    Abstract In order to understand the formation and evolution of galaxies fully, it is important to study their three-dimensional gravitational potential for a large sample of galaxies. Since polar-ring galaxies (PRGs) provide useful laboratories for this investigation, we have started our detailed study of a sample of known PRGs by using the data set obtained by the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). During the course of this study, we have discovered a new PRG, identified as SDSS J095351.58+012036.1. Its photometric redshift is estimated as z ∼ 0.2. The polar ring structure in this PRG appears to be almost perpendicular to the disk of its host galaxy without any disturbed features. Therefore, this PRG will provide us with useful information on the formation of such an undisturbed polar structure. We discuss its photometric properties in detail.

    <jats:title>Abstract</jats:title> <jats:p>We present our ALMA Band 8 observations of a damped Ly$\alpha$ absorption (DLA) system at $z = 3.150$ observed in the spectrum of the quasar Q2233+131 at $z = 3.295$. The optical counterpart of this DLA has been identified and it shows a double-peaked Ly$\alpha$ emission line. Since one possible origin of DLAs at high redshift is an outflowing gas from star-forming galaxies, DLA 2233+131 provides a good laboratory to investigate the nature of high-z DLAs. Motivated by this, we have carried out ALMA band 8 observations to study the [C ii] line in this system. However, we do not detect any significant emission line in the observed pass bands. Instead, we have serendipitously found three submm continuum sources in the observed sky area. One appears to be the quasar Q2233+131 itself while the other two sources are newly identified submm galaxies (SMGs), called SMG1 and SMG2 in this paper. They are located at a separation of ${4{^{\prime \prime }_{. } }7}$ and ${8{^{\prime \prime }_{. } }1}$ from Q2233+131, respectively. Their 646 μm fluxes are $6.35\:$mJy and $6.43\:$mJy, respectively, being higher than that of Q2233+131, $3.62\:$mJy. Since these two SMGs are not detected in the optical images obtained with the Hubble Space Telescope and the Subaru Telescope, they have a very red spectral energy distribution. It is, therefore, suggested that they are high-redshift galaxies or very dusty galaxies at intermediate redshift, although we cannot rule out the possibility that they are optically very faint SMG analogs at low redshift. Follow-up observations will be necessary to explore the nature of this interesting region.</jats:p>

    In order to investigate both the dark age and the cosmic reionization in early universe, we aim to observe very young galaxies and active galactic nuclei at redshift z > 8 by using highly-redshifted hydrogen Lyman alpha emission. For this purpose, our team has been developing a new near infrared imager and spectrograph for the 8.2 m Subaru Telescope; MOIRCS = Multi Object Infrared Camera and Spectrograph. This instrument has been already completed and opened for open use observations. MOIRCS has a wide field of view, 4 arcmin x 7 arcmin. This is the widest IR camera for such 8m class telescopes so far. Taking account of very high image quality of the Subaru Telescope, MOIRCS must be the most powerful and efficient IR instrument around the world. In order to detect highly redshifted hydrogen Lyman alpha emission, we have made new NIR narrowband filters from 1.1 micron to 2.3 micron. These narrowband filters allow us to detect Lyman alpha emitters from z = 9 to 18. The most distant know Lyman alpha emitter is located at z = 6.96. This object was found by a narrowband filter survey in the optical window. The presence of such very young galaxies encourage us to make deep surveys for Lyman alpha emitters beyond z = 7. Our target fields are GOODS-North and GOODS-South (GOODS = Great Observatories Origins Deep Survey promoted by Hubble Space Telescope and NASA). These two fields have been imaged with the Advanced Camera for Surveys (ACS) on Hubble Space Telescope. Moreover, follow-up observations by many large telescope facilities at various wavelengths have been already made by now The Hubble Ultra Deep Field is also located in GOODS-South. Therefore, these fields are most promising fields for any NIR deep survey programs. We have already obtained very deep NIR broadband images of GOODS-North. We have also obtained optical multi-band filter images in GOODS-South. In the GOODS-South, very deep NIR images obtained with ISAAC on the 8.2m Very Large Telescope in Chile. Therefore, we are ready to make very deep imaging surveys with our new NIR narrowband filters with MOIRCS on the Subaru Telescope. Since the MOIRCS was ready for use since 2006, but many technical test observations were necessary to check the total performance. Therefore, we did not have any observing time to use our new NIR narrowband filters by this March. We are planning to use our new filters in the coming observation semester on the Subaru Telescope. Since MOIRCS is still the greatest NIR instrument, we hope that we will be able to find very high-redshift Lyman alpha emitters beyond z = 7 in near future.

    本研究課題の目的は、活動銀河核の電離ガス輝線領域について、その輝線の空間分布および速度分布を再現できる統一的的な電離輝線領域モデルの構築である。観測的に示唆されている、より内側の電離ガス雲による電離光子の遮蔽効果、衝撃波による電離、ダストによる減光などの全ての現象を考慮したモデルを目指している。 昨年度までに構築した狭電離輝線領域の二領域モデルについて、内側のガス雲によって電離光子が吸収され外側の電離ガス雲が影響される効果を調べた。観測されている高電離輝線の輝線強度を再現しうるガスにより連続光成分の変化を調べ、その連続光が外側のガスをどのように電離するかを確認した。外側の輝線強度の変化に応じて、さらに内側の輝線領域の物理状態を変化させて観測を再現するように調整してゆくため、再計算を何度も繰り返す必要があり、効率的な計算のためにはその部分の最適化を図る必用があることがわかった。既存の研究で同様の手法を取り入れている結果と比較したところ、同じモデルパラメータに対してほぼ同じ結果を得ることができた。 また、モデル計算と比較し得る高空間分解能、高波長分解能観測を平行して進めている。電離ガス雲を非常に高い波長分解能で速度構造として分解することが目的である。平成14年2月にハワイ・マウナケア山のすばる望遠鏡において高波長分解能分光器を用いてセイファート銀河の電離輝線領域の観測した。一晩の観測で4天体を観測することが出来た。現在詳細なデータ解析を行っているところである。いずれの天体においても、複雑な速度構造を検出できている。このうち、1天体については詳細な解析を行い、論文として投稿中である。 このほかに活動銀河核にかかわる研究として、活動銀河核の中間赤外線分光観測をすばる望遠鏡において行い、活動銀河核に存在すると考えられているダストトーラスの光学的厚みを測る研究を行った。現在データの解析作業を進めているところである。

    We have performed our 7 micron deep survey program made with Infrared Space Observatory (ISO) , the infrared camera of ISO (ISOCAM). We have found 15 sources above a 5 sigma_<rms> significance in a small selected area (3'x3') in the lockman HI hole. Among the 15 sources 14 objects have also been observed in the near infrared (NIR : -2 micron) . The majority of the 7 micron sources have NIR counterparts most of which are considered to be galaxies with intermediate redshifts.It is, however, infriguing that a few 7 micron sources have no NIR counterparts. There objects may be heavily reddened populations which have not been detected by existing optical and NIR deep surveys.
