Measuring the brightness of the night sky has become an increasingly important topic in
recent years, as artificial lights and their scattering by the Earth's atmosphere continue …

The final phase of the reionization process can be probed by rest-frame UV absorption
spectra of quasars at z≳ 6, shedding light on the properties of the diffuse intergalactic …

The atmospheres of gaseous giant exoplanets orbiting close to their parent stars (hot
Jupiters) have been probed for nearly two decades,. They allow us to investigate the …

The merger of two neutron stars is predicted to give rise to three major detectable
phenomena: a short burst of γ-rays, a gravitational-wave signal, and a transient optical–near …

The Multi-Core Integral-Field Unit (MCIFU) is a new diffraction-limited near-infrared integral-
field unit for exoplanet atmosphere characterization with extreme adaptive optics (xAO) …

Context. The interaction of the light from astronomical objects with the constituents of the
Earth's atmosphere leads to the formation of telluric absorption lines in ground-based …

High-resolution spectroscopy (R≥ 25,000) has recently emerged as one of the leading
methods for detecting atomic and molecular species in the atmospheres of exoplanets …

The mean free path of ionizing photons, λ mfp, is a critical parameter for modeling the
intergalactic medium (IGM) both during and after reionization. We present direct …

ABSTRACT The Southern Photometric Local Universe Survey (S-PLUS) is imaging∼ 9300
deg2 of the celestial sphere in 12 optical bands using a dedicated 0.8 m robotic telescope …

Context. Absorption by molecules in the Earth's atmosphere strongly affects ground-based
astronomical observations. The resulting absorption line strength and shape depend on the …
