Comparing the Near-infrared Spectral Energy Distributions from Different Stellar Population Synthesis Models with SPHEREx Observations
Jeong Hwan Lee, Minjin Kim, Woong-Seob Jeong +17
While stellar population synthesis (SPS) models have been widely used for spectral analysis in optical wavelengths, their characteristics remain uncertain in the near-infrared (NIR…
A UV-to-Near-infrared QSO Composite Spectrum from the SPHEREx All-Sky Survey
Minjin Kim, Yongjung Kim, Woong-Seob Jeong +19
We present a composite spectrum of type 1 SDSS QSOs (median ), constructed using SPHEREx spectrophotometric data and covering a rest-frame wavelength…
The SPHEREx Ices Investigation: An Overview
Gary J. Melnick, Joseph L. Hora, Matthew L. N. Ashby +26
SPHEREx is a NASA mission designed to perform an all-sky spectroscopic survey in the 0.75 - 5 m wavelength range. Its primary science objectives are to investigate: (1) inflatio…
SPHEREx mapping of diffuse PAH and H II emission in the Galactic plane
Giulia Murgia, Ari J. Cukierman, Brandon S. Hensley +29
We present preliminary SPHEREx maps of diffuse Galactic emission tracing polycyclic aromatic hydrocarbons (PAHs) and ionized hydrogen gas, and we study their relationship across th…
The Redshifts from 122 Bands: Comparative Redshift Forecast for Low-Resolution Spectra from SPHEREx and 7-Dimensional Sky Survey (7DS)
Jangho Bae, Bomee Lee, Myungshin Im +21
The recently initiated SPHEREx and 7DS surveys will deliver low-resolution spectra () for hundreds of millions of galaxies over the optical to near-infrared range…
Mapping the Galaxy Color-Star Formation Rate Relation with Manifold Learning and Infrared Image Stacking
Yu-Heng Lin, Daniel Masters, Andreas L. Faisst +7
Modern surveys present us with billions of faint galaxies for which we only have broadband images in 6-8 optical-to-near-infrared (NIR) filters. Galaxy star formation rates (…
Simulating Spectral Confusion in SPHEREx Photometry and Redshifts
Zhaoyu Huai, James J. Bock, Yun-Ting Cheng +12
We model the impact of source confusion on photometry and the resulting spectrophotometric redshifts for SPHEREx, a NASA Medium-Class Explorer that is carrying out an all-sky near-…
Parallel Application of Slitless Spectroscopy to Analyze Galaxy Evolution (PASSAGE): Survey Overview
Matthew A. Malkan, Vihang Mehta, Ayan Acharyya +49
During the second half of Cycle 1 of the James Webb Space Telescope (JWST), we conducted the Parallel Application of Slitless Spectroscopy to Analyze Galaxy Evolution (PASSAGE) pro…
Joint Survey Processing. III. Compact Oddballs in the COSMOS Field -- Little Red Dots and Transients
Yu-Heng Lin, Andreas L. Faisst, Ranga-Ram Chary +7
We present the HST ACS G800L grism spectroscopy observation of the faint active galactic nuclei (AGN) candidates in the COSMOS field at redshift of 6 selected by the point-source m…
The Potential of the SPHEREx Mission for Characterizing Polycyclic Aromatic Hydrocarbon 3.3 μm Emission in Nearby Galaxies
Edward Zhang, Andreas L. Faisst, Brendan Crill +18
Together with gas, stars, and supermassive black holes, dust is crucial in stellar and galaxy evolution. Hence, understanding galaxies' dust properties across cosmic time is critic…
