K-DRIFT: Unveiling New Imagery of the Hidden Universe
Jongwan Ko, Woowon Byun, Kwang-Il Seon +31
Low-surface-brightness (LSB) structures play a crucial role in understanding galaxy evolution by providing significant insights into galaxy interactions, the histories of mass asse…
Analysis of the full Spitzer microlensing sample I: Dark remnant candidates and Gaia predictions
Krzysztof A. Rybicki, Yossi Shvartzvald, Jennifer C. Yee +70
In the pursuit of understanding the population of stellar remnants within the Milky Way, we analyze the sample of microlensing events observed by the Spitzer Space Teles…
Precision MARS Mass Reconstruction of Abell 2744: Synergizing the Largest Strong Lensing and Densest Weak Lensing Datasets from JWST
Sangjun Cha, Kim HyeongHan, Zachary P. Scofield +2
We present a new high-resolution free-form mass model of Abell 2744, combining both weak-lensing (WL) and strong-lensing (SL) datasets from JWST. The SL dataset comprises 286 multi…
Photometric Selection of Unobscured QSOs in the Ecliptic Poles: KMTNet in the South Field and Pan-STARRS in the North Field
Woowon Byun, Minjin Kim, Yun-Kyeong Sheen +18
We search for quasi-stellar objects (QSOs) in a wide area of the south ecliptic pole (SEP) field, which has been and will continue to be intensively explored through various space…
Dwarf Galaxy Discoveries from the KMTNet Supernova Program III. the Milky-Way Analog NGC~2997 Group
Tony Junjing Fan, Dae-Sik Moon, Hong Soo Park +8
We present the discovery of 48 new and the analysis of 55, including 7 previously discovered, dwarf galaxy candidates around the giant spiral galaxy NGC~2997 using deep image…
KMTNet Nearby Galaxy Survey: Overview and a Survey Description
Woowon Byun, Yun-Kyeong Sheen, Kwang-Il Seon +8
Recently, there has been an increasing demand for deep imaging surveys to investigate the history of the mass assembly of galaxies in detail by examining the remnants of mergers an…
