What sets the star-formation rate in the Milky Way?. II. Comparing the star-forming clumps from simulations and observations
Linking the star formation (SF) properties of dense clumps to their parent large-scale environment is a key step to interpret Galactic surveys.The Cosmic Ultraviolet Baryon Survey X: Density and Pressure Profiles of Clumpy Circumgalactic Gas at $z=0.4-0.7$
The thermodynamic state and turbulent properties of the cool circumgalactic medium (CGM) are investigated for 23 galaxies and galaxy groups at intermediate redshift ($z=0.4$--0.7) in the Cosmic…Heavy Seeds and the Multi-scale Fueling of Early Supermassive Black Holes and Little Red Dots
The formation of supermassive black holes (SMBHs) in the early Universe has been a longstanding mystery due to the brief period available to assemble them.Protostellar Outflows at the EarliesT Stages (POETS) X. Preliminary statistics of 6.7 GHz masers near POETS sources
So far, the POETS survey has focused on studying at high angular resolution the properties of both 22.2 GHz H2O masers and the radio continuum emission near young stellar objects (YSOs).The inner galaxy as a window on its early assembly: lessons from a cosmological Milky Way analogue
Characterising the assembly history of the inner Milky Way is a key goal of upcoming spectroscopic surveys, yet disentangling its overlapping stellar components remains challenging.Unveiling the nonthermal environments of NGC 3411 and NGC 5903 through new MeerKAT observations
Galaxy groups are key laboratories for investigating the interplay between active galactic nucleus (AGN) outbursts and the dynamical processes of the intra-group medium.Testing Pre-main-sequence Evolutionary Models with Gaia and SPHEREx Observations of Canis Major North
Pre-main-sequence (PMS) evolutionary models can assign different ages across stellar mass within the same population.NOCTURNE. VI. Hour-timescale radio variability in early-stage active galactic nucleus SDSS J122844.81+501751.2
Recently, a sample of radio-weak active galactic nuclei (AGN) was discovered to exhibit extreme Jy-level radio flares at 37~GHz.Impact of Gaia-Sausage-Enceladus Debris on Milky Way Escape-velocity Estimates in TNG50
The escape velocity is a key probe of the Milky Way (MW) potential, but standard estimates can be biased by unrelaxed substructures.The formation of silicon-carbon chain molecules in IRC+10216
Linear silicon-carbon chain molecules, SiC$_n$ (n = 3--6), have been detected in the circumstellar envelope of the carbon-rich AGB star IRC+10216.Properties of Oxygen-rich Asymptotic Giant Branch stars in the LMC and the Milky Way
We investigate the properties of oxygen-rich asymptotic giant branch (OAGB) stars in the LMC and the Milky Way using infrared (IR) color-magnitude diagrams, two-color diagrams, spectral energy…Observational evidence of the Gaia-Enceladus-Sausage merger's influence on the opposite side of the Galactic Center
The Gaia-Enceladus-Sausage (GES) merger, which occurred approximately 8-11 Gyr ago, is a key event that shaped the Galactic inner halo.Polar-structure galaxies beyond the local Universe: first results from Euclid
Galaxies hosting strongly misaligned stellar and gas structures offer a direct window into external accretion and the buildup of angular momentum through multiple spin components.AllBRICQS: the All-sky BRIght, Complete Quasar Survey - Quasar Selection and Final Southern $G_{\rm RP}<16$ Sample
We describe the final quasar sample from the Southern part of the All-sky BRIght, Complete Quasar Survey (AllBRICQS), which aimed to discover the remaining optically bright quasars using data from…A MAGNHIFFIC cold-gas filament fuelling the nuclear activity of NGC 3100
MAGNHIFFIC (MeerKAT AGN HI Feeding & Feedback Investigation close-by) leverages on sensitive MeerKAT 21-cm and VLT Survey Telescope (VST) observations of nearby Active Galactic Nuclei (AGN) to study…Post-fragmentation Morphological and Broadband Color Evolution of C/2025 K1 (ATLAS)
Comet C/2025 K1 (ATLAS) underwent major fragmentation after its 2025 October 8 perihelion passage at q ~ 0.33 au.EP241021a as An Off-nuclear Month-duration Transient in a Dwarf Starburst Galaxy
EP241021a is a peculiar fast X-ray transient exhibiting a long X-ray plateau and an optical rebrightening, both challenging the traditional jet afterglow model.Contributions of massive stars and classical novae to Galactic 26Al
The radioactive isotope 26Al is believed to be mainly produced by massive stars and ejected into the interstellar medium through their winds and supernovae.The origin and distribution of diffuse HI in the close interacting MHONGOOSE galaxy systems
We present the deepest HI observations of the two systems with Dproj < 100 kpc, and $Δ$ vsys < 200 km/s in the MHONGOOSE survey.ePNGCAT: the first eROSITA all-sky data release
The eROSITA telescope array aboard the joint German--Russian Spektrum-Roentgen-Gamma (SRG) mission delivered the deepest soft all-sky X-ray survey to date, scanning the entire sky more than four…
