Extremely high-velocity gas in the galaxy Arp 220, revealed with ammonia absorption lines

Shuro Takano Kouichiro Nakanishi Naomasa Nakai Toshiaki Takano

Publications of the Astronomical Society of Japan 57(5) 2005年 [査読有り]

We observed ammonia (J, K) = (1, 1), (2, 2), (3, 3), and (4, 4) transitions at a wavelength of 1.3 cm toward a prototypical ultraluminous infrared galaxy, Arp 220, with the Nobeyama 45-m radio telescope. We detected extremely wide absorption lines...

Observations of clouds with the newly developed cloud profiling FM-CW radar at 95 GHz

Toshiaki Takano Ken Ichi Akita Hiroshi Kubo Youhei Kawamura Hiroshi Kumagai Tamio Takamura Yuji Nakanishi Teruyuki Nakajima

Proceedings of SPIE - The International Society for Optical Engineering 5979 2005年 [査読有り]

We developed a low-power and high-sensitivity cloud profiling radar transmitting frequency modulated continuous wave (FM-CW) at 95 GHz for ground-based observations. Millimeter wave at 95 GHz is used to realize much higher sensitivity than lower f...

Ray-tracing Calculation of VHF Radio Waves Scattered by Field-aligned Irregularities Associated with Equatorial Plasma Bubbles

Hiroyuki Nakata Yoshiaki Akaike Yuichi Otsuka Toshiaki Takano Satoshi Ujigawa Ikuo Nagashima

IEEJ Transactions on Fundamentals and Materials 124(12) 1253-1254 2004年 [査読有り]

In order to explain the propagation of VHF radio waves for TV broadcasting transmitted from Southeast Asia associated with equatorial plasma bubbles, we have examined ray paths of the radio waves scattered by field-aligned irregularities in equato...

First observational results with the newly developed cloud profiling FM-CW radar at 95 GHz

Toshiaki Takano Yumiro Suga Kenichi Akita Youhei Kawamura Hiroshi Kumagai Tamio Takamura Yuji Nakanishi Teruyuki Nakajima

Proceedings of SPIE - The International Society for Optical Engineering 5235 517-524 2004年 [査読有り]

We developed a cloud profiling radar transmitting frequency-modulated continuous wave (FM-CW) at 95 GHz for ground-based observations. Millimeter wave at 95 GHz is used to realize high sensitivity to small cloud particles. An FM-CW type radar woul...

Broadband observations of propagation anomaly of VHF WavesTransmitted from oversea broadcasting stations

Toshiaki Takano Kurt Sakai Ikuo Nagashima Hiroyuki Nakata Hiroaki Akaike Satoshi Ujigawa Han Higasa Shin Shimakura

2004 Asia-Pacific Radio Science Conference - Proceedings 368-371 2004年 [査読有り]

Broadband spectra in VHF band are regularly observed in Chiba, Japan, to investigate anomaly of propagation of broadcasting waves from distant Asian broadcasting stations. TV broadcasting waves from China, Philippines, Thai, Malaysia, and so on ca...
