# Multifrequency study of a new Hybrid Morphology Radio Source

## TL;DR

This paper reports the discovery and detailed multi-frequency analysis of a new Hybrid Morphology Radio Source, providing insights into the intrinsic bimodal nature of HyMoRS and discussing the limitations of morphology-based classification.

## Contribution

It presents the first detailed multi-frequency radio and X-ray study of a newly discovered HyMoRS, advancing understanding of their intrinsic properties and classification challenges.

## Key findings

- HyMoRS are intrinsically bimodal in spectral and polarisation properties
- Morphological classification alone is unreliable for HyMoRS
- Discovery of a new HyMoRS with comprehensive multi-frequency data

## Abstract

Hybrid Morphology Radio Sources (HyMoRS) are a class of radio galaxies having the lobe morphology of a Fanaroff-Riley (FR) type I on one side of the active nucleus and of a FR type II on the other. The origin of the different morphologies between FR I and FR II sources has been widely discussed in the past 40 years, and HyMoRS may be the best way to understand whether this dichotomy is related to the intrinsic nature of the source and/or to its environment. However, these sources are extremely rare (<1% of radio galaxies) and only for a few of them a detailed radio study, that goes beyond the morphological classification, has been conducted. In this paper we report the discovery of one new HyMoRS; we present X-ray and multi-frequency radio observations. We discuss the source morphological, spectral and polarisation properties and confirm that HyMoRS are intrinsically bimodal with respect to these observational characteristics. We notice that HyMoRS classification based just on morphological properties of the source is hazardous.
