OGLE-2016-BLG-1190Lb: First Spitzer Bulge Planet Lies Near the Planet/Brown-Dwarf Boundary
Y. -H. Ryu, J. C. Yee, A. Udalski +106
We report the discovery of OGLE-2016-BLG-1190Lb, which is likely to be the first Spitzer microlensing planet in the Galactic bulge/bar, an assignation that can be confirmed by two…
OGLE-2015-BLG-1459L: The Challenges of Exo-Moon Microlensing
K. -H. Hwang, A. Udalski, I. A. Bond +57
We show that dense OGLE and KMTNet -band survey data require four bodies (sources plus lenses) to explain the microlensing light curve of OGLE-2015-BLG-1459. However, these can…
Kilonova from post-merger ejecta as an optical and near-infrared counterpart of GW170817
Masaomi Tanaka, Yousuke Utsumi, Paolo A. Mazzali +42
Recent detection of gravitational waves from a neutron star (NS) merger event GW170817 and identification of an electromagnetic counterpart provide a unique opportunity to study th…
J-GEM observations of an electromagnetic counterpart to the neutron star merger GW170817
Yousuke Utsumi, Masaomi Tanaka, Nozomu Tominaga +57
The first detected gravitational wave from a neutron star merger was GW170817. In this study, we present J-GEM follow-up observations of SSS17a, an electromagnetic counterpart of G…
Subaru Hyper Suprime-Cam Survey for An Optical Counterpart of GW170817
Nozomu Tominaga, Masaomi Tanaka, Tomoki Morokuma +31
We perform a -band survey for an optical counterpart of a binary neutron star coalescence GW170817 with Subaru/Hyper Suprime-Cam. Our untargeted transient search covers d…
A Challenge to Identify an Optical Counterpart of the Gravitational Wave Event GW151226 with Hyper Suprime-Cam
Yousuke Utsumi, Nozomu Tominaga, Masaomi Tanaka +15
We present the results of the detailed analysis of an optical imaging survey conducted using the Subaru / Hyper Suprime-Cam (HSC), which aims to identify an optical counterpart to…
