Publisher:
NASA/IPAC Infrared Science Archive
Description:
The Cluster Lensing And Supernova survey with Hubble (CLASH) is an HST Multi-Cycle Treasury program (PI: Marc Postman) to survey 25 massive galaxy clusters at 16 wavelengths spanning from the near-UV to the near-IR (Postman et al. (2012)). The full HST dataset and associated catalogs and gravitational lens models are available at MAST. A series of programs with Spitzer have covered all CLASH galaxy clusters with IRAC Channels 1 and 2 (3.6 and 4.5 micron). Several of the targets include Channels 3 and 4 (5.8 and 8 micron) data. Spitzer mosaics, catalogs, and PSF images are available at IRSA.

Space Telescope Science Institute Archive
Description:
By observing 25 massive galaxy clusters with HST's new panchromatic imaging capabilities (Wide-field Camera 3, WFC3, and the Advanced Camera for Surveys, ACS), CLASH will accomplish its four primary science goals: - Map, with unprecedented accuracy, the distribution of dark matter in galaxy clusters using strong and weak gravitational lensing; - Detect Type Ia supernovae out to redshift z ~ 2, allowing us to test the constancy of dark energy's repulsive force over time and look for any evolutionary effects in the supernovae themselves; - Detect and characterize some of the most distant galaxies yet discovered at z > 7 (when the Universe was younger than 800 million years old - or less than 6% of its current age); - Study the internal structure and evolution of the galaxies in and behind these clusters.

Title:
CO Galactic Plane Survey
Short Name:
CO
Date:

Publisher:
NASA/GSFC HEASARC
Description:
New large-scale CO surveys of the first and second Galactic quadrants and the nearby molecular cloud complexes in Orion and Taurus, obtained with the Harvard-Smithsonian Center for Astrophysics 1.2 m telescope, have been combined with 31 other surveys obtained over the past two decades with that instrument and a similar telescope on Cerro Tololo in Chile, to produce a new composite CO survey of the entire Milky Way. The survey consists of 488,000 spectra that Nyquist or beamwidth (1/8 deg) sample the entire Galactic plane over a strip 4 deg-10 deg wide in latitude, and beamwidth or 1/4 deg sample nearly all large local clouds at higher latitudes. Compared with the previous composite CO survey of Dame et al. (1987), the new survey has 16 times more spectra, up to 3.4 times higher angular resolution, and up to 10 times higher sensitivity per unit solid angle. <P> Users should be aware that both the angular resolution and the sensitivity varies from region to region in the velocity-integrated map. The component surveys were integrated individually using clipping or moment masking in order to display nearly all statistically significant emission but little noise above a level of ~1.5 K km/s. See the reference below and the <a href="https://lweb.cfa.harvard.edu/mmw/"> Millimeter-Wave Group site</a> for more details Provenance: Data taken by two nearly-identical 1.2 m telescopes in Cambridge, MA and on Cerro Tololo, Chile combined into a complete survey of the Milky Way with CO integrated over all velocities..

Title:
Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS)
Short Name:
CANDELS
Date:

Publisher:
Space Telescope Science Institute Archive
Description:
CANDELS is designed to document the first third of galactic evolution from z = 8 to 1.5 via deep imaging of more than 250,000 galaxies with WFC3/IR and ACS. It will also find the first Type Ia SNe beyond z greater than 1.5 and establish their accuracy as standard candles for cosmology. Five premier multi-wavelength sky regions are selected; each has multi-wavelength data from Spitzer and other facilities, and has extensive spectroscopy of the brighter galaxies. The use of five widely separated fields mitigates cosmic variance and yields statistically robust and complete samples of galaxies down to 109 solar masses out to z ~ 8.

Cosmic Background Explorer DIRBE Annual\ Average\ Map
Short Name:

Publisher:
NASA/GSFC HEASARC
Description:
The DIRBE Project Data Sets cover the whole sky and provide photometric data in 10 bands ranging in wavelength from 1.25 to 240 microns. SkyView has supported three maps: an early averaged map including including zodiacal and Galactic components (COBE DIRBE (OLD)), a more recent cleaner version of that data (COBE DIRBE/AAM) and a map with the zodaical light subtracted out (COBE DIRBE/ZSMA). The early data is no longer supported. Please contact us if you want access to these data. <P> Detailed descriptions of the DIRBE, the data processing, and the data products are given in an Explanatory Supplement. A Small Source Spectral Energy Distribution Browser can be used to assess the visibility of an unresolved or small extended source in the DIRBE data and see its spectral energy distribution. As noted in section 5.6.6 of the Explanatory Supplement, the DIRBE Time-ordered Data are required to derive definitive point source fluxes. <p> These maps provide an estimate of the infrared intensity at each pixel and wavelength band based on an interpolation of the observations made at various times at solar elongations close to 90&amp;#176;;. <P> These COBE DIRBE maps are a combination original ten band passes with the following wavelengths: <UL> <LI>Band 1 - 1.25 &amp;#181;;m <LI>Band 2 - 2.2 &amp;#181;;m <LI>Band 3 - 3.5 &amp;#181;;m <LI>Band 4 - 4.9 &amp;#181;;m <LI>Band 5 - 12 &amp;#181;;m <LI>Band 6 - 25 &amp;#181;;m <li>Band 7 - 60 &amp;#181;;m <li>Band 8 - 100 &amp;#181;;m <li>Band 9 - 140 &amp;#181;;m <li>Band 10 - 240 &amp;#181;;m </ul> <p> The default two dimensional array uses Band 8 (100 &amp;#181;;m). <P> The COBE DIRBE/Annual Average Maps (AAM) is the cumulative weighted average of the photometry. This average is calculated using the weighted number of observations from each Weekly Averaged Map ( WtNumObs from the Weekly Averaged Map) as the weight, such that annual_average =sum( weekly_average * weekly_weight )/ sum( weekly_weight ) <p> COBE DIRBE/Zodi-Subtracted Mission Average (ZSMA) Skymap represents the extra-Solar system sky brightness. It is the average residual map that results after the modelled interplanetary dust (IPD) signal is subtracted from each of the DIRBE Weekly Skymaps from the cryogenic mission. Individual weekly residual maps can be reconstructed from the data supplied in the DIRBE Sky and Zodi Atlas (DSZA). Provenance: COBE Team. This is a service of NASA HEASARC.

Title:
Cosmic Dawn
Short Name:
CosmicDawn
Date:
07 Apr 2023
Publisher:
NASA/IPAC Infrared Science Archive
Description:
Cosmic Dawn is a new infrared survey covering the three Euclid deep fields and four other Euclid calibration fields using Spitzer's Infrared Array Camera (IRAC). These new observations are combined with all relevant IRAC archival data of these fields in order to produce the deepest possible mosaics of these regions. In total, these observations represent nearly 11% of the total Spitzer mission time. The resulting mosaics cover a total of approximately 71.5 deg^2 in the 3.6 and 4.5 micron bands, and approximately 21.8 deg^2 in the 5.8 and 8 micron bands. They reach at least 24 AB magnitude in the 3.6 micron band and up to ~5 mag deeper in the deepest regions. The astrometry is tied to the Gaia astrometric reference system, and the typical astrometric uncertainty for sources with 16 < [3.6] < 19 is 0.15". The photometric calibration is in excellent agreement with previous WISE measurements. Given that the Spitzer Space Telescope has now been decommissioned these mosaics are likely to be the definitive reduction of these IRAC data. This survey therefore represents an essential first step in assembling multi-wavelength data on the Euclid deep fields which are set to become some of the premier fields for extragalactic astronomy in the 2020s.

40. Cygnus-X: A Spitzer Legacy Survey of the Cygnus-X Complex

Title:
Cygnus-X: A Spitzer Legacy Survey of the Cygnus-X Complex
Short Name:
Cygnus-X
Date:
27 Oct 2022 19:00:00
Publisher:
NASA/IPAC Infrared Science Archive
Description:
The Cygnus-X region is one of the brightest regions of the sky at all wavelengths and one of the richest known regions of star formation of the Galaxy. The goals of the Cygnus-X survey are to provide a detailed picture of the processes that govern the evolution of massive star forming complexes, to study star formation in the massive star forming complex environment, and to provide a rich sample of intermediate to high mass protostars spanning the full range of protostellar evolution. The project will also allow us to assess the role of feedback in a massive OB star/molecular cloud complex. The survey imaged a ~24 square degree region centered near 20:30:25, +40:00 (J2000). The IRAC images had a median coverage of 3x12s high dynamic range (HDR) frames, and the MIPS data were taken in fast scanning mode in the 24 and 70 μm bands.
