# The e-ASTROGAM space mission: a major step forward for supernova physics

## TL;DR

The e-ASTROGAM space mission aims to significantly advance supernova physics and cosmic ray studies by providing unprecedented gamma-ray observations and polarization data in the medium-energy range.

## Contribution

It introduces a new gamma-ray observatory with enhanced capabilities to study supernovae and cosmic rays, expanding the known gamma-ray source population.

## Key findings

- Potential to increase known gamma-ray sources by over tenfold
- Ability to measure gamma-ray polarization for many sources
- Enhanced understanding of supernova mechanisms and cosmic ray origins

## Abstract

e-ASTROGAM is a gamma-ray observatory operating in a broad energy range, 0.15 MeV - 3 GeV, recently proposed as the M5 Medium-size mission of the European Space Agency. It has the potential to revolutionize the astronomy of medium-energy gamma-rays by increasing the number of known sources in this domain by more than an order of magnitude and providing gamma-ray polarization information for many of these sources. In these proceedings, we discuss the expected capacity of the mission to study the physics of supernovae, both thermonuclear and core-collapse, as well as the origin of cosmic rays in supernova shocks.
