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...

This work presents the properties of 42 objects in the group of the most luminous, highest star formation rate (SFR) low-ionization nuclear emission-line regions (LINERs) at...

We carried out a spectral line survey of CH3OH toward a large sample of 175 high-mass star-forming regions in the 3mm, 2mm, and 1.3mm bands with the Institut de Radioastronomie...

We have conducted a line survey toward Orion KL using the Q-band receiver of the Tianma 65m radio telescope (TMRT), covering 34.8-50GHz with a velocity resolution between 0.79...

As part of the Bar and Spiral Structure Legacy (BeSSeL) Survey, we have used the Very Long Baseline Array (VLBA) to measure 16 trigonometric parallaxes and proper motions of...

A four-epoch monitoring program spanning ~three months (from 2020-January-8 to April-7) for ammonia, water, and methanol transitions toward the high-mass star-forming region W51...
