On unitary groups of crossed product von Neumann algebras
Yasuhito Hashiba
We consider the tracial crossed product algebra arising from a trace preserving action of a discrete group on a tracial von Neumann algebr…
On central sequence algebras of tensor product von Neumann algebras
Yasuhito Hashiba
We show that when are tracial von Neumann algebras with abelian, and commute in $(M\bar…
A 100-pc Scale, Fast and Dense Outflow in Narrow-Line Seyfert 1 Galaxy IRAS04576+0912
Toshihiro Kawaguchi, Shinobu Ozaki, Hajime Sugai +8
We report the initial result of an adaptive-optics assisted, optical integral-field-unit observation on IRAS04576+0912, the nearest (z=0.039) active galactic nucleus with a promine…
OISTER Optical and Near-Infrared Monitoring Observations of a Peculiar Radio-Loud Active Galactic Nucleus SDSS J110006.07+442144.3
Tomoki Morokuma, Masaomi Tanaka, Yasuyuki T. Tanaka +80
We present monitoring campaign observations at optical and near-infrared (NIR) wavelengths for a radio-loud active galactic nucleus (AGN) at z=0.840, SDSS~J110006.07+442144.3 (here…
Constraining supernova progenitors: an integral field spectroscopic survey of the explosion sites
H. Kuncarayakti, G. Aldering, J. P. Anderson +9
We describe a survey of nearby core-collapse supernova (SN) explosion sites using integral field spectroscopy (IFS) technique, which is an extension of the work described in Kuncar…
Integral field spectroscopy of supernova explosion sites: constraining mass and metallicity of the progenitors -- II. Type II-P and II-L supernovae
Hanindyo Kuncarayakti, Mamoru Doi, Greg Aldering +6
Thirteen explosion sites of type II-P and II-L supernovae in nearby galaxies have been observed using integral field spectroscopy, enabling both spatial and spectral study of the e…
Integral field spectroscopy of supernova explosion sites: constraining mass and metallicity of the progenitors - I. Type Ib and Ic supernovae
Hanindyo Kuncarayakti, Mamoru Doi, Greg Aldering +6
Integral field spectroscopy of 11 type-Ib/c supernova explosion sites in nearby galaxies has been obtained using UH88/SNIFS and Gemini-N/GMOS. The use of integral field spectroscop…
