Balmer Absorption Series and Broad Metal Lines in Two Luminous Little Red Dots

Bingjie Wang, Jenny E. Greene, Hanpu Liu +21

Balmer absorption is common among little red dots (LRDs), but absorbers at or redward of systemic are rare, occurring in only \% of H absorbers. In this paper, we stu…

Unified modelling of broad and narrow optical-UV emission lines from massive black holes: interpreting high-redshift JWST observations

Adele Plat, Michaela Hirschmann, Emma Curtis-Lake +10

JWST is uncovering a large population of active galactic nuclei (AGN) at high redshift, motivating the extension of models calibrated on local sources to a broader range of physica…

SPURS: Massive Stars, Dense Gas, and Ly Escape in GN-z11 at

Zuyi Chen, Daniel P. Stark, Charlotte A. Mason +6

We present ultra-deep {\it JWST} spectroscopy of GN-z11 () obtained through the SPURS Cycle 4 Large Program, providing the deepest rest-UV view yet obtained of a galaxy at…

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…

RUBIES: The Evolution of the Ionization Parameter from 0 < z < 9

Nikko J. Cleri, Zach J. Lewis, Joel Leja +10

The dimensionless ionization parameter, U=q/c, where q is the ratio of the local ionizing photon flux to the local hydrogen density, is a key metric to parameterize nebular conditi…

Origins of Extreme Emission-Line Ratios in z > 3 Galaxies: Insights from the Lumen Model

Lucie Scharré, Michaela Hirschmann, Adèle Plat +10

Optical emission-line ratios in star-forming galaxies at -8, such as [OIII]/H and [OIII]/[OII], are strongly offset from those at -2, pointing to more extrem…

SPURS: Bursty Star Formation in an Extremely Luminous Weak Emission Line Galaxy at

Zuyi Chen, Daniel P. Stark, Charlotte A. Mason +8

JWST has revealed a population of super-luminous early galaxies with a volume density in excess of most expectations. The spectra reveal diverse properties: while some reveal stron…
