Research Interest

Multi-wavelength analysis of supernova remnants

 Recently, an analysis that combines two or more wavelength data (multi-wavelength analysis) has received much attention as an approach to understand complicated astronomical phenomena. This is an attempt to reveal an astronomical object from various aspects, because different physical processes can be studied at different wavelengths. For instance, the radio emission line at 2.6 mm wavelength can trace molecular hydrogen clouds (-263 K), whereas X-rays can reveal plasma at ten million K and/or synchrotron radiation from relativistic electrons.
 Supernova remnants (*1) are suitable targets for the multi-wavelength analysis because they are bright in almost all wavelengths (Fig.1). I am promoting studies that reveal the origin of cosmic-rays (100 years problem in modern astrophysics) by multiwavelength analysis.
