abstract
We give an overview of the Galaxy Evolution Explorer (GALEX), a NASA Explorer Mission launched on April 28, 2003. GALEX is performing the first space UV sky-survey, including imaging and grism surveys in two bands (1350-1750 Angstroms and 1750-2750 Angstroms). The surveys include an all-sky imaging survey (m[AB] ~ 20.5), a medium imaging survey of 1000 square degrees (m[AB] ~ 23), a deep imaging survey of 100 square degrees (m[AB] ~ 25), and a nearby galaxy survey. Spectroscopic grism surveys (R=100-200) are underway with various depths and sky coverage. Many targets overlap existing or planned surveys. We will use the measured UV properties of local galaxies, along with corollary observations, to calibrate the UV-global star formation rate relationship in local galaxies. We will apply this calibration to distant galaxies discovered in the deep imaging and spectroscopic surveys to map the history of star formation in the universe over the redshift range 0 < z < 1.5, and probe the physical drivers of star formation in galaxies. The GALEX mission includes a Guest Investigator program supporting the wide variety of programs made possible by the first UV sky survey.

Domain adaptation with an ensemble of CNN and transformer models trained on DES detects 20,180 LSBGs and 434 UDGs in KiDS DR5, with structural parameters and environmental trends consistent with known samples.
LSST will image 18,000 square degrees of sky about 800 times across six bands over 10 years to a coadded depth of r~27.5, producing a public database of 40 billion objects and 32 trillion observations.
Stacked ultra-deep images of dwarf irregular galaxies reveal a pure exponential stellar disk extending to surface brightness of 32.3 mag/arcsec² without a detectable stellar halo, attributed to internal evolutionary processes.
The dust-obscured galaxy J1010+3725 hosts a complex ionized outflow consisting of five narrow components with velocities from -1475 to +507 km/s and high hydrogen densities above 10^5 cm^{-3}.
Dust attenuation follows a universal mass-dependent relation from z=0 to 7 with a transition at 10^9 solar masses where nebular attenuation steepens relative to stellar.
New ASKAP continuum imaging classifies jet morphologies in 173 G4Jy-3CRE sources (66% of sample) including 37 newly detected jets and identifies six new optical counterparts.
Hyrax is a GPU-enabled open-source framework for the full ML lifecycle in astronomy, with demonstrations of unsupervised discovery and classification on real survey data from Rubin, ZTF, and other projects.
Molecular gas in M83 consists of two log-normal density components, with the high-density component enhanced along spiral arms and more tightly linked to star formation than the low-density component.
Ca-rich gap transients and 91bg-like SNe occupy similar massive quiescent host parameter space with peak delay times around 10^4 Myr, unlike normal Type Ia (~10^3 Myr) and Type II (~10 Myr) SNe.
Local compact AGN-hosting dwarf galaxies with V-shaped SEDs are more evolved than high-redshift Little Red Dots, indicating distinct formation pathways.
TOI-1710 b has a true obliquity of 149 degrees indicating retrograde motion, favoring high-eccentricity migration via planet-planet scattering and Kozai-Lidov cycles for this tidally detached super-Neptune.
Massive quiescent galaxies at high redshifts show elevated fractions in small-scale overdensities, indicating environmental quenching via galaxy interactions plays a major role.
Pantheon+ releases 1701 light curves from 1550 spectroscopically confirmed Type Ia supernovae across 18 surveys for cosmological inference.
SED fitting plus kinematic diagnostics identify 182 top dormant BH/NS binary candidates from Gaia DR3, with 19 likely black hole systems having companion masses >=3 solar masses.
TOI-159 b is confirmed as the hottest known eccentric hot Jupiter (e = 0.24) with a 13-sigma Keplerian detection around a young gamma Doradus star, including a preliminary low-resolution transmission spectrum.
NIRCam-selected AGN hosts split into a 'bridge' group with moderate-to-low SFRs and a 'branch' group above the SFMS with SFR rising with AGN fraction; both populations show recent transitions between star formation and quiescence.
Panchromatic SED modeling yields SFRs with smaller offset and scatter than optical-only fits for starburst to post-starburst galaxies, while Prospector AGN torus models distinguish AGN but underpredict luminosities by an order of magnitude.
RX J1553.0+4457 is a detached post-common-envelope binary whose light curve shows ellipsoidal modulation from a tidally distorted M dwarf, with magnetic activity producing flares and declining X-ray emission, consistent with a white dwarf plus M dwarf SED and no clear accretion disk.
GAMA 376183 is a rare Eddington-limited heavily obscured AGN in a merging low-mass galaxy, triggered by the merger and identified via strong [Ne V] emission.
