Abstract:

We investigated influence of cosmological GRB on the surrounding interstellar medium. It was shown that $\gamma$-radiation from the burst heats interstellar gas to the temperatures >104 K up to the distance $\sim10$ pc. For high density ISM, optical and UV radiation of the heated, gas can be observed on the Earth several years as a GRB's counterpart.

Key words: gamma-rays: bursts
