Revisiting G29.862–0.0044: A jet cavity disrupted by an outflow in a likely young stellar object wide binary system Open
Aims . A few years ago, we investigated the massive young stellar object (MYSO) G29.862–0.0044 (YSO-G29), an intriguing star-forming region at a distance of 6.2 kpc. Although the typical disc-jet scenario was proposed to explain the observ…

A comprehensive analysis towards the Fermi-LAT source 4FGL J1846.9–0227: jets of a protoplanetary nebula producing γ-rays? Open
Most of the $\gamma$-ray sources in the Fermi-LAT 14-yr source catalogue are associated with pulsars and blazars. However, unveiling the nature of the still unassociated $\gamma$-ray sources is important for the understanding of high energ…

Understanding the chemistry of the young stellar object G29.862-0.0044 Open
In previous works, we have investigated the star-forming region G29.96$-$0.02 where the massive young stellar object (MYSO) G29.862$-$0.0044 (hereafter G29) is embedded in a hot molecular core. In one of them, of multiwavelength nature, us…

Radio and infrared study of the supernova remnant candidate HESS J1912+101 Open
Aims. We provide new insights into the γ -ray emission from HESS J1912+101, a TeV supernova remnant candidate probably associated with the radio pulsar PSR J1913+1011. Methods. We obtained new observations at 1.5 GHz using the VLA in the D…

Radio study of the extended TeV source VER J1907+062 Open
This paper aims to provide new insights on the origin of the TeV source VER J1907+062 through new high-quality radio observations. We used the Karl G. Jansky Very Large Array (VLA) to observe the whole extension of VER J1907+062 at 1.5 GHz…

New X-ray observations toward PSR J1826-1256 Open
We present the results of XMM-Newton observations toward the pulsar PSR J1826$-$1256, which lies at 5$^{\prime}$.4 from the centroid of the TeV source HESS J1826$-$130. These data show an elongated nebula with the pulsar located in the nor…

A new study towards PSR J1826–1334 and PSR J1826–1256 in the region of HESS J1825–137 and HESS J1826–130 Open
Aims. The goal of this paper is to detect synchrotron emission from the relic electrons of the crushed pulsar wind nebula (PWN) HESS J1825−137 and to investigate the origin of the γ -ray emission from HESS J1826−130. Methods. The study of …

Study of the molecular and ionized gas in a possible precursor of an ultra-compact H II region Open
We study the molecular and the ionized gas in a possible precursor of an UC\nHII region to contribute to the understanding of how high-mass stars build-up\ntheir masses once they have reached the zero-age main secuence. We carried out\nmol…

The molecular environment of the pillar-like features in the H ii region G46.5–0.2 Open
At the interface of H II regions and molecular gas, peculiar structures appear, some of them with pillar-like shapes. Understanding their origin is important for characterizing triggered star formation and the impact of massive stars on th…

The southern molecular environment of SNR G18.8+0.3 Open
\n Aims. In a previous paper we investigated the molecular environment toward the eastern border of the supernova remnant (SNR) G18.8+0.3. Continuing with the study of the surroundings of this SNR, we now focus on its southern border, whic…
