Isobutene ((CH_3_)2_C=CH_2) is one of the four isomers of butene (C_4_H_8_). After the detection of propene (CH_3_CH=CH_2_) toward TMC-1, and also in the warmer environment of...

The z-GAL survey observed 137 bright Herschel-selected targets with the IRAM Northern Extended Millimeter Array, with the aim to measure their redshift and study their...

We present the dust properties of 125 bright Herschel galaxies selected from the z-GAL NOEMA spectroscopic redshift survey. All the galaxies have precise spectroscopic redshifts...

Using the IRAM NOrthern Extended Millimetre Array (NOEMA), we conducted a Large Programme (z-GAL) to measure redshifts for 126 bright galaxies detected in the Herschel...

The origin of the stellar initial mass function (IMF) and its relation with the core mass function (CMF) are actively debated issues with important implications in astrophysics....

Voids are the most under-dense large-scale regions in the Universe. Galaxies inhabiting voids are one of the keys to understand the intrinsic processes of galaxy evolution, as...

Astronomers have yet to establish whether high-mass protostars form from high-mass prestellar cores, similar to their lower-mass counterparts, or from lower-mass fragments at...

Complex organic molecules (COMs) are commonly detected in and near star-forming regions. However, the dominant process in the release of these COMs from the icy grains -- where...

New-generation spectroscopic surveys of the Milky Way plane have been revealing the structure of the interstellar medium, allowing the simultaneous study of dense structures...

While some galactic bars show recent massive star formation (SF) along them, some others present a lack of it. Whether bars with low level of SF are a consequence of low star...

The Andromeda galaxy is the best known large galaxy besides our own Milky Way. Several images and studies exist at all wavelengths from radio to hard X-ray. Nevertheless, only...

Hyper-compact (HC) or ultra-compact HII regions are the first manifestations of the radiation feedback from a newly born massive star. Therefore, their study is fundamental to...

We present new Atacama Large Millimeter/Submillimeter Array (ALMA) observations of the [CII] 158um transition and the dust continuum in HZ4, a typical star-forming galaxy when...

A key piece of information to understand the origin and role of protoplanetary disk substructures is their dust content. In particular, disk substructures associated with gas...

We used spatially resolved ALMA observations of the three CO isotopologues ^12^CO, ^13^CO and C^18^O (J=2-1) from CQ Tau to analyse the brightness temperature and kinematics of...

We present the first cluster catalogue extracted from combined space- (Planck) and ground-based (South Pole Telescope; SPT-SZ) millimeter data. We develop and apply a Matched...

Planetary cores are thought to form in proto-planetary disks via the growth of dusty solid material. However, it is unclear how early this process begins. We study the physical...

The mass segregation of stellar clusters could be primordial rather than dynamical. Despite the abundance of studies of mass segregation for stellar clusters, those for stellar...

The complex of star-forming regions in Perseus is one of the most studied due to its proximity (about 300pc). In addition, its regions show variation in star-formation activity...

The dust-to-stellar mass ratio (M_dust_/M) is a crucial yet poorly constrained quantity to understand the complex physical processes involved in the production of dust, metals...
