Hidden Disruption in Milky Way-like Satellite Galaxy Populations
Determining whether a satellite galaxy is tidally disrupting from photometric observations alone remains a fundamental challenge in near-field cosmology.The bar-driven central complex of NGC 6946: A panchromatic and spatially resolved view of its star formation history and interstellar medium
We present a multi-wavelength analysis of the nearby spiral galaxy NGC 6946, combining optical IFS, infrared, and radio observations.Contrasting geometries of kiloparsec-scale stellar flows associated with giant Galactic cavities
Giant bubbles and cavities are widespread in star-forming galactic discs, yet the stellar dynamics associated with such structures remain poorly constrained.Let Sleeping Stars Li: Mapping Turnoff Lithium, the Lithium Dip, & Testing Standard Model Predictions in GALAH DR4 Subgiants
Lithium is an excellent tracer of stellar mixing.Searching for Dwarf Novae in 47 Tucanae
The globular cluster 47 Tucanae has 43 strong cataclysmic variable candidates, four of which are confirmed dwarf novae.The Magnetized Universe: From planet-forming disks to the high-redshift universe
The interstellar medium (ISM) is magnetized at all scales and phases in our Galaxy and other galaxies across the Universe.Double Trouble: How Unresolved Spectroscopic Binary Stars Skew GALAH DR4 Stellar Parameters
Unresolved binary stars introduce systematic biases in stellar parameter estimates when analysed assuming a single star.Hot Molecular Hydrogen in Galaxies at Redshift ~ 0.2-1.5 Revealed by JWST
Molecular hydrogen (H$_2$) is the fundamental component of the molecular gas reservoir that fuels star formation and black hole growth.Large-scale Environmental Dependence of AGN Activity Revealed by JWST Pa$α$ Emitters
The role of the large-scale environment in regulating AGN activity remains an open question.Simulations of Dust Content and Attenuation in $z=5-15$ Galaxies
Correctly modeling the dust attenuation law in galaxies is essential to properly inferring their growth and physical properties.Barflow: Modeling Gas Kinematics of Bar-Driven Flows
We present self-consistent $N$-body/hydrodynamical simulations of isolated, Milky Way-like galaxies with stellar and gaseous disks.Microcaustics: Fast GPU-Accelerated Dynamical Microlensing of Time-Dependent Extended Sources
Gravitational microlensing probes unresolved quasar accretion disc structure and compact objects in lens galaxies and is an important systematic in strong-lens time-delay cosmography.Identifying Planetary Nebulae Candidates from IPHAS and VPHAS+ Surveys via YOLO Deep Learning Models
We present a deep learning detection method capable of effectively identifying planetary nebulae (PNe) on IPHAS and VPHAS+ surveys.Large dust grains escaping from a supernova remnant
Dust grains produced in the supernova (SN) ejecta at early ages are partially destroyed in hot gas of the SN remnant.Strong gravitational lensing with Euclid
Euclid data is going to lead to the discovery of approximately 10^5 new strong gravitational lenses, thereby increasing the number of known lenses by a factor of 30.A heterogeneous set of unusual quasars selected from astrometry and broad-band photometry
The aim of this study is to explore methods for how to identify new quasars with different properties with regard to reddening, redshift, the presence of broad absorption lines from outflows, or…specwizard: A Public Python Framework for Creating Synthetic Absorption Spectra from Hydrodynamical Simulations
We present specwizard, a publicly available modular Python package for generating synthetic absorption spectra from hydrodynamical simulations.Black Hole Binary Mergers in Galactic Nuclei: Combined Effects of Secular Dynamics and Stellar Flybys
Galactic nuclei, with the central supermassive black holes (SMBHs) and surrounding dense star clusters, serve as natural laboratories for studying gravitational dynamics in extreme gravitational…PDRs4All XXIII. JWST-MIRI template spectra of PAHs in the Orion Bar obtained with blind signal separation
The aromatic infrared bands (AIBs) are observed in a wide variety of astrophysical sources, and now in unprecedented detail by the James Webb space telescope (JWST).Sleeping or Dead? Probing the Quenching Mechanism of JWST Dormant Galaxies at z > 3 with ALMA
JWST has revealed a population of "dormant'' galaxies at z>3 with strong Balmer breaks and weak emission lines, whose star formation appears to have declined only recently.
