Gauge-Theoretical Method in Solving Zero-curvature Equations II--Non-Weyl Class Solutions of the Static Einstein-Maxwell Equations
Takahiro Azuma, Takao Koikawa
The gauge-theoretical method introduced in our previous paper is applied to solve the axisymmetric and static Einstein-Maxwell equations. We obtain the solutions of the non-Weyl cl…
An ultra wide-band, high-sensitivity Q-band receiver for single-dish telescopes, eQ: rest frequency determination of CCS ( = -) and SO ( = -), and high-redshift CO ( = 1-0) detection
Fumitaka Nakamura, Chau-Ching Chiong, Kotomi Taniguchi +16
We report on the development and commissioning of a new Q-band receiver for the Nobeyama 45-m telescope, covering 30--50 GHz with a receiver noise temperature of about 15 K. We nam…
Gauge Theoretical Method in Solving Zero-curvature Equations I. -- Application to the Static Einstein-Maxwell Equations with Magnetic Charge
Takahiro Azuma, Takao Koikawa
The inverse scattering problem is applied to 2-dimensional partial differential equations called soliton equations such as the KdV equation and so on. It is also used to integrate…
Chemical Differentiation around Five Massive Protostars Revealed by ALMA -Carbon-Chain Species, Oxygen-/Nitrogen-Bearing Complex Organic Molecules-
Kotomi Taniguchi, Liton Majumdar, Paola Caselli +9
We present Atacama Large Millimeter/submillimeter Array Band 3 data toward five massive young stellar objects (MYSOs), and investigate relationships between unsaturated carbon-chai…
Smart Dimming Sunglasses for Photophobia Using Spatial Light Modulator
Xiaodan Hu, Yan Zhang, Hideaki Uchiyama +3
We present a smart sunglasses system engineered to assist individuals experiencing photophobia, particularly those highly sensitive to light intensity. The system integrates a high…
CARMA-NRO Orion Survey: unbiased survey of dense cores and core mass functions in Orion A
Hideaki Takemura, Fumitaka Nakamura, Héctor G. Arce +15
The mass distribution of dense cores is a potential key to understand the process of star formation. Applying dendrogram analysis to the CARMA-NRO Orion CO (=1--0) data,…
