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…
Lyman- Escape through Anisotropic Media
Silvia Almada Monter, Max Gronke, Seok-Jun Chang
The escape of Lyman- (Ly) radiation encodes valuable information on the neutral interstellar medium and is often used as a proxy for the escape of ionizing photons. Yet, the…
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…
Simulating realistic Lyman- emitting galaxies including the effect of radiative transfer
Hasti Khoraminezhad, Shun Saito, Max Gronke +1
We present an empirical yet physically motivated simulation of realistic Lyman- emitters (LAEs) at , crucial for ongoing and forthcoming cosmological LAE surveys. We c…
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…
Disentangling the galactic and intergalactic components in 313 observed Lyman-alpha line profiles between redshift 0 and 5
Siddhartha Gurung-López, Chris Byrohl, Max Gronke +5
Lyman-Alpha (Lya) photons emitted in star-forming galaxies undergo complex radiative transfer through the interstellar (ISM), circumgalactic (CGM), and intergalactic medium (IGM),…
Constraining the geometry of the gas surrounding a typical galaxy at with Ly polarization
A. Bolamperti, S. -J. Chang, J. Vernet +6
Ly emission is the strongest tracer of recombining ionized hydrogen in young, star-forming galaxies, but its origin is still debated. Ly arises when emitted photons scatter i…
zELDA II: reconstruction of galactic Lyman-alpha spectra attenuated by the intergalactic medium using neural networks
Siddhartha Gurung-Lopez, Chris Byrohl, Max Gronke +5
The observed Lyman-Alpha (Lya) line profile is a convolution of the complex Lya radiative transfer taking place in the interstellar, circumgalactic and intergalactic medium (ISM, C…
