High-redshift quasars are thought to live in the densest regions of space, which should be
made evident by an overdensity of galaxies around them. However, campaigns to identify …

We present a study on stellar properties of Lyman-alpha (Ly α) emitters at 5< z< 8.2. We use
247 photometrically selected, lensed, high-redshift, low-luminosity galaxy candidates with …

The Lyα emission line is a characteristic feature found in high-z galaxies, serving as a probe
of cosmic reionization. While previous works present various correlations between Lyα …

The detections of Lyα emission in galaxies with redshifts above 5 are of utmost importance
for constraining the cosmic reionization timeline, yet such detections are usually based on …

Thanks to decades of observations using HST, the structure of galaxies at redshift $ z> 2$
has been widely studied in the rest-frame ultraviolet regime, which traces recent star …

We investigate the correlation between stellar mass (M*) and star formation rate (SFR)
across the stellar mass range log10 (M*/Msun)~ 6-11. We consider almost 50,000 star …

Making use of JWST NIRSpec and NIRCam data, we conduct a detailed analysis of the
spectroscopic and photometric properties of GN-z8-LAE, a strong Lya emitter at z= 8.279 …

We present Virgil, a MIRI extremely red object (MERO) detected with the F1000W filter as
part of the MIRI Deep Imaging Survey (MIDIS) observations of the Hubble Ultra Deep Field …

Blind spectroscopy of massive lensing galaxy clusters with MUSE has revealed large
numbers of gravitationally-lensed Lyman-$\alpha $ emitters exhibiting asymmetric profiles at …

Ly-α emitting galaxies (LAEs) are usually detected via their intense UV emission lines, thus
generally considered blue, low-mass objects. However, recent studies have revealed the …
