The NAture of the Faint Far-Infrared Extragalactic Source Population: Optical/NIR and Radio Follow-Up Observationts of ISOPHOT Deep-Field Sources using the Keck, Subaru, and VLA Telescopes.
Keck Subaru
2014/12/26
In order to search for obscured objects at high redshifts, we have made deep far-infrared (FIR) deep survey in the Lockman Hole using ISOPHOT onboard ISO (Kawara et al. 1998, A&A, 336, L9). In this su...
Detection of an ultra-bright submillimeter galaxy in the Subaru/XMM-Newton Deep Field using AzTEC/ASTE
AzTEC ASTE
2014/12/22
We report the detection of an extremely bright ($\sim$34 mJy at 1100 $\mu$m and $\sim$73 mJy at 880 $\mu$m) submillimeter galaxy (SMG), AzTEC-ASTE-SXDF1100.001 (hereafter referred to as SXDF1100.001),...
Structure and Population of the NGC55 Stellar Halo from a Subaru/Suprime-Cam Survey
Population Stellar Halo Subaru Suprime-Cam Survey
2011/9/28
As part of our survey of galactic stellar halos, we investigate the structure and stellar populations of the northern outer part of the stellar halo in NGC55, a member galaxy of the Sculptor Group, us...
Subaru weak-lensing study of A2163: bimodal mass structure
Subaru weak-lensing bimodal structure
2011/9/26
We present a weak-lensing analysis of the merging cluster A2163 using Subaru/Suprime-Cam and CFHT/Mega-Cam data and discuss the dynamics of this cluster merger, based on complementary weak-lensing, X-...

2010/11/9
Context. Palomar 1 is a peculiar globular cluster (GC). It is the youngest Galactic GC and it has been tentatively associated to several of the substructures recently discovered in the Milky Way (MW),...
The Subaru Ly-alpha blob survey: A sample of 100 kpc Ly-alpha blobs at z=3
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
We present results of a survey for giant Ly-alpha nebulae (LABs) at z=3 with Subaru/Suprime-Cam. We obtained Ly-alpha imaging at z=3.09+-0.03 around the SSA22 protocluster and in several blank fields.

紫金山天文台获得日本SUBARU望远镜的观测时间
经过日本SUBARU望远镜时间分配委员会的评审，由紫金山天文台江治波研究员领衔申请的“大质量原恒星天体星周环境的研究”课题，近日获得了该望远镜的3天观测时间。
SUBARU望远镜是国际顶尖的地面光学/红外望远镜之一，自开始运行以来取得了大量的研究成果，每年收到大量的观测申请。其中仅有10%对外开放的时间分配给...
