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...
Infrared two-colour diagrams for AGB stars using AKARI, MSX, IRAS and NIR data
stars: AGB and post-AGB - circumstellar matter - infrared: stars - dust extinction - radiative transfer
2011/10/12
Using a revised version of the catalog of AGB stars by Suh & Kwon (2009), we present various infrared two-colour diagrams (2CDs) for 3003 O-rich, 1168 C-rich, 362 S-type and 35 silicate carbon stars i...
Star-forming Region Sh 2-233IR I. Deep NIR Observations toward the Embedded Stellar Clusters
Star-forming Sh 2-233IR Observations Embedded Stellar Clusters
2011/10/9
We observed the Sh 2-233IR (S233IR) region with better sensitivity in near-infrared than previous studies for this region. By applying statistical subtraction of the back- ground stars, we identified ...
Current studies of the peculiar velocity flow field in the Local Universe are limited by the lack of detection of galaxies behind the Milky Way. The contribution of the largely unknown mass distributi...
The Mass Distribution of the Great Attractor as Revealed by a Deep NIR Survey
Distribution Great Attractor Revealed Deep Survey
2011/9/28
This paper presents the analysis of a deep near-infrared J,H,Ks-imaging survey (37.5 sq deg) aimed at tracing the galaxy distribution of the Great Attractor (GA) in the Zone of Avoidance along the so-...
Unveiling the nature of IGR J17177-3656 with X-ray, NIR and Radio observations
accretion accretion disks – X-rays binaries – binaries
2011/8/24
We report on the first broad-band (1-200 keV) simultaneous Chandra-INTEGRAL observations of the recently discovered hard X-ray transient IGR J17177-3656 that took place on 2011, March 22, about two we...

We report on the first broad-band (1-200 keV) simultaneous Chandra-INTEGRAL observations of the recently discovered hard X-ray transient IGR J17177-3656 that took place on 2011, March 22, about two we...
An optical/NIR survey of globular clusters in early-type galaxies II. Ages of GC systems and the relation to galaxy morphology
globular clusters early-type galaxies II
2011/1/10
Context: Some photometric studies of extragalactic globular cluster (GC) systems using the optical and near-infrared colour combination have suggested the presence of a large fraction of intermediate-...
High Mass X-ray Binaries in the NIR : Orbital solutions of two highly obscured systems
High Mass X-ray Binaries；the NIR
2011/1/13
The maximum mass of a neutron star (NS) is poorly defined. Theoretical attempts to define this mass have thus far been unsuccessful. Observational results currently provide the only means of narrowing...
The Principal Parameters of Unstudied Open Clusters with NIR Observations
Principal Parameters of Unstudied Open Clusters NIR Observations
2010/11/15
We studied the principal parameters of some previously unstudied open star clusters using the JHK Near-IR photometry (2MASS survey). These clusters have been selected from the updated Catalogs of Dais...
An optical/NIR survey of globular clusters in early-type galaxies. I. Introduction and data reduction procedures

2010/12/24
The combination of optical and near-infrared (NIR) colours has the potential to break the age/metallicity degeneracy and offers a better metallicity sensitivity than optical colours alone.
