# Evidence of Outflow Induced Soft Lags of Galactic Black Holes

## TL;DR

This paper investigates the origin of soft lags in Galactic black holes, proposing that outflows or jets influence disk morphology and contribute to observed soft lag phenomena, based on correlations with radio intensities.

## Contribution

It introduces a potential link between outflows/jets and soft lag variations in Galactic black holes, highlighting a new aspect of their physical mechanisms.

## Key findings

- Correlation between radio intensities and soft lags.
- Outflows or jets may alter disk morphology affecting lag behavior.
- Soft lags are influenced by outflow-related changes in the accretion disk.

## Abstract

The nature of lag variation of Galactic black holes remains enigmatic mostly because of nonlinear and non-local physical mechanisms which contribute to the lag of the photons coming from the region close to the central black holes. One of the widely accepted major sources of the hard lag is the inverse Comptonization mechanism. However, the exact reason or reasons for soft lags is yet to be identified. In this paper, we report a possible correlation between radio intensities of several outbursting Galactic black hole candidates and amounts of soft lag. The correlation suggests that the presence of major outflows or jets also change the disk morphology along the line of sight of the observer which produces soft lags.
