A Global Inventory of Feedback

Round 1

Reviewer 1 Report

This paper presents a very interesting and informative study of the relative contributions to the large scale feedback in galaxies and clusters.  The authors are careful to point out sources of uncertainties and basic assumptions, which makes for a valuable contribution.  

I have only a couple of minor comments:

1)  lines 221-225: The notes to Table 1 refer to energy and momentum that are "created".  It woud be more appropriate to use the word "contributed".

2) lines 246-247 and line 263 state that the color coding is such as to describe the fraction of galaxies in which star formation has been quenched.  However, the color bar on the right of the figure describes the color coding in terms of a Quiescent fraction.  For the non-specialist, it may not be clear whether "quenching of star formation" and "quiescent fraction" represent the same concept.

3) line 305:  the notation M* introduced earlier in the text becomes somewhat awkward here when  a superindex is added. I suggest moving the asterisc to a subindex.

4) line 313: are not consistent with simple model of ---> are not consistent with simple models of

5) line 323: "ratio jets" .... ?

6) lines 341-343 leave the reader wondering:  Is the expectation of a mass dependence in the relative importance of feedback from the two sources met?     

Author Response

Reply to comments of referee:

1) We have changed "created" to "contributed"

2) We have changed "quiescent" in the figure to "quenched"

3) We have replaced "*" with "star" throughout the text and figures

4) Fixed

5) Fixed

6) Reworded to say "Since the ratio of the mass of the supermassive black hole to the galaxy stellar mass increases steeply with mass, there will be a mass-dependence in the relative importance of feedback from the two sources."

Reviewer 2 Report

The paper presents the overall contribution of stars, winds, and jets to feedback in galaxies, groups, and clusters of galaxies. The results are interesting and can serve as a general guide to the most important feedback processes at each type of object. 

As such I recommend publication.

My only comment is to give numbers to the two equations in lines 175 and 178. Indeed in line 183: "We adopt the theoretical relation (equation 2), but . . ", it seems that the authors gave numbers, but I cannot see them in the text.

Author Response

We see the equation 1 and 2 labels in both our Word and pdf files. Not sure why they were lost in the version reviewed by the referee.
