Identifying the young optically visible population in a star-forming region is essential for fully understanding the star formation event. In this paper, we identify 211...

The star-forming region W5 is a major part of the Cassiopeia OB6 association. Its internal structure and kinematics may provide hints of the star formation process in this...

We have conducted a study of star formation in the outer Galaxy from 65{deg}<l<265{deg} in the region observed by the GLIMPSE360 program. This Spitzer warm mission program...

For the first time, the helium abundance relative to hydrogen (He/H), which relied on direct measurements of the electron temperature, has been derived in the narrow line...

Superthin galaxies (STs) are edge-on disc galaxies with strikingly high planar-to-vertical axes ratios of ~10-20 with no bulge component, and central surface brightness in the B...

The importance of the post-merger epoch in galaxy evolution has been well documented, but post-mergers are notoriously difficult to identify. While the features induced by...

We infer the intrinsic ionized gas kinematics for 383 star-forming galaxies across a range of integrated star formation rates (SFR{in}[10^-3^, 10^2^]M_{sun}/yr) at z~<0.1...

The attenuation of light from star-forming galaxies is correlated with a multitude of physical parameters including star formation rate, metallicity and total dust content. This...

Star formation activity depends on galactic-scale environments. To understand the variations in star formation activity, comparing the properties of giant molecular clouds...

Outflows form an integral component in regulating the gas cycling in and out of galaxies, although their impact on the galaxy hosts is still poorly understood. Here we present...

We combine new CO(1-0) line observations of 24 intermediate redshift galaxies (0.03<z<0.28) along with literature data of galaxies at 0<z<4 to explore scaling...

Identifying and characterizing young populations of star-forming regions are crucial to unraveling their properties. In this regard, Gaia-DR3 data and machine-learning tools are...

In spite of much work, the overall spiral structure morphology of the Milky Way remains somewhat uncertain. In the last two decades, accurate distance measurements have provided...

We measure empirical relationships between the local star formation rate (SFR) and properties of the star-forming molecular gas on 1.5kpc scales across 80 nearby galaxies. These...

In this work, we present 299 candidate young stellar objects (YSOs) in 30 Doradus discovered using Spitzer and Herschel point-source catalogs, 276 of which are new. We study the...

High-mass stars play an important role in the interstellar medium, but much remains to be known about their formation. Class I methanol masers may be unique tracers of an early...

We analyze the internal dynamics of young stars toward Perseus using Gaia EDR3 data, including PerOB2 and California Cloud. Interpreting the current dynamics, we speculate that...

The Andromeda galaxy (M31) is an object of ongoing study with the Ultraviolet Imaging Telescope (UVIT) on AstroSat. UVIT far-UV (FUV) and near-UV (NUV) photometry is carried out...

We present the most complete to date interferometric study of the centimeter-wavelength methanol masers detected in G358.93-0.03 at the burst and post-burst epochs. A unique,...

We have performed a census of the young stellar populations near the Corona Australis molecular cloud using photometric and kinematic data from several sources, particularly...
