We have used the Shanghai Tianma Radio Telescope to search for three OH transitions at 4.7GHz toward 155 northern star formation regions. We detect 4.7GHz OH masers in 18 star...

We investigate the influences on the evolution of the Fundamental Metallicity Relation of different selection criteria. We used 5487 star-forming galaxies at a median redshift...

The 30 Doradus star-forming region in the Large Magellanic Cloud is a nearby analog of large star-formation events in the distant universe. We determined the recent formation...

Ultra-compact H II (UC HII) regions are an important phase in the formation and early evolution of massive stars and a key component of the interstellar medium (ISM). The main...

A total of 197 relatively isolated high-mass star-forming clumps were selected from the Millimeter Astronomy Legacy Team 90GHz (MALT90) survey data and their global chemical...

ATLASGAL is an 870um dust survey of 420deg^2^ the inner Galactic plane and has been used to identify ~10000 dense molecular clumps. Dedicated follow-up observations and...

We present the global scaling relations between the neutral atomic hydrogen gas, the stellar disc, and the star-forming disc in a sample of 228 nearby galaxies that are both...

We have used ALMA and NOEMA to study the molecular gas reservoirs in 61 ALMA-identified submillimetre galaxies (SMGs) in the COSMOS, UDS, and ECDFS fields. We detect ^12^CO...

Deuterated methanol is one of the most robust windows astrochemists have on the individual chemical reactions forming deuterium-bearing molecules and the physicochemical history...

The Herschel Gould Belt survey mapped the nearby (d<500pc) star-forming regions to understand better how the prestellar phase influences the star formation process. Here, we...

The processes that regulate star formation within molecular clouds are still not well understood. Various star formation scaling relations have been proposed as an explanation,...

The nearby Hydra cluster (~50Mpc) is an ideal laboratory to understand, in detail, the influence of the environment on the morphology and quenching of galaxies in dense...

A relationship between dust-reprocessed light from recent star formation and the amount of star-forming gas in a galaxy produces a correlation between Wide-field Infrared Survey...

In order to search for shocks in the very early stage of star formation, we performed single-point surveys of SiO J=1-0, 2-1, and 3-2 lines and the H_2_CO 2_12_-1_11_ line...

We present a study of the metal-enriched cool halo gas traced by MgII absorption around 228 galaxies at z~0.8-1.5 within 28 quasar fields from the MUSE Analysis of Gas around...

We explore the effects of tidal interactions on star formation (SF) by analysing a sample of CALIFA survey galaxies. The sample consists of tidally and non-tidally perturbed...

We analyse two-dimensional maps and radial profiles of EW(H{alpha}), EW(H{delta}A), and D_n_(4000) of low-redshift galaxies using integral field spectroscopy from the MaNGA...

Our Milky Way provides a unique test case for galaxy evolution models because of our privileged position within the Milky Way's disc. This position also complicates comparisons...

Supernovae (SNe) dominate the energy and momentum budget of stellar feedback, but the efficiency with which they couple to the interstellar medium (ISM) depends strongly on how...

The current generation of (sub)mm-telescopes have allowed molecular line emission to become a major tool for studying the physical, kinematic, and chemical properties of...
