Tracing Evolution in Massive Protostellar Objects (TEMPO) -- I: Fragmentation and emission properties of massive star-forming clumps in a luminosity limited ALMA sample
A. Avison, G. A. Fuller, N. Asabre Frimpong +16
The role of massive ( 8M) stars in defining the energy budget and chemical enrichment of the interstellar medium in their host galaxy is significant. In this first…
The GUAPOS project:III. Characterization of the O- and N-bearing complex organic molecules content and search for chemical differentiation
C. Mininni, M. T. Beltrán, L. Colzi +8
The G31.41+0.31 Unbiased ALMA sPectral Observational Survey (GUAPOS) project targets the hot molecular core (HMC) G31.41+0.31 (G31), to unveil the complex chemistry of one of the m…
The SOUL view of IRAS20126+4104. Kinematics and variability of the H jet from a massive protostar
F. Massi, A. Caratti o Garatti, R. Cesaroni +20
We exploit the increased sensitivity of the recently installed AO SOUL at the LBT to obtain new high-spatial-resolution NIR images of the massive young stellar object IRAS20126+410…
N-bearing complex organics toward high-mass protostars: Constant ratios pointing to formation in similar pre-stellar conditions across a large mass range
P. Nazari, J. D. Meijerhof, M. L. van Gelder +10
No statistical study of COMs toward a large sample of high-mass protostars with ALMA has been carried out so far. We aim to study six N-bearing species: CHCN, HNCO, NHCHO,…
Methanol deuteration in high-mass protostars
M. L. van Gelder, J. Jaspers, P. Nazari +6
The deuteration of molecules forming in the ices such as methanol (CHOH) is sensitive to the physical conditions during their formation in dense cold clouds and can be probed t…
CHEMOUT: CHEMical complexity in star-forming regions of the OUTer Galaxy. II. Methanol formation at low metallicity
F. Fontani, A. Schmiedeke, A. Sanchez-Monge +8
The outer Galaxy is an environment with metallicity lower than the Solar one and, because of this, the formation and survival of molecules in star-forming regions located in the in…
CHEMOUT: CHEMical complexity in star-forming regions of the OUTer Galaxy. I. Organic molecules and tracers of star-formation activity
F. Fontani, L. Colzi, L. Bizzocchi +8
The outer Galaxy is an environment with metallicity lower than the Solar one. Because of this, the formation and survival of molecules in star-forming regions located in the inner…
Importance of source structure on complex organics emission. I. Observations of CHOH from low-mass to high-mass protostars
M. L. van Gelder, P. Nazari, B. Tabone +9
Complex organic molecules (COMs) are often observed toward embedded Class 0 and I protostars. However, not all Class 0 and I protostars exhibit COMs emission. In this work, variati…
The sharp ALMA view of infall and outflow in the massive protocluster G31.41+0.31
M. T. Beltrán, V. M. Rivilla, R. Cesaroni +15
Context. To better understand the formation of high-mass stars, it is fundamental to investigate how matter accretes onto young massive stars, how it is ejected, and how all this d…
Disks around O-type young stellar objects
Maite Beltrán
Accretion disks are one of the key ingredients of the star formation process. They redistribute angular momentum and, in the case of high-mass stars (M > 8Msun), disks would reliev…
Wide Bandwidth Considerations for ALMA Band 2
Tony Mroczkowski, Carlos De Breuck, Ciska Kemper +9
One of the main considerations in the ALMA Development Roadmap for the future of operations beyond 2030 is to at least double its on-sky instantaneous bandwidth capabilities. Thank…
Resolving the Structure and Kinematics of the Youngest HII Regions and Radio Jets from Young Stellar Objects
Roberto Galván-Madrid, Maite Beltrán, Adam Ginsburg +4
In this contribution we explore the new science that a Next Generation Very Large Array (ngVLA) would be able to perform on the topics of the youngest HII regions and (proto)stella…
Properties of Hi-GAL clumps in the inner Galaxy]{The Hi-GAL compact source catalogue. I. The physical properties of the clumps in the inner Galaxy ()
D. Elia, S. Molinari, E. Schisano +83
Hi-GAL is a large-scale survey of the Galactic plane, performed with Herschel in five infrared continuum bands between 70 and 500 m. We present a band-merged catalogue of spatia…
