Rapid, out of equilibrium metal enrichment indicated by a flat mass-metallicity relation at z~6 from NIRCam grism spectroscopy
Gauri Kotiwale, Jorryt Matthee, Daichi Kashino +17
We aim to characterise the mass-metallicity relation (MZR) and the 3D correlation between stellar mass, metallicity and star-formation rate (SFR) known as the fundamental metallici…
Little Red Dots host Black Hole Stars: A unified family of gas-reddened AGN revealed by JWST/NIRSpec spectroscopy
Anna de Graaff, Raphael E. Hviding, Rohan P. Naidu +34
We use the DAWN JWST Archive to construct and characterise a sample of 146 little red dots (LRDs) across 2.0<z<9.3, selecting all sources with v-shaped UV-optical continua from NIR…
The slope and scatter of the star forming main sequence at z~5 : reconciling observations with simulations
Claudia Di Cesare, Jorryt Matthee, Rohan P. Naidu +17
Galaxies exhibit a tight correlation between their star-formation rate and stellar mass over a wide redshift range known as the star-forming main sequence (SFMS). With JWST, we can…
The warm outer layer of a Little Red Dot as the source of [Fe II] and collisional Balmer lines with scattering wings
Alberto Torralba, Jorryt Matthee, Gabriele Pezzulli +22
The population of the Little Red Dots (LRDs) may represent a key phase of supermassive black hole (SMBH) growth. A cocoon of dense excited gas is emerging as key component to expla…
Irony at z=6.68: a bright AGN with forbidden Fe emission and multi-component Balmer absorption
Francesco D'Eugenio, Erica Nelson, Xihan Ji +11
We present the deepest medium-resolution JWST/NIRSpec spectroscopy to date of a bright Little Red Dot (LRD) AGN, Irony at z=6.68. The data reveal broad Balmer emission from H-H$…
Diversity and Evolution of Dust Attenuation Curves from Redshift z ~ 1 to 9
Irene Shivaei, Rohan P. Naidu, Francisco Rodriguez Montero +23
The UV-optical dust attenuation curve is key to interpreting the intrinsic properties of galaxies and provides insights into the nature of dust grains and their geometry relative t…
A weak Ly halo for an extremely bright Little Red Dot: Indications of enshrouded SMBH growth
Alberto Torralba, Jorryt Matthee, Gabriele Pezzulli +13
The abundant population of "Little Red Dots" (LRDs)-compact objects with red UV to optical colors and broad Balmer lines at high redshift-is unveiling new insights into the propert…
A "Black Hole Star" Reveals the Remarkable Gas-Enshrouded Hearts of the Little Red Dots
Rohan P. Naidu, Jorryt Matthee, Harley Katz +48
The physical processes that led to the formation of billion solar mass black holes within the first 700 million years of cosmic time remain a puzzle. Several theoretical scenarios…
