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…
Diverse nuclear star-forming activities in the heart of NGC 253 resolved with ten-pc scale ALMA images
Ryo Ando, Kouichiro Nakanishi, Kotaro Kohno +13
We present an 8 pc x 5 pc resolution view of the central ~ 200 pc region of the nearby starburst galaxy NGC 253, based on ALMA Band 7 (λ ~ 0.85 mm or ν ~ 350 GHz) observations cove…
H intensity map of the repeating fast radio burst FRB 121102 host galaxy from Subaru/Kyoto 3DII AO-assisted optical integral-field spectroscopy
Mitsuru Kokubo, Kazuma Mitsuda, Hajime Sugai +8
We present the H intensity map of the host galaxy of the repeating fast radio burst FRB 121102 at a redshift of z=0.193 obtained with the AO-assisted Kyoto 3DII optical integral…
J-GEM Follow-Up Observations to Search for an Optical Counterpart of The First Gravitational Wave Source GW150914
Tomoki Morokuma, Masaomi Tanaka, Yuichiro Asakura +22
We present our optical follow-up observations to search for an electromagnetic counterpart of the first gravitational wave source GW150914 in the framework of the Japanese collabor…
Ionization Source of a Minor-axis Cloud in the Outer Halo of M82
K. Matsubayashi, H. Sugai, A. Shimono +8
The M82 `cap' is a gas cloud at a projected radius of 11.6 kpc along the minor axis of this well known superwind source. The cap has been detected in optical line emission and X-ra…
