Spatially-Resolved Spectroscopic Properties of Low-Redshift Star-Forming Galaxies

S.F.Sanchez, ARAA, submitted

Summary

I present here the additional material required to reproduce the figures included in the review entitled "Spatially-Resolved Spectroscopic Properties of Low-Redshift Star-Forming Galaxies", to be published in the Annual Review of Astronomy and Astrophysics.

In that review I report on the spatially-resolved spectroscopic properties of low-redshift star- forming galaxies (and their retired counter-parts), using results from the most recent Integral Field Spectroscopy galaxy surveys:

This compilation used publically available data, all processed using Pipe3D, to homogenize the results. Most of the datapructs are indeed publically avaiable:

However, to facilitate the replication of the figures and future comparisons I include here the processed files, just prepared to reproduce the trends observed and described in the review.

Additional Material

The additional material included in this page comprises:

(1) Properties of the compiled sample, including the name of the objects, the IFS Galaxy Survey from which the data are extracted, the redshift, R-band absolute magnitude, B-R color, effective radius in kpc (r-band), morphological type (following Walcher et al. 2014) and a flag indicating if they belong to the well resolved sample (1) or not (0).

From this table it is created Figure 20 of the manuscript:


(2) The files required to generate the figures, showing the main trends described in the review. All fitsfiles are found in here.

For Figures 1-8 and Fig. 10, those files corresponds to 2D maps comprising: (1) the density distributions shown in different figures along the article (tracing the main reported trends between parameters; and (2) the EW(Ha) at each location within the reported distributions. The 2D distributions are stored in fits that include in the header the WCS required to determine at which location in each diagram correspond each pixel.

Figure 11: Distribution of the Sigma_* along the time and radius
Radial distribution stored in SUBSAMPLE.p_e.rad_SFH_lum_Mass_C.fits.gz
Each of these files contains, averaged for each sub-sample, the radial distribution of Sigma_* (along the Y-axis) for different look-back times (along the X-axis) as recovered from the stellar population analysis performed by FIT3D. Thus, each vertical cut represents the radial distribution of Sigma_* at the each considered time, and each horizontal cut represents the growth with time of Sigma_* at a certain radius.

The Y-axis is normalized at the observed (present) effective radius Re, ranging from 0 to 3.5 R/Re, with steps of 0.1 R/Re for each pixel in the Y-axis.

The X-axis corresponds ages in logarith scale, starting at log(age/yr)=6.4, and spaning 0.1 dex for each pixel in the X-axis, up to 10.2 dex.

In Fig. 11 we show horizontal cuts average every 5 radial bins for clarity.

Figure 12 it is shown as an example:
SUBSAMPLE describe the galaxy morphologycal type included in each panel, in the following order:

ALLES0Sa
SbSbcScSd

E.g., for the 2nd panel there are used the files:

E_Mass_11_13.5.p_e.RAD_ALL.fits.gz (yellow line)
E_Mass_10.5_11.p_e.RAD_ALL.fits.gz (red line)
E_Mass_9.5_10.5.p_e.RAD_ALL.fits.gz (grey line)
E_Mass_7_9.5.p_e.RAD_ALL.fits.gz (blue line)

This files (*.p_e.RAD_ALL.fits.gz) are datacubes in which the radial distribution of each particular property of the galaxies is stored in each slice (or 2D image) along the Z-axis. The property stored in indicated in a header heyword, named DEC_NN where NN is the slice index along the Z-axis of the cube, starting with 0.
The relevant for this review were:
DESC_0 | Stellar mass density in logarithm of Msun/pc^2 (Fig. 12,17)
DESC_1 | SFR density in logarith of Msun/pc^2 (Fig. 16,17,19)
DESC_2 | Molecular gas mass density derived from Av in log. of Msun/pc^2 (Fig. 18,19)
DESC_4 | Lum. Weighted Stellar metallicity [Z/H] (Fig. 9 & Fig. 14)
DESC_6 | Lum. Weighted Stellar Ages in log of yr (Fig. 13)
DESC_9 | 12+log(O/H) derived using the Marino et al. 2013 O3N2 calibrator (Fig. 16)

The remaining parameters in the file were not used in this review, and in some cases are highly experimental.

In each slice, the X-axis corresponds to a different galactocentric distance, in units of the effective radius of each galaxy (prior to derive the average by galaxy group). Each pixel corresponds to 0.15 R/Re, ranging from 0 to 3.5Re.

Finally, for each slice, the values at each index in the Y-axis corresponds to: Y_0 | The galactocentric distance indicated before
Y_1 | mean value of the parameter in the slice (described by the keyword DESC_NN
Y_2 | The standard deviation for that parameter along all galaxies in the subsample
Y_3 | the median value
Y_4 | the minimum value within the sample of galaxies
Y_5 | the maximum value within the sample of galaxies
The latter to should not be used (when no value is covered for one galaxy, the reported value is absurd)
For each radial distribution shown along the review it is plotted the mean value (Y_1) plus/minus the standard deviation (Y_2) of the considered parameter (NN), along the galactocentric distance extracted from the Y_0 parameter.
Thus, for Fig. 12, it is shown the 2nd raw plus/minus the third row of the 1st slice in the Z-axis along the 1st raw of the same slice, for each cube corresponding to a different subsample.

Figure 9: Radial average distribution along the Sigma-[Z/H] diagram
It uses the same files as the radial gradients described before. However, in this case it shows the distribution of 2nd row plus/minus the 3rd row of the 5th slice (DESC_4 or NN=4) in the Z-axis along the 2nd raw of the 1st slice (DESC_0 or NN=0), for each cube corresponding to a different subsample.
