MOSEL Survey: Spatially Offset Lyman-continuum Emission in a New Emitter at z = 3.088 Can Explain the Low Number Density of Observed LyC Leakers

The Astrophysical Journal
We present the discovery of a unique Lyman-continuum (LyC) emitter at z = 3.088. The LyC emission was detected using the Hubble Space Telescope WFC3/UVIS F336W filter, covering a rest-frame wavelength range of 760–900 Å. The peak signal-to-noise ratio of

The Stellar Origin of “V-shaped” Spectral Energy Distributions in Lyα-emitting Little Red Dots Revealed by JWST/MIRI

The Astrophysical Journal
Understanding the nature of the high-redshift “V-shaped” little red dots (LRDs) recently uncovered by the James Webb Space Telescope (JWST) is crucial for constraining the early coevolution of galaxies and supermassive black holes (SMBHs).

Disentangling the galactic and intergalactic components in 313 observed Lyman-alpha line profiles between redshift 0 and 5

The Open Journal of Astrophysics
Lyman-Alpha (Ly$\alpha$) photons emitted in star-forming galaxies undergo complex radiative transfer through the interstellar (ISM), circumgalactic (CGM), and intergalactic medium (IGM), imprinting characteristic signatures on their observed line ...

Lyman-alpha Cooling Emission from Galaxy Formation

, 2010
Recent studies have shown that galaxies accrete most of their baryons via the cold mode, from streams with temperatures T~10^4-10^5 K. At these temperatures, the streams should radiate primarily in the Lya line and have therefore been proposed as a model to power the extended, high-redshift objects known as Lya blobs and other high-redshift Lya sources.

Deciphering Spatially Resolved Lyman-Alpha Profiles in Reionization Analogs: The Sunburst Arc at Cosmic Noon

The Open Journal of Astrophysics
The hydrogen Lyman-alpha (Ly$\alpha$) emission line, the brightest spectral feature of a photoionized gas, is considered an indirect tracer of the escape of Lyman continuum (LyC) photons, particularly when the intergalactic medium is too opaque for ...
