SDSS 0956+5128: A Broad-line Quasar with Extreme Velocity Offsets
Charles L. Steinhardt, Malte Schramm, John D. Silverman +8
We report on the discovery of a Type 1 quasar, SDSS 0956+5128, with a surprising combination of extreme velocity offsets. SDSS 0956+5128 is a broad-lined quasar exhibiting emission…
Spectral response of SPHEREx
Howard Hui, Jamie Bock, Samuel Condon +31
The Spectro Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) is conducting the first all-sky near infrared spectral survey spanning 0.…
A Method to Distinguish Quiescent and Dusty Star-forming Galaxies with Machine Learning
Charles L. Steinhardt, John R. Weaver, Jack Maxfield +5
Large photometric surveys provide a rich source of observations of quiescent galaxies, including a surprisingly large population at z>1. However, identifying large, but clean, samp…
Evolution of Gas, and Star Formation from z = 0 to 5
Nick Scoville, Andreas Faisst, John Weaver +20
ALMA observations of the long wavelength dust continuum are used to estimate the gas masses in a sample of 708 star-forming (SF) galaxies at z = 0.3 to 4.5. We determine the depend…
Observations of Atmospheric Helium and Oxygen with SPHEREx
Howard Hui, Chi Nguyen, Ryan Wills +20
We present measurements of near-infrared (NIR) terrestrial airglow produced by helium and oxygen in the exosphere as observed by SPHEREx. Using eight months of survey data obtained…
Predicting Future Space Near-IR Grism Surveys using the WFC3 Infrared Spectroscopic Parallels Survey
James W. Colbert, Harry Teplitz, Hakim Atek +13
We present near-infrared emission line counts and luminosity functions from the HST WFC3 Infrared Spectroscopic Parallels (WISP) program for 29 fields (0.037 deg^2) observed using…
