A Rapid Evolution in the Observed Mbh/M* Relation at z > 3 Revealed via Spectro-photometric SED-Modeling
Ansh R. Gupta, Anthony Taylor, Emma Curtis-Lake +33
Spectroscopic observations from JWST have uncovered a plethora of active galactic nuclei (AGN) at z > 4 with black hole (BH) mass (Mbh) to stellar mass (M*) ratios significantly ab…
Metal Mayhem at : Diversity and Evolution of Gas-Phase Metallicity Gradients
Maria Koller, Roberto Maiolino, Hannah Ãbler +16
We present a JWST/NIRSpec-IFU study of metallicity gradients in seven low-metallicity systems at . The main sample spans stellar masses of $\rm \log(M_*/M_{\odot}) \sim…
Consistent Gas-Phase Temperatures and Metallicities from UV and Optical Nebular Emission: A Reliable Foundation from z=0 to Cosmic Dawn
Erin Huntzinger, Yuguang Chen, Tucker Jones +6
The rest-frame UV spectra of star-forming galaxies are increasingly important as they become one of the primary windows to probe the physical properties of cosmic dawn (z>8) galaxi…
GA-NIFS: Dissecting The Alchemised: JWST reveals turbulent metal-poor gas fuelling a co-spatial starburst in a complex system at
Robert G. Pascalau, Francesco D'Eugenio, Roberto Maiolino +26
Recent observations revealed that distant galaxies have bursty star formation histories, regulated by stellar or active galactic nuclei (AGN) feedback and gas inflows. According to…
