Solar-type protostars have been shown to harbor highly deuterated complex organics as for example witnessed by the high relative abundances of doubly and triply deuterated...

We present the detection of [CII] 158um emission from the Spiderweb galaxy at z=2.1612 using the Atacama Pathfinder EXperiment. The line profile splits into an active galactic...

There is a class of binary post-asymptotic giant branch (post-AGB) stars that exhibit remarkable near-infrared excess. Such stars are surrounded by Keplerian or quasi-Keplerian...

Class I protostars are a bridge between Class 0 protostars (<=10^5^yr old), and Class II (>=10^6^yr) protoplanetary disks. Recent studies show gaps and rings in the dust...

In the past few years, there has been a rise in the detection of streamers, asymmetric flows of material directed toward the protostellar disk with material from outside a...

Brightest Cluster Galaxies (BCGs) are typically massive ellipticals at the centers of clusters. They are believed to experience strong environmental processing, and their mass...

Water vapor (H_2_O) is one of the brightest molecular emitters after carbon monoxide (CO) in galaxies with high infrared (IR) luminosity, allowing us to investigate the warm and...

We present the results of millimetre-wave spectroscopic and continuum observations of comet C/2020 F3 (NEOWISE) undertaken with the Institut de RadioAstronomie Millimetrique...

The 1.3deg (G1.3) and 1.6deg (G1.6) cloud complexes in the Central Molecular Zone (CMZ) of our Galaxy have been proposed to possibly reside at the intersection region of the X1...

The total disk gas mass and elemental C, N, and O composition of protoplanetary disks are crucial ingredients for improving our understanding of planetary formation. Measuring...

The BL Lac PKS 1413+135 was observed by the Large Survey Project "MeerKAT Absorption Line Survey" (MALS) in the L-band, at 1139MHz and 1293-1379MHz, targeting the Hi and OH...

Brightest cluster galaxies (BCGs) at the centers of clusters are among the most massive galaxies in the Universe. Their star formation history and stellar mass assembly are...

We present the results of a molecular survey of comet 67P/Churyumov-Gerasimenko undertaken with the Institut de RadioAstronomie Millimetrique (IRAM) 30-m radio telescope in...

Methylamine (CH_3_NH_2_) was first detected in the interstellar medium (ISM) toward Sgr B2 almost 50 years ago by observation of rotational transitions in its torsional ground...

Solar-type prestellar cores and protostars display frequently large amounts of deuterated organic molecules and in particular high relative abundances of doubly and triply...

We investigated the molecular environment of AFGL 2298, an obscured Galactic Luminous blue variable (LBV) star which hosts a highly structured circumstellar environment with...

We determine the ortho/para ratios of NH_2_D and NHD_2_ in two dense, starless cores, where their formation is supposed to be dominated by gas-phase reactions, which, in turn,...

Asymptotic giant branch (AGB) stars are major contributors to the chemical enrichment of the ISM through nucleosynthesis and extensive mass loss. Most of our current knowledge...

Water maser emission is often found in the circumstellar envelopes of evolved stars, that is, asymptotic-giant-branch stars and red supergiants with oxygen-rich chemistry. The...

Episodic accretion in protostars leads to luminosity outbursts that end up heating their surroundings. This rise in temperature pushes the snow lines back, enabling the...
