Orbital motion and dynamical mass of the complex periodic variable binary system 2MASS J05082729-2101444
S. Curiel, G. N. Ortiz-León, V. J. S. Béjar +22
We used very long baseline interferometry to constrain the orbit of the binary system 2MASS J05082729-2101444. We observed the system with the VLBA in three epochs at a frequency o…
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…
Survey of (sub)mm water masers in low-mass star-forming regions
P. K. Humire, C. Goddi, G. N. Ortiz-León +2
Water masers are common in star-forming regions (SFRs), with the 22.235 GHz transition widely detected in both high- and low-mass protostars. In contrast, (sub)millimeter water mas…
Dynamical mass of the Serpens intermediate-mass young stellar system EC\,95 with DYNAMO--VLBA
Jazmín Ordóñez-Toro, Sergio A. Dzib, Laurent Loinard +8
We present dynamical mass measurements, obtained from multi-epoch Very Long Baseline Interferometry (VLBI) observations, for the young multiple stellar system EC\,95, located in th…
VLBA Detections in the Oph-S1 Binary System near Periastron Confirmation of its Orbital Elements and Mass
Jazmín Ordóñez-Toro, Sergio A. Dzib, Laurent Loinard +7
Oph-S1 is the most luminous and massive stellar member of the nearby Ophiuchus star-forming region. Previous Very Long Baseline Array (VLBA) observations have shown it to be an int…
A multi-frequency study of sub-parsec jets with the Event Horizon Telescope
Jan Röder, Maciek Wielgus, Andrei P. Lobanov +287
The 2017 observing campaign of the Event Horizon Telescope (EHT) delivered the first very long baseline interferometry (VLBI) images at the observing frequency of 230 GHz, leading…
First detection of the 1) methanol maser transitions at and
Pedro K. Humire, Gisela N. Ortiz-León, Antonio Hernández-Gómez +3
Class\,I methanol masers provide sensitive information about the shocked environment around star-forming regions. Among the brightest Class~I methanol masers, we have those in the…
Detection and characterization of detached tidal dwarf galaxies
Javier Zaragoza-Cardiel, Beverly J. Smith, Mark G. Jones +7
Tidal interactions between galaxies often give rise to tidal tails, which can harbor concentrations of stars and interstellar gas resembling dwarf galaxies. Some of these tidal dwa…
Dynamical mass of the Ophiuchus intermediate-mass stellar system S1 with DYNAMO-VLBA
Jazmín Ordóñez-Toro, Sergio A. Dzib, Laurent Loinard +8
We report dynamical mass measurements of the individual stars in the most luminous and massive stellar member of the nearby Ophiuchus star-forming region, the young tight binary sy…
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…
Protonated hydrogen cyanide as a tracer of pristine molecular gas
Y. Gong, F. J. Du, C. Henkel +11
Protonated hydrogen cyanide, HCNH, plays a fundamental role in astrochemistry because it is an intermediary in gas-phase ion-neutral reactions within cold molecular clouds. H…
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…
Comparison of Polarized Radiative Transfer Codes used by the EHT Collaboration
Cora Prather, Jason Dexter, Monika Moscibrodzka +270
Interpretation of resolved polarized images of black holes by the Event Horizon Telescope (EHT) requires predictions of the polarized emission observable by an Earth-based instrume…
A global view on star formation: The GLOSTAR Galactic plane survey. VII. Supernova remnants in the Galactic longitude range
R. Dokara, Y. Gong, W. Reich +19
Context. While over 1000 supernova remnants (SNRs) are estimated to exist in the Milky Way, only less than 400 have been found to date. In the context of this apparent deficiency,…
A global view on star formation: The GLOSTAR Galactic plane survey. VI. Radio Source Catalog II: and , VLA B-configuration
S. A. Dzib, A. Y. Yang, J. S. Urquhart +20
As part of the GLOSTAR survey we have used the VLA in its B-configuration to observe the part of the Galactic plane between longitudes of 28d and 36d and latitudes from -1d to +1d…
