XARTATOMS 研究 M104（草帽星系）的热气体晕：用 XMM-Newton 与 Chandra 的 X 射线光谱，测出晕内气体的温度、密度、熵随半径的分布，并检验“引力束缚的静力气体”与“反馈加热的风”两种图景。数据是 XMM 的三次观测（中心 0900170101 加两个偏置指向），拟合用 Sherpa 的 APEC 热等离子体模型加多种背景成分。当前科学基线是 v18 拟合管线。
XARTATOMS studies the hot-gas halo of M104 (the Sombrero Galaxy): using X-ray spectra from XMM-Newton and Chandra it measures how the temperature, density and entropy of the halo gas change with radius, and tests the two competing pictures — a gravitationally bound hydrostatic gas versus a feedback-heated wind. The data are three XMM observations (central 0900170101 plus two offset pointings); the fitting uses Sherpa with an APEC thermal-plasma model plus several background components. The current science baseline is the v18 fitting pipeline.

四问目标（2026-10-14 PI 新增）
The four-question objectives (added by the PI on 2026-10-14)

|---|---|---|---|---|---|---|
| Q-AQ-A | 哪种本地拟合策略给出的投影温度可靠？ | Which local fitting strategy gives a reliable projected temperature? | QuestionedQuestioned | 内区（2–4′）参考 = MOS2 单相机（S3）：四个背景错设臂全部通过（偏差 +0.008…+0.014 keV，覆盖率 0.71–0.77）；8–10′ 无策略合格（kT ≤ 1 keV 上界撞墙 4–11%，CXB×1.1 偏差 +0.035 keV）；视场边缘与 2D 图未合格；阶段 3（MOS2 + kT 0.2–3 + 多起点，2,400 次拟合）运行中；红队 RT-02 后 D48 收窄为 Questioned（MOS2 优于 MOS1 成立，但 MOS2 自身未被证明干净 — D50/T159）— cognition-os/insights/I067_*.md；cognition-os/04_DECISION_LOG.md D50 |
Inner (2–4′) reference = MOS2-only (S3): passes all four background-misspecification arms (bias +0.008…+0.014 keV, coverage 0.71–0.77); 8–10′ none qualified (kT ≤ 1 keV bound hits 4–11 %, CXB×1.1 bias +0.035 keV); edge and the 2D map unqualified; stage 3 (MOS2 + kT 0.2–3 + multi-start, 2,400 fits) running; after red team RT-02, D48 is narrowed to Questioned (MOS2 preferred over MOS1 stands, but MOS2 itself is not shown clean — D50/T159) — cognition-os/insights/I067_*.md; cognition-os/04_DECISION_LOG.md D50 |

| Q-BQ-B | Chandra+XMM 联合的 M104 温度 profile 是什么（10′ 内）？ | What is the Chandra+XMM kT profile of M104 (within 10′)? | First profileFirst profile | 径向 kT 问题（升 vs 平）仍开放：扇区谱外热（A2 +0.22 / A1 +0.37 keV 点对比，外区未合格）；单温 Fe-L 硬度平（0.77–0.79 keV，2–12′，I068/T160）；Chandra-only 弱升（+0.16）；张力曾归因测量合同不匹配（I070），红队 RT-08 复核后该表述撤回（→ Questioned）：GTI 差仅 +0.017 keV、背景需 ×2.2–2.4 才够、内/外差翻号（+0.10 / −0.14…−0.20 keV）→ 和解偏差必须是梯度形（D54）→ 决定性检验 = Virgo 阶段 1 匹配合同测试 + 组合压力臂 + 旧 vs v2 mask 硬度对比 — cognition-os/insights/I070_*.md；cognition-os/04_DECISION_LOG.md D54 |
The radial kT question (rise vs flat) stays open: sector spectra are hotter outside (A2 +0.22 / A1 +0.37 keV point contrasts, outer unqualified); the one-temperature Fe-L hardness is flat (0.77–0.79 keV over 2–12′, I068/T160); Chandra-only rises weakly (+0.16); the tension was assigned to a measurement-contract mismatch (I070), but after red team RT-08 that headline is withdrawn (→ Questioned): the GTI difference is only +0.017 keV, the background would need ×2.2–2.4, and the inner/outer gap flips sign (+0.10 / −0.14…−0.20 keV) → any reconciling bias would have to be gradient-shaped (D54) → the decisive test is the matched-contract test on the Virgo stage 1 products plus a combined-stress arm and a historical-vs-v2 mask hardness comparison — cognition-os/insights/I070_*.md; cognition-os/04_DECISION_LOG.md D54 |

| Q-CQ-C | 为何 ~13′ 亮度反而比内侧和 15–30′ 更亮？ | Why is the intensity brighter at ~13′ than inside and at 15–30′? | Resolved: artefactResolved: artefact | 假象（Provisional，I065）：flux 已是每 arcmin²（B020），旧 flux/area 双重归一；裸 SB 比 1.37，冻结 kT 后 1.07；图像 1.041±0.068 无超出；WARP 星系团拟合为 0 — cognition-os/insights/I065_*.md；经受住红队 RT-01（4 条次要、0 条实质；图像检验 −2.7σ 支持无超出，I065 修订）；开放：外环拟合方法；15–45′ profile 为 Questioned（E039：偏移拟合简并/不自洽，需 0501 ODF + Virgo 重处理） |
Artefact (Provisional, I065): the saved flux is already per arcmin² (B020), so the old flux/area double-normalised; bare-SB ratio 1.37, 1.07 with kT frozen; images 1.041±0.068 show no excess; the WARP cluster fits to 0 — cognition-os/insights/I065_*.md; it survived red team RT-01 (4 minor, 0 material objections; the image test at −2.7σ supports no excess, I065 amendment); open: the outer-ring fit method; the 15–45′ profile is Questioned (E039: offset fits degenerate/inconsistent; needs the 0501 ODF + Virgo re-reduction) |

Intensity map done; the 2D proxy map (stage 2, E038): Fe-L × quadrant anchors; the joint MOS2+pn0 minor-axis vs disk contrast lies within ≲ 0.08–0.11 keV (calibrated intervals, radius/geometry-dependent, asymmetric: ±45° 2–5′ [−0.056,+0.076] keV) — the contrast response R≈0.67–1.0 sets the sensitivity; N>S is only a hint (cross-arm familywise p≈1), not a detection (E038 + RT-07 amendment) — cognition-os/experiments/E038_*.md (D49) |

未来 1–4 周计划
Plan for the next 1–4 weeks
计划完全来自 cognition-os/02_CURRENT_QUESTION.md（2026-10-14/15 节）与各 job 的 BRIEF/REPORT，不是本手册的发明。2026-10-15 21:49Z 更新：Q-A 阶段 3/4 完成（外区探索性：±0.05 keV 只是逐臂中位偏差包络，逐拟合 68% ≈ ±0.15 keV，D51→D54；8–10′ 张力“主要是合同不匹配”的表述已被 RT-08 撤回（Questioned，D54），等阶段 5 匹配合同判定）；Q-B 出现两方法分歧（谱外热 vs Fe-L 硬度平，I068），决定性测试 D52 等 Virgo 阶段 1；Q-C 经受住 RT-01；Q-D 2D 代理阶段 2 完成（对比 ≲0.08–0.11 keV）；红队已分诊 8 支（RT-01…RT-09，见 D54），RT-04/RT-10 运行中（待定）。
The plan comes entirely from cognition-os/02_CURRENT_QUESTION.md (2026-10-14/15 sections) and the job briefs/reports; it is not invented by this handbook. Update 2026-10-15 21:49Z: Q-A stages 3–4 done (outer exploratory: ±0.05 keV is only the per-arm median-bias envelope, per-fit 68 % ≈ ±0.15 keV, D51→D54; the claim that the 8–10′ tension is "mainly a contract mismatch" was withdrawn after RT-08 (Questioned, D54), pending the stage-5 matched-contract test); Q-B now has a two-method disagreement (spectra hotter outside vs Fe-L hardness flat, I068), with the decisive D52 test waiting for Virgo stage 1; Q-C survived RT-01; Q-D 2D proxy stage 2 done (contrast ≲0.08–0.11 keV); 8 red teams triaged (RT-01…RT-09, see D54); RT-04/RT-10 running (Pending).

本次更新
What's new
- 2026-10-15 13:09Z（首次 8 小时刷新）：Q-A 阶段 2 裁定内区参考 = MOS2 单相机（D48/I067），外区/边缘/2D 未合格，阶段 3 运行中；Chandra-only profile（E037）与 J-linked profile（T155）每 ≤1σ 一致；亮度图完成；2D 温度图按 D49 转入代理探索；红队 RT-01/RT-02 启动。
- 2026-10-15 21:49Z（第二次刷新）：Q-A 阶段 3（S4 外区/边缘未合格，测试偏差 ≤ 0.05 keV → D51 探索性引用）；阶段 4（8–10′ 张力 = 合同不匹配，I070/D52）；Fe-L 硬度第二方法平温（I068，RT-06 修订：单温反演平，等温性未确立）；2D 代理阶段 2（E038 + RT-07：校准区间 ≲0.08–0.11 keV、N>S 仅提示）；红队 6 支已分诊（RT-01 存活、RT-03 J-linked 非独立、RT-05 mask 61% → D53）；外区 15–45′ profile Questioned（E039）；Virgo 阶段 1 运行中。刷新期间新增（D54，21:55Z）：RT-08 撤回 I070 主表述（→ Questioned）、RT-09 修订 ±0.05 keV 口径（逐拟合 68% ≈ ±0.15 keV、组合压力未测）；RT-04/RT-10 启动；0501/0601 ODF 已下载校验。
- 2026-10-15 13:09Z (first 8-hour refresh): Q-A stage 2 sets the inner reference to MOS2-only (D48/I067), outer/edge/2D unqualified, stage 3 running; the Chandra-only profile (E037) and the J-linked profile (T155) agree within 1σ per ring; the intensity map is done; the 2D kT map moves to proxy exploration per D49; red teams RT-01/RT-02 launched.
- 2026-10-15 21:49Z (second refresh): Q-A stage 3 (S4 outer/edge not qualified, tested biases ≤ 0.05 keV → D51 exploratory quoting); stage 4 (the 8–10′ tension = contract mismatch, I070/D52); the Fe-L hardness second method is flat (I068, RT-06 amendment: the one-T inversion is flat, isothermality not established); 2D proxy stage 2 (E038 + RT-07: calibrated bounds ≲0.08–0.11 keV, N>S a hint only); 6 red teams triaged (RT-01 survives, RT-03 J-linked not independent, RT-05 mask 61 % → D53); the outer 15–45′ profile Questioned (E039); Virgo stage 1 running. During the refresh (D54, 21:55Z): RT-08 withdrew I070's headline (→ Questioned), RT-09 amended the ±0.05 keV wording (per-fit 68 % ≈ ±0.15 keV, the combined stress untested); RT-04/RT-10 launched; the 0501/0601 ODFs downloaded and verified.
- 2026-10-15（阶段 2 修订）：Q-C 13′ 超出改判为假象（I065/B020）——v18 保存的 flux 本就是每 arcmin²，旧 flux/area 双重归一；图与文字全部更正。Q-A 试点结果（无策略认证，T153）、Q-B 搁置与逐仪器路线（D46）、GTI 保留 2.filter（I066）、mask 规则 v2 与"残余必须建模"（E035）、Virgo 再抽谱计划（D47）入表。新增开问题：MOS1 静态硬过剩。
- 2026-10-15 (stage-2 revision): the Q-C 13′ excess is reclassified as an artefact (I065/B020) — the v18 saved flux was already per arcmin², so the old flux/area double-normalised; figure and text corrected throughout. The Q-A pilot result (no strategy certified, T153), the Q-B parking and per-instrument route (D46), keeping GTI 2.filter (I066), mask rule v2 with "the residual must be modelled" (E035), and the Virgo re-reduction plan (D47) entered the tables. New open problem: the MOS1 quiescent hard excess.
