Deep Near-Infrared Universe Seen in the Subaru Deep Field
The Subaru Deep Field provides the currently deepest Kselected sample of high-z galaxies (K ′ ∼ 23.5 at 5σ). The SDF counts, colors, and size distributions in the near-infrared bands are carefully compared with pure-luminosity-evolution (PLE) as well as CDM-based hierarchical merging (HM) models. The very flat faint-end slope of the SDF K count indicates that the bulk (more than 90%) of cosmic ...
متن کاملProperties of Stars in the Subaru Deep Field
We investigate the properties of objects in the Subaru Deep Field (SDF), using public catalogs constructed from images in several optical passbands. Using a small subset of objects most likely to be stars, we construct a stellar locus in threedimensional color space. We then compare the position of all objects relative to this locus to create larger samples of stars in the SDF with rough spectr...
متن کاملbayesian analysis of zero-inflated count regression models and their application to analyzing the number of return to blood donation
background : to prepare safe and adequate blood supply to meet patients’ needs and ensure a sufficient number of regular blood donors, knowledge about factors encouraging people to donate blood regularly is essential. considering its importance, we aimed to identifying the effective factors of the return to blood donation in based on zero-inflated count regression models using bayesian approach...
متن کاملTHE [O ii]λ3727 LUMINOSITY FUNCTION AND STAR FORMATION RATE AT z ≈ 1.2 IN THE COSMOS 2 SQUARE-DEGREE FIELD AND THE SUBARU DEEP FIELD
We have carried out a wide-field imaging survey for [O ii]λ3727 emitting galaxies at z ≈ 1.2 in the HST COSMOS 2 square degree field using the Suprime-Cam on the Subaru Telescope. The survey covers a sky area of 6700 arcmin2 in the COSMOS field, and a redshift range between 1.17 and 1.20 (∆z = 0.03), corresponding to a survey volume of 5.56×105 Mpc3. We obtain a sample of 3176 [O ii] emitting g...
متن کاملSubaru telescope observations of Deep Impact.
The impact cratering process on a comet is controversial but holds the key for interpreting observations of the Deep Impact collision with comet 9P/Tempel 1. Mid-infrared data from the Cooled Mid-Infrared Camera and Spectrometer (COMICS) of the Subaru Telescope indicate that the large-scale dust plume ejected by the impact contained a large mass (approximately 10(6) kilograms) of dust and forme...
