The far-infrared to the millimeter region of the Electromagnetic Spectrum contains a wealth of information about the Universe at early epochs. Observations of cold gas and dust uniquely probe the earl...
2018年SPIE高能，光和红外天文探测器会议（SPIE High Energy,Optical,and Infrared Detectors for Astronomy VII）
2018年 SPIE 高能，光和红外天文探测器 会议
2017/11/27
High energy, optical, and infrared detectors are critical to the performance of astronomical observatories. Improvement in these detectors is critical to improving the sensitivity and quality of imagi...
Brightness and Fluctuation of the Mid-Infrared Sky from AKARI Observations towards the North Ecliptic Pole
Brightness Fluctuation Mid-Infrared Sky AKARI Observations the North Ecliptic Pole
2012/2/21
We present the smoothness of the mid-infrared sky from observations by the Japanese infrared astronomical satellite AKARI. AKARI monitored the north ecliptic pole (NEP) during its cold phase with nine...
Infrared and radio study of the W43 cluster: resolved binaries and non-thermal emission
Stars: binaries – Stars: Wolf-Rayet – X-rays: stars – Radio continuum: stars – Gamma rays: stars – Infrared: stars
2011/10/9
Context: The recent detection of very high-energy (VHE) gamma-ray emission from the direction of the W43 star-forming region prompted us to investigate its stellar population in detail in an attempt t...
The Mid-Infrared High-Ionization Lines from Active Galactic Nuclei and Star-Forming Galaxies
The Mid-Infrared High-Ionization Lines Active Galactic Nuclei Star-Forming Galaxies
2011/1/10
We used Spitzer/IRS spectroscopic data on 426 galaxies including quasars, Seyferts, LINER and HII galaxies to investigate the relationship among the mid-IR emission lines. There is a tight linear corr...
The Halo and Rings of the Planetary Nebula NGC 40 in the Mid-Infrared
the Planetary Nebula NGC 40 the Mid-Infrared
2011/1/10
We present imaging and spectroscopy of NGC 40 acquired using the Spitzer Space Telescope (Spitzer), and the Infrared Space observatory (ISO). These are used to investigate the nature of emission from ...
Near-Infrared Imaging Survey of Faint Companions around Young Dwarfs in the Pleiades Cluster
Near-Infrared Imaging Survey Faint Companions around Young Dwarfs
2011/1/10
We conducted a near-infrared imaging survey of 11 young dwarfs in the Pleiades cluster using the Subaru Telescope and the near-infrared coronagraph imager. We found 10 faint point sources, with magnit...
The energy budget for X-ray to infrared reprocessing in Compton-thin and Compton-thick active galaxies
The energy budget X-ray Compton-thin
2011/1/13
Heavily obscured active galactic nuclei (AGNs) play an important role in contributing to the cosmic X-ray background (CXRB). However, the AGNs found in deep X-ray surveys are often too weak to allow d...
The 1.6 micron near infrared nuclei of 3C radio galaxies: Jets, thermal emission or scattered light?

2011/1/11
Using HST NICMOS 2 observations we have measured 1.6-micron near infrared nuclear luminosities of 100 3CR radio galaxies with z<0.3, by modeling and subtracting the extended emission from the host gal...
