SPHEREx 0.75 to 5 m Spectra for a Sequence of Nearby Brown Dwarfs
Zafar Rustamkulov, J. Kirkpatrick, Rachel Akeson +21
The SPHEREx all-sky survey has now measured the R40-100 infrared spectra of thousands of nearby brown dwarfs in the chemically rich 0.75-5 m range. The survey's wide spect…
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…
Searching for the Shortest-wavelength Aromatic Infrared Bands: No Evidence for the Predicted 1.05 m Polycyclic Aromatic Hydrocarbon Feature
Dennis Lee, Brandon S. Hensley, Tzu-Ching Chang +1
Polycyclic aromatic hydrocarbons (PAHs) are responsible for a variety of near- and mid-infrared spectral features in Galactic and extragalactic sources. A feature at 1.05 m aris…
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…
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.…
Optimized Observation Sequencing in Low-Earth Orbit with the SPHEREx Survey Planning Software
Sean Bryan, James Bock, Thomas Burk +23
SPHEREx is a NASA infrared astronomy mission that launched on March 12th, 2025 and is operating successfully in low-Earth orbit (LEO). The mission is currently observing the entire…
The End of the Road for Far-infrared Reddening Maps? Evidence for Reddening Errors Driven by Changes in PAH Abundance
Dennis Lee, Brandon S. Hensley, Tzu-Ching Chang +1
Accurate correction for extinction by Galactic dust is essential for studying the extragalactic sky. In the low-extinction regions of the Ursa Major molecular cloud complex, we dem…
A Fast Bayesian Method for Coherent Gravitational Wave Searches with Relative Astrometry
Benjamin Zhang, Kris Pardo, Yijun Wang +3
Using relative stellar astrometry for the detection of coherent gravitational wave sources is a promising method for the microhertz range, where no dedicated detectors currently ex…
