Long-period radio transients (LPTs) are periodic radio sources showing pulsed emission on time-scales from minutes to hours. The underlying sources behind this emission are currently unclear. There are two leading candidates: neutron stars or white dwarfs. Neutron stars could emit at LPT time-scales as magnetars, binaries, or precessing sources

Increasing space activities, especially in low-Earth orbits (LEO), lead to more orbital debris and night-sky pollution. Spectroscopic analysis of light reflected from artificial space objects can aid to identify dominant surface materials and their reflective properties. Satellites interact with sunlight in diffuse and specular reflections, which

Hot Jupiters and their atmospheres are prime targets for transmission spectroscopy due to their extended atmospheres and the corresponding large signal-to-noise, providing the best possible constraints for the atmospheric carbon-to-oxygen (C/O) ratio and metallicity of exoplanets. Within BOWIE-ALIGN, we aim to compare JWST spectra of a sample of

Planetary radii are derived for 218 exoplanets orbiting 161 M dwarf stars. Stellar radii are based on an analysis of APOGEE high-resolution near-IR spectra for a subsample of the M dwarfs; these results are used to define a stellar radius-M K s calibration that is applied to the sample of M-dwarf planet hosts. The planetary radius distribution

Radio pulsating white dwarf (WD) systems, known as WD pulsars, are binary systems where the rapidly spinning WD interacts with a low-mass companion, producing pulsed non-thermal emission observed across the entire electromagnetic spectrum. Only two such systems are known: AR Sco and eRASSU J191213.9–441044. Here, we present the discovery of a third

To understand how massive galaxies are influenced by their surroundings, we present new Atacama Large Millimeter/submillimeter Array and Northern Extended Millimeter Array observations as part of A Multiwavelength Study of Enormous Lyα Nebula (ELAN) Environments (AMUSE 2). These observations target submillimeter sources discovered in single-dish
