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 […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: William McClymont, Sandro Tacchella, Francesco D’Eugenio, Callum Witten, Xihan Ji | Summary: The peculiar nebular emission displayed by galaxies in the early Universe presents a unique opportunity to gain insight into the regulation of star formation in extreme environments. We investigate 500 (109) galaxies with deep NIRSpec/PRISM […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Gareth C. Jones, Andrew J. Bunker, Kseniia Telikova, Santiago Arribas, Stefano Carniani | Summary: We present observations of the $zsim5.7$ Lyman-break galaxy HZ10 with the JWST/NIRSpec IFU in high and low spectral resolution (G395H, $Rsim2700$ and PRISM, $Rsim100$, respectively), as part of the GA-NIFS program. By spatially […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Xihan Ji, Roberto Maiolino, Gary Ferland, Francesco D’Eugenio, Rachana Bhatawdekar | Summary: We report the detection of continuum excess in the rest-frame UV between 3000 {AA} and 3550 {AA} in the JWST/NIRSpec spectrum of GN-z11, a galaxy hosting an active galactic nucleus (AGN) at z = 10.603. […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Pablo G. Pérez-González, Francesco D`Eugenio, Bruno Rodríguez del Pino, Hannah Übler, Roberto Maiolino | Summary: Feedback is the key physical mechanism regulating galaxy formation. Stars in galaxies form when baryons radiatively cool down and fall into gravitational wells. Eventually, star formation quenches as gas is depleted and/or […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Roberto Maiolino, Guido Risaliti, Matilde Signorini, Bartolomeo Trefoloni, Ignas Juodzbalis | Summary: We investigate the X-ray properties of a large sample of 71 broad line and narrow line AGN at 2<z<11 discovered by JWST in the GOODS fields, which have the deepest Chandra observations ever obtained. Despite […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Calvin Preston, Alexandra Amon, George Efstathiou, , | Summary: Analyses of cosmic shear typically condense weak lensing information over a range of scales to a single cosmological parameter, $S_8$. This paper presents a method to extract more information from Stage-IV cosmic shear measurements by directly reconstructing the […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Jenny T. Wan, Sandro Tacchella, Benjamin D. Johnson, Kartheik G. Iyer, Joshua S. Speagle | Summary: The amount of power contained in the variations in galaxy star-formation histories (SFHs) across a range of timescales encodes key information about the physical processes which modulate star formation. Modelling the […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Katja Fahrion, Torsten Böker, Michele Perna, Tracy L. Beck, Roberto Maiolino | Summary: We present a detailed study of the centre of NGC4654, a Milky Way-like spiral galaxy in the Virgo cluster that has been reported to host a double stellar nucleus, thus promising a rare view […]
