Pith's one-line read A search of 465,610 DESI galaxies finds three new tidal-disruption 'light echoes' — galaxies whose extreme coronal emission lines betray a past stellar shredding — and measures a per-galaxy rate consistent with earlier surveys.

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
SLEIPNIR, a custom Python pipeline that flags ECLE candidates by scoring detections of iron coronal lines ([FeVII], [FeX], [FeXI], [FeXIV]) against strict criteria, with detection efficiency measured by planting simulated coronal lines into 10,000 real DESI spectra. The rate calculation rests on a visibility-time method: TDE peak X-ray luminosities are sampled from a luminosity function, converted to coronal line strengths using a linear scaling anchored to the TDE AT 2017gge (S_max/S_gge = L_max/L_gge), and evolved as power-law declines over 10 years, with cosmological time dilation accounted for per galaxy redshift.
What would settle it
Measure peak X-ray luminosity and peak coronal line strength for a sample of a dozen coronal-line TDEs; if the ratio S_max/L_max scatters widely around AT 2017gge's value, the linear scaling used in Equation 4 is invalid and the reported rate would need revision. Alternatively, re-running the visibility-time calculation with a nonlinear scaling and comparing the resulting rate to the observed number of detections would settle whether the anchor assumption biases the result.
Extended reading notes
Core claim
The central discovery is that DESI's Early Data Release contains three new TDE-linked ECLEs — Pidgeot, Raticate, and Raichu — identified by the SLEIPNIR pipeline and confirmed through multi-wavelength follow-up, and that the resulting galaxy-normalized rate, R_G = 5 (+5/-3) × 10^-6 galaxy^-1 yr^-1 at z ≈ 0.2, is consistent with previous SDSS Legacy and BOSS LOWZ rates. The paper also strengthens the mid-infrared colour-luminosity relation for coronal-line TDEs: objects with brighter MIR flares show more significant reddening at outburst, now quantified with quadratic and linear fits to the ΔW2 versus ΔW1 and Δ(W1-W2) versus ΔW2 relations.
Load-bearing premise
The rate calculation assumes that a TDE's peak coronal line strength scales linearly with its peak X-ray luminosity, using the single object AT 2017gge to set the proportionality; if that scaling is not universal, the visibility times and hence the rate shift systematically.
Editorial extensions
If this is right
- The full DESI survey is expected to yield roughly 35–50 new TDE-linked ECLEs, enabling rate measurements with much smaller Poisson uncertainties.
- The new rate point extends the galaxy-normalized ECLE rate versus stellar mass relation and keeps it consistent with the theoretical minimum TDE rate, implying that only a subset (roughly 5–50%) of TDEs produce observable coronal lines.
- The 205-object CrL-AGN sample provides a reference catalogue of the primary astrophysical contaminants in optical searches for TDE-linked ECLEs.
- The strengthened Δ(W1-W2) versus ΔW2 relation for coronal-line TDEs offers a mid-infrared colour diagnostic that can help separate TDEs from AGN flares.
Reading between the lines
- Because the rate rests on a single anchor object, future samples of a dozen coronal-line TDEs with both X-ray and coronal-line measurements would either validate or break the linear scaling; if the scatter is large, the quoted rate uncertainties are underestimated and the rate itself would need recalibration.
- The paper notes galaxies with [NeV] but no [FeVII] emission despite nearly identical ionization energies; this suggests the [NeV]/[FeVII] ratio could serve as a sensitive probe of the softness of the X-ray ionizing continuum, a diagnostic worth testing on the full DESI sample.
- The hint that the volumetric ECLE rate is higher than the BOSS LOWZ rate, if confirmed with complete DESI data, would support the theoretical expectation that TDE rates decline with redshift, tying ECLE rates to the cosmic evolution of tidal disruptions.

Referee Report
Summary. This paper presents a systematic search of the DESI Early Data Release for extreme coronal line emitters (ECLEs) using the SLEIPNIR pipeline. After processing 465,610 galaxies, the authors identify 208 galaxies with Fe coronal lines and, through a multi-wavelength classification involving optical/NIR/MIR photometry, archival spectra, and new follow-up spectroscopy, classify three objects (Pidgeot, Raticate, Raichu) as TDE-linked and the remaining ~205 as AGN-related. Using the visibility-time formalism of Callow et al., calibrated with the Sazonov X-ray TDE luminosity function, the AT 2017gge coronal-line anchor, and a power-law decline over 10 years, they derive a galaxy-normalized TDE-ECLE rate R_G = 5(+5,-3) × 10^-6 galaxy^-1 yr^-1 at median z = 0.2, together with mass-normalized and volumetric rates, and compare these with previous SDSS, BOSS, and literature TDE rates. They also update the MIR colour-luminosity relation for coronal-line TDEs.
Significance. If the rate estimate holds, the paper roughly doubles the known sample of TDE-linked ECLEs and demonstrates that DESI EDR is an effective discovery engine for nuclear transients. The reported rate is broadly consistent with previous ECLE rates and strengthens the conclusion that only a fraction of TDEs produce strong coronal lines. The paper's strengths are its transparency and reproducibility: the search code is public, the detection efficiency is measured with simulated DESI spectra, the false-positive sources are discussed in detail, and the sample is cross-checked against an independent DESI EDR ECLE search. The multi-epoch spectroscopy and WISE/NEOWISE analysis for the three TDE candidates are careful. The main weakness is that the galaxy-normalized rate rests on a single-object, host-independent calibration between X-ray luminosity and coronal-line strength; this calibration is not included in the quoted uncertainty budget and could shift the rate outside the stated errors.
major comments (2)
- [§6.2.1, Eq. (4); Table 13] The rate denominator is controlled by Eq. (4), S_max/S_gge = L_max/L_gge, where S is a pseudoequivalent width (pEQW) as used in the detection-efficiency simulation of §3.3. For a fixed line luminosity, pEQW is inversely proportional to the host-galaxy continuum, so Eq. (4) predicts a pEQW from X-ray luminosity with no dependence on the host. The DESI EDR sample spans stellar masses down to ~10^7 M_sun (Fig. 5), and the same TDE would have substantially different visibility times in a faint versus luminous host. Table 13 includes uncertainties on S_gge and L_gge but not this host-continuum systematic. I recommend validating Eq. (4) with the other ~13 known CrL-TDEs, or converting S to line luminosity and applying per-galaxy continua from FastSpecFit, and adding the resulting systematic to the rate budget. A factor-of-two change in the summed visibility time shifts R_G outside the quoted P
- [§6.2.1, Eq. (5); Table 13] The visibility-time integral is truncated at 10 years. The power-law index is sampled down to -5/12, for which the decline over 10 years from the 218-day anchor is only a factor of roughly 0.3; a substantial fraction of the simulated population could remain above the ~1.3 Å detection threshold after the truncation. The uncertainty budget in Table 13 does not include the choice of the 10-year cutoff. Please report the sensitivity of R_G to t_max (e.g., 5, 10, and 20 years) and include the cutoff as a systematic uncertainty if it is non-negligible.
minor comments (3)
- [§5.1.1, §5.1.2, §5.2.2, §5.2.3; Table 11] Several DESI target IDs in the section headings do not match Table 11. For example, §5.1.1 and §5.1.2 both list DESI 39627794400938039, while Table 11 assigns Pidgeot = 39633332819985805 and Raticate = 39627794400938039. Similar conflicts occur for Charizard and Fearow. Please correct the headings so each object has a unique, consistent ID.
- [Section 1, Section 6] The Introduction refers to 'Appendix 5.2' for the CrL-AGN sample; this should likely be Appendix D or a proper section number. There is also a typo in Section 6 ('we disuses') and a repeated word in the caption of Fig. 28 ('x' after Ciii).
- [Table 13] The entries 'AT2017gge peak CrL strength' and 'AT2017gge peak luminosity' are propagated from a single object. Clarify in the table notes that these do not include any host-continuum or transferability systematic, and that such a systematic is not yet estimated.
Circularity Check
No significant circularity: the ECLE rate is derived from detections and externally anchored visibility-time inputs, not from a fit or self-citation chain.
full rationale
The central rate R_G = N_ECLE / sum t_v,i (Eq. 6) is not an output of any fit that uses the three detections as input parameters. N_ECLE = 3 is a measured count from the DESI EDR search. The visibility-time denominator is constructed independently of those detections: peak X-ray luminosities are sampled from the Sazonov et al. (2021) luminosity function, mapped to coronal-line strengths through the single-object anchor AT2017gge (Eq. 4), evolved with theoretical power-law indices, and convolved with the detection efficiency measured by planting known ECLE lines into 10,000 simulated DESI spectra (Section 3.3). None of these inputs is adjusted to make the resulting rate match previous values; the comparison to SDSS Legacy, BOSS LOWZ, and literature TDE rates is an external consistency check, not a fit. The self-citations to Callow et al. (2024, 2025) describe the SLEIPNIR code and the visibility-time method, but the present paper re-states and re-implements the method with independent anchors, and it does not invoke any self-cited uniqueness theorem or forbid alternatives by citation. The single-object calibration underlying Eq. 4 is a legitimate scientific concern about host-galaxy transferability and calibration uncertainty, but it is not circular: the scaling is not defined in terms of the rate it is used to compute. No load-bearing step reduces by construction to its own inputs.

abstract
Here we present the results of our search through the Early Data Release (EDR) of the Dark Energy Spectroscopic Instrument (DESI) for extreme coronal line emitters (ECLEs) - a rare classification of galaxies displaying strong, high-ionization iron coronal emission lines within their spectra. With the requirement of a strong X-ray continuum to generate the coronal emission, ECLEs have been linked to both active galactic nuclei (AGNs) and tidal disruption events (TDEs). We focus our search on identifying TDE-linked ECLEs. We identify three such objects within the EDR sample, highlighting DESI's effectiveness for discovering new nuclear transients, and determine a galaxy-normalized TDE-linked ECLE rate of $R_\mathrm{G}=5~^{+5}_{-3}\times10^{-6}~\mathrm{galaxy}^{-1}~\mathrm{yr}^{-1}$ at a median redshift of z = 0.2 - broadly consistent with previous works. Additionally, we also identify more than 200 AGNs displaying coronal emission lines, which serve as the primary astrophysical contaminants in searches for TDE-related events. We also include an outline of the custom python code developed for this search.
