X-ray AGN fraction among ALMA-selected DSFGs is enhanced by a factor of ~2.7 in seven z>2 protoclusters relative to a stellar-mass-, SFR-, and dust-mass-matched COSMOS field sample.

PITA, a new semi-supervised deep learning algorithm, outperforms prior photo-z methods by using a triple-task loss on images, colors, and available redshifts to produce a smooth latent space.
Euclid identifies 16 massive compact galaxies with V-shaped SEDs at z>4, half as old as the universe at their redshift, mostly distinct from known AGN.
PASSAGE releases 2183 spectroscopic redshifts (0.08<z<4.7) from JWST NIRISS observations in COSMOS, with strong agreement to photometric redshifts for multi-line sources and a quantified ~18% misidentification rate for single-line emitters.
Observational analysis of COSMOS galaxy groups shows quiescent fraction builds steadily from z~1.5-2 with faster growth in richer groups, first RS ridgeline galaxies by z~2, a possible early overdensity at z=3.4, and no significant evolution in RS slope or scatter.
Cross-correlation of CLAMATO Lyman-alpha forest with COSMOS galaxies yields stellar-mass-dependent biases of approximately 2.1, 3.2, and 3.8, corresponding to halo masses of log M_h ~ 10.5, 11.7, and 12.1 from Bolshoi-Planck mocks, with hints of enhanced low-mass star formation.
The N2CLS 2mm survey measures a mean S2/S1.2 color of 0.222 and mean redshifts of 3.2-3.6, finds no exotic 2mm-only population, and shows 2mm samples miss z~2 galaxies compared to 1.2mm samples.
Simulations show SPHEREx photometry is generally unbiased but source blending drives outliers; with brightness selection, photometric redshifts reach σ_NMAD ≈ 0.003-0.01 and cluster redshifts are recovered to |Δz|/(1+z) < 0.002 at z ≲ 0.5.
The NIKA2 survey delivers catalogs of 323 mm-selected sources in COSMOS with redshifts peaking at z=2.8, including 66 at z>4, matching SIDES simulations but inconsistent with four other galaxy evolution models.

Cross-correlations between the CLAMATO Lyman-alpha forest and galaxies within the COSMOS field
Cross-correlation of CLAMATO Lyman-alpha forest with COSMOS galaxies yields stellar-mass-dependent biases of approximately 2.1, 3.2, and 3.8, corresponding to halo masses of log M_h ~ 10.5, 11.7, and 12.1 from Bolshoi-Planck mocks, with hints of enhanced low-mass star formation.
