Although over 30 such quasars are now known at $z > 5. 5$, the signal remains elusive in practice, owing to instrumental noise, the intrinsic weakness of the absorption features, and the limited brightness of available background sources.

An accurate measurement of the spectral resolution of the JWST Near Infrared Spectrograph
In this letter, we present a robust measurement of the spectral resolution for the JWST's Near Infrared Spectrograph (NIRSpec) in all its modes: fixed slit (FS), integral field spectroscopy (IFS), and multi-object spectroscopy (MOS).

Volatile-rich evolution of molten super-Earth L 98-59 d
Small low-density exoplanets are sculpted by strong stellar irradiation but their origin is unknown.

We find that this scenario can match a large number of constraints, including i) the terrestrial planets' masses and orbits; ii) the CC mass fraction of Earth; iii) the much lower CC mass fraction of Mars, as long as Mars only accreted CC planetesimals (but no CC embryos); iv) the timing of the last giant (Moon-forming) impact; and v) a late accretion phase dominated by non-carbonaceous (NC) bodies.

Detectability and Parameter Estimation for Einstein Telescope Configurations with GWJulia
Future gravitational-wave (GW) detectors are expected to detect tens of thousands of compact binary coalescences (CBC) per year, depending also on the final detectors layout.

Physics Of Eclipsing Binaries. VII. Interferometric module
Interferometric measurements are essential to constrain models of stellar systems, by spatially resolving angular distances and diameters well below the classical diffraction limit.

Physics Of Eclipsing Binaries. VIII. Multiple systems
In this work, we describe the new dynamical model in Phoebe, which could be used just for this purpose.

Physics Of Eclipsing Binaries. IX. Spectroscopic module
Spectroscopic observations constrain the fundamental properties of stellar atmospheres, in particular, the effective temperature, the gravitational acceleration, or the metallicity.

Predicting wide binaries and deviations from standard gravity using machine learning algorithms
We present a machine learning (ML) framework for the detection of wide binary star systems and the identification of deviations from standard gravity using Gaia DR3 data.
