This catalogue, developed for a new study of the interstellar medium in the solar vicinity, contains estimations of extinction and distances from reliable UBV data and MK types;...

We use 101 galaxies selected from the Nearby Field Galaxy Survey to investigate the effect of aperture size on the star formation rate, metallicity, and reddening determinations...

Understanding the characteristics of young stellar populations is essential for deriving insights into star formation processes within parent molecular clouds and the influence...

We present new luminosity-metallicity (LZ ; M_V_-[Fe/H] and M_G_-[Fe/H]) and relations and, for the first time, empirical, Gaia three-band (G, G_BP_, G_RP_)...

We study in detail the properties of the stellar populations of 111 massive [log(M/M_{sun}_) => 10] dusty [far-infrared (FIR)-selected] starburst (SFR/SFRMS > 2) galaxies...

We present the space density evolution, from z = 1.5 up to z = 5.5, of the most massive (M => 10^9^ M_{sun}) black holes hosted in jetted active galactic nuclei (AGNs). The...

We present a catalogue of 16551 edge-on galaxies created using the public DR2 data of the Pan-STARRS survey. The catalogue covers the three quarters of the sky above Dec. =...

We present a large catalogue of molecular clouds with accurate distance estimates in the Southern sky. Based on the three-dimensional dust extinction map and the best-fitting...

In this work, we study the optical properties of compact radio sources selected from the literature in order to determine the impact of the radio-jet in their circumnuclear...

We present a one-dimensional, local thermodynamic equilibrium homogeneous analysis of 132 stars observed at high resolution with ESPaDOnS. This represents the largest sample...

Photoelectric magnitudes and color indices in the Vilnius seven-color system for 152 stars are used to investigate the interstellar extinction in the area of the Aries molecular...

We identify 709 arc-shaped mid-infrared nebula in 24um Spitzer Space Telescope or 22um Wide Field Infrared Explorer surveys of the Galactic Plane as probable dusty interstellar...

Deep rest-frame optical spectroscopy is critical for characterizing and understanding the physical conditions and properties of the ionized gas in galaxies. Here, we present a...

We present measurements of the Hubble diagram for 103 Type Ia supernovae (SNe) with redshifts 0.04<z<0.42, discovered during the first season (Fall 2005) of the Sloan...

We present our analysis of the Lyman continuum (LyC) emission and escape fraction of 111 spectroscopically verified galaxies with and without active galactic nuclei (AGN) from...

In order to obtain a complete census of the stellar and substellar population, down to a few M_Jup_ in the ~1Myr old Orion Nebula Cluster, we used the infrared channel of the...

The sight line toward the luminous blue hypergiant CygOB2-12 is widely used to study interstellar dust on account of its large extinction (AV~10mag) and the fact that this...

We present new near-infrared spectroscopic observations of the outer edges of the young stellar cluster around the supermassive black hole at the Galactic center. The...

We test state-of-the-art model atmospheres for young very-low-mass stars and brown dwarfs in the infrared, by comparing the predicted synthetic photometry over 1.2-24{mu}m to...

The production rate of ionizing photons in young (<=8Myr), unresolved stellar clusters in the nearby irregular galaxy NGC 4214 is probed using multi-wavelength Hubble Space...
