We present, for the first time, model spectra of single-age, single-metallicity stellar populations computed with the E-MILES evolutionary synthesis code incorporating an environment-dependent, variable galaxy-wide initial mass function (gwIMF). This gwIMF, calculated using the GalIMF code, is rooted in the integrated galactic initial mass function

We investigated the star formation activity and black hole scaling relations in a sample of 1 451 active galactic nuclei (AGNs) hosted by dwarf galaxies (log(M ⋆/M ⊙) < 10) at 0.5 < z < 0.9, drawn from the VIPERS survey. The sample comprises Seyferts and low-ionization nuclear emission-line regions (LINERs) identified through emission-line

Asteroseismology of solar-like oscillators has undergone a remarkable transformation over the past decade, propelled by high-precision photometric data from Kepler, K2, and TESS, alongside significant advances in stellar modeling. These developments have enabled detailed investigations of stellar interiors across a broad range of evolutionary

Aims. We investigated binary-lens events from the 2022–2024 microlensing surveys, aiming to identify events suitable for lens mass measurements. We focused on two key light curve features: distinct caustic spikes with resolved crossings for measuring the angular Einstein radius (θ E), and long durations enabling microlens-parallax (π E)

Binary stars are essential astrophysical test-beds. As the components of binary systems are formed from the same material and at the same time, they share fundamental properties such as their age and initial composition. Among the different types of binary systems, eclipsing binaries give the most stringent constraints about the stars, such as the

The modern synthetic tracking technique (ST) can make use of small and medium-sized telescopes to detect asteroids fainter than the classic blinking methods, by arbitrary shifting and co-adding more images of the same survey field, if GPU computing resources are available. In the framework of the Romanian ParaSOL project, we developed and tested an
