3D Distribution Map of HI Gas and Galaxies Around an Enormous Ly $α$ Nebula and Three QSOs at $z = 2.3$ Revealed by the HI Tomographic Mapping Technique

Shiro Mukae, Masami Ouchi, Zheng Cai +21

We present an IGM HI tomography map in a survey volume of $16 \times 19 \times 131 h^{- 3} comoving Mpc^{3}$ (cMpc $^{3}$ ) centered at MAMMOTH-1 nebula and three neighbouring…

Resolving the Internal Structure of Circum-Galactic Medium using Gravitationally Lensed Quasars

Suzuka Koyamada, Toru Misawa, Naohisa Inada +3

We study the internal structure of the Circum-Galactic Medium (CGM), using 29 spectra of 13 gravitationally lensed quasars with image separation angles of a few arcseconds, which c…

Optical Variability Properties of Mini-BAL and NAL Quasars

Takashi Horiuchi, Toru Misawa, Tomoki Morokuma +3

While narrow absorption lines (NALs) are relatively stable, broad absorption lines (BALs) and mini-BAL systems usually show violent time variability within a few years via a mechan…
