Context. Understanding the formation, evolution and present-day properties of the cosmic web and objects forming it is an important task in cosmology. Aims: We...
Search and analysis of giant radio galaxies with associated nuclei (SAGAN). IV. Interplay with the Supercluster environment
We investigated the prevalence of giant radio galaxies (GRGs), some of the largest structures powered by supermassive black holes, within supercluster...
Search and characterization of T-type planetary mass candidates in the σ Orionis cluster
Context. The proper characterization of the least massive population of the young σ Orionis star cluster is required to understand the form of the cluster mass...
Search for an extended VHE γ-ray emission from Mrk 421 and Mrk 501 with the MAGIC Telescope
Context. Part of the very high energy γ-ray radiation coming from extragalactic sources is absorbed through the pair production process on the extragalactic...
Search for flares and associated CMEs on late-type main-sequence stars in optical SDSS spectra
Aims: This work aims to detect and classify stellar flares and potential stellar coronal mass ejection (CME) signatures in optical spectra provided by the Sloan...
Search for forced oscillations in binaries. III. Improved elements and the detection of line-profile variability of the B4V + A6V: system AR Cassiopeiae
An analysis of a new and extensive set of spectroscopic observations of the early-type binary system {AR Cas} , based also on spectral disentangling, has led to...
Search for free-floating planetary-mass objects in the Pleiades
Aims: We aim at identifying the least massive population of the solar metallicity, young (120 Myr), nearby (133.5 pc) Pleiades star cluster with the ultimate...
Search for Galactic runaway stars using Gaia Data Release 1 and HIPPARCOS proper motions
Context. The first Gaia Data Release (DR1) significantly improved the previously available proper motions for the majority of the Tycho-2 stars. Aims: We wish...
