The interstellar medium is characterized by a rich and diverse chemistry. Many of its
complex organic molecules are proposed to form through radical chemistry in icy grain …

An observational review is provided of the properties of accretion disks around young stars.
It concerns the primordial disks of intermediate-and high-mass young stellar objects in …

Spectral line surveys are an indispensable tool for exploring the physical and chemical
evolution of astrophysical environments due to the vast amount of data that can be obtained …

Aims. The TOPGöt project studies a sample of 86 high-mass star-forming regions in different
evolutionary stages from starless cores to ultra compact HII regions. The aim of the survey is …

Experimental and theoretical studies have been carried out to demonstrate the selective
generation of two different C2H3N+ isomers, namely, the acetonitrile [CH3CN]•+ and the …

The incidence of high-energy radiation onto icy surfaces constitutes an important route for
leading new neutral or ionized molecular species back to the gas phase in interstellar and …

In cold core of dark molecular clouds, where the UV radiation from external sources is
strongly attenuated, cosmic rays can induce chemical reactions on the surface of ice …

We report 3 mm continuum, CH 3 CN (5–4) and 13 CS (2–1) line observations with CARMA
(Combined Array for Research in Millimeter-wave Astronomy), in conjunction with 6 and 1.3 …

The Large Latin American Millimeter Array (LLAMA for short) is a joint scientific and
technological undertaking of Argentina and Brazil whose goal is to install and to operate an …

We present results of a survey of methyl cyanide (CH 3 CN) J= 12–11 toward 56 sources,
including 35 Extended Green Objects (EGOs) and 21 nearby AKARI counterparts, with the …
