“…Lenticular galaxies are excluded from the plot, as they are uniformly scattered. The distribution of galaxies in the figure is such that there is a separation between the elliptical galaxies placed in the upper right part of the plot and the barred lenticulars, spirals and barred spirals placed in the lower left part, as already shown in previous papers on this subject (Benedetto et al 2013;Feoli and Mancini 2009).…”

“…The main results of this line of research that have been found during this period of time are summarizable in this way: 1) there is no doubt that the correlation exists. It has been tested with a lot of different samples and fitting methods (Benedetto et al 2013;Feoli and Mele 2007;Feoli and Mancini 2009;Mancini and Feoli 2012); 2) there is no doubt that the relation is very competitive with all the others to fit the experimental data, in particular its intrinsic scatter is very low (Saglia et al 2016) just like the more popular M • − σ relation and the Hopkins (2007a); 3) the relation can be very useful to understand the evolution of galaxies, just like the HR diagram is for the evolution of stars (Feoli and Mancini 2009) and allows good predictions of the masses of some black holes that do not follow the M • − σ (Benedetto et al 2013) as well as of the behavior of AGN (Mancini and Feoli 2012).…”

We have studied, in a series of papers, the properties of the M • versus M G σ 2 relation and we have found that it is useful to describe the evolution of galaxies in the same way as the HR diagram does for stars and to predict the masses of Supermassive Black Holes that are difficult to be guessed using other scaling relations. In this paper, analyzing five samples of galaxies, we find that this relation has intrinsic scatter similar to the M • − σ, but follows the theoretical models much better than the M • − σ. Furthermore, we analyze the role of the bulge mass in the behavior of M • versus M G σ 2 relation because the difference with the M • − σ is often determined by the choice of the right sample of galactic masses.Keywords host galaxies; SMBHs; masses of galaxies 1 Introduction An evidence of the last three decades of astrophysical observations is that almost each galaxy hosts a Supermassive Black Hole (SMBH). Another important discovery in this field of research is the existence of a correlation between the mass of SMBHs and the properties of the host galaxies, such as the velocity dis-

“…The goal of the present study is to strengthen the case for a very early feedback process between the growth of the total stellar population mass of a bulge (or a galaxy) and the growth of its central massive body. The mo-tivation to consider a very early feedback comes from the correlation between the mass of the SMBH and the properties of its host galaxy (bulge; e.g., Benedetto et al 2013;Graham, & Scott 2013;Saxton et al 2014), in particular the total stellar mass. The properties of the bulge-SMBH masses correlation itself shows that this correlation cannot be driven by many mergers of low mass galaxies (Ginat et al 2016).…”

Jet-driven active galactic nucleus feedback in galaxy formation before black hole formation

We propose a scenario where during galaxy formation an active galactic nucleus (AGN) feedback mechanism starts before the formation of a supermassive black hole (SMBH). The supermassive star (SMS) progenitor of the SMBH accretes mass as it grows and launches jets. We simulate the evolution of SMSs and show that the escape velocity from their surface is ≈ several × 10 3 km s −1 , with large uncertainties. We could not converge with the parameters of the evolutionary numerical code mesa to resolve the uncertainties for SMS evolution. Under the assumption that the jets carry about ten percent of the mass of the SMS, we show that the energy in the jets is a substantial fraction of the binding energy of the gas in the galaxy/bulge. Therefore, the jets that the SMS progenitor of the SMBH launches carry sufficient energy to establish a feedback cycle with the gas in the inner zone of the galaxy/bulge, and hence, set a relation between the total stellar mass and the mass of the SMS. As the SMS collapses to form the SMBH at the center, there is already a relation (correlation) between the newly born SMBH mass and the stellar mass of the galaxy/bulge. During the formation of the SMBH it rapidly accretes mass from the collapsing SMS and launches very energetic jets that might unbind most of the gas in the galaxy/bulge.

“…The reason is that this relation exhibits solid theoretical foundations and can play the role of an HR diagram for galaxies (Feoli and Mancini 2009;Mancini and Feoli 2012). Furthermore, it has already shown to predict the masses of SMBH better than other relations in some particular cases (Benedetto et al 2013). In this paper, the objective is to analyze the predictive power of the scaling relation between the mass of a SMBH and kinetic energy and to enhance the statistical analyses in Iannella and Feoli (2020).…”

In the context of scaling relations between Supermassive Black Holes and host-galaxy properties, we aim to enhance the comparison between M • −M G σ 2 and M • − σ relations from a statistical point of view. First, it is suggested to take into account the predictive accuracy of the scaling relation, in addition to the classical measures of goodness of fit. Here, prediction accuracy is fairly evaluated according to a leave-one-out cross-validation strategy. Then, we spread more light on the analysis of residuals from the fitted scaling relation, in order to provide more useful information on the role played by the different variables in their correlation with the black hole mass. The findings from six samples are discussed.
