Transformable Reflective Telescope for optical testing and education
Woojin Park, Soojong Pak, Geon Hee Kim +6
We propose and experimentally demonstrate the Transformable Reflective Telescope (TRT) Kit for educational purposes and for performing various optical tests with a single kit. The…
Development of Linear Astigmatism Free -- Three Mirror System (LAF-TMS)
Woojin Park, Seunghyuk Chang, Jae Hyuk Lim +10
We present the development of Linear Astigmatism Free - Three Mirror System (LAF-TMS). This is a prototype of an off-axis telescope that enables very wide field of view (FoV) infra…
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…
Development of SED Camera for Quasars in Early Universe (SQUEAN)
Sanghyuk Kim, Yiseul Jeon, Hye-In Lee +6
We describe the characteristics and performance of a camera system, Spectral energy distribution Camera for Quasars in Early Universe (SQUEAN). It was developed to measure SEDs of…
The Infrared Medium-Deep Survey. V. A New Selection Strategy for Quasars at z > 5 based on Medium-Band Observation with SQUEAN
Yiseul Jeon, Myungshin Im, Soojong Pak +5
Multiple color selection techniques have been successful in identifying quasars from wide-field broad-band imaging survey data. Among the quasars that have been discovered so far,…
Proto-Model of an Infrared Wide-Field Off-Axis Telescope
Sanghyuk Kim, Soojong Pak, Seunghyuk Chang +5
We develop a proto-model of an off-axis reflective telescope for infrared wide-field observations based on the design of Schwarzschild-Chang type telescope. With only two mirrors,…
