We report our optical and near-infrared imaging observations for
the gravitational wave event S190510g. We started our observations
about 7.5 hours after the alert.
We performed galaxy-targeted observations for 28 galaxies (see the
table below) selected from the GLADE catalog (Dalya et al. 2016)
in the probability skymap of S190510g using the following
telescopes and instruments.
- 50 cm MITSuME telescope at Akeno Observatory and a 3 color imager (g, Rc, Ic)
- 50 cm MITSuME telescope at Okayama Astrophysical Observatory and a 3 color imager (g, Rc, Ic)
- 55 cm SaCRA telescope at Saitama University and MuSaSHI (r, i, z)
- 61 cm Boller & Chivens telescope at Mt. John Observatory in New Zealand (B&C) and a three color imager Tripole5 (g, r, i)
- 91 cm Okayama Astrophysical Observatory NIR Wide$B!>(BField Camera, OAOWFC (J) (Yanagisawa, K., et al. 2016, Proc. SPIE, 9908, 99085D)
- 150 cm Kanata telescope at Higashi-Hiroshima Observatory and HONIR -- a 2 channel imager (Rc and H or J) (Akitaya et al. 2014, 9147, 91474O)
- 200 cm Nayuta telescope at Nishi-Harima Astronomical Observatory and Nishiharima Infrared Camera, NIC (J, H, Ks)
- 380 cm Seimei telescope at Okayama Observatory and optical-fiber integral field spectrograph, KOOLS-IFU
We found no apparent transient object in these galaxies to 5 sigma
limiting magnitudes listed below, except for a few marginal cases
that are being carefully investigated by spectroscopy. We will post
it if it is likely an actual transient.
