Masking Algorithm for CCD Bleeding in Korea Microlensing Telescope Network Images
Jiseop Shin, Mankeun Jeong, Myungshin Im +3
Astronomical CCD images are often affected by bleeding from bright sources, producing column-aligned streaks that degrade source detection and photometry. We present a pixel-level…
KMTNet Synoptic Survey of Southern Sky III: The First Data Release
Seo-Won Chang, Myungshin Im, Mankeun Jeong +13
We present the first public data release (DR1) of the KMTNet Synoptic Survey of Southern Sky (KS4). This deep, wide-field imaging survey covers a southern footprint of -85$^{\circ}…
Photometric Redshift Forecast for 7-Dimensional Sky Survey
Eunhee Ko, Myungshin Im, Yujin Yang +3
We investigate the expected accuracy of redshifts that can be obtained using low-resolution spectroscopic (medium-band) data from the 7-Dimensional Sky Survey (7DS). By leveraging…
Test of Cosmic Web-feeding Model for Star Formation in Galaxy Clusters in the COSMOS Field
Eunhee Ko, Myungshin Im, Seong-Kook Lee +1
It is yet to be understood how large-scale environments influence star formation activity in galaxy clusters. One recently proposed mechanism is that galaxy clusters can remain sta…
Multi-Object Spectroscopy of Galaxy Clusters at in Ultra Deep Survey Field with Different Star-formation Properties and Large-scale Environments
Seong-Kook Lee, Myungshin Im, Bomi Park +3
While galaxy clusters are dominated by quiescent galaxies at local, they show a wide range in quiescent galaxy fraction (QF) at higher redshifts. Here, we present the discovery of…
The Infrared Medium-deep Survey. IX. Discovery of Two New Quasars and Space Density down to mag
Yongjung Kim, Myungshin Im, Yiseul Jeon +17
We present the result of the Infrared Medium-deep Survey (IMS) quasar survey, using the combination of the IMS near-infrared images and the Canada-France-Hawaii Telescope…
