The Changing-look Phenomenon Accompanied by an Accretion Mode Transition in NGC 3786
Suyeon Son, Minjin Kim, Luis C. Ho +2
To reveal the physical origin of the changing-look (CL) phenomenon in NGC 3786, which transitioned from type 1.8/1.9 to type 1, we present an analysis of long-term spectral monitor…
A Catalog of Mid-infrared Variable Sources in the Ecliptic Poles
Minjin Kim, Suyeon Son, Shinyu Kim +4
We construct a catalog of mid-infrared (MIR) variable sources using the multi-epoch 3.6 (W1) and 4.5 m (W2) dataset from the Near-Earth Object Wide-field Infrared Survey Explore…
Mid-infrared Variability-based AGN Selection using the Multi-epoch Photometric Data from WISE
Shinyu Kim, Minjin Kim, Suyeon Son +1
We assess the systematics and efficiency of an AGN selection method based on mid-infrared (MIR) variability. To this end, we utilize various types of active and inactive galaxies f…
Asymmetric torus variability in active galactic nuclei driven by global brightening and dimming
Suyeon Son, Minjin Kim, Luis C. Ho
Temporal asymmetry in the flux variability of active galactic nuclei (AGNs) offers key insights into the physical mechanisms driving AGN variability. In this study, we investigated…
