Galaxy-Galaxy Blending in SPHEREx Survey Data
Kim Dachan, Hyunmi Song, Yigon Kim +8
The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) will provide all-sky spectral survey data covering optical to mid-infrared…
Possibility of using 3.3m PAH luminosity as a molecular gas mass estimator
Hyunjin Shim, Junhyun Baek, Dohyeong Kim +12
We present CO(1-0) observations of 50 star-forming galaxies at 0.01<z<0.35, for which 3.3m PAH emission flux or its upper limit is available. A scaling relation between 3.3$\,…
Resolved Stellar Mass Estimation of Nearby Late-type Galaxies for the SPHEREx Era: Dependence on Stellar Population Synthesis Models
Jeong Hwan Lee, Minjin Kim, Taehyun Kim +7
The upcoming all-sky infrared spectrophotometric SPHEREx mission is set to provide spatially resolved stellar mass maps of nearby galaxies, offering more detailed insights than int…
Accuracy of Stellar Mass-to-light Ratios of Nearby Galaxies in the Near-Infrared
Taehyun Kim, Minjin Kim, Luis C. Ho +12
Future satellite missions are expected to perform all-sky surveys, thus providing the entire sky near-infrared spectral data and consequently opening a new window to investigate th…
