EPIC 204376071 is a young ($\sim$10 Myr) M star (estimated mass 0.16 M$_\odot$, and radius 0.63 R$_\odot$), probable member of the Upper Sco association, that exhibited an 80% drop in flux lasting one day, in the course of one campaign of the K2 mission (Rappaport et al. 2019). Different scenarios have been proposed to explain this feature, some of

Scientific complementary metal-oxide-semiconductor (CMOS) detectors have developed quickly in recent years thanks to their low cost and high availability. They also have some advantages over charge-coupled devices (CCDs), such as high frame rate or typically lower readout noise. These sensors started to be used in astronomy following the

Recent cosmological analyses rely on the ability to accurately sample from high-dimensional posterior distributions. A variety of algorithms have been applied in the field, but justification of the particular sampler choice and settings is often lacking. Here, we investigate three such samplers to motivate and validate the algorithm and settings

Asteroseismology is playing an increasingly important role in the characterization of red giant host stars and their planetary systems. Here, we conduct detailed asteroseismic modeling of the evolved red giant branch (RGB) hosts KOI-3886 and ι Draconis, making use of end-of-mission Kepler (KOI-3886) and multisector TESS (ι Draconis) time-series

Active galactic nuclei (AGNs) play a crucial role in galaxy evolution, as their feedback has been proposed to shape some galaxy properties (for instance, the galaxy luminosity functions). Ionised outflows and their feedback effects have been routinely studied in powerful AGNs, but are less explored for Seyfert galaxies. The abundance of the latter

Blazars are a subclass of active galactic nuclei (AGNs) with a relativistically boosted jet pointing towards the Earth. They are one of the most violent and variable objects in the Universe, showing extreme variability across the entire electromagnetic spectrum. The jet generally dominates the optical emission of these sources. However, other
