Telescope control software and proto-model siderostat for the SDSS-V Local Volume Mapper
Hojae Ahn, Florian Briegel, Jimin Han +19
The fifth Sloan Digital Sky Survey (SDSS-V) Local Volume Mapper (LVM) is a wide-field integral field unit (IFU) survey that uses an array of four 160 mm fixed telescopes with sider…
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…
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…
Flight model characterization of the wide-field off-axis telescope for the MATS satellite
Woojin Park, Arvid Hammar, Soojong Pak +6
We present optical characterization, calibration, and performance tests of the Mesospheric Airglow/Aerosol Tomography Spectroscopy (MATS) satellite, which for the first time for a…
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…
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…
Intensive Monitoring Survey of Nearby Galaxies (IMSNG)
Myungshin Im, Changsu Choi, Sungyong Hwang +46
Intensive Monitoring Survey of Nearby Galaxies (IMSNG) is a high cadence observation program monitoring nearby galaxies with high probabilities of hosting supernovae (SNe). IMSNG a…
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. 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,…
Photometry Transformation from RGB Bayer Filter System to Johnson-Cousins BVR Filter System
Woojin Park, Soojong Pak, Hyunjin Shim +4
The RGB Bayer filter system consists of a mosaic of R, G, and B filters on the grid of the photo sensors which typical commercial DSLR (Digital Single Lens Reflex) cameras and CCD…
