The Infrared Medium-deep Survey. VIII. Quasar Luminosity Function at
Yongjung Kim, Myungshin Im, Yiseul Jeon +27
Faint quasars with mag are known to be the potentially important contributors to the ultraviolet ionizing background in the post-reionization era. Howeve…
The Infrared Medium-deep Survey. \Romannum{7}. Faint Quasars at in the ELAIS-N1 Field
Suhyun Shin, Myungshin Im, Yongjung Kim +26
The intergalactic medium (IGM) at 5 to 6 is largely ionized, and yet the main source for the IGM ionization in the early universe is uncertain. Of the possible contributors…
On the observability of individual Population III stars and their stellar-mass black hole accretion disks through cluster caustic transits
Rogier A. Windhorst, M. Alpaslan, S. Andrews +44
Recent near-IR power-spectra and panchromatic Extragalactic Background Light measurements provide upper limits on the near-IR surface brightness (SB>31 mag/arcsec^2) that may come…
Analysis of the spatially-resolved -3.6m colors and dust extinction in 257 nearby NGC and IC galaxies
Duho Kim, Rolf A. Jansen, Rogier A. Windhorst +2
We present and analyze spatially-resolved maps for the observed - and -band to 3.6m flux ratios and the inferred dust extinction values, , for a sample of 257 nearby…
The Infrared Medium-deep Survey. VI. Discovery of Faint Quasars at with a Medium-band-based Approach
Yongjung Kim, Myungshin Im, Yiseul Jeon +25
The faint quasars with mag are known to hold the key to the determination of the ultraviolet emissivity for the cosmic re-ionization. But only a few have been identi…
The Infrared Medium-deep Survey. IV. Low Eddington Ratio of A Faint Quasar at : Not Every Supermassive Black Hole is Growing Fast in the Early Universe
Yongjung Kim, Myungshin Im, Yiseul Jeon +15
To date, most of the luminous quasars known at have been found to be in maximal accretion with the Eddington ratios, , suggesting enhanced nuclear activ…
On the observability of individual Population III stars and their stellar-mass black hole accretion disks through cluster caustic transits
Rogier A. Windhorst, F. X. Timmes, J. Stuart B. Wyithe +8
We summarize panchromatic Extragalactic Background Light data to place upper limits on the integrated near-infrared surface brightness (SB) that may come from Population III stars…
The Infrared Medium-deep Survey. III. Survey of Luminous Quasars at 4.7 z 5.4
Yiseul Jeon, Myungshin Im, Dohyeong Kim +21
We present our first results of the survey for high redshift quasars at . The search for quasars in this redshift range has been known to be challe…
Science Impacts of the SPHEREx All-Sky Optical to Near-Infrared Spectral Survey: Report of a Community Workshop Examining Extragalactic, Galactic, Stellar and Planetary Science
Olivier Doré, Michael W. Werner, Matt Ashby +65
SPHEREx is a proposed SMEX mission selected for Phase A. SPHEREx will carry out the first all-sky spectral survey and provide for every 6.2" pixel a spectra between 0.75 and 4.18 $…
Analysis of the Intrinsic Mid-Infrared L-band to Visible--Near-Infrared Flux Ratios in Spectral Synthesis Models of Composite Stellar Populations
Duho Kim, Rolf A. Jansen, Rogier A. Windhorst
We analyze the intrinsic flux ratios of various visible--near-infrared filters with respect to 3.5micron for simple and composite stellar populations, and their dependence on age,…
Optical-Near Infrared Color Gradients And Merging History Of Elliptical Galaxies
Duho Kim, Myungshin Im
It has been suggested that merging plays an important role in the formation and the evolution of elliptical galaxies(EGs). In order to understand the past merging history of EGs, w…
