# MAGIC and Fermi-LAT gamma-ray results on unassociated HAWC sources

## TL;DR

This study combines observations from HAWC, MAGIC, and Fermi-LAT to analyze three unassociated gamma-ray sources, revealing insights into their spatial extension, spectral properties, and potential pulsar wind nebula origins.

## Contribution

First joint analysis of HAWC, MAGIC, and Fermi-LAT data on unassociated sources, providing constraints on their size, spectrum, and nature.

## Key findings

- No significant detection in HE and VHE regimes.
- Minimum extension and spectral hardness are required for one source.
- Pulsar wind nebula hypothesis is explored.

## Abstract

The HAWC Collaboration released the 2HWC catalog of TeV sources, in which 19 show no association with any known high-energy (HE; E > 10 GeV) or very-high-energy (VHE; E > 300 GeV) sources. This catalog motivated follow-up studies by both the MAGIC and Fermi-LAT observatories with the aim of investigating gamma-ray emission over a broad energy band. In this paper, we report the results from the first joint work between HAWC, MAGIC and Fermi-LAT on three unassociated HAWC sources: 2HWC J2006+341, 2HWC J1907+084* and 2HWC J1852+013*. Although no significant detection was found in the HE and VHE regimes, this investigation shows that a minimum 1 degree extension (at 95% confidence level) and harder spectrum in the GeV than the one extrapolated from HAWC results are required in the case of 2HWC J1852+013*, while a simply minimum extension of 0.16 degrees (at 95% confidence level) can already explain the scenario proposed by HAWC for the remaining sources. Moreover, the hypothesis that these sources are pulsar wind nebulae is also investigated in detail.
