The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
Equipartition analysis of synchrotron self-absorption spectra (peak flux, break frequency, and electron power-law index) that yields the average density of the radio-emitting volume; comparison of that density to the much higher line-ratio density then gives the volume filling factor of the dense ECL gas.
What would settle it
Deeper multi-frequency radio monitoring of a larger ECLE sample that either (a) yields filling factors outside 10^{-5}–10^{-2} under the same equipartition assumptions or (b) shows the radio and coronal-line regions to be co-spatial at the same density would falsify the claimed clumpy geometry.
Extended reading notes
Core claim
Radio spectral modeling of four ECLEs shows that the gas producing extreme coronal lines is clumpy, with volume filling factor 10^{-5} ≲ f_V ≲ 10^{-2}, and is likely distinct from the radio-emitting region (for example a clumpy toroidal geometry). About half of the 27-object sample is radio-detected at luminosities consistent with TDE or AGN outflows.
Load-bearing premise
Converting the radio-derived density of relativistic electrons into a total gas density (and therefore into a filling factor) rests on assumed values for the relativistic-electron fraction and on a spherical thin-shell geometry; large changes in either assumption move the filling-factor range by orders of magnitude.
Editorial extensions
If this is right
- The dense gas that produces extreme coronal lines cannot be a smooth spherical shield; it must be concentrated in discrete clouds or a clumpy torus.
- Time-variable ECLEs become direct laboratories for the sub-parsec gas geometry around previously quiescent supermassive black holes.
- Roughly half of ECLEs launch radio outflows whose energies and densities sit in the same range as ordinary TDEs and radio-quiet AGN.
- Future multi-wavelength campaigns can jointly constrain accretion luminosity, photoionization, and mechanical feedback with a single class of objects.
Reading between the lines
- If the low filling factor is generic, models that treat the circumnuclear medium as a uniform density sphere will systematically overestimate the mass of gas available for coronal-line emission.
- The same radio-plus-line method could be applied to ordinary AGN and late-time TDEs that lack extreme coronal lines to test whether the clumpy geometry is what makes ECLEs special.
- Late-time radio monitoring of a larger TDE sample may reveal a higher incidence of decelerated off-axis jets than previously reported, aligning the ECLE jet fraction with that of radio-loud AGN.

Referee Report
Summary. The paper presents the first systematic radio study of 27 low-redshift (z<0.3) extreme coronal line emitters (ECLEs). Combining archival VLA surveys (VLASS, FIRST, NVSS) with new targeted VLA and GMRT observations of a subset, the authors find that roughly half the sample produces radio synchrotron emission whose luminosity and evolution are consistent with non-relativistic TDE outflows or radio-quiet AGN. For four events with multi-band SEDs (SDSS J0748, SDSS J0938, SDSS J1241, AT 2020vdq) they fit synchrotron self-absorption spectra, apply equipartition (BD13 with Newtonian corrections) under a spherical thin-shell geometry, and derive outflow energies and circumnuclear densities. Comparing the radio-derived density (n_e ~ 100 cm^{-3}) with the much higher densities required by the optical coronal lines (n_l ~ 10^{6-9} cm^{-3}) they conclude that the ECL-producing gas is clumpy, with a volume filling factor 10^{-5} ≲ f_V ≲ 10^{-2}, and is likely spatially distinct from the radio-emitting region (e.g., a clumpy torus).
Significance. If the qualitative geometric conclusion holds, the work supplies one of the first direct observational constraints on the sub-parsec CNM geometry in formerly quiescent nuclei that host TDEs, and it links photoionization diagnostics to dynamical outflow probes in a single class of objects. The multi-wavelength compilation, public data release via OTTER, and open analysis code are genuine strengths that will enable follow-up. The numerical f_V window is secondary; the demonstration that radio and optical densities cannot be reconciled under spherical symmetry is the load-bearing result and is of clear interest to the TDE/AGN community.
major comments (3)
- Section 4.4 and Eq. (6): the quoted numerical range 10^{-5} ≲ f_V ≲ 10^{-2} is obtained by converting n_e to a total gas density via the ad-hoc choice f_rel ≈ 0.01 and then dividing by n_l ~ 10^{6-9} cm^{-3}. The manuscript itself notes that f_rel is poorly constrained (literature allows ~10^{-3}-0.1). Because f_V scales linearly with 1/f_rel, the numerical bounds move by 1-2 dex under plausible variations. The abstract and conclusion present the range as a firm result of the radio modeling; it should be re-framed as an order-of-magnitude estimate whose dominant systematic is f_rel, or the range should be shown explicitly as a function of f_rel.
- Section 3.3 and the discussion of SDSS J1241: the equipartition formulae assume spherical symmetry (f_A = 1, f_emit = 0.1). For SDSS J1241 the same analysis yields β ≈ 0.006, which the authors themselves interpret as evidence that spherical geometry is an oversimplification (or that the radio-emitting region lags the leading edge). Because the density contrast that drives the f_V argument is obtained under that spherical average, the claim that the ECL and radio regions are 'likely distinct' needs either (i) an explicit collimated-outflow re-calculation (f_A ≪ 1) showing that the density discrepancy survives, or (ii) a clear statement that the geometric conclusion is qualitative only and does not rest on the precise numerical value of n_e.
- Section 4.3: the ~50 % radio-bright fraction is repeatedly cited as a population result, yet the text correctly notes that most VLASS/FIRST limits are non-constraining for typical non-relativistic luminosities at z ≳ 0.04 and that only four events lie inside the volume where VLASS can detect ν L_ u ~ 10^{38} erg s^{-1}. The deeper targeted sample is small (10 events) and biased toward previously interesting targets. The abstract and conclusion should state the fraction as a lower limit (or as a detection rate within the sensitivity-limited subsample) rather than as a robust population statistic.
minor comments (5)
- Table 3 / Figure 3: for SDSS J0938 and the second epoch of AT 2020vdq the peak flux and break frequency are reported only as limits; the corresponding equipartition quantities are therefore also limits. The text sometimes treats them on equal footing with the well-constrained epochs; a short clarifying sentence would help.
- Figure 1 caption: several optical light curves are noted as not host-subtracted; it would be useful to mark those panels explicitly (e.g., with an asterisk) so the reader does not misinterpret continuum levels.
- Section 3.2: the choice s = 1 (instead of the Granot & Sari 2002 prescription) is justified by an unphysical p ≈ 4 for SDSS J1241, but the effect of s on the derived p, u_a and F_ u,p is not quantified. A one-sentence sensitivity check would strengthen the modeling section.
- Throughout: a few typographical inconsistencies remain (e.g., 'Newtownian', 'guassian', 'V ariable', missing spaces after periods in Table 1 footnotes). A careful proof-read is warranted.
- Section 2.6 / Table 4: the eROSITA association with AT 2021acak is interesting but rests on a 2.9 arcsec offset; a brief note on the chance-coincidence probability would be helpful.
Circularity Check
No significant circularity: f_V is an independent density-ratio comparison, not forced by construction or self-citation.
full rationale
The paper is a multi-wavelength observational study. Radio SEDs of four ECLEs are fit with a standard synchrotron self-absorption model (Eq. 1) whose free parameters (p, F u,p, u a) are constrained by the data via MCMC; equipartition formulae (BD13, with Newtonian corrections) then yield ne, Req and Eeq under explicit geometric assumptions (spherical thin shell, femit=0.1). These radio-derived densities are compared to independent optical-line densities nℓ∼10^6–9 cm-3 taken from the literature. The numerical mismatch is converted to a volume-filling factor via the order-of-magnitude estimate fV∼ne/(frel nℓ) with a conservatively chosen frel≈0.01 (Eq. 6). Nothing in this chain is defined in terms of the final claim, fitted to the target quantity, or justified solely by an unverified self-citation. Self-citations (OTTER database, prior TDE radio papers by overlapping authors) supply comparison samples and standard analysis choices; they do not close a logical loop that forces the quoted fV range or the clumpy-geometry conclusion. The result is therefore an ordinary (if assumption-dependent) observational inference, not a circular derivation. Score 1 only for the minor presence of self-citations that are not load-bearing.

abstract
A tiny fraction ($\ll1\%$) of galaxies display luminous, high-ionization metal emission lines, which may be persistent or variable. These extreme coronal lines (ECLs) are produced when soft X-ray photons intercept dense gas ($n\gtrsim10^{6-7}~{\rm cm^{-3}}$). The high X-ray flux required implicates intense nuclear activity, likely originating from tidal disruption events (TDEs) and active galactic nuclei (AGN). As ECLs are rarely seen even within these classes, their production may also require specific environmental conditions, but the details remain unclear (e.g., the geometry and volume filling factor of the ECL-producing gas). Here, we present the radio properties of a population of $27$ low-redshift ($z<0.3$) ECL emitting galaxies (ECLEs), providing a unique and previously unexplored probe of the properties of the circumnuclear medium (CNM; $\lesssim1$ pc from the black hole) in these systems. We find that $\sim 50\%$ of ECLEs produce radio synchrotron emission with luminosity and evolution consistent with TDEs and/or AGN. Radio spectral modeling of four ECLEs reveals that the ECL-producing region is (1) clumpy with a low volume filling factor ($10^{-5}\lesssim f_{V}\lesssim10^{-2}$) and (2) likely distinct from the radio emitting region (implying, e.g., a clumpy toroidal geometry). For time-variable ECLEs, these are some of the first observational constraints on the CNM geometry in formerly quiescent galactic nuclei. The unique nature of ECLEs makes them an excellent high-energy laboratory to connect the physics of accretion, photoionization, and feedback in galactic nuclei, thus motivating continued multi-wavelength monitoring.
