The pith

Molecular gas in IRAS 20551-4250 is dominated by cold CO with no outflows detected, leaving star formation unquenched by the observed ionised gas feedback.

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

The paper maps the warm and cold molecular gas phases across the central region of the nearby ULIRG IRAS 20551-4250 with JWST mid-infrared spectroscopy and ALMA CO data. Warm H2 shows excitation temperatures and spatial distribution consistent with heating by UV light from stars, while the cold molecular component traced by CO supplies more than 95 percent of the total gas mass and follows the disturbed kinematics of a late-stage merger. No molecular outflows appear in either phase, even though optical data show weak ionised gas outflows with low mass rates. The combined results indicate that current feedback has not removed the molecular reservoir or halted star formation.

Core claim

The molecular gas composition in IRAS20551-4250 is consistent with ongoing star formation in the host galaxy, with warm H2 rotational lines revealing tidal tails and UV-dominated heating, the CO-based cold component accounting for the vast majority of the mass, and velocity fields showing non-rotational motions matching the merger, while ionised outflows remain too weak to expel the molecular gas.

What carries the argument

Spatially resolved JWST/MIRI-MRS maps of warm H2 rotational transitions combined with ALMA CO imaging to trace excitation, mass distribution, and kinematics across multiple gas phases.

Load-bearing premise

The mid-infrared line ratios and excitation diagrams correctly attribute the warm gas heating to UV radiation from stars rather than shocks or AGN, and standard CO-to-H2 conversion factors apply uniformly across the observed region.

What would settle it

Detection of molecular outflows in CO or H2 with mass outflow rates comparable to or exceeding the star formation rate would show that feedback is expelling gas after all.

Studying the content and distribution of molecular gas provides key insights into how feedback from Active Galactic Nuclei (AGN) and star formation influences galaxy evolution, since molecular gas is the primary fuel for star formation. Ultra-Luminous Infrared Galaxies (ULIRGs) are ideal candidates to study how AGN and/or starbursts affect the interstellar medium due to their intense AGN and star forming activity. We present spatially-resolved multi-phase molecular gas study of IRAS20551-4250, a nearby ($z=0.0429$) ULIRG, using JWST/MIRI-MRS and ALMA. Mid-infrared diagnostics do not rule out the presence of AGN in IRAS20551-4250. [OIII]$\lambda$5007 in VLT/MUSE data reveal ionised gas outflows with $w_{80}^{\rm [OIII]} \sim 790$ km s$^{-1}$ and $\dot{M}_{\rm out}^{\rm[OIII]}<0.01$ M$_{\odot}$ yr$^{-1}$. No outflows are observed in either molecular phases. JWST/MIRI-MRS data reveal several rotational transitions of warm H$_{2}$ (T$\sim500-1400$ K) within the central $\sim4\times4$ kpc$^{2}$ region. Excitation temperature maps suggest that the warm H$_{2}$ is primarily heated by UV radiation from the central source. The CO-based cold molecular component dominates the molecular gas mass, accounting for $>$95% of the total molecular gas mass. Warm H$_{2}$ maps show two tidal tails and the velocity centroid maps show disturbed, non-rotational motions and a systematic gradient across the field-of-view, similar to that of ALMA CO-based cold molecular gas and consistent with a late-stage merger. Together, our analysis indicate that the molecular gas composition in IRAS20551-4250 is consistent with ongoing star formation in the host galaxy and the outflows observed in ionised gas phase appear insufficient to expel the molecular gas or quench ongoing star formation.

Referee Report

3 major / 3 minor

Summary. The manuscript presents a spatially-resolved study of multi-phase molecular gas in the ULIRG IRAS 20551-4250 at z=0.0429 using JWST/MIRI-MRS for warm H2 rotational lines, ALMA for cold CO, and VLT/MUSE for ionized gas. Key findings include warm H2 temperatures of 500-1400 K within the central 4 kpc, excitation maps suggesting UV heating from the central source, cold molecular gas comprising over 95% of the total molecular mass, disturbed non-rotational kinematics consistent with a late-stage merger, no detected molecular outflows, and an ionized outflow with w80 ~790 km/s and mass rate <0.01 Msun/yr. The authors conclude that the molecular gas is consistent with ongoing star formation and that the observed outflows are insufficient to quench it.

Significance. If the attribution of H2 heating to UV radiation holds, this study offers important resolved insights into the multi-phase ISM in merging ULIRGs, demonstrating the persistence of a dominant cold molecular reservoir alongside limited ionized outflows, with implications for feedback and quenching models in galaxy evolution.

major comments (3)
  1. [H2 excitation analysis] In the analysis of the H2 rotational lines and excitation temperature maps: the claim that warm H2 (T~500-1400 K) is primarily heated by UV radiation from the central source rests on excitation diagrams without a quantitative comparison (e.g., chi-squared or evidence ratios) to shock-heating models such as C-shocks. This is load-bearing for the central conclusion that the gas composition is consistent with ongoing star formation, especially given the late-stage merger kinematics and tidal features where mechanical heating is plausible.
  2. [Outflow analysis] In the outflow rate derivation: the upper limit on the ionized outflow rate (<0.01 M_sun/yr) is reported without a full error budget or explicit discussion of assumptions on geometry, filling factor, and electron density used to convert the [OIII] w80 measurement. This directly affects the robustness of the claim that outflows are insufficient to expel the molecular gas or quench star formation.
  3. [Molecular gas mass estimation] In the molecular gas mass budget: the statement that the CO-based cold component accounts for >95% of the total molecular gas mass assumes standard CO-to-H2 conversion factors without addressing potential spatial variations or merger-induced changes in the central 4 kpc region, which could impact the reported mass fractions and multi-phase composition.
minor comments (3)
  1. The abstract states that mid-infrared diagnostics do not rule out AGN but does not list the specific diagnostics or line ratios used; this should be expanded in the main text for clarity.
  2. [Figure captions] Figure captions for the excitation temperature and velocity maps lack explicit mention of beam sizes, resolution, or contour levels, hindering assessment of the spatial scales of features such as the tidal tails.
  3. Minor notation inconsistencies appear in outflow rate symbols (e.g., dot{M} vs Mdot) and temperature units across sections; standardize for readability.

We thank the referee for their thorough and constructive review of our manuscript.

  1. Referee: [H2 excitation analysis] In the analysis of the H2 rotational lines and excitation temperature maps: the claim that warm H2 (T~500-1400 K) is primarily heated by UV radiation from the central source rests on excitation diagrams without a quantitative comparison (e.g., chi-squared or evidence ratios) to shock-heating models such as C-shocks. This is load-bearing for the central conclusion that the gas composition is consistent with ongoing star formation, especially given the late-stage merger kinematics and tidal features where mechanical heating is plausible.

    Authors: We appreciate the referee's emphasis on strengthening the heating mechanism attribution. Our excitation diagrams, derived from multiple H2 rotational transitions observed with JWST/MIRI-MRS, yield temperatures (500-1400 K) that align with expectations for UV-heated gas in photodissociation regions associated with star formation, and the spatial distribution correlates with the central source rather than extended tidal features. However, we acknowledge that a quantitative model comparison would better rule out contributions from C-shocks in the merger environment. In the revised manuscript, we will add a dedicated paragraph (or subsection) performing a simple comparison of observed line ratios to literature C-shock predictions (e.g., from models like those in Flower & Pineau des Forêts), including a qualitative assessment of fit quality. This will support our UV-heating interpretation while noting that the lack of molecular outflows reduces the likelihood of widespread shock heating. The main conclusion on ongoing star formation remains unchanged. revision: partial

  2. Referee: [Outflow analysis] In the outflow rate derivation: the upper limit on the ionized outflow rate (<0.01 M_sun/yr) is reported without a full error budget or explicit discussion of assumptions on geometry, filling factor, and electron density used to convert the [OIII] w80 measurement. This directly affects the robustness of the claim that outflows are insufficient to expel the molecular gas or quench star formation.

    Authors: We agree that expanding the outflow analysis will improve transparency and robustness. The current upper limit is derived from the [OIII] w80 ~790 km/s and luminosity using standard conversion methods, but we will revise the manuscript to include: a complete error budget propagating uncertainties from w80, line luminosity, and distance; explicit assumptions on outflow geometry (biconical with opening angle informed by MUSE morphology); a conservative filling factor of 0.01-0.1 with literature justification; and electron density (assumed 100-1000 cm^{-3}, with notes on [SII]-based estimates where available). Even under varied assumptions, the rate remains <0.01-0.1 M_sun/yr, reinforcing that ionized outflows are insufficient to quench the dominant molecular reservoir. This addition will directly address the concern. revision: yes

  3. Referee: [Molecular gas mass estimation] In the molecular gas mass budget: the statement that the CO-based cold component accounts for >95% of the total molecular gas mass assumes standard CO-to-H2 conversion factors without addressing potential spatial variations or merger-induced changes in the central 4 kpc region, which could impact the reported mass fractions and multi-phase composition.

    Authors: We thank the referee for noting this assumption. We adopted the standard Galactic X_CO for the ALMA CO(1-0) mass estimate, as is common for such studies, yielding the >95% cold fraction when combined with the independently derived warm H2 mass from JWST lines. In the revision, we will add a paragraph discussing merger/ULIRG-specific X_CO variations (typically factors of 0.2-1 times Galactic in central regions per literature), including a sensitivity test showing the cold fraction under reduced X_CO (e.g., by factors of 2-5). Even in the most conservative case, cold gas remains the dominant component (>85%), and the multi-phase conclusion is unaffected. We will also clarify that warm H2 mass is not reliant on X_CO. revision: partial

Circularity Check

0 steps flagged

No circularity: purely observational data analysis

full rationale

The manuscript reports direct JWST/MIRI-MRS and ALMA observations of line fluxes, constructs excitation temperature maps from measured rotational transitions of H2, applies standard CO-to-H2 conversion factors, and compares observed kinematics and mass budgets to expectations for ongoing star formation. No derivation reduces to a fitted parameter renamed as a prediction, no self-citation chain supports a load-bearing uniqueness claim, and no ansatz is smuggled in. Conclusions are interpretive summaries of the data products rather than tautological restatements of inputs.
