Broad N2H+ emission towards the protostellar shock L1157-B1
C. Codella, S. Viti, C. Ceccarelli +8
We present the first detection of N2H+ towards a low-mass protostellar outflow, namely the L1157-B1 shock, at about 0.1 pc from the protostellar cocoon. The detection was obtained…
A gas-rich AGN near the centre of a galaxy cluster at z ~ 1.4
V. Casasola, L. Magrini, F. Combes +4
The formation of the first virialized structures in overdensities dates back to ~9 Gyr ago, i.e. in the redshift range z ~ 1.4 - 1.6. Some models of structure formation predict tha…
Physical properties of high-mass clumps in different stages of evolution
A. Giannetti, J. Brand, A. Sanchez-Monge +6
(Abridged) Aims. To investigate the first stages of the process of high-mass star formation, we selected a sample of massive clumps previously observed with the SEST at 1.2 mm and…
Properties of dense cores in clustered massive star-forming regions at high angular resolution
Alvaro Sanchez-Monge, Aina Palau, Francesco Fontani +8
We aim at characterising dense cores in the clustered environments associated with massive star-forming regions. For this, we present an uniform analysis of VLA NH3(1,1) and (2,2)…
High angular resolution observations towards OMC-2 FIR 4: Dissecting an intermediate-mass protocluster
A. López-Sepulcre, V. Taquet, Á. Sánchez-Monge +9
OMC-2 FIR 4 is one of the closest known young intermediate-mass protoclusters, located at a distance of 420 pc in Orion. This region is one of the few where the complete 500-2000 G…
The Dynamics of Massive Starless Cores with ALMA
Jonathan C. Tan, Shuo Kong, Michael J. Butler +2
How do stars that are more massive than the Sun form, and thus how is the stellar initial mass function (IMF) established? Such intermediate- and high-mass stars may be born from r…
