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…
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…
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…
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…
Do strong bars exhibit strong non-circular motions?
Taehyun Kim, Dimitri A. Gadotti, Yun Hee Lee +4
Galactic bars induce characteristic motions deviating from pure circular rotation, known as non-circular motions. As bars are non-axisymmetric structures, stronger bars are expecte…
Exploring Unobscured QSOs in the Southern Hemisphere with KS4
Yongjung Kim, Minjin Kim, Myungshin Im +7
We present a catalog of unobscured QSO candidates in the southern hemisphere from the early interim data of the KMTNet Synoptic Survey of Southern Sky (KS4). The KS4 data covers $\…
Red Type-1 Quasars after Cosmic Noon and Impact on -related Quasar Statistics
Yongjung Kim, Dohyeong Kim, Myungshin Im +1
Over the past decades, nearly a million quasars have been explored to shed light on the evolution of supermassive black holes and galaxies. The ultraviolet-to-optical spectra of ty…
Eddington Ratios of Dust-obscured Quasars at : Evidence Supporting Dust-obscured Quasars as Young Quasars
Dohyeong Kim, Yongjung Kim, Myungshin Im +4
Dust-obscured quasars have been suspected as the intermediate stage galaxies between merger-driven star-forming galaxies and unobscured quasars. This merger-driven galaxy evolution…
