The two-colour EMCCD instrument for the Danish 1.54 m telescope and SONG
We report on the implemented design of a two-colour instrument based on electron-multiplying CCD (EMCCD) detectors. This instrument is currently installed at...
The ultraluminous X-ray source NGC 1313 X-2. Its optical counterpart and environment
NGC 1313 X-2 is one of the brightest ultraluminous X-ray sources in the sky, at both X-ray and optical wavelengths; therefore, quite a few studies of available...
The uncertain interstellar medium of high-redshift quiescent galaxies: Impact of methodology
How much gas and dust is contained in high-redshift quiescent galaxies (QGs) is currently an open question with relatively few and contradictory answers, as...
The universal variability of the stellar initial mass function probed by the TIMER survey
The debate about the universality of the stellar initial mass function (IMF) revolves around two competing lines of evidence. While measurements in the Milky...
The updated BOSZ synthetic stellar spectral library
Context. The modeling of stellar spectra of flux standards observed by the Hubble and James Webb space telescopes requires a large synthetic spectral library...
Aims:We introduce analytical response functions and their main properties as an important diagnostic tool that help understand Stokes profile formation physics...
The V-band luminosity function of galaxies in A2151
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 V-R Diagram - a Diagnostic Tool for the Dynamical Classification of Spiral Galaxies
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...
