See Dimopoulos, Ricci, Paltani, ApJ 992, 64 (2025), Paltani & Ricci, A&A 607, A31 (2017), and Ricci & Paltani, ApJ 945, 55 (2023)
Full circumnuclear AGN model including a dusty torus, polar hollow cone, accretion disk, and broad line region.
The RXagn1 models differs only in terms of geometry. As a result all the technical details applicable to RXToPo remain the same.
| Property | Value |
|---|---|
| Input continuum | Cutoff power-law; cutoff energy fixed at 200 keV |
| Energy range | 0.3 – 300 keV |
| Spectral resolution | ΔE = 20 eV (4 eV retained in Fe Kα, Fe Kβ, Fe edge, and Ni Kα regions |
| Composition | Lodders et al. (2009) |
| Physical processes | Rayleigh scattering, Compton scattering on bound electrons, dust grain interactions |
RXTagn consists of five spectral components are provided based on the photon interaction history.
The relations ALL = CNT + RPRC and RPRC = SCAT + FLUO hold.
Parameters
All tables share the same free parameters:
| Parameter | Default (Range) | Description |
|---|---|---|
| PhoIndex | 1.6 – 2.4 | Photon index Γ of the input cutoff power-law continuum |
| NHeq | log range 22.0 – 25.5 | Equatorial hydrogen column density of the dusty torus |
| CFtor (r/R) | 0.1 – 0.9 | Covering factor of the torus; ratio of inner cutout radius r to outer radius R. CFtor = sin(φ) |
| NHpol | log range 22.0 – 24.0 | Hydrogen column density of the polar hollow cone, measured along the inner cone surface |
| Inclination | 1 – 89 | Viewing angle θ of the system (1 = face-on, 89 = edge-on) |
| z | 0 – 5 | Redshift |
| norm | 0 – 10e20 | Photon flux of the input continuum at 1 keV (ph keV-1 cm-2 s-1) |
Note on the polar cone opening angle:
The hollow cone is collimated by the torus. Its inner boundary angle is set to ξ_max = φ + 1° (to avoid overlap), where φ = arcsin(CFtor). The cone has a fixed angular width of 10°, so its outer boundary is ξ_o = ξ_max + 10°. The cone column density NHpol is a free parameter independent of CFtor.
Line-of-sight calculation
A tool, reflex-los-calculator, is provided here to get the line-of-sight NH for both RXToPo and RXagn
Usage in XSPEC
Typical usage with the ALL table:
model tbabs * atable{RXagn1_all.mod}
For greater flexibility, use the reprocessed component with additional soft emission and line components:
model tbabs * (atable{RXagn1_rprc.mod} + apec + zgauss)
