We investigated three fan-shaped jets observed above sunspot light bridges or nearby sunspot regions. The study aimed to explore the dynamics and physical properties of jets' features that appear as blob-like structures at the tips of the jets, which we call 'dark blobs'. A transparent region is observed beneath the dark blobs, creating a visible

Context. The inference of the magnetic field vector from spectropolarimetric observations is crucial for understanding the physical processes governing the solar corona. Aims. We investigated what information on the magnetic fields of coronal bright points (CBPs) can be gained from the intensity and polarization of the Fe XIII 10747 Å, Fe XIV 5303

Context. In the near-infrared (NIR) region, a large number of absorption features may be used to constrain the properties of unresolved stellar populations of galaxies. Aims. We present the results of a pilot project assessing the feasibility of measuring the distribution and radial trends of NIR line-strength indices on spatially resolved spectra

Context. Galaxy clusters selected based on overdensities of galaxies in photometric surveys provide the largest cluster samples. However, modeling the selection function of such samples is complicated by noncluster members projected along the line of sight (projection effects) and the potential detection of unvirialized objects (contamination)

Understanding the properties, formation, and evolutionary path of high- mass star systems is a fundamental research topic in stellar astrophysics. Under certain conditions, massive binaries form gravitationally bound compact objects capable of merging in less than the age of the Universe, producing gravitational waves detectable by observatories

In this roadmap article, we consider the main challenges and recent breakthroughs in understanding the role of carbon molecular nanostructures in space and propose future avenues of research. The focus lies on small carbon-containing molecules up to fullerenes, extending to even larger, more complex organic species. The roadmap contains forty
