First detection of glycolaldehyde outside the Galactic Center
Glycolaldehyde is the simplest of the monosaccharide sugars and is directly linked to the origin of life. We report on the detection of glycolaldehyde (CH2OHCHO) toward the hot molecular coreExpand
Infall of gas as the formation mechanism of stars up to 20 times more massive than the Sun
Observations of an ammonia line towards a high-mass star forming region conclude that the gas is falling inwards towards a very young star of ∼20M[circdot], in line with theoretical predictions of non-spherical accretion. Expand
Rotating toroids in G10.62–0.38, G19.61–0.23, and G29.96–0.02
Context. In recent years, we have detected clear evidence of rotation in more than 5 hot molecular cores (HMCs). Their identification is confirmed by the fact that the rotation axes are parallel toExpand
A detailed study of the rotating toroids in G31.41+0.31 and G24.78+0.08
We present the results of high angular resolution millimeter observations of gas and dust toward G31.41+0.31 and G24.78+0.08, two high-mass star forming regions where four rotating massive toroidsExpand
First Detection of Water Vapor in a Pre-stellar Core
Water is a crucial molecule in molecular astrophysics as it controls much of the gas/grain chemistry, including the formation and evolution of more complex organic molecules in ices. Pre-stellarExpand
ALMA observations of polarized emission toward the CW Tau and DG Tau protoplanetary disks: constraints on dust grain growth and settling
We present polarimetric data of CW Tau and DG Tau, two well-known Class II disk/jet systems, obtained with the Atacama Large Millimeter/submillimeter Array at 870 $\mu$m and 0."2 average resolution.Expand
The ALMA view of the protostellar system HH212 - The wind, the cavity, and the disk
Context: Because it is viewed simply edge-on, the HH212 protostellar system is an ideal laboratory for studying the interplay of infall, outflow, and rotation in the earliest stages of low-mass starExpand
First results from the CALYPSO IRAM-PdBI survey - II. Resolving the hot corino in the Class 0 protostar NGC 1333-IRAS2A
We investigate the origin of complex organic molecules (COMs) in the gas phase around the low-mass Class~0 protostar NGC1333-IRAS2A, to determine if the COM emission lines trace an embedded disk,Expand
Molecular outflows and hot molecular cores in G24.78+0.08 at sub-arcsecond angular resolution
Context. This study is part of a large project to study the physics of accretion and molecular outflows towards a selected sample of high-mass star-forming regions that show evidence of infall andExpand
Evolution and excitation conditions of outflows in high-mass star-forming regions
Theoretical models suggest that massive stars form via disk-mediated accretion, with bipolar outflows playing a fundamental role. A recent study toward massive molecular outflows has revealed aExpand
