Lauer T. R. Fig. For further information on the SFR estimate in models we refer to Section 3 in G11. To measure the error in stellar mass induced by redshift uncertainty, we compare the stellar mass estimated using spectroscopic versus photometric redshifts. We find that the observed best-fitting relations for high-z subsamples (S-II to S-V) are almost similar and consistent with model predictions within uncertainties. Babul A. (IV) With a given similar stellar mass binsize, the peak value of stellar mass distribution is overpredicted by G11 and DLB07 in all subsamples. (2011) SAM agrees well with these observations, below z < 0.5 the model fails to reproduce the observed growth. The SED templates are generated assuming 0.02 and 0.008 metallicities, corresponding to 1 Z⊙ and 0.4 Z⊙, respectively, and exponentially declining SFR ∼ ∝e−t/τ where t is the age of a galaxy and τ have nine values between 0.1 and 30 Gyr. Furthermore, we apply a robust linear regression and estimate the best-fitting relation (log(MS) = β × log(M200) + α) over the whole data in both observations and SAMs, presented in Table 4. The halo mass distribution for the total number of the galaxy groups within S-II to S-V peaks around log(M200/M⊙) ∼ 13.7 ± 0.2. Unless stated otherwise, we adopt a cosmological model, with (ΩΛ, ΩM, h) = (0.75, 0.25, 0.71), where the Hubble constant is characterized as 100 h km s−1 Mpc−1 and quote uncertainties on 68 per cent confidence level.

In Stellar, you are stargazers, calibrating your telescopes to bring into view celestial objects of various types — planets, moons, asteroids, interstellar clouds, black holes, even satellites — as you create a beautiful display of the night sky! We present multi-wavelength observations of the brightest galaxies in four X-ray luminous groups at z ∼ 0.37 that will merge to form a cluster comparable in mass to Coma. Bernyk M. We present the distribution of the specific star formation rate (sSFR) of the BGGs in Fig. 4 shows the evolution of the mean stellar mass of the BGGs in observations (filled dimonds) over the redshift range of 0.1 < z < 1.3. The main advantage of our study is in the direct detection of galaxy groups which provides a unique opportunity to study the diversity of the BGG properties for a well-defined sample in terms of the mass and the redshift of objects. Board Game Atlas Forum.

Ordered by increasing stellar mass, the four brightest group galaxies (BGGs) present a time sequence where BGG-1, 2, & 3 are in merging systems and BGG-4 is a massive remnant (M ∗ = 6.7 × 10 11 M⊙). This paper is structured as follows.

The grey highlighted area represents the 68 per cent confidence interval of the best fit to the data. However, the G11 prediction is closer to observations than the DLB07 model. We added the most popular Currencies and The B06 model has a best consistency with the data below z ∼ 0.5, but above this redshift all models fail to predict the observed stellar mass distribution of the BGGs. You can convert At least ∼13 ± 3 to 60 ± 5 per cent of BGGs in our low-z (S-II) and high-z (S-V) subsamples are galaxies with SF rate above ∼1 M⊙yr−1. We compare our results with sample drawn from the Millennium simulations with three SAMs (G11, DLB07, and B06). We compare the evolution of the average SFR of BGGs with the evolution in the SFR of the SF galaxies (MS) using the SFR-mass sequence presented in Whitaker et al. Brodwin M.

The M200–z plane enables us to adopt a similar halo mass range for the last four subsamples (S-II to S-V).

The Kurtosis of the stellar mass distribution of the BGGs versus redshift (upper panel). (I) The subsample S-V shows a secondary peak at log(MGd/M⊙) ≈ 10.2. We find that both G11 and DLB07 models perform similarly in predicting the stellar mass distribution of the BGGs at all redshift and halo masses considered. The predicted Kurtosis and skewness values by SAMs shows no or a little evolution. 2009, which has been taken from Wuyts et al.
