We present time-series photometry of 31 massive DA white dwarfs with M ≳ 0.9 M ⊙ within the ZZ Ceti instability strip from the Montreal White Dwarf Database 100 pc sample. The majority of the targets had no previous time-series photometry available, though several were classified as nonvariable or potential pulsators in the literature. Out of the

Studying the environments of dusty star-forming galaxies (DSFGs) provides insight into whether these luminous systems are reliable signposts of large-scale overdensities. Evidence suggests that individual DSFGs can trace overdense environments, although this association may not be universal. To test this, we investigate the environments surrounding

This work presents Py2DJPAS, a tool developed in Python to automate the analysis of the properties of spatially resolved galaxies in the miniJPAS survey, a 1 deg 2 survey that acts as precursor of the Javalambre Physics of the Acclerating Universe Survey (J-PAS), using the same filter system and telescope and the J-PAS Pathfinder camera. Our goal

Aims. The polarization of the Ca II resonant doublet (H and K lines) and subordinate infrared triplet lines are valuable observables for diagnosing the magnetism of the solar chromosphere. It is thus necessary to understand in detail the physical mechanisms that play a role in producing their Stokes profiles in the presence of magnetic fields

We present a multiphase, resolved study of the galactic wind extending from the nearby starburst galaxy NGC 4666. For this, we use VLT/MUSE observations from the GECKOS program and H I data from the WALLABY survey. We identify both ionized and H I gas in a biconical structure extending to at least $z\sim$ 8 kpc from the galaxy disc, with increasing

Most long gamma-ray bursts (LGRBs) originate from a rare type of massive stellar explosion. Their afterglows, while rapidly fading, can initially be extremely luminous at optical and near-infrared wavelengths, making them detectable at large cosmological distances. Here we report the detection and observations of GRB 250314A by the SVOM satellite
