A Chain of Dark Clouds in Projection Against the Galactic Center
Takahiro Nagayama, Shuji Sato, Shogo Nishiyama +9
In the J, H, and Ks bands survey of the the Galactic Center region over an area of 2deg x 5deg, we have found many dark clouds, among which a distinguished chain of dark clouds can…
Magnetic Field Configuration at the Galactic Center Investigated by Wide Field Near-Infrared Polarimetry
Shogo Nishiyama, Motohide Tamura, Hirofumi Hatano +13
We present a polarimetric map of a 20'x20' area toward the Galactic center. The polarization of point sources has been measured in the J, H, and Ks bands using the near-infrared po…
Mapping dust column density in dark clouds by using NIR scattered light : Case of the Lupus 3 dark cloud
Yasushi Nakajima, Ryo Kandori, Motohide Tamura +3
We present a method of mapping dust column density in dark clouds by using near-infrared scattered light. Our observations of the Lupus 3 dark cloud indicate that there is a well d…
Sequential star formation in a cometary globule (BRC37) of IC1396
Hisashi Ikeda, Koji Sugitani, Makoto Watanabe +9
We have carried out near-IR/optical observations to examine star formation toward a bright-rimmed cometary globule (BRC37) facing the exciting star(s) of an HII region (IC1396) con…
Interstellar Extinction Law toward the Galactic Center II: V, J, H, and Ks Bands
Shogo Nishiyama, Tetsuya Nagata, Motohide Tamura +4
We have determined the ratios of total to selective extinction directly from observations in the optical V band and near-infrared J band toward the Galactic center. The OGLE (Optic…
Clustering of Emission-line Stars in the W5E HII region
Makoto Nakano, Koji Sugitani, Takahiro Niwa +2
We have made a new survey of emission-line stars in the W5E HII region to investigate the population of PMS stars near the OB stars by using the Wide Field Grism Spectrograph 2 (WF…
