Determination of kinematic distances of WISE & SMGPS H II regions in the Galactic plane using SEDIGISM cloud association
Moses Langa, Mark Thompson, Andrew Rigby +7
One of the fundamental requirements for studying and understanding Galactic structure and massive star formation is accurate distances to H II regions. However, most distance assig…
The Influential Roles of Gravity, Turbulence, and Magnetic Fields in Shaping the Physical Evolution of Dense Massive Clumps
Moses Onyemaechi Asogwa, Seblu Humne Negu, Gemechu Muleta Kumssa +1
We explore the roles of the three competitors, namely, gravity, turbulence, and magnetic fields, in controlling star formation (SF) within dense, massive clumps identified in the A…
H II regions and supernova remnants associated with molecular clouds: A pilot study with the SARAO MeerKAT Galactic Plane Survey
Moses O. Langa, Mark A. Thompson, Andrew J. Rigby +5
Massive stars (mass beyond 8 solMass) release vast amounts of energy into the interstellar medium through their stellar winds, photoionising radiation and supernova explosions. The…
Investigating star formation scenarios in the Milky Way using YSO distributions -- A pilot study
Annarien G. Headley, James O. Chibueze
We investigated the distributions of classified young stellar object (YSO) in nine star-forming regions associated with Hii regions, namely Sh2-22, Sh2-19, Sh2-17, M16, M8, IC5070,…
A misaligned protostellar disk fed by gas streamers in a barred spiral-like massive dense core
Xiaofeng Mai, Tie Liu, Xunchuan Liu +42
High-mass stars, born in massive dense cores (MDCs), profoundly impact the cosmic ecosystem through feedback processes and metal enrichment, yet little is known about how MDCs asse…
The SARAO MeerKAT Galactic Plane Survey extended source catalogue
C. Bordiu, S. Riggi, F. Bufano +18
We present a catalogue of extended radio sources from the SARAO MeerKAT Galactic Plane Survey (SMGPS). Compiled from 56 survey tiles and covering approximately 500 deg across t…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- XIX. The origin of SiO emission
Rong Liu, Tie Liu, Izaskun Jiménez-Serra +23
The production of silicon monoxide (SiO) can be considered as a fingerprint of shock interaction. In this work, we use high-sensitivity observations of the SiO (2-1) and HCO…
Supernova Remnant Candidates Discovered by the SARAO MeerKAT Galactic Plane Survey
L. D. Anderson, F. Camilo, Timothy Faerber +13
Context. Sensitive radio continuum data could remove the difference between the number of known supernova remnants (SNRs) in the Galaxy compared to that expected, but due to confus…
Identifying the Mechanisms of Water Maser Variability During the Accretion Burst in NGC6334I
Jakobus M. Vorster, James O. Chibueze, Tomoya Hirota +5
HMYSOs gain most of their mass in short bursts of accretion. Maser emission is an invaluable tool in discovering and probing accretion bursts. We observed the 22 GHz water maser re…
The VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey: Completion of the observations and legacy
R. K. Saito, M. Hempel, J. Alonso-García +143
The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from . Upon its conclusion, the c…
MeerKAT and ALMA view of the AGAL045.804-0.356 clump
Mavis Seidu, J. O. Chibueze, Gary A. Fuller +2
This study presents a detailed analysis of the GAL045.804-0.356 massive star-forming clump. A high-angular resolution and sensitivity observations were conducted using MeerKAT at 1…
Searching for globular clusters in the inner halo of the Circinus galaxy
C. O. Obasi, M. Gomez, D. Minniti +3
In this study, we search for Globular Clusters (GCs) in the inner halo of the Circinus galaxy using a combination of observational data. Our dataset includes observations from the…
Direct observational evidence of the multi-scale, dynamical mass accretion toward a high-mass star forming hub-filament system
Dongting Yang, Hong-Li Liu, Anandmayee Tej +28
There is growing evidence that high-mass star formation and hub-filament systems (HFS) are intricately linked. The gas kinematics along the filaments and the forming high-mass star…
Ammonia mapping observations of the Galactic infrared bubble N49: Three NH clumps along the molecular filament
Mikito Kohno, James O. Chibueze, Ross A. Burns +9
We have carried out the NH and mapping observations toward the Galactic infrared bubble N49 (G28.83-0.25) using the Nobeyama 45 m telescope. Three…
The globular cluster system of the nearest Seyfert II galaxy Circinus
C. Obasi, M. Gómez, D. Minniti +7
Context. The globular cluster (GC) system of Circinus galaxy has not been probed previously partly because of the location of the galaxy at - 3.8 Galactic latitude which su…
The evolution of the H2O maser emission in the accretion burst source G358.93-0.03
