Over 300 molecules have been identified in the interstellar medium (ISM), including complex species considered precursors to prebiotic chemistry. A remarkable level of molecular diversity has been observed from the earliest stages of star formation, providing the initial chemical inventory inherited by planetary systems.
(Sub-)millimeter observations have revealed complex organic molecules...

Jets and molecular outflows are ubiquitous phenomena associated with the formation of young stellar objects (YSOs). They play a crucial role in removing angular momentum from the accreting system and in regulating star-formation efficiency. Theoretical studies and observations with ALMA and VLA have shown that jets and winds may have a crucial role in promoting dust growth in the envelope-disc...

In recent years, ALMA has revealed an astonishing variety of disk structures, though the precise relationship between these morphologies and planet formation remains elusive. A major challenge with ALMA is its limited sensitivity to larger dust grains (those approaching centimeter scales) which are crucial for understanding early stages of planet formation. Moreover, the common occurrence of...

The ordered magnetospheres of chemically peculiar (CP) massive stars and ultracool dwarfs (UCDs) provide ideal environments for non-thermal particle acceleration. In CP stars, radiatively driven winds are trapped into rigidly rotating magnetospheres until centrifugal breakout (CBO) occurs, when centrifugal forces overwhelm magnetic tension. These breakout events trigger reconnection and inject...

The strong shocks involved in supernova remnants (SNRs) and their interaction with an often anisotropic surrounding medium make them very complex objects and ideal laboratories to study the production and acceleration of Galactic cosmic rays (CRs).

Circumstellar shells are a key manifestation of the mass-loss processes of evolved stars in the radio band. These faint and compact ring-like structures---from planetary nebulae around low- and intermediate-mass stars to the ejecta surrounding the more massive Luminous Blue Variables and Wolf-Rayets---are the result of the interplay between stellar winds and eruptions and the surrounding ISM....

Magnetic fields in starless, prestellar cores are crucial for understanding the formation of stars, as these cores mark the initial gravitationally bound stage in the star-formation process. Typically, these cores accumulate gas from their molecular cloud environments until they overcome magneto-turbulent support and collapse into protostellar objects. Traditional studies of magnetic fields in...

Maser emission is an multi-purpose tool of astrophysical research, offering a unique window into a vast range of astronomical sources and spatial scales - from a few astronomical units around forming protostars to kiloparsecs in distant galaxies. These naturally occurring microwave amplifiers penetrate the dust shells of star-forming regions, unveiling the intricate dynamics of accretion disks...

Our Milky Way is a unique laboratory to investigate the (massive) star formation mechanisms with a detail that cannot be reached in any other galaxy. These multi-scale processes are regulated by a complex interplay between gravity, turbulence and feedback which vary from region to region. Large surveys of the Galactic Plane (GP) have been proved as a particularly powerful tool to investigate...

To date, the Galactic interstellar radial $^{32}$S/$^{34}$S gradient has only been studied with the CS isotopologs, which may be affected by uncertainties due to the use of a single tracer. As another abundant S-bearing molecules, SO and its isotopomer $^{34}$SO could be considered as tracers of the $^{32}$S/$^{34}$S ratio. We present the first systematic observations of SO and $^{34}$SO...
