abstract
We present photometric redshifts for an uniquely large and deep sample of 522286 objects with i'_{AB}<25 in the Canada-France Legacy Survey ``Deep Survey'' fields, which cover a total effective area of 3.2 deg^2. We use 3241 spectroscopic redshifts with 0<z<5 from the VIMOS VLT Deep Survey as a calibration to derive these photometric redshifts. We devise a robust calibration method which removes systematic trends in the photometric redshifts and significantly reduces the fraction of catastrophic errors. We use our unique spectroscopic sample to present a detailed assessment of the robustness of the photometric redshift sample. For a sample selected at i'_{AB}<24, we reach a redshift accuracy of \sigma_{\Delta z/(1+z)}=0.037 with \eta=3.7% of catastrophic error. The reliability of our photometric redshifts is lower for fainter objects: we find \sigma_{\Delta z/(1+z)}=0.029, 0.043 and \eta=1.7%, 5.4% for samples selected at i'_{AB}=17.5-22.5 and 22.5-24 respectively. We find that the photometric redshifts of starburst galaxies in our sample are less reliable: although these galaxies represent only 18% of the spectroscopic sample they are responsible for 54% of the catastrophic errors. We find an excellent agreement between the photometric and the VVDS spectroscopic redshift distributions at i'_{AB}<24. Finally, we compare the redshift distributions of i' selected galaxies on the four CFHTLS deep fields, showing that cosmic variance is already present on fields of 0.8 deg^2.

A new redshift-correlation technique with third-generation GW detectors can constrain the BNS contribution to cosmic r-process nucleosynthesis to 5-6% precision via Fisher forecasts on mock bright- and dark-siren data.
A z=4.9 LAE protocluster exhibits 40% larger rest-optical sizes than field LAEs with no UV difference, indicating wavelength-dependent environmental influences on galaxy structure.
A score-based diffusion generative model on deep infrared galaxy photometry yields a star formation rate density peaking at z=1.3 and shows distinct non-parametric star formation histories plus AGN activity peaking during the quenching transition of massive galaxies.
A new catalogue of bar lengths and widths from HST images of 8230 galaxies shows bars are about 13% weaker at higher redshift, with longer bars in higher-mass quiescent galaxies and trends consistent with slow quenching.
UV/optical attenuation underpredicts IR luminosity by 3-10x across 0<z<7 while κ_UV/κ_FIR falls by over an order of magnitude, pointing to evolving dust grain properties in average galaxies.
A beta-VAE analysis of pop-cosmos models finds that five latent dimensions capture the rest-frame optical SED, corresponding to stellar mass, recent star formation, dust, and two gas ionization states.
Corrected empirical limits show the most massive galaxies never exceed the theoretical baryonic maximum of 0.16 times halo virial mass, keeping observations consistent with LambdaCDM at all redshifts.
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.
Neural network classification with CRPS optimization produces calibrated photometric redshift PDFs for DESI Legacy and Pan-STARRS data, achieving σ_NMAD of 0.0153 on LSDR10 and outperforming regression methods.
CosmoPostProcess delivers simulation-calibrated radial corrections for projection-induced selection bias (20-40% amplitude near 1 h^{-1} Mpc) and baryonic effects in Euclid richness-selected cluster weak lensing profiles.
Quiescent galaxies cluster more strongly than star-forming ones by 0.5-1 dex after halo-mass matching, with one-halo conformity up to z~2 that disappears at higher redshifts.
Galaxy size-mass relations exhibit double power-law breaks at different pivot masses for quiescent versus bulge-dominated samples, coinciding with AGN activity scales.
The first circumgalactic dust reddening measurement from Rubin DP1 data finds A_V proportional to r_perp to the -1.8 power within 120 kpc, consistent with prior SDSS/KiDS/DES results despite 1000x smaller area and fainter foreground sample.
LAEs at z=2.4-4.5 are smaller and more starbursting than typical SFGs, with Lyα strength correlating negatively with size and positively with Sersic index and recent SFR ratio.
A z=2.96 protocluster in COSMOS shows +0.2 dex higher stellar masses, mild SFR enhancement in low-mass galaxies, and no rise in quiescent fraction compared to the field.
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.
The SFR-M_* relation develops a high-mass decline at low redshifts, driven mainly by morphological quenching from internal structure rather than environmental effects on star-forming galaxies.
New catalog identifies 30,345 mid-IR variable sources at ecliptic poles from NEOWISE data, with AGN dominating in the north and stars in the south plus three transients linked to obscured QSOs.
Pantheon+ releases 1701 light curves from 1550 spectroscopically confirmed Type Ia supernovae across 18 surveys for cosmological inference.
Photometric redshift uncertainties bias Anderson-Darling and Gaussian-mixture tests toward relaxed cluster classifications, with Gaussian errors producing ~95% relaxed recovery versus ~5% for unrelaxed clusters.
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.
New early multi-wavelength data on GRB 230328B shows afterglow with early bump and late achromatic rebrightening at ~4000 s, modeled via MCMC as forward shock plus late energy injection in a dusty S0 host with AV~0.8 and no supernova signature.
Spectroscopic confirmation of one z=7.96 LBG in ~4.8 arcmin² COSMOS field yields surface density ~0.21 arcmin⁻², ~10× higher than photometric surveys, hinting at overdensity.
