- Description:
- For each WINGS galaxy with V absolute magnitude brighter than -16, the local density calculated as the Log (decimal) of the number of galaxies with M_V <= -19.5 per Mpc**2 is given. It is computed from the circular area enclosing the first 10 closest galaxies, plus the background counts expected from Berta et al. (2006). The Local Densities are also corrected for border effects. The Coverage field fraction are also given, both at CCDX, i.e. the fraction of the circular area of radius CCDX and centered in the X-ray center, which is included in the field of the CCD mosaics, and at CCDB (centered in the BCG). For clusters without velocity dispersion the distances are given in pixels and NOT in R200. These clusters are A311, A2665, A3164, and Z1261.

24702. WINGS morphology

- Title:
- WINGS morphology
- Short Name:

- Publisher:

- Description:
- The catalogue contains a total number of ~39 900 galaxies, for which we provide the automated estimates of the morphological type, applying the purposely devised tool MORPHOT to the V-band WINGS imaging. The used tool is non-parametric and fully empirical. In particular, MORPHOT exploits 21 morphological diagnostics, directly and easily computable from the galaxy image, to provide two independent classifications: one based on a maximum likelihood (ML), semi- analytical technique and the other one on a neural network (NN) machine. A suitably selected sample of ∼1000 visually classified WINGS galaxies is used to calibrate the diagnostics for theML estimator and as a training set in the NN machine. The final morphological estimator combines the two techniques. (http://adsabs.harvard.edu/abs/2012MNRAS.420..926F)

- 72 WINGS nearby clusters luminosity functions

- Description:
- Using V band photometry of the WINGS survey, we derive galaxy luminosity functions (LF) in nearby clusters. This sample is complete down to M_V_=-15.15, and it is homogeneous, thus facilitating the study of an unbiased sample of clusters with different characteristics. We constructed the photometric LF for 72 out of the original 76 WINGS clusters, excluding only those without a velocity dispersion estimate. For each cluster we obtained the LF for galaxies in a region of radius=0.5xr_200_, and fitted them with single and double Schechter's functions. We also derive the composite LF for the entire sample, and those pertaining to different morphological classes. Finally, we derive the spectroscopic cumulative LF for 2009 galaxies that are cluster members. The double Schechter fit parameters are correlated neither with the cluster velocity dispersion nor with the X-ray luminosity. Our median values of the Schechter's fit slope are, on average, in agreement with measurements of nearby clusters, but are less steep that those derived from large surveys, such as the SDSS. Early-type galaxies out number late-types at all magnitudes, but both early and late types contribute equally to the faint end of the LF. Finally, the spectroscopic LF is in excellent agreement with the one derived for A2199, A85 and Virgo, and with the photometric LF at the bright magnitudes (where both are available). There is a large spread in the LF of different clusters, however, this spread is not caused by correlation of the LF shape with cluster characteristics such as X-ray luminosity or velocity dispersions. The faint end is flatter than previously derived ({alpha}_f_=-1.7), which is at odds with that predicted from numerical simulations.

- Description:
- WINGS (WIde-field Nearby Galaxy-cluster Survey) is an all-sky (|b|>20) survey of a complete, X-ray selected sample of galaxy clusters in the redshift range 0.04-0.07. The core of the WINGS project is the optical (B,V) imaging survey. It provides photometric data for huge samples of galaxies (~550,000) and stars (~190,000) in the inner field (34'x34') of 77 nearby galaxy clusters.

- WINGS spectroscopy of 48 galaxy clusters
- Short Name:

- Date:

- Publisher:
- CDS
- Description:
- We present the results from a comprehensive spectroscopic survey of the WINGS (WIde-field Nearby Galaxy-cluster Survey) clusters, a program called WINGS-SPE. The WINGS-SPE sample consists of 48 clusters, 22 of which are in the southern sky and 26 in the north. The main goals of this spectroscopic survey are: (1) to study the dynamics and kinematics of the WINGS clusters and their constituent galaxies, (2) to explore the link between the spectral properties and the morphological evolution in different density environments and across a wide range of cluster X-ray luminosities and optical properties. We present redshift measurements for 6137 galaxies. The WINGS-SPE has a 30% overlap with previously published data sets, allowing us both to perform a complete comparison with the literature and to extend the catalogs. For each galaxy identifier, equatorial coordinates, redshift, errors, correlation factor and membership are given.

- Description:
- The WIde-field Nearby Galaxy clusters Survey (WINGS) is a project whose primary goal is to study the galaxy populations in clusters in the local universe, and of the influence of environment on their stellar populations. This survey has provided the astronomical community with a high quality set of photometric and spectroscopic data for 77 and 48 nearby galaxy clusters, respectively. We present the catalog containing the properties of galaxies observed by the wings spectroscopic survey, which were derived using stellar populations synthesis modelling approach. We also check the consistency of our results with other data in the literature. Using a spectrophotometric model that reproduces the main features of observed spectra by summing the theoretical spectra of simple stellar populations of different ages, we derive the stellar masses, star formation histories, average age and dust attenuation of galaxies in our sample. ~5300 spectra were analyzed with spectrophotometric techniques, and this allowed to derive the star formation history, stellar masses and ages, and extinction for the wings spectroscopic sample that we present in this paper. The comparison with the total mass values of the same galaxies derived by other authors based on sdss data, confirms the reliability of the adopted methods and data.

- Publisher:

- Description:
- The catalog gives the star formation history of WINGS galaxies, i.e. their metallicity (as the best fit metallicity obtained by running our code with 4 different values of global metallocity), the dust extinction (both total and from the youngest component), the star formation rate in four macro bins of age (i.e. 0-2e7; 2e7-6e8; 6e8-5.6e9; 5.6e9-17.8e9), three values of stellar mass (i.e. the mass of stars turned into stars globally, the mass in living stars + remnants and the mass in shining stars) both within the fiber and total. The total mass has been extrapolated from the data by rescaling the V flux to the one that we have from the photometry, i.e. assuming no color gradient from the aperture to the toal photometry. A color correction term has been then calculated using the color at 5 kpc and the calibration by Bell & deJong and is given as weel in the catalog. Finally we list the luminosity weighted age and the mass weighted age of our galaxies. (http://adsabs.harvard.edu/abs/2011A%26A...526A..45F)

- Title:
- WINGS V surface photometry
- Short Name:

- Date:

- Publisher:
- IA2
- Description:
- This catalog contains the surface brightness measurements of ~42250 galaxies detected in the V images of the WINGS cluster survey. For each galaxy V magnitude, mean surface brightness, effective radius, Sersic index and axial ratio are given, together with their errors. These global parameters were obtained by simultaneously fitting the major and minor axis light growth curves of galaxies with a 2D flattened Sersic-law, convolved by the appropriate, space-varying PSF, which was previously evaluated by the tool itself.
