JADES Ultra-red Flattened Objects: Morphologies and Spatial Gradients in Color and Stellar Populations

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Justus L. Gibson, Erica Nelson, Christina C. Williams, Sedona H. Price, Katherine E. Whitaker | Summary: One of the more surprising findings after the first year of JWST observations is the large number of spatially extended galaxies (ultra-red flattened objects, or UFOs) among the optically-faint galaxy population […]

GA-NIFS: Multi-phase outflows in a star-forming galaxy at $z sim 5.5$

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Eleonora Parlanti, Stefano Carniani, Giacomo Venturi, Rodrigo Herrera-Camus, Santiago Arribas | Summary: Galactic outflows driven by star formation or active galactic nuclei are typically formed by multi-phase gas whose temperature spans over 4 orders of magnitude. Probing the different outflow components requires multi-wavelength observations and long exposure […]

PKS 2131-021 — Discovery of Strong Coherent Sinusoidal Variations from Radio to Optical Frequencies: Compelling Evidence for a Blazar Supermassive Black Hole Binary

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Sebastian Kiehlmann, Philipe Vergara De La Parra, Andrew Sullivan, A. Synani, Ioannis Liodakis | Summary: Haystack and Owens Valley Radio Observatory (OVRO) observations recently revealed strong sinusoidal total flux density variations that maintained coherence between 1975 and 2021 in the blazar PKS 2131-021 ($z=1.283)$. This was interpreted […]

JADES — The Rosetta Stone of JWST-discovered AGN: deciphering the intriguing nature of early AGN

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Ignas Juodžbalis, Xihan Ji, Roberto Maiolino, Francesco D’Eugenio, Jan Scholtz | Summary: JWST has discovered a large population of Active Galactic Nuclei (AGN) at high redshift. Many of these newly discovered AGN have broad permitted lines (typically H$alpha$), but are extremely weak in the X-rays. Here we […]

GA-NIFS: the interplay between merger, star formation and chemical enrichment in MACS1149-JD1 at z=9.11 with JWST/NIRSpec

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Cosimo Marconcini, Francesco D’Eugenio, Roberto Maiolino, Santiago Arribas, Andrew J. Bunker | Summary: We present JWST/NIRSpec integral-field spectroscopy observations of the z ~ 9.11 lensed galaxy MACS1149-JD1, as part of the GA-NIFS programme. The data was obtained with both the G395H grating (R~ 2700) and the prism […]

Rising from the ashes: evidence of old stellar populations and rejuvenation events in the very early Universe

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Callum Witten, William McClymont, Nicolas Laporte, Guido Roberts-Borsani, Debora Sijacki | Summary: While JWST has observed galaxies assembling as early as $zsim14$, evidence of galaxies with significant old stellar populations in the Epoch of Reionisation (EoR) — the descendants of these earliest galaxies — are few and […]

A massive, neutral gas reservoir permeating a galaxy proto-cluster after the reionization era

Kavli Affiliate: Debora Sijacki | First 5 Authors: Kasper E. Heintz, Jake S. Bennett, Pascal A. Oesch, Albert Sneppen, Douglas Rennehan | Summary: Galaxy clusters are the most massive, gravitationally-bound structures in the Universe, emerging through hierarchical structure formation of large-scale dark matter and baryon overdensities. Early galaxy “proto-clusters” are believed to be important physical […]

Cosmological constraints from the cross-correlation of DESI Luminous Red Galaxies with CMB lensing from Planck PR4 and ACT DR6

Kavli Affiliate: Blake Sherwin | First 5 Authors: Noah Sailer, Joshua Kim, Simone Ferraro, Mathew S. Madhavacheril, Martin White | Summary: We infer the growth of large scale structure over the redshift range $0.4lesssim z lesssim 1$ from the cross-correlation of spectroscopically calibrated Luminous Red Galaxies (LRGs) selected from the Dark Energy Spectroscopic Instrument (DESI) […]
