1. F175W and F275W photometry of M31 and M32
ID:
ivo://CDS.VizieR/J/ApJ/504/113
Title:
F175W and F275W photometry of M31 and M32
Short Name:
J/ApJ/504/113
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present Faint Object Camera (FOC) ultraviolet images of the central 14"x14" of Messier 31 and Messier 32. The hot stellar populations detected in the composite UV spectra of these nearby galaxies are partially resolved into individual stars, and their individual colors and apparent magnitudes are measured. We detect 433 stars in M31 and 138 stars in M32, down to detection limits m_F275W_=25.5mag and m_F175W_=24.5mag.
2. Galaxies in the Hubble Deep Field
ID:
ivo://CDS.VizieR/J/AJ/112/359
Title:
Galaxies in the Hubble Deep Field
Short Name:
J/AJ/112/359
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a catalog of morphological and color data for galaxies with 21<I_814<25mag in the Hubble Deep Field (Williams et al. 1996, in Science with the Hubble Space Telescope II). Galaxies have been inspected and (when possible) independently visually classified on the MDS and DDO systems. Measurements of central concentration and asymmetry are also included in the catalog. The fraction of interacting and merging objects is seen to be significantly higher in the Hubble Deep Field than it is among nearby galaxies. Barred spirals are essentially absent from the deep sample. The fraction of early-type galaxies in the Hubble Deep Field is similar to the fraction of early-types in the Shapley-Ames Catalog, but the fraction of galaxies resembling archetypal grand-design late-type spiral galaxies is dramatically lower in the distant HDF sample.
3. GOODS Morphological Catalog
ID:
ivo://CDS.VizieR/VII/246
Title:
GOODS Morphological Catalog
Short Name:
VII/246
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present below the morphological catalogs of galaxies in the GOODS North and South fields, as determined visually by R. S. Ellis with a magnitude limit from HST/ACS imaging of z<22.5 (AB).
4. HDF early-type and spiral galaxies
ID:
ivo://CDS.VizieR/J/ApJ/551/111
Title:
HDF early-type and spiral galaxies
Short Name:
J/ApJ/551/111
Date:
21 Oct 2021
Publisher:
CDS
Description:
We analyze the internal optical colors of a complete sample of I_814_<24mag early-type and spiral galaxies from the northern and southern Hubble Deep Fields (HDF). The subset of galaxies in the HDF-North are also investigated in the near-infrared using NICMOS photometry. We compare the central (inner 5% radius) colors of those spirals with clearly visible bulges with the integrated colors of ellipticals in our sample.
5. HDF-N spiral and irregular galaxies
ID:
ivo://CDS.VizieR/J/A+A/364/517
Title:
HDF-N spiral and irregular galaxies
Short Name:
J/A+A/364/517
Date:
21 Oct 2021
Publisher:
CDS
Description:
We analyze a morphologically-selected complete sample of 52 late-type (spiral and irregular) galaxies in the Hubble Deep Field North with total K-magnitudes brighter than K=20.47 and typical redshifts z~0.5 to 1.4. This sample exploits in particular the ultimate imaging quality achieved by HST in this field, allowing us to clearly disentangle the early- from late-type galaxy morphologies, based on accurate profiles of the surface brightness distributions.
6. HDF photometric redshifts catalog
ID:
ivo://CDS.VizieR/J/ApJ/513/34
Title:
HDF photometric redshifts catalog
Short Name:
J/ApJ/513/34
Date:
21 Oct 2021
Publisher:
CDS
Description:
Using the newly available infrared images of the Hubble Deep Field in the J, H, and K bands and an optimal photometric method, we have refined a technique to estimate the redshifts of 1067 galaxies. A detailed comparison of our results with the spectroscopic redshifts in those cases where the latter are available shows that this technique gives very good results for bright enough objects [AB(814nm)<26.0]. From a study of the distribution of residuals [{Delta}z_rms_/(1+z)~0.1 at all redshifts], we conclude that the observed errors are mainly due to cosmic variance. This very important result allows for the assessment of errors in quantities to be directly or indirectly measured from the catalog. We present some of the statistical properties of the ensemble of galaxies in the catalog, and we finish by presenting a list of bright high-redshift (z~5) candidates extracted from our catalog together with recent spectroscopic redshift determinations confirming that two of them are at z=5.34 and z=5.60.
7. HDF-South catalogue of galaxies
ID:
ivo://CDS.VizieR/J/A+AS/145/111
Title:
HDF-South catalogue of galaxies
Short Name:
J/A+AS/145/111
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a catalogue of galaxies in the HDF-S, created using the public version 1 images of the WFPC2 data. We created a catalogue with 4 pass-band (I(814), V(606), B(450), U(300). In V(606), B(450), U(300) and I(814), for each galaxy the catalogue gives photometric parameters. For the I(814), we estimated also the colours and for I(814)<26, the petrosian radius, the mean surface brightness within the petrosian radius, light concentration indexes, that is C_eta_ and C_abr_, and the asymmetry index as computed by Abraham software.
8. HDF-South NICMOS field
ID:
ivo://CDS.VizieR/J/ApJ/538/493
Title:
HDF-South NICMOS field
Short Name:
J/ApJ/538/493
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a catalog of photometry and photometric redshifts of 335 faint objects in the Hubble Deep Field South (HDF-S) near-infrared camera and multiobject spectrograph (NICMOS) field. The analysis is based on (1) infrared images obtained with the Hubble Space Telescope (HST) using the NICMOS with the F110W, F160W, and F222M filters; (2) an optical image obtained with HST using the Space Telescope Imaging Spectrograph with no filter; and (3) optical images obtained with the European Southern Observatory Very Large Telescope with U, B, V, R, and I filters. The primary utility of the catalog of photometric redshifts is as a survey of faint galaxies detected in the NICMOS F160W and F222M images. The sensitivity of the survey varies significantly with position, reaching a limiting depth of AB(1.6{mu}m)~28.7 and covering 1.01arcmin^2^ to AB(1.6{mu}m)=27 and 1.05arcmin^2^ to AB(1.6{mu}m)=26.5. The catalog of photometric redshifts identifies 21 galaxies (or 6% of the total) of redshift z>5, eight galaxies (or 2% of the total) of redshift z>10, and 11 galaxies (or 3% of the total) of best-fit spectral type E/S0, of which five galaxies (or 1% of the total) are of redshift z>1.
9. HDF-South WFPC2 observations
ID:
ivo://CDS.VizieR/J/AJ/120/2747
Title:
HDF-South WFPC2 observations
Short Name:
J/AJ/120/2747
Date:
21 Oct 2021
Publisher:
CDS
Description:
The Hubble Deep Field South (HDF-S) observations targeted a high Galactic latitude field near QSO J2233-606. We present Wide Field Planetary Camera 2 observations of the field in four wide bandpasses centered at roughly 300, 450, 606, and 814 nm. Observations, data reduction procedures, and noise properties of the final images are discussed in detail. A catalog of sources is presented, and the number counts and color distributions of the galaxies are compared with a new catalog of the original Hubble Deep Field (HDF-N) that has been constructed in an identical manner. The two fields are qualitatively similar, with the galaxy number counts for the two fields agreeing to within 20%. The HDF-S has more candidate Lyman break galaxies at z>2 than the HDF-N. The star formation rate per unit volume computed from the HDF-S, based on the UV luminosity of high-redshift candidates, is a factor of 1.9 higher than from the HDF-N at z~2.7, and a factor of 1.3 higher at z~4.
10. HDF-S: STIS imaging
ID:
ivo://CDS.VizieR/J/AJ/119/486
Title:
HDF-S: STIS imaging
Short Name:
J/AJ/119/486
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present the imaging observations made with the Space Telescope Imaging Spectrograph (STIS) of the Hubble Deep Field South. The field was imaged in four bandpasses: a clear CCD bandpass for 156ks, a long-pass filter for 22-25ks/pix typical exposure, a near-UV bandpass for 23ks, and a far-UV bandpass for 52ks. The clear, visible image is the deepest observation ever made in the UV-optical wavelength region, reaching a 10{sigma}AB magnitude of 29.4 for an object of area 0.2arcsec^2^. The field contains QSO J2233-606, the target of the STIS spectroscopy, and extends 50"x50" for the visible images, and 25"x25" for the ultraviolet images. We present the images, catalog of objects, and galaxy counts obtained in the field.
