Erosion of a dense molecular core by a strong outflow from a massive protostar

J. A. López-Vázquez, M. Fernández-López, J. M. Girart +6

We present Atacama Large Millimeter/submillimeter Array Band 3 observations of NH (1-0) and CHCN (5-4), as well as Band 7 observations of the HCO molecular line emi…

ALMA-IMF XVII -- Census and lifetime of high-mass prestellar cores in 14 massive protoclusters

M. Valeille-Manet, S. Bontemps, T. Csengeri +24

High-mass prestellar cores are extremely rare. The search for such objects has long been hindered by small sample sizes, leading to large uncertainties in their lifetimes and the c…

ngVLA Synthetic Observations of Ionized Gas in Massive Protostars

Jesús M. Jáquez-Domínguez, Roberto Galván-Madrid, Alfonso Trejo-Cruz +11

Massive star formation involves significant ionization in the innermost regions near the central object, such as gravitationally trapped H II regions, jets, ionized disks, or winds…

ALMA-IMF XVI: Mass-averaged temperature of cores and protostellar luminosities in the ALMA-IMF protoclusters

F. Motte, Y. Pouteau, T. Nony +34

ALMA-IMF imaged 15 massive protoclusters down to a resolution of of 2 kau scales, identifying about 1000 star-forming cores. The mass and luminosity of these cores, which are funda…

Next Generation Very Large Array Memo #122: Characterization of the synthesized beam with and without MID antennas in Mexico

Alfonso Trejo-Cruz, Roberto Galván-Madrid, Carlos Carrasco-González +5

Synthesized beam (PSF) synthetic observations with and without the antennas in Mexico are analyzed. For a simple continuum observing setup, we generated visibility files and their…
