Bar likelihood in local galaxies: the joint role of stellar mass, morphology and environment
We investigate how the likelihood of hosting a stellar bar depends on both intrinsic galaxy properties and environment, using a volume-limited sample of central and satellite galaxies from the…Collisional excitation of HMgC$_3$N by He: rate coefficients and astrophysical implications
Reliable collisional data are essential for interpreting the rotational emission of HMgC$_3$N under the non-equilibrium conditions of molecular clouds.The 943 MHz radio-SFR relation of nearby galaxies observed with ASKAP
We investigate the integrated 943 MHz radio-infrared and radio-star-formation-rate (SFR) relations of 875 nearby galaxies within $D<50$ Mpc using public Australian SKA Pathfinder (ASKAP) observations.Stellar Kinematics and Molecular Gas toward NGC 6357: An Overlooked Earlier Stellar Generation
We investigate past star formation in NGC 6357 using Gaia DR3 astrometry and Three-mm Ultimate Mopra Milky Way Survey (ThrUMMS) $^{12}$CO($J=1$--0) data.Formation of Micron-sized Presolar Graphite Grains in Low-energy Supernova Ejecta
Presolar graphite grains with supernova isotopic signatures provide direct evidence that large graphite grains formed in supernova ejecta.Developing Environments: Formation and Quenching at Cosmic Noon Traced by the Large-scale Distribution of Gas and Galaxies
Environmental density correlates with galaxy properties in the local Universe, but how and when these trends emerge is unclear: at cosmic noon, large-scale structures are still assembling and…EMBER: A Little Red Dot Candidate at $z_{\rm spec}=10.36$ in the Seed Black Hole Era
Little red dots (LRDs) are a newly discovered population that may trace rapidly growing black holes (BHs) and provide a link between seed BHs and luminous active galactic nuclei (AGNs).Hidden Neutrino Active Galaxy Candidates: Prospects for Catalog and Stacking Searches with IceCube, IceCube-Gen2, and KM3NeT
In high-energy neutrino astrophysics, the identification of high-energy neutrino sources is a central goal, and jet-quiet active galactic nuclei (AGNs) have emerged as promising candidates.MARTA: A "little" black hole hidden in a clumpy, metal-poor galaxy at z~3.8
JWST has extended the search for accreting black holes into the high-redshift, low-mass regime.A Supermagnified Little Red Dot with a Resolved Host
Little red dots (LRDs) are an intriguing new class of sources in the early universe discovered by the James Webb Space Telescope (JWST) characterized by V-shaped spectra and extremely compact sizes.Intranight optical monitoring of eight quasars with superluminal jets and low optical polarization: Probing the mechanism of rapid flux variability
Intranight optical variability (INOV) of blazars whose emission arises predominantly from a relativistic jet, has been widely linked to a combination of two key observational diagnostics: the…Dust-induced reversal of the optical wavelength dependence of spiral-arm pitch angles
The classical density-wave scenario predicts a blue-to-red age--colour gradient across the spiral arms of disc galaxies as a consequence of shock-induced star formation.The MAGPI Survey: the evolution of galaxy spin-filament alignments since z~0.3
We present measurements of galaxy spin-filament alignments at 0.20<z<0.42 using the MAGPI Survey, exploiting resolved stellar and ionised gas kinematics to reconstruct 3D spin axes.A VLT/CRIRES+ study of helium 1.083$μ$m absorption features towards the inner Orion Nebula
JWST NIRCam F115W observations towards the inner Orion Nebula revealed a diverse array of previously unknown dark features.Euclid Quick Data Release (Q1). Mass-to-light ratio of elliptical galaxies: constraints from strong lensing
Mass is among the most fundamental properties describing a galaxy.The L1157 filament as traced in HNCO by the LMT
The L1157 outflow is a prototype of chemically active outflows where to look for molecular species linked to complex chemistry.Modeling CO Line Luminosity with FIRE simulations: II. Comparison With Observations, CO Luminosity Functions and Redshift Evolution
We present predictions for the CO(1-0) and CO(2-1) luminosities of 765, 850, 887 and 915 galaxies at z=0, 1, 2 and 3, respectively, drawn from the Feedback in Realistic Environments (FIRE-2)…The Korean Space Telescope (KST): A Dedicated Space Observatory for the Dark Universe
The Korean Space Telescope (KST) is a next-generation 1.4-meter wide-field space observatory, a dedicated probe of the dark sector.A Low-Dimensional Chemical Representation of High-Resolution Stellar Disk Spectra: Residual Abundance Signatures
Stellar abundances are generated by complex chemical enrichment pathways yet show strong correlation structure.The origin of UV emission in extremely low-mass satellite galaxies: Insights from Leo T
Leo T, a Milky Way (MW) satellite, is the lowest-mass gas-rich galaxy known to show recent star formation, making it an excellent laboratory for investigating star formation in the ultraviolet (UV)…
