The detection and photometric redshift determination of distant galaxies using SIRTF ’s Infrared Array Camera
نویسنده
چکیده
We investigate the ability of the Space Infrared Telescope Facility ’s Infrared Array Camera to detect distant (z ∼ 3) galaxies and measure their photometric redshifts. Our analysis shows that changing the original long wavelength filter specifications provides significant improvements in performance in this and other areas. Subject headings: cosmology: early universe — galaxies: evolution — infrared: galaxies — instrumentation: photometers — techniques: photometric

The 1.6μm Bump as a Photometric Redshift Indicator
I describe the principle of using the 1.6μm H spectral feature as a photometric redshift indicator and demonstrate that the technique holds promise by successfully recovering the redshifts of a small sample of z=0–1 galaxies using only their infrared (JHKL) photometry. I then consider the applicability of the technique to the 3.6–8μm SIRTF filter set and investigate the systematic errors that c...
متن کاملOn Measuring the Infrared Luminosity of Distant Galaxies with the Space Infrared Telescope Facility
The Space Infrared Telescope Facility (SIRTF ) will revolutionize the study of dust–obscured star formation in distant galaxies. Although deep images from the Multiband Imaging Photometer for SIRTF (MIPS) will provide coverage at 24, 70, and 160μm, the bulk of MIPS–detected objects may only have accurate photometry in the shorter wavelength bands due to the confusion noise. Therefore, we have e...
متن کاملAn AzTEC 1.1-mm survey for ULIRGs in the field of the Galaxy Cluster
We have undertaken a deep (σ ∼ 1.1 mJy) 1.1-mm survey of the z = 0.54 cluster MS 0451.6−0305 using the AzTEC camera on the James Clerk Maxwell Telescope. We detect 36 sources with signal-to-noise ratio (S/N) ≥ 3.5 in the central 0.10 deg2 and present the AzTEC map, catalogue and number counts. We identify counterparts to 18 sources (50 per cent) using radio, mid-infrared, Spitzer InfraRed Array...
متن کاملProspects for future far - infrared / submillimeter studies of the high - redshift Universe
Observations made usingCOBE, SCUBA, ISO and MAMBO have provided a reasonable working knowledge of both the intensity of the submm and far-infrared background radiation and the source counts of luminous high-redshift dusty galaxies. However, because there are uncertainties in the background intensity determinations, the samples of detected galaxies are small, and most importantly, their redshift...
متن کاملComparing Chandra and Sirtf Observations for Obscured Starbursts and Agn at High Redshift
Tracking the star formation rate to high redshifts requires knowledge of the contribution from both optically visible and obscured sources. The dusty, optically-obscured galaxies can be located by X-ray and infrared surveys. To establish criteria for selecting such sources based only on X-ray and infrared surveys, we determine the ratio of infrared to X-ray brightness that would be observed by ...
