"description": "<p>Much progress has been made to understand the formation of massive stars in last the decades. One of the ways to understand the massive star formation is to search for similar phenomenon which are observed in low-mass star forming regions. Currently, disks and outflows are observed in the massive star forming regions similarly to what is seen in low mass star forming regions. The goal of this study is to search for radio jets, which are directly related to the ejection of material and the presence of outflows, and derive their properties, by establishing the morphology of the 1.3 cm continuum emission and the spectral index between 1.3 cm and 6 cm. Thermal radio jets are commonly found in the first stages of the formation of low-mass stars and appear to power larger-scale molecular outflows. For this purpose, we selected a sample of 18 targets with a high probability of association with thermal jets using the Very Large Array (VLA) and they are analyzed. Although 189 strong and weak sources were detected in the entire maps only ten sources are detected at both requencies. Out of these ten objects, we have identified four sources that can be classified as thermal radio jets associated with high-mass stars. Addition to this, two sources are classified as non-thermal radio jets and remaining four sources are classified as HII regions.</p>",
