Using the Institut de Radioastronomie Millmetrique 30m telescope, we presented observations of N_2_H^+^J=1-0, CCS J_N_=8_7_-7_6_ and 7_7_-6_6_ lines toward a large sample of...

The spatial analysis of young stellar objects (YSOs) has proven very valuable to describe and analyse star-forming regions and to understand the star formation process. This...

We present the star formation histories (SFHs) of early-type dwarf galaxies, dSphs and dEs, in the local Universe within z = 0.01. The SFHs of early-type dwarf galaxies are...

We present 500 and 700au resolution 1 and 3mm Atacama Large Millimeter/submillimeter Array observations, respectively, of protostellar cores in protoclusters Sagittarius B2 (Sgr...

We present the clump populations detected in 18 lensed galaxies at redshifts 1-- 8.5 within the lensing cluster field SMACS0723. The recent JWST Early Release Observations of...

We present an analysis of the young stellar moving group ASCC 127 using Gaia DR3 data, significantly expanding its membership to 3971 stars-double the number identified in...

Several studies have reported a nearly linear correlation between the molecular gas and star formation rate surface density, the so-called Kennicutt-Schmidt (KS) law. We aim to...

High-mass prestellar cores are extremely rare. Until recently, the search for such objects has been hampered by small sample sizes, leading to large ambiguities in their...

The ALMA-IMF Large Program imaged 15 massive protoclusters down to a resolution of 2kau scales, identifying about 1000 star-forming cores. The mass and luminosity of these...

Substructures such as rings, gaps, and cavities are commonly observed in protoplanetary discs and are thought to play a key role in dust evolution and planet formation. However,...

I present infrared spectroscopy of 37 brown dwarf candidates in the Upper Scorpius (Upper Sco) association, 35 of which are classified as young and cool, making them likely...

We present high-resolution rotation curves and mass models of 26 dwarf galaxies from "Local Irregulars That Trace Luminosity Extremes, The H_I_ Nearby Galaxy Survey" (LITTLE...

Radial colour gradients within galaxies arise from gradients of stellar age, metallicity, and dust reddening. Large samples of colour gradients from wide- area imaging surveys...

We analyse the spatial statistics of the 2D gas-phase oxygen abundance distributions in a sample of 219 local galaxies. We introduce a new adaptive binning technique to enhance...

We present size measurements of 78 high-redshift (z => 5.5) galaxy candidates from the Reionization Lensing Cluster Survey (RELICS). These distant galaxies are well resolved...

We investigate the stellar populations and molecular gas properties of a star- forming region within the dwarf irregular (dIrr) galaxy Wolf-Lundmark-Mellote (WLM)....

We report the spatial distribution and physical characteristics of molecular clouds in the G24 region, which is located near the intersection of the Milky Way's Galactic bar...

Stars form in cold molecular clouds. However, molecular gas is difficult to observe because the most abundant molecule (H_2_) lacks a permanent dipole moment. Rotational...

We have studied the environment of the FU Ori type star V582 Aur. Our aim is to explore the star-forming region associated with this young eruptive star. Using slitless...

We present the first study of GALEX far-ultraviolet (FUV) luminosity functions of individual star-forming regions within a sample of 258 nearby galaxies spanning a large range...
