Deep learning with artificial neural networks is increasingly gaining attention because of its
potential for data-driven astronomy. However, this methodology usually does not provide …

We demonstrate a novel technology that combines the power of the multi-object
spectrograph with the spatial multiplex advantage of an integral field spectrograph (IFS). The …

Wide-field optical surveys have begun to uncover large samples of fast (t rise≲ 5 d),
luminous (M peak<− 18), blue transients. While commonly attributed to the breakout of a …

Precise measurements of chemical abundances in planetary atmospheres are necessary to
constrain the formation histories of exoplanets. A recent study of WASP-127 b, a close-in …

ABSTRACT VANDELS is a uniquely deep spectroscopic survey of high-redshift galaxies
with the VIMOS spectrograph on ESO's Very Large Telescope (VLT). The survey has …

Astrophysicists are increasingly taking into account the effects of orbiting companions on
stellar evolution. New discoveries have underlined the role of binary star interactions in a …

Ground-based high-resolution transmission spectroscopy has emerged as a promising
technique for detecting chemicals in transiting exoplanetary atmospheres. Despite chemical …

The CRyogenic InfraRed Echelle Spectrograph (CRIRES) Upgrade project CRIRES+
extended the capabilities of CRIRES. It transformed this VLT instrument into a cross …

The measurement of the structure of stellar populations in the Milky Way disc places
fundamental constraints on models of galaxy formation and evolution. Previously, the disc's …

We present a study of the metal-enriched halo gas, traced using Mg ii and [O ii] emission
lines, in two large, blind galaxy surveys–the MUSE (Multi Unit Spectroscopic Explorer) …
