2015/10/13
Lujendra Ojha, the Georgia Tech Ph.D. candidate who led the study, first noticed these puzzling features in High Resolution Imagine Science Experiment (HiRISE) images returned by the MRO spacecraft as...
We report the spectroscopic confirmation of a submillimeter galaxy (SMG) at z = 4.547 with an estimated LIR = (0.5-2.0) × 1013 L. The spectra, mid-IR, and X-ray properties indicate the bolometric lumi...
Spectroscopic Confirmation of Three z-Dropout Galaxies at z = 6.844 - 7.213: Lyman Alpha Demography of z ~ 7 Galaxies
