Spectroscopic Confirmation Of An Extreme Starburst At Redshift 4.547
Peter Capak, C. L. Carilli, N. Lee +22
We report the spectroscopic confirmation of a sub-mm galaxy (SMG) at z=4.547 with an estimated L_IR=0.5-2.0x10^13 L_sun. The spectra, mid-IR, and X-ray properties indicate the bolo…
Discovery of an Optically-Faint Quasar at z=5.70 and Implications for the Faint End of the Quasar Luminosity Function
A. Mahabal, D. Stern, M. Bogosavljevic +2
We present observations of an optically-faint quasar, RD J114816.2+525339, discovered from deep multi-color observations of the field around the z = 6.42 quasar SDSS J1148+5251. Th…
Spitzer IRS Spectra of Optically Faint Infrared Sources with Weak Spectral Features
D. W. Weedman, B. T. Soifer, Lei Hao +15
Spectra have been obtained with the low-resolution modules of the Infrared Spectrograph (IRS) on the Spitzer Space Telescope (Spitzer) for 58 sources having f(24 micron) > 0.7…
The redshift and nature of AzTEC/COSMOS 1: A starburst galaxy at z=4.6
V. Smolcic, P. Capak, O. Ilbert +36
Based on broad/narrow-band photometry and Keck DEIMOS spectroscopy we report a redshift of z=4.64-0.08+0.06 for AzTEC/COSMOS 1, the brightest sub-mm galaxy in the AzTEC/COSMOS fiel…
Spectroscopy of the Supernova H0pe Host Galaxy at Redshift 1.78
M. Polletta, M. Nonino, B. Frye +42
Supernova (SN) H0pe was discovered as a new transient in James Webb Space Telescope (JWST) NIRCam images of the galaxy cluster PLCK G165.7+67.0 taken as part of the "Prime Extragal…
Morphologies of High Redshift, Dust Obscured Galaxies from Keck Laser Guide Star Adaptive Optics
J. Melbourne, V. Desai, Lee Armus +7
Spitzer MIPS images in the Bootes field of the NOAO Deep Wide-Field Survey have revealed a class of extremely dust obscured galaxy (DOG) at z~2. The DOGs are defined by very red op…
