Multi-epoch Optical Images of IRC+10216 Tell About the Central Star And the Adjacent Environment
Hyosun Kim, Ho-Gyu Lee, Youichi Ohyama +5
Six images of IRC+10216 taken by the Hubble Space Telescope at three epochs in 2001, 2011, and 2016 are compared in the rest frame of the central carbon star. An accurate astrometr…
Dual AGN candidates with double-peaked [O III] lines matching that of confirmed dual AGNs
D. -C. Kim, Ilsang Yoon, A. S. Evans +3
We have performed a spectral decomposition to search for dual active galactic nuclei (DAGNs) in the Sloan Digital Sky Survey (SDSS) quasars with . Potential DAGN candidates…
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…
Extremely Metal-Poor Representatives Explored by the Subaru Survey (EMPRESS). I. A Successful Machine Learning Selection of Metal-Poor Galaxies and the Discovery of a Galaxy with M*<10^6 M_sun and 0.016 Z_sun
Takashi Kojima, Masami Ouchi, Michael Rauch +18
We have initiated a new survey for local extremely metal-poor galaxies (EMPGs) with Subaru/Hyper Suprime-Cam (HSC) large-area (~500 deg^2) optical images reaching a 5 sigma limit o…
Dual black hole associated with obscured and unobscured AGN: CXO J101527.2+625911
D. -C. Kim, E. Momjian, Ilsang Yoon +6
We report the results of an investigation to determine the nature of the offset active galactic nucleus (AGN) found in the source CXO J101527.2+625911. Hubble Space Telescope and C…
