## TL;DR

This paper identifies 24 new blazar candidates by analyzing gamma-ray photon clusters from the 9Y-MST catalogue at energies above 10 GeV, using multi-wavelength data to confirm their nature.

## Contribution

The study introduces a novel method for identifying blazar candidates through gamma-ray cluster analysis and multi-wavelength association, expanding the catalog of potential blazars.

## Key findings

- 24 new blazar candidates identified
- 13 candidates also in the 4FGL catalogue
- Multi-wavelength analysis supports blazar nature

## Abstract

We present a list of 24 new blazar candidates selected in a search for possible counterparts of spatial clusters of gamma-ray photons in the recent 9Y-MST catalogue, at energies higher than 10 GeV and at Galactic latitudes higher than 20 degrees. 13 of these clusters are also included the preliminary release of the 4FGL catalogue of gamma-ray sources. The search for possible counterparts is based on the possible associations of the clusters with radio sources within a circle having a radius of 6 arcmin. We then investigated the possible optical or mid-IR associations of these sources, checking if they show some properties typical of new blazar candidates.
