Context. Extremely metal-poor (XMP) galaxies are chemically, and possibly dynamically, primordial objects in the local Universe. Aims: Our objective is to...
Extremely metal-poor stars in classical dwarf spheroidal galaxies: Fornax, Sculptor, and Sextans
We present the results of a dedicated search for extremely metal-poor stars in the Fornax, Sculptor, and Sextans dSphs. Five stars were selected from two...
Eyes on K2-3: A system of three likely sub-Neptunes characterized with HARPS-N and HARPS
Context. M-dwarf stars are promising targets for identifying and characterizing potentially habitable planets. K2-3 is a nearby (45 pc), early-type M dwarf...
Fabry-Perot observations of the ionized gas in NGC 3938
The nearly face-on spiral galaxy NGC 3938 has been observed in the H_alpha line with the TAURUS II Fabry-Perot interferometer at the William Herschel Telescope...
Fabry-Perot observations of the ionized gas in the spiral galaxy NGC 6951
We present two dimensional kinematic observations at high angular and velocity resolution measured via the Hα emission line in the active barred spiral NGC 6951...
Faint recombination lines in Galactic PNe with a [WC] nucleus
Aims: We present spatially resolved high-resolution spectrophotometric data for the planetary nebulae PB 8, NGC 2867, and PB 6. We have analyzed two knots in...
Far-infrared constraints on the contamination by dust-obscured galaxies of high-z dropout searches
The spectral energy distributions (SED) of dusty galaxies at intermediate redshift may look similar to very high-redshift galaxies in the optical/near infrared...
Far-infrared properties of submillimeter and optically faint radio galaxies
We use deep observations obtained with the Photodetector Array Camera and Spectrometer (PACS) onboard the Herschel Space Observatory to study the far-infrared...
