Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, , , , | Summary: Observations of the cosmic microwave backgroundradiation are described to remarkable accuracy by the six-parameterLambda CDM cosmology. However, the key ingredients of this model, namely dark matter, dark energy and cosmic inflation are not understood at a fundamental level. It is […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Nimisha Kumari, Renske Smit, Joris Witstok, Marco Sirianni, Roberto Maiolino | Summary: We investigate the physical properties of Lyman-alpha emitters (LAEs) and non-Lyman-alpha emitters (non-LAEs) at z$sim$4.8–9.6 via a stacking analysis of 253 JWST/NIRSpec spectra of galaxies observed as part of the JWST Advanced Deep Extragalactic Survey […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Isabella Lamperti, Santiago Arribas, Michele Perna, Bruno Rodríguez Del Pino, Chiara Circosta | Summary: We present JWST NIRSpec observations in IFS mode of the galaxy GS5001 at redshift z=3.47, the brightest member of a candidate protocluster in the GOODS-S field. The data cover a field of view […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Christa DeCoursey, Eiichi Egami, Justin D. R. Pierel, Fengwu Sun, Armin Rest | Summary: The JWST Advanced Deep Extragalactic Survey (JADES) is a multi-cycle JWST program that has taken among the deepest near-infrared images to date (down to $sim$30.5 ABmag) over $sim$25 arcmin$^2$ in the GOODS-S field […]

Pierel, Fengwu Sun, Armin Rest | Summary: The JWST Advanced Deep Extragalactic Survey (JADES) is a multi-cycle JWST program that has taken among the deepest near-/mid-infrared images to date (down to $sim$30 ABmag) over $sim$25 arcmin$^2$ in the GOODS-S field […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Tamara Evstafyeva, Ulrich Sperhake, Isobel Romero-Shaw, Michalis Agathos, | Summary: Gravitational-wave signals detected to date are commonly interpreted under the paradigm that they originate from pairs of black holes or neutron stars. Here, we explore the alternative scenario of boson-star signals being present in the data stream. […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Angela Adamo, Hakim Atek, Micaela B. Bagley, Eduardo Bañados, Kirk S. S. Barrow | Summary: With stunning clarity, JWST has revealed the Universe’s first billion years. The scientific community is analyzing a wealth of JWST imaging and spectroscopic data from that era, and is in the process […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Jan Scholtz, Francesco D’Eugenio, Roberto Maiolino, Pablo G. Pérez-González, Chiara Circosta | Summary: JWST is discovering increasing numbers of quiescent galaxies 1–2 billion years after the Big Bang, whose redshift, high mass, and old stellar ages indicate that their formation and quenching were surprisingly rapid. This fast-paced […]
