Updated Analysis of a "Dark" Galaxy and its Blue Companion in the Virgo Cloud HI 1225+01
Y. Matsuoka, N. Ienaka, S. Oyabu +2
HI 1225+01 is an intergalactic gas cloud located on the outskirts of Virgo cluster. Its main components are two large clumps of comparable HI masses (M_HI ~ 10^9 Msun) separated by…
Polarization and Variation of Near-IR Light from Fermi/LAT gamma-ray Sources
Mai Fujiwara, Yoshiki Matsuoka, Nobuyuki Ienaka
We present the results of our follow-up observation program of gamma-ray sources detected by the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope. 26 blazars…
Extinction law in ultraluminous infrared galaxies at z ~ 1
T. Shimizu, K. Kawara, H. Sameshima +3
We analyze the multi-wavelength photometric and spectroscopic data of 12 ultraluminous infrared galaxies (ULIRGs) at z ~ 1 and compare them with models of stars and dust in order t…
Cosmic Optical Background: the View from Pioneer 10/11
Y. Matsuoka, N. Ienaka, K. Kawara +1
We present the new constraints on the cosmic optical background (COB) obtained from an analysis of the Pioneer 10/11 Imaging Photopolarimeter (IPP) data. After careful examination…
Supernova dust for the extinction law in a young infrared galaxy at z = 1
K. Kawara, H. Hirashita, T. Nozawa +6
We apply the supernova(SN) extinction curves to reproduce the observed properties of SST J1604+4304 which is a young infrared (IR) galaxy at z = 1. The SN extinction curves used in…
Stellar population and dust extinction in an ultraluminous infrared galaxy at z=1.135
K. Kawara, S. Oyabu, Y. Matsuoka +6
We present the detailed optical to far-infrared observations of SST J1604+4304, an ULIRG at z = 1.135. Analyzing the stellar absorption lines, namely, the CaII H & K and Balmer H l…
Ultraviolet Fe II emission in z ~ 2 quasars
Hiroaki Sameshima, Jose Maza, Yoshiki Matsuoka +6
We present spectra of six luminous quasars at z ~ 2, covering rest wavelengths 1600-3200 A. The fluxes of the UV Fe II emission lines and Mg II 2798 doublet, the line widths of Mg…
