Previous work detected transient ultraviolet outflow features for the short-period (P $_{\mathrm{orb}}{\approx }111$ min), low-mass X-ray binary (LMXB) UW CrB, suggesting the presence of a disc wind in the system. However, because of the transient nature of the outflow features, and the limited amount of data available, the features were

Context. Beta Pictoris is an A-type star that hosts a complex planetary system with two massive gas giants and a prominent debris disc. Variable absorption lines in its stellar spectrum have been interpreted as signatures of exocomets ─ comet-like bodies transiting the star. Stellar flybys can gravitationally perturb objects in the outer comet

In recent years, imaging atmospheric Cherenkov telescopes (IACTs) have emerged as promising platforms for optical interferometry through the use of intensity interferometry. IACTs combine large segmented mirrors, photodetectors with nanosecond-scale time response capable of detecting signals from just a few photo-electrons, and array configurations

En este trabajo se reinterpreta el heroon de El Pajarillo, en el marco del mito de la katabasis o viaje del héroe al inframundo. Para esta lectura se han realizado estudios arqueoastronómicos y se ha integrado el heroon en un camino de pagus, que sigue las aguas del río Jandulilla. En este nuevo territorio se ha añadido un nuevo hito arqueológico

We combine near-infrared imaging in two bands from the Hubble Space Telescope with archival observations of molecular gas to study SDSS J160705.16+533558.6 (J1607), an extremely luminous broad-line quasar at z = 3.65 that is also bright in the submillimeter. Via subtraction of the quasar point-spread function, we show that its host galaxy is

Cherenkov Telescope Array Observatory (CTAO) is the next-generation ground-based $\gamma$-ray observatory operating in the energy range from $20\, \mathrm{GeV}$ up to $300\, \mathrm{TeV}$, with two sites in La Palma (Spain) and Paranal (Chile). It will consist of telescopes of three sizes, covering different parts of the large energy range. We
