Clouds, filaments, and protostars: TheHerschel Hi-GAL Milky Way
- S. Molinari, B. Swinyard, Q. Zhang
- Physics
- 18 May 2010
We present the first results from the science demonstration phase for the Hi-GAL survey, the Herschel key program that will map the inner Galactic plane of the Milky Way in 5 bands. We outline our…

- PhysicsAstronomy & Astrophysics
- 9 October 2018
We present high angular resolution (~0.2″) continuum and molecular emission line Atacama Large Millimeter/sub-millimeter Array (ALMA) observations of G17.64+0.16 in Band 6 (220−230 GHz) taken as part…
Formation of ethylene glycol and other complex organic molecules in star-forming regions
- V. Rivilla, M. Beltr'an, R. Cesaroni, F. Fontani, C. Codella, Q. Zhang
- Physics
- 26 August 2016
Context. The detection of complex organic molecules related with prebiotic chemistry in star-forming regions allows us to investigate how the basic building blocks of life are formed. Aims. Ethylene…
Survey of intermediate/high mass star-forming regions at centimeter and millimeter wavelengths
- 'A. S'anchez-Monge, A. Palau, Spain.
- Physics
- 21 February 2008
Aims. The goal of this work is to characterize the millimeter and centimeter properties of intermediate/high mass young stellar objects (YSOs) to search for any evolutionary trends. Methods. We…
A necklace of dense cores in the high-mass star forming region G35.20−0.74 N: ALMA observations
- 'A. S'anchez-Monge, M. Beltr'an, E. Schisano
- Physics
- 16 June 2014
Context. The formation process of high-mass stars (with masses >8 M_⊙) is still poorly understood, and represents a challenge from both the theoretical and observational points of view. The advent of…
Dissecting a hot molecular core: the case of G31.41+0.31
- R. Cesaroni, M. Beltr'an, U. Victoria
- Physics
- 14 July 2011
Context. The role of disks in the formation of high-mass stars is still a matter of debate but the detection of circumstellar disks around O-type stars would have a profound impact on high-mass star…
Binary system and jet precession and expansion in G35.20-0.74N
- M. Beltr'an, R. Cesaroni, U. Porto
- Physics
- 13 June 2016
Context. ALMA observations of the high-mass star-forming region G35.20-0.74N have revealed the presence of a Keplerian disk in core B rotating about a massive object of 18 Msun, as computed from the…
Phosphorus-bearing molecules in the Galactic Center
- V. Rivilla, I. Jim'enez-Serra, M. Beltr'an
- Physics
- 19 December 2017
Phosphorus (P) is one of the essential elements for life due to its central role in biochemical processes. Recent searches have shown that P-bearing molecules (in particular PN and PO) are present in…
ALMA resolves the hourglass magnetic field in G31.41+0.31
- M. Beltr'an, M. Padovani, C. F. A. HarvardSmithsonian
- PhysicsAstronomy & Astrophysics
- 5 August 2019
Context. Submillimeter Array (SMA) 870 μm polarization observations of the hot molecular core G31.41+0.31 revealed one of the clearest examples up to date of an hourglass-shaped magnetic field…
SEDIGISM: Structure, excitation, and dynamics of the inner Galactic interstellar medium
- F. Schuller, T. Csengeri, A. Zavagno
- Physics
- 17 January 2017
Context. The origin and life-cycle of molecular clouds are still poorly constrained, despite their importance for understanding the evolution of the interstellar medium. Many large-scale surveys of…
