Constructing a Hydrogen Line Library for Lyα Emitters at Low Redshifts (z < 0.4): Estimating Dust Extinction and Assessing Paschen line Detectability with SPHEREx
Junho Song, Hyunmi Song, Hyunjin Shim
Hydrogen recombination lines, one of the strongest emission lines from star-forming galaxies, are used to probe the early Universe as indicators of star formation rates and ionizin…
Black Hole Properties of Type-1 Active Galactic Nuclei in the North Ecliptic Pole Wide Field: I. Mid-infrared Sources with Optical Counterparts
Dohyeong Kim, Myungshin Im, Hyunjin Shim +11
We present measurements of black hole (BH) properties of 861 Type-1 active galactic nuclei (AGNs) in the North Ecliptic Pole (NEP)-Wide field. These AGNs are detected in both optic…
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…
Green peas in the southern sky: Broad-band color selection and spectroscopic follow up
Yejin Jeong, Hyunjin Shim, Eunchong Kim +1
We present a systematic search for 1696 Green Pea (GP) galaxy candidates in the southern hemisphere selected from the Dark Energy Survey Data Release 2 (DES DR2) and provide prelim…
