What makes red quasars red? Observational evidence for dust extinction from line ratio analysis
Dohyeong Kim, Myungshin Im
Red quasars are very red in the optical through near-infrared (NIR) wavelengths, which is possibly due to dust extinction in their host galaxies as expected in a scenario in which…
North Ecliptic Pole multi-wavelength survey : new optical data with Hyper Suprime-Cam and near-future prospects with eROSITA
Nagisa Oi, Hideo Matsuhara, Tomotsugu Goto +19
The AKARI North Ecliptic Pole (NEP) survey consists of two survey projects: NEP-Deep (0.5 sq.deg) and NEP-Wide (5.4 sq.deg), providing with tens of thousands of galaxies. A continu…
Spitzer Observations of the North Ecliptic Pole
H. Nayyeri, N. Ghotbi, A. Cooray +19
We present a photometric catalog for Spitzer Space Telescope warm mission observations of the North Ecliptic Pole (NEP; centered at , $\rm Decl.=66^d33^m38^s…
Overview of North Ecliptic Pole Deep multi-wavelength Survey (NEP-Deep)
H. Matsuhara, T. Wada, N. Oi +22
The recent updates of the North Ecliptic Pole deep (0.5~deg, NEP-Deep) multi-wavelength survey covering from X-ray to radio-wave is presented. The NEP-Deep provides us with sev…
Distance and properties of NGC 4993 as the host galaxy of a gravitational wave source, GW170817
Myungshin Im, Yongmin Yoon, Seong-Kook Lee +9
Recently, the optical counterpart of a gravitational wave source GW170817 has been identified in NGC 4993 galaxy. Together with evidence from observations in electromagnetic waves,…
The X-ray counterpart to the gravitational wave event GW 170817
E. Troja, L. Piro, H. van Eerten +31
A long-standing paradigm in astrophysics is that collisions- or mergers- of two neutron stars (NSs) form highly relativistic and collimated outflows (jets) powering gamma-ray burst…
