abstract
Announcing the final release, v8, of the Milliquas (Million Quasars) quasar catalogue which presents all published quasars to 30 June 2023, including quasars from the first releases of the Dark Energy Spectroscopic Instrument (DESI) and the SDSS-DR18 Black Hole Mapper. Its totals are 907,144 type-I QSOs/AGN and 66,026 high-confidence (~99% likelihood) radio/X-ray associated quasar candidates. Type-II and Bl Lac type objects are also included, bringing the total count to 1,021,800. Gaia-EDR3 astrometry is given for most objects. The catalogue is available on NASA HEASARC and CDS and on its home page.

Forecasts ~thousands of FRB-QSO pairs at <10' separation by 2035 for CGM, cosmic web, and Milky Way halo studies with HST/COS.
Multiphase observations show molecular gas mass loading factors 10 times higher than ionised gas in ESO 484-036, creating a 3.5 dex discrepancy with cosmological simulations that underpredict cold gas outflows.
Presents a public spectroscopic atlas of 887 Southern broad-line AGNs at low redshift, including continuum decompositions and emission-line fits.
The DECam Shadow Survey has detected variable LBV eruptions in AT2017des with peaks brightening by ~0.05 mag per year, reaching luminosities similar to extreme SN impostors.
Six new Galactic radio transients found and classified into two types, proposed to originate from wide-orbit white dwarf binaries.
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.
BOOM is a new high-throughput alert broker using Rust, MongoDB, Valkey and Kafka that matches prior ZTF features at ~7x speed and is extended as Babamul for LSST's 20 million nightly alerts.
Systematic search of ZTF DR23 data yields catalogs of 28,504 coarse and 1,984 refined AGN flares with public release.
Using ZTF DR2 data, AGN presence in Type Ia supernova host galaxies at z<0.15 shows no significant systematic effect on Hubble residuals.
Archival Chandra and XMM-Newton observations reveal two transient X-ray sources in NGC 4552 exceeding 10^39 erg/s, classifying them as new transient ULXs.
A single galaxy cluster lenses two quasars (one Type I at z=1.524, one dust-obscured Type II at z=1.939) into four images each, yielding a projected mass of ~3.3e14 solar masses within 500 kpc and time delays of hundreds to over 1000 days.
Dwarf galaxies host compact thermal HII regions powered by up to 100,000 O-type stars and exhibit radio variability consistent with AGNs.
Hα luminosity functions at z~1.3 and z~2.0 yield faint-end slopes of -1.50 and -1.60, with integrated SFR densities of 0.097 and 0.129 M⊙ yr⁻¹ Mpc⁻³ from a sample of 99 emitters.
A Random Forest classifier on Chandra, Gaia, and CatWISE data identifies 1060 new quasar candidates behind the Galactic plane, with two spectroscopically confirmed at z~1.1-1.3.
LAMOST DR10-12 adds 11,346 quasars (5,386 new) with ZTF-recalibrated spectra and derived emission-line and black-hole mass properties to support variability and rare-object studies.
Synthesizes simulation predictions and pathfinder data to outline a broadband radio SED and spectral curvature strategy for identifying the earliest radio AGN with the SKA.
Expanding HST observations of intermediate-redshift quasars can deliver the first systematic rest-frame EUV census of QSOs and warm-hot gas in the CGM/IGM as a low-redshift anchor for future UV missions.
