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 1.6 micron near infrared nuclei of 3C radio galaxies: Jets, thermal emission or scattered light?
infrared nuclei 3C radio galaxies
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...
Deep Near-Infrared Survey of the Pipe Nebula II: Data, Methods, and Dust Extinction Maps
ISM clouds – infrared ISM –stars formation
2010/11/11
We present a new set of high resolution dust extinction maps of the nearby and essentially
starless Pipe Nebula molecular cloud. The maps were constructed from a concerted deep nearinfrared imaging s...
Comparison of AGN and Nuclear Starburst Activity in Seyfert 1 and 2 Galaxies over a Wide Luminosity Range Based on Near-infrared 2-4 micrometer Spectroscopy
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
We present near-infrared K- (1.9-2.5 micrometer) and L- (2.8-4.2 micrometer) band spectroscopy of 22 Seyfert nuclei. We use two methods to investigate the presence of nuclear starbursts.
AKARI observation of the fluctuation of the near-infrared background. I
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
We sought to detect fluctuations of brightness in the sky toward the north ecliptic pole (NEP) with the Japanese infrared astronomical satellite AKARI, at 2.4, 3.2, and 4.1 {\mu}m. The obtained circul...
