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…
Space Telescope and Optical Reverberation Mapping Project. XII. Broad-Line Region Modeling of NGC 5548
P. R. Williams, A. Pancoast, T. Treu +155
We present geometric and dynamical modeling of the broad line region for the multi-wavelength reverberation mapping campaign focused on NGC 5548 in 2014. The dataset includes photo…
High- Universe probed via Lensing by QSOs (HULQ) I. Number Estimates of QSO-QSO and QSO-Galaxy Lenses
Yoon Chan Taak, Myungshin Im
It is unclear how galaxies and their central supermassive black holes (SMBHs) co-evolve across cosmic time, especially for the non-local universe (). The High- Un…
Gemini Multi-Object Spectrograph Integral Field Unit Spectroscopy of the Double-peaked Broad Emission Line of a Red Active Galactic Nucleus
Dohyeong Kim, Myungshin Im, Minjin Kim +1
Galaxy mergers are expected to produce multiple supermassive black holes (SMBHs) in close-separation, but the detection of such SMBHs has been difficult. 2MASS J165939.7183436 i…
Star Formation Enhancement in Barred Disk Galaxies in Interacting Galaxy Clusters
Yongmin Yoon, Myungshin Im
A recent study shows that bars can be induced via interaction of galaxy clusters, but it has been unclear if the bar formation by the interaction between clusters is related to the…
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…
Space Telescope and Optical Reverberation Mapping Project. IX. Velocity-Delay Maps for Broad Emission Lines in NGC 5548
Keith Horne, G. De Rosa, B. M. Peterson +155
We report velocity-delay maps for prominent broad emission lines, Ly_alpha, CIV, HeII and H_beta, in the spectrum of NGC5548. The emission-line responses inhabit the interior of a…
Stellar Properties of the Host Galaxy of an Ultraluminous X-ray Source in NGC 5252
Minjin Kim, Kristhell M. López, Peter G. Jonker +2
An ultraluminous X-ray source (ULX) in NGC 5252 has been known as a strong candidate for an off-nuclear intermediate-mass black hole. We present near-infrared imaging data of the U…
