Variability of Sagittarius A* at 3 GHz on minute-scale with MeerKAT
K. Kaur, I. Rammala-Zitha, A. Basu +21
The supermassive black hole Sagittarius A* (Sgr A*) exhibits temporal and spectral variability across the electromagnetic spectrum. However, variability at radio frequencies below…
Massive star formation at the Galactic crossroads: Insights from G358.69+0.03 in the Galactic center
A. Cheema, V. S. Veena, K. M. Menten +7
We investigated the high-mass star formation activity in a subregion of the Sagittarius E star-forming complex, centered at (l,b) = (358.69 deg, 0.03 deg), where infrared and radio…
Exploring the interplay between molecular and ionized gas in HII regions
S. Khan, A. M. Jacob, M. R. Rugel +8
We aim to constrain the kinetic temperature and H volume density of massive star-forming clumps associated with HII regions using multiple para-HCO transitions. In addition…
A global view on star formation: The GLOSTAR Galactic plane survey XII. Effelsberg's continuum view and data release
Y. Gong, W. Reich, M. R. Rugel +24
Extended radio continuum emission and its linear polarization play a key role in probing large-scale structures of synchrotron and free-free emission in the Milky Way. Despite the…
Inferring the efficiency of convective-envelope overshooting in Red Giant Branch stars
Lorenzo Briganti, Marco Tailo, Edoardo Ceccarelli +6
The understanding of mixing processes in stars is crucial for improving our knowledge of the chemical abundances in stellar photospheres and of their variation with evolutionary ph…
Faint absorption of the ground state hyperfine-splitting transitions of hydroxyl at 18 cm in the Galactic Disk
M. R. Rugel, H. Beuther, J. D. Soler +15
The interstellar hydride hydroxyl (OH) is a potential tracer of CO-dark molecular gas. We present new absorption line observations of OH at 18-cm wavelength towards four continuum…
SCOTCH III: Complete search for Hypercompact HII regions in the fourth quadrant
A. L. Patel, J. S. Urquhart, A. Y. Yang +7
We present high-frequency (18-24 GHz) radio continuum observations towards 335 methanol masers, excellent signposts for young, embedded high-mass protostars. These complete the sea…
SOFIA FIFI-LS spectroscopy of DR21 Main: energetics of the spatially-resolved outflow from a high-mass protostar
A. Karska, M. Figueira, A. Mirocha +12
Massive star formation is associated with energetic processes that may influence the physics and chemistry of parental molecular clouds and impact galaxy evolution. The high-mass p…
A global view on star formation: The GLOSTAR Galactic plane survey. XI. Radio source catalog IV: , and
S. -N. X. Medina, S. A. Dzib, J. S. Urquhart +17
The GLOSTAR survey studies star formation with the VLA and the Effelsberg 100m telescope in the Galactic plane (-2d<l<60d; |b|<1d) and the Cygnus X region with unprecedented sensit…
A global view on star formation: The GLOSTAR Galactic plane survey X. Galactic HII region catalog using radio recombination lines
S. Khan, M. R. Rugel, A. Brunthaler +17
Studies of Galactic HII regions are of crucial importance for studying star formation and the evolution of the interstellar medium. Gaining an insight into their physical character…
A global view on star formation: The GLOSTAR Galactic plane survey. IX. Radio Source Catalog III: 2<l<28, 36<l<40, 56<l<60 and |b|<1, VLA B-configuration
A. Y. Yang, S. A. Dzib, J. S. Urquhart +20
As part of the GLOSTAR (GLObal view of STAR formation in the Milky Way) survey, we present the high-resolution continuum source catalog for the regions (l = 2-28, 36-40, 56-60, &|b…
A global view on star formation: The GLOSTAR Galactic plane survey VIII. Formaldehyde absorption in Cygnus~X
Y. Gong, G. N. Ortiz-León, M. R. Rugel +21
Cygnus X is one of the closest and most active high-mass star-forming regions in our Galaxy, making it one of the best laboratories for studying massive star formation. As part of…
