GECKO Follow-up Observation of the Binary Neutron Star-Black Hole Merger Candidate S230518h

Gregory S. H. Paek, Myungshin Im, Mankeun Jeong +12

The gravitational wave (GW) event S230518h is a potential binary neutron star-black hole merger (NSBH) event that was detected during engineering run 15 (ER15), which served as the…

Multiwavelength Afterglow Analysis of GRB 221009A: Unveiling the Evolution of a Cooling Break in a Wind-like Medium

Donggeun Tak, Z. Lucas Uhm, Gregory S. H. Paek +8

Gamma-ray bursts (GRBs) are the most energetic explosions in the universe, and their afterglow emission provides an opportunity to probe the physics of relativistic shock waves in…

Gravitational-wave Electromagnetic Counterpart Korean Observatory (GECKO): GECKO Follow-up Observation of GW190425

Gregory S. H. Paek, Myungshin Im, Joonho Kim +13

One of the keys to the success of multimessenger astronomy is the rapid identification of the electromagnetic wave counterpart, kilonova (KN), of the gravitational-wave (GW) event.…

The Early Light Curve of a Type Ia Supernova 2021hpr in NGC 3147: Progenitor Constraints with the Companion Interaction Model

Gu Lim, Myungshin Im, Gregory S. H. Paek +19

The progenitor system of Type Ia supernovae (SNe Ia) is expected to be a close binary system of a carbon/oxygen white dwarf (WD) and a non-degenerate star or another WD. Here, we p…

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…

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…
