Looking for Signatures of AGN Feedback in Radio-Quiet AGN
Round 1
Reviewer 1 Report
This review paper presents the results taken from the GMRT, VLA and VLBI multi-frequency observations probing different scales, from arcseconds to milliarcseconds, of nearby low-luminosity active galactic nuclei and also discusses observational and energetic signatures of the process of 'AGN feedback'. The paper is well-organized and clearly written. It can be published in the journal after a minor revision taking into account the comments listed below.
Abstract
The range ... suggest ==> The range ... suggests
'not one but multiple sets of jets' sounds a bit cumbersome and might be misleading. I guess the authors mean a number of periods of restarted / episodic jet activity, as it is mentioned below.
Introduction
Figure 1 caption:
- where is the 'relic' lobe in addition to two lobes seen on the map?
It would help either to mark it or describe its location.
- clarify that the lowest contour is at the level 0.3% of the map peak.
100s ==> hundreds

line 66: be consistent with the quote style, using either '' as above or "" as here.
Section 2
Spectral index in the relic lobe might be biased towards lower values due to features of the CLEAN algorithm used. Moreover, its uncertainty should be quite high being dominated by random errors in the low brightness regions. Not necessarily for this particular review paper, but it would be useful to construct the spectral index error map taking into account two sources contributing to the error budget: random error from the noise of the maps and systematic error from their alignment.
Figure 3 caption, last sentence: the bottom contour extent cannot define the inner jet PA, especially when mini-lobes/components are detected in quite different PA. It is better to omit this details re. PA and jet extent here and in the last para of Sec. 3.
Section 4
line 178: ranges from ==> is / is within a range
Section 5
para 1: The authors might want to add that a few NLSY1 galaxies observed with the VLBA within the MOJAVE program also showed one-sided source morphology.

line 334: DPAGN has not been introduced

Reviewer 2 Report
The authors present an extended collection of observational evidence for the manifestation of AGN feedback in Radio-quiet AGN. Given the scarcity of such evidence, these information are very interesting and provide a deeper look to the AGN feedback phenomenon that has been discussed in a range of contexts. The manuscript reads well but can be improved in coherency and also some parts need better elaboration and/or clarification. In the attached pdf file, I list my comments and suggestions, more or less in order of appearance. Since most comments can be easily implemented, I recommend publication after minor revision.

Reviewer 4 Report
The paper reviews the AGN feedback from pc to kpc scales, especially in radio aspect which could be complicated by star-formation activities and AGN jet/winds, etc. Although the AGN feedback is not well resolved and understood yet, this review has summarized recent results in detail, which will be useful for researchers in this field. The paper has been well written, I'd like to recommand to accept it for publication in Galaxies. Some minor comments are as follows.
Page 9, lines 306, 334, to give full words of KISSR and DPAGN if it appears at first time. Page 10, line 370, the RG AGN could be RQ AGN.
