Context. The modeling of stellar spectra of flux standards observed by the Hubble and James Webb space telescopes requires a large synthetic spectral library...

The MAGIC Cherenkov telescopes underwent a major upgrade in 2011 and 2012. A new 1039-pixel camera and a larger area digital trigger system were installed in...

In a previous work (Paper I of this series), we presented a procedure for computing the temperature distribution in a stellar atmosphere under the constraint of...

We demonstrate that near-infrared CVF spectrometry can be used to determine accurately the spectral type and luminosity class of K- and M-type stars. As an...

Aims:We introduce analytical response functions and their main properties as an important diagnostic tool that help understand Stokes profile formation physics...

We report the discovery of J0121+0025, an extremely luminous and young star-forming galaxy (M UV = -24.11, log[$L_{\rm Ly \alpha } / \rm erg~s^{-1}] = 43.8$) at...

The UV-Excess survey of the northern Galactic plane images a 10° × 185° wide band, centred on the Galactic equator using the 2.5-m Isaac Newton Telescope in...

We present a wide field V-band imaging survey of approximately 1 deg2 (~7.2~h-275 Mpc2) in the direction of the nearby cluster of galaxies Abell 2151 (the...

The relations between the angular momentum (J) and the mass (M) for a sample of spiral galaxies are discussed for galaxies distributed in the rotational...
