The pith

ELT 3D spectroscopy produces spatially resolved AGN outflow maps that can be compared directly to star-formation rate maps at sub-kpc scales without assuming outflow geometry.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper argues that adaptive-optics-assisted 3D spectroscopy using the ELT multi-IFU instrument SHARP/VESPER will generate maps of outflow properties that deliver instantaneous outflow rates over the full field of view. These maps can then be paired with resolved star-formation rate maps to examine how outflows and star formation interact across individual galaxies. The approach targets a representative sample of galaxies at 1.5 < z < 2.5 that covers stellar masses from 10^8 to above 10^10 solar masses. A reader would care because the method reduces uncertainties that have limited earlier long-slit studies and could clarify the role of AGN feedback in regulating star formation during cosmic noon.

Core claim

The central claim is that the availability of adaptive-optics-assisted 3D spectroscopy with the ELT multi-IFU instrument SHARP/VESPER enables the construction of spatially resolved outflow property maps, providing instantaneous outflow rates across the entire field of view without assuming outflow geometry, and thus significantly reducing the uncertainties compared to methods based on longslit spectroscopy; furthermore, combining these maps with resolved star formation rate maps allows a direct comparison between outflow properties and star-formation activity across the galaxy, providing key insights into how AGN feedback regulates star formation down to sub-kpc scales when applied to a repr

What carries the argument

Spatially resolved outflow property maps from adaptive-optics-assisted multi-IFU spectroscopy that supply instantaneous outflow rates without assuming outflow geometry.

If this is right

  • Derivation of mass and energy carried by outflows across entire galaxies becomes possible without geometry assumptions.
  • Correlations between outflow quantities and both AGN and host-galaxy properties can be measured on a statistical sample.
  • Effects of AGN feedback on the overall galaxy population at cosmic noon can be revealed.
  • Physical mechanisms driving the outflows can be constrained by the sub-kpc comparisons.
  • The interplay between AGN activity, outflows, and star formation can be investigated systematically across low- to high-mass systems.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • The same mapping technique could be extended to other redshift ranges once similar IFU capabilities exist at different facilities.
  • Local suppression or enhancement of star formation by outflows might be detectable as spatial anti-correlations in the maps.
  • If the method works, existing long-slit studies could be re-interpreted with quantified geometry uncertainties.
  • Galaxy evolution simulations could be tested against the observed distribution of outflow rates versus local SFR.

Load-bearing premise

The assumption that adaptive-optics-assisted 3D spectroscopy with the ELT multi-IFU instrument SHARP/VESPER will enable construction of spatially resolved outflow property maps providing instantaneous outflow rates across the entire field of view without assuming outflow geometry.

What would settle it

If the first SHARP/VESPER observations still require an assumed outflow geometry to derive mass and energy rates, or if the resulting maps show no spatial correlation with resolved SFR maps at sub-kpc scales.

To better understand the role of AGN-driven outflows as a mechanism for heating or sweeping up gas over distances comparable to the size of the galaxy in its evolution, and to explore their physical characteristics as a function of AGN and host galaxy properties, it is necessary to have a statistical sample of AGNs selected from a uniform sample of galaxies with spectroscopic coverage of key restframe optical emission lines. To assess the impact of AGN-driven outflows on their host galaxies, we need to derive the mass and energy carried by the outflows, as well as correlations of these quantities with both AGN and host galaxy properties, in order to reveal their effects on the galaxy population and constrain the physical mechanisms driving the outflows. The availability of adaptive-optics-assisted 3D spectroscopy with the ELT multi-IFU instrument SHARP/VESPER enables the construction of spatially resolved outflow property maps, providing instantaneous outflow rates across the entire field of view without assuming outflow geometry, and thus significantly reducing the uncertainties compared to methods based on longslit spectroscopy. Furthermore, combining these maps with resolved star formation rate (SFR) maps allows a direct comparison between outflow properties and star-formation activity across the galaxy, providing key insights into how AGN feedback regulates star formation down to sub-kpc scales. By applying this approach to a representative sample of galaxies at cosmic noon ($1.5 < z < 2.5$), spanning a wide range of stellar masses from low-mass systems ($M_\star = 10^{8-10}\,M_\odot$) to the massive end ($M_\star > 10^{10}\,M_\odot$), we aim to systematically investigate the interplay between AGN activity, outflows, and star formation in the galaxy population as a whole.

Referee Report

2 major / 1 minor

Summary. The manuscript outlines a proposed observing program using adaptive-optics-assisted 3D spectroscopy with the ELT multi-IFU instrument SHARP/VESPER to map AGN-driven outflows and resolved star-formation rates in galaxies at 1.5 < z < 2.5 across a stellar-mass range from 10^8 to >10^10 M_⊙, with the goal of studying AGN feedback regulation of star formation at sub-kpc scales without assuming outflow geometry.

Significance. If executed, the proposed observations could in principle yield spatially resolved outflow-rate maps that enable direct comparison with SFR maps and reduce geometric uncertainties relative to long-slit methods. However, the manuscript contains no data, derivations, sample selection criteria, observing strategy, or analysis, so its contribution is limited to a high-level science case rather than a completed scientific result.

major comments (2)
  1. [Abstract] Abstract: the central claim that SHARP/VESPER will deliver instantaneous outflow rates across the entire field of view without assuming outflow geometry is presented as an established capability, yet no instrument performance metrics, data-reduction approach, or validation against existing IFU data or simulations are supplied to support this assertion.
  2. [Abstract] Abstract: the stated requirement for a 'statistical sample of AGNs selected from a uniform sample of galaxies with spectroscopic coverage of key restframe optical emission lines' is not accompanied by any concrete selection criteria, parent catalog, or redshift-dependent completeness estimates, leaving the feasibility of the claimed population-level conclusions unassessable.
minor comments (1)
  1. The abstract is written as a single extended paragraph containing multiple compound claims; breaking it into shorter paragraphs would improve readability.

Simulated Author's Rebuttal

We thank the referee for their review. Our manuscript presents a science case for the proposed SUNRISE-3D program rather than an analysis of existing observations. We address the two major comments below and indicate where revisions will be made to improve clarity and support for the claims.

  1. Referee: [Abstract] Abstract: the central claim that SHARP/VESPER will deliver instantaneous outflow rates across the entire field of view without assuming outflow geometry is presented as an established capability, yet no instrument performance metrics, data-reduction approach, or validation against existing IFU data or simulations are supplied to support this assertion.

    Authors: The referee correctly notes that the manuscript does not supply instrument performance metrics, data-reduction details, or validation studies. These claims derive from the published design specifications and performance expectations for the SHARP/VESPER multi-IFU instrument on the ELT. In revision we will add citations to the relevant instrument papers and include a short paragraph summarizing how the simultaneous multi-IFU coverage enables geometry-independent outflow mapping. We will also moderate the abstract wording to reflect that this is an expected capability based on instrument design rather than a demonstrated result. revision: yes

  2. Referee: [Abstract] Abstract: the stated requirement for a 'statistical sample of AGNs selected from a uniform sample of galaxies with spectroscopic coverage of key restframe optical emission lines' is not accompanied by any concrete selection criteria, parent catalog, or redshift-dependent completeness estimates, leaving the feasibility of the claimed population-level conclusions unassessable.

    Authors: We agree that the absence of explicit selection criteria and completeness estimates makes the statistical feasibility difficult to evaluate from the current text. The manuscript intentionally keeps the description at a high level to emphasize the scientific motivation. In the revised version we will add a dedicated subsection outlining example selection criteria drawn from existing parent catalogs (e.g., CANDELS, 3D-HST), approximate number densities at 1.5 < z < 2.5, and a brief discussion of redshift-dependent completeness for the key emission lines. This will allow readers to assess the practicality of assembling the sample. revision: yes

Circularity Check

0 steps flagged

Proposal abstract contains no derivations or self-referential claims

full rationale

This manuscript is a forward-looking proposal for an ELT/SHARP-VESPER observing program at 1.5<z<2.5. It contains no data, no equations, no fitted parameters, no modeling, and no completed analysis. The text describes instrument capabilities and survey goals without any derivation chain, self-citation load-bearing steps, or quantities that reduce to inputs by construction. The central claims about outflow maps and SFR comparisons are statements of intended future work, not derived results.
