Rapid emergence of overmassive black holes in the early Universe
Sunmyon Chon, Shingo Hirano, Tomoaki Ishiyama +2
The origin of supermassive black holes (SMBHs) remains a long-standing problem in astrophysics. Recent JWST observations reveal an unexpectedly abundant population of overmassive b…
Impact of Resonance, Raman, and Thomson Scattering on Hydrogen Line Formation in Little Red Dots
Seok-Jun Chang, Max Gronke, Jorryt Matthee +1
Little Red Dots (LRDs) are compact sources at discovered through JWST spectroscopy. Their spectra exhibit broad Balmer emission lines (), alongside…
Ruling out dominant electron scattering in Little Red Dots' Rosetta Stone using multiple hydrogen lines
Matilde Brazzini, Francesco D'Eugenio, Roberto Maiolino +3
The majority of Little Red Dots (LRDs) hosting Active Galactic Nuclei (AGN) exhibits broad H emission, which recent studies propose originates from scattering off free electrons…
Evidence of a Disk-wind Origin for Fluorescent H in Classical T Tauri Stars
Matt Kalscheur, Kevin France, Brunella Nisini +8
We use FUV spectra of 36 T Tauri stars, predominately from 's ULLYSES program, to examine the kinematic properties of fluorescent H emission li…
Modeling Mg II resonance doublet spectra from galaxy haloes at z 1
Seok-Jun Chang, Rajeshwari Dutta, Max Gronke +3
We investigate the properties of cold gas at around star-forming galaxies at using Mg II spectra through radiative transfer modeling. We utilize a comprehen…
A Model of the C IV 1548, 1550 Doublet Line in T Tauri Stars
Thanawuth Thanathibodee, Connor Robinson, Nuria Calvet +7
The C IV doublet in the UV has long been associated with accretion in T Tauri stars. However, it is still unclear where and how the lines are formed. Here, we present a new C IV li…
