the effectiveness of different AGN/SF diagnostics at z~1.5. MOSFIRE spectra were obtained in…
New M, L, and T Dwarf Companions to Nearby Stars from the Wide-field Infrared Survey Explorer
Kevin L. Luhman, Nicholas P. Loutrel, Nicholas S. McCurdy +8
We present 11 candidate late-type companions to nearby stars identified with data from the Wide-field Infrared Survey Explorer (WISE) and the Two Micron All-Sky Survey (2MASS). Eig…
Performance of the HgCdTe Detector for MOSFIRE, an Imager and Multi-Object Spectrometer for Keck Observatory
Kristin R. Kulas, Ian S. McLean, Charles C. Steidel
MOSFIRE is a new multi-object near-infrared spectrometer for the Keck 1 telescope with a spectral resolving power of R 3500 for a 0.7" slit (2.9 pixels). The detector is a substrat…
Further Defining Spectral Type "Y" and Exploring the Low-mass End of the Field Brown Dwarf Mass Function
J. Davy Kirkpatrick, Christopher R. Gelino, Michael C. Cushing +12
We present the discovery of another seven Y dwarfs from the Wide-field Infrared Survey Explorer (WISE). Using these objects, as well as the first six WISE Y dwarf discoveries from…
Early Science with SOFIA, the Stratospheric Observatory for Infrared Astronomy
E. T. Young, E. E. Becklin, P. M. Marcum +38
The Stratospheric Observatory for Infrared Astronomy (SOFIA) is an airborne observatory consisting of a specially modified Boeing 747SP with a 2.7-m telescope, flying at altitudes…
A T8.5 Brown Dwarf Member of the Xi Ursae Majoris System
Edward L. Wright, M. F. Skrutskie, J. Davy Kirkpatrick +12
The Wide-field Infrared Survey Explorer has revealed a T8.5 brown dwarf (WISE J111838.70+312537.9) that exhibits common proper motion with a solar-neighborhood (8 pc) quadruple sta…
