Origin of the X-ray Broad Iron Spectral Feature in GRS 1915+105
Misaki Mizumoto, Ken Ebisawa, Masahiro Tsujimoto +1
The X-ray spectrum of GRS 1915+105 is known to have a ``broad iron spectral feature'' in the spectral hard state. Similar spectral features are often observed in Active Galactic Nu…
Variability of the X-ray Broad Iron Spectral Features in Active Galactic Nuclei and Black-hole Binaries
Misaki Mizumoto, Ken Ebisawa, Masahiro Tsujimoto +1
The "broad iron spectral features" are often seen in X-ray spectra of Active Galactic Nuclei (AGN) and black-hole binaries (BHB). These features may be explained either by the "rel…
Enrichment of r-process elements in dwarf spheroidal galaxies in chemo-dynamical evolution model
Yutaka Hirai, Yuhri Ishimaru, Takayuki R. Saitoh +3
The rapid neutron-capture process (r-process) is a major process to synthesize elements heavier than iron, but the astrophysical site(s) of r-process is not identified yet. Neutron…
JVLA S and X-band Polarimetry of the Merging Cluster Abell 2256
Takeaki Ozawa, Hiroyuki Nakanishi, Takuya Akahori +6
We report polarimetry results of a merging cluster of galaxies Abell 2256 with Karl G. Jansky Very Large Array (JVLA). We performed new observations with JVLA at S-band (2051-3947…
