Discovery of A Faint Quasar at z~6 and Implications for Cosmic Reionization
Yongjung Kim, Myungshin Im, Yiseul Jeon +15
Recent studies suggest that faint active galactic nuclei may be responsible for the reionization of the universe. Confirmation of this scenario requires spectroscopic identificatio…
Accretion Rates of Red Quasars from the Hydrogen P line
Dohyeong Kim, Myungshin Im, Eilat Glikman +2
Red quasars are thought to be an intermediate population between merger-driven star-forming galaxies in dust-enshrouded phase and normal quasars. If so, they are expected to have h…
Rest-frame Optical Spectra and Black Hole Masses of 3<z<6 Quasars
Hyunsung David Jun, Myungshin Im, Hyung Mok Lee +11
We present the rest-frame optical spectral properties of 155 luminous quasars at 3.3<z<6.4 taken with the AKARI space telescope, including the first detection of H emission line…
The AKARI 2.5-5.0 Micron Spectral Atlas of Type-1 Active Galactic Nuclei: Black Hole Mass Estimator, Line Ratio, and Hot Dust Temperature
Dohyeong Kim, Myungshin Im, Ji Hoon Kim +11
We present 2.5-5.0 m spectra of 83 nearby () and bright (mag) type-1 active galactic nuclei (AGNs) taken with the Infrared Camera (IRC) on board $\it…
