Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

The 15 yr pulsar timing data set collected by the North American Nanohertz Observatory for
Gravitational Waves (NANOGrav) shows positive evidence for the presence of a low …

The Python programming language is a high-level, interpreted (as opposed to compiled)
programming language that has become an industry standard across many computational …

The first few 100 Myr at z> 10 mark the last major uncharted epoch in the history of the
universe, where only a single galaxy (GN-z11 at z≈ 11) is currently spectroscopically …

The Astropy Project supports and fosters the development of open-source and openly
developed Python packages that provide commonly needed functionality to the astronomical …

We reduce and analyse the available JWST ERO and ERS NIRCam imaging (SMACS0723,
GLASS, CEERS) in combination with the latest deep ground-based near-infrared imaging in …

Finding and characterizing the first galaxies that illuminated the early universe at cosmic
dawn is pivotal to understand the physical conditions and the processes that led to the …

We present constraints on cosmological parameters from the Pantheon+ analysis of 1701
light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from z= 0.001 to …

We present JADES JWST/NIRSpec spectroscopy of GN-z11, the most luminous candidate
z> 10 Lyman break galaxy in the GOODS-North field with M UV=− 21.5. We derive a redshift …
