# Accretion models for LLAGNs: Model Parameter Estimation and Prediction of their Detectibility

## TL;DR

This paper develops a theoretical ADAF plus jet model to interpret EHT observations of supermassive black holes, estimating parameters and predicting their detectability through spectral and spatial emission profiles.

## Contribution

It introduces a combined ADAF and jet model for LLAGNs, enabling parameter estimation and predictions of EHT resolvability based on spectral and spatial data.

## Key findings

- Model fits observed spectral energy distributions.
- Predicted radial emission profiles inform EHT detectability.
- Parameter estimates enhance understanding of accretion and jet physics.

## Abstract

The Event Horizon Telescope (EHT) provides a unique opportunity to probe the physics of supermassive black holes through Very Large Baseline Interferometry (VLBI), such as the existence of the event horizon, the accretion processes as well as jet formation. We build a theoretical model which includes an Advection Dominated Accretion Flow (ADAF) and a simple radio jet outflow. The predicted spectral energy distribution (SED) of this model is compared to observations to get the best estimates of the model parameters. Also the model-predicted radial emission profiles at different frequency bands can be used to predict whether the inflow can be resolved by the EHT.
