Kavli Affiliate: Anthony Lasenby | First 5 Authors: Will Barker, Michael Hobson, Anthony Lasenby, Yun-Cherng Lin, Zhiyuan Wei | Summary: The Poincar’e gauge theory (PGT) of gravity provides a viable formulation of general relativity (Einstein-Cartan theory), and a popular model-building framework for modified gravity with torsion. Notoriously, however, the PGT terms which propagate vector torsion […]

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 […]

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. […]
