A Cosmic Archipelago of lensed metal-poor galaxies at
A. Bolamperti, M. Messa, A. Zanella +21
The Cosmic Archipelago is an ensemble of galaxies, strongly lensed by the cluster MACSJ0416, showing extreme physical properties at . We combine JWST/NIRCam with deep VL…
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),…
SPURS: Evidence for Clumpy Neutral Envelopes and Ionized IGM Surrounding Little Red Dots in Abell 2744 from Ultra-Deep Rest-UV Spectroscopy
Mengtao Tang, Daniel P. Stark, Charlotte A. Mason +14
Rest-frame ultraviolet (UV) spectra of Little Red Dots (LRDs) often show Ly emission. Along with broad Balmer emission, LRDs are expected to produce broad Ly emission. Howe…
The MUSE Ultra Deep Field (MUDF) VIII. The cool gas distribution surrounding galaxies at redshifts z ~ 0.5-2
Edoardo Santo, Michele Fumagalli, Seok-Jun Chang +5
We use deep MUSE data from the MUDF survey to investigate the cool gas around galaxies at redshifts 0.5 < z < 2. We constructed two samples: one sample for a down-the-barrel analys…
The Engine and its Flows: Little Red Dot spectra are shaped by the column densities of their gas envelopes
Jorryt Matthee, Alberto Torralba, Gabriele Pezzulli +23
JWST data have enabled the abundant identification of compact broad Balmer line sources nicknamed the Little Red Dots. While they share broad lines with active galactic nuclei, the…
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, th…
