Disk Structure May Determine AGN Variability and Explain the Accretion Disk Size Problem: No Broad Line Region Required
Variability is a crucial probe of active galactic nuclei (AGN) disks, but the impact of the structure and internal physics of the disk on this variability is poorly understood.A Single Line-Emitter Identified in an Unbiased Search with JWST/NIRSpec: Multi-Object Coronagraphy for Slitless Spectroscopy
We report the detection of a previously unknown object with a single emission line within the Hubble Ultra Deep Field, using a new JWST NIRSpec technique called Multi-Object Coronagraphy for…When dust growth takes over: the origin of dust in post-reionization galaxies
The post-reionization epoch ($z\sim4$-6) marks a critical phase in galaxy evolution, during which galaxies rapidly assemble their stellar mass, enrich their interstellar medium, and build up…Exploring Case B I: The Footprints of Hidden Radiation Fields in H I Balmer Decrements
Theory predicts that H I emission from photoionized clouds should lie close to the Case B limit established by Menzel and Baker, and observations of nearby nebulae have largely confirmed this…Bridging Theory and Observation: Synthetic Far-infrared Insights into Star Formation Efficiency
The star formation efficiency per free-fall time ($ε_{\rm ff}$) quantifies how efficiently giant molecular clouds (GMCs) convert gas into stars and is often observed to be orders of magnitude lower…Predicted state-to-state collisional rate coefficients from neural networks
Molecular spectra observed in the interstellar medium are commonly analyzed using non-local thermodynamic equilibrium models, which requires accurate state-to-state collisional rate coefficients.Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS) V. Tracing cavity walls and shocked knots with nonthermally desorbed CH$_3$OH in BHR71-IRS1
Complex organic molecules are detected in both cold molecular clouds and the warm inner regions of protostars.ASTRAL: A Framework for Optimal Placement and Emulation of Stellar Evolution Models
Generating dense grids of detailed stellar evolution simulations is computationally prohibitive, as resolving progressively complex nucleosynthesis chains and dynamical timescales incurs a rapidly…Light curve spectral energy distribution fitting of 13 carbon-rich Mira variables stars in the Small Magellanic Cloud
Carbon-rich Mira variables are highly dynamic stars characterized by large-amplitude radial pulsations and intense mass-loss.SAGE26 Paper I: Modelling the baryon cycle from cosmic dawn to the present day
We present SAGE26, a comprehensive update to the Semi-Analytic Galaxy Evolution (SAGE) model.Registering Gaia positions on VLBI images: constraining opacity-driven core shift in B 1038+528 / B 1038+529
Because of the complex and time-variable radio structure of active galactic nuclei (AGNs), absolute astrometric positions cannot generally be registered unambiguously with specific features in VLBI…Star Formation in the Low Surface Brightness Galaxies: a Comparison with the Outer Regions of Normal Galaxies
Low surface brightness galaxies (LSB-galaxies) and the outer regions of disks of "normal" surface brightness galaxies (HSB-galaxies) are compared in terms of the radial distributions of star…On the origin of the short-period Blue Straggler Stars in Collinder 261: a binary evolution approach
Building on the recent publication of a fresh catalog of blue straggler stars in Galactic open clusters using Gaia DR3, we conduct a study focusing on the blue straggler stars with short-period…Quasi-periodic eruption spectral-timing: EMRIs crossing warped accretion disks
Quasi-periodic eruptions (QPEs) are repeating X-ray transients from galactic nuclei potentially caused by a stellar-mass orbiter repeatedly colliding with the accretion disk of a supermassive black…MUSE-ALMA Haloes XIV: The ALMA Large Programme Data Release
The interactions between gas and galaxies are of paramount importance to our understanding of structure formation.MUSE-ALMA Haloes XV: Cold molecular, ionised, and stellar kinematics of HI-rich galaxies at z $\sim$ 0.5
Spatially resolved galaxy kinematics are well studied at z $\sim$ 0 and z > 1, revealing that disks are common out to z $\sim3-6$, albeit with higher velocity dispersions. z $\sim$ 0.5 marks a key…MUSE-ALMA Haloes XVI: a census of the condensed baryons in z~0.5 HI absorption-selected galaxies
We use the MUSE-ALMA Haloes sample to build a census of the condensed baryons (stars and cold gas) to study the multiphase interstellar medium and circumgalactic medium (CGM).IMFIT-MW: Multiwavelength photometric decomposition with IMFIT
Photometric decomposition is often used to study galaxy structure by modelling surface brightness distribution in its components.A Gravitationally Lensed Low-Luminosity AGN From The Cosmic Noon
Strong gravitational lensing provides a unique tool of studying intrinsically faint high-redshift active galactic nuclei (AGN).Two Low-Mass-Ratio Microlensing Planets from High-Magnification Events: KMT-2021-BLG-0247 and MOA-2023-BLG-169
We present an analysis of two planetary microlensing events, KMT-2021-BLG-0247 and MOA-2023-BLG-169, both of which exhibit high magnifications and low planet--host mass ratios, but with markedly…
