Tomographer: End-to-end Redshift Distribution Estimation for Source Catalogs and Intensity Maps
Yi-Kuan Chiang, Yu Voon Ng, Yu-Ren Lin +2
Redshift information is central to nearly every extragalactic and cosmological application of sky surveys, yet only a small fraction of cataloged sources, and none of the photons f…
CIBER galaxy cross-correlations reveal a bright, low-redshift NIR background
Richard M. Feder, Grigory Heaton, James J. Bock +7
We perform the first tomographic analysis of near-IR extragalactic background light (EBL) anisotropies, cross-correlating CIBER 1.1 and 1.8 m imager data with photometric galaxy…
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…
Backlighting the Cosmic Web with Fast Radio Bursts: An Anthology of Dispersion Measure Cross-Correlations with Large-Scale Structure and Baryon Tracers
Kritti Sharma, Elisabeth Krause, Vikram Ravi +11
Fast Radio Bursts (FRBs) probe baryons permeating the cosmic web through their dispersion measures (DMs), which encode the integrated electron density along cosmological sightlines…
The SPHEREx Instrument: Calibration, testing and performance measurements of the NIR spectroscopic surveyor from the laboratory to in-orbit commissioning
Phil M. Korngut, James J. Bock, Samuel Condon +90
The SPHEREx near-infrared space telescope is an all-sky spectroscopic survey mission launched on March 12th, 2025 UTC. In addition to providing the community with a spectral databa…
SPHEREx Wide-Field Infrared Spectral Mapping of Interstellar Ices and Polycyclic Aromatic Hydrocarbons
Joseph L. Hora, Jinyoung K. Noh, Gary J. Melnick +32
We present some of the first infrared spectral maps acquired by SPHEREx. These maps, which to our knowledge are the largest of their type ever compiled in the near-infrared, reveal…
Spectral Map Making with SPHEREx
Ari J. Cukierman, Shuang-Shuang Chen, Jae Hwan Kang +24
We present map-making methodologies and preliminary spectral data cubes for SPHEREx, a NASA Explorer mission that launched in March 2025 and has been performing an all-sky near-inf…
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…
A Path to an All-Sky Survey with Roman
Jiwon Jesse Han, Anirudh Chiti, Kai-Feng Chen +93
A deep, space-based, all-sky near-infrared survey carried out with the Nancy Grace Roman Space Telescope would constitute a foundational astronomical infrastructure for decades to…
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.…
