LIGHTS. Limitations of Far-Infrared Tracers for Galactic Cirrus Mitigation in the Era of Ultra-Deep Imaging
Current and forthcoming deep optical imaging surveys are reaching surface brightness levels fainter than 30 mag/arcsec$^2$, where Galactic cirrus emission becomes a significant contaminant.The impact of relativistic AGN jets on realistic galaxy cluster environments
Low-power FRI-like radio jets dominate the AGN population, yet the main mechanism of heating the intracluster medium (ICM) and its efficiency remain a matter of debate.The star formation history of Orion is structured and episodic
The propagation of star formation throughout a molecular cloud complex can tell us much about its physical drivers and the importance of environmental versus intrinsic processes.Star Formation Mitosis: The Effects of Particle Splitting on the Star Formation Outcome
Particle splitting can increase the dynamic range in Lagrangian astrophysical simulations by several orders of magnitude.The Impact of Simulation Resolution on Dwarf Galaxy Stellar Stream Populations in FIRE
Cosmological simulations allow us to study galaxy-progenitor stream populations, allowing comparisons with observations to constrain galaxy formation physics.Everything Everywhere All At Once: A Hierarchical Framework for Mapping Anisotropies in the Local Universe
We present a Bayesian hierarchical forward model for mapping the local luminosity-density field from heterogeneous redshift surveys.An Ionized Superstructure at Cosmic Dawn Revealed by a Foundation Model for Astrophysical Research
The spatial structure of cosmic reionization remains poorly constrained.A Bayesian Inference Framework for Binary Lens Events Fully Incorporating Higher-Order Effects
Higher-order effects, such as microlensing parallax and lens orbital motion, are essential for characterizing the physical properties of microlensing planetary systems including their masses and…Population search for dark matter spikes in megamaser rotation curves
A black hole growing adiabatically inside a dark matter halo is expected to develop a dense spike, with a power-law slope between 1.5 and 2.5, depending on redshift and baryonic activity.Broadband reverberation mapping of quasars at cosmic noon
Broadband reverberation mapping provides a powerful tool to investigate the structure of the accretion flow around supermassive black holes.Testing KMTNet--PRIME Optical--Near-Infrared Source-Color Constraints in KMT-2024-BLG-0211 and KMT-2024-BLG-1522
We present analyses of two 2024 microlensing events, KMT-2024-BLG-0211 and KMT-2024-BLG-1522, jointly observed by KMTNet in the optical and PRIME in the near-infrared.Dynamical friction vs. subhalo heating in Cold Dark Matter haloes
The orbital evolution of massive stellar systems embedded in dark matter haloes is governed by competing processes.Morphological Identification of Dynamical Regimes in MHD Turbulence with ScaleAware-JEPA
The morphology of turbulent interstellar gas reflects the coupled action of turbulence, magnetic fields, and self-gravity, but density amplitude alone does not uniquely specify dynamical state.LUMA: A CNN for Strong Gravitational Lens Searches in Astronomical Imaging
We present LUMA, a convolutional neural network (CNN) pipeline for the automated detection of strong gravitational lenses in simulated astronomical imaging.Detecting Extragalactic Exoplanets With Fast Radio Burst Nanolensing
Fast Radio Bursts (FRBs) are spatially and temporally compact sources at cosmological distances.MEGATRON: Dwarf Galaxy Quenching in the Epoch of Reionization
Low-mass galaxies during the Epoch of Reionization are expected to form stars in short bursts separated by periods of inactivity, but what regulates this cycle, and how sensitive it is to the…The Irreversible Depletion of Dark Matter Spikes by Extreme-Mass-Ratio Inspirals
Dense dark matter spikes around massive black holes (MBHs) have been widely predicted to produce gravitational-wave dephasing in extreme-mass-ratio inspirals (EMRIs) that are potentially observable…The ALPINE-CRISTAL-JWST Survey: Investigating the role of interstellar dust, gas and stars in high-z galaxies at kpc-scales
A comprehensive understanding of galaxy evolution requires a detailed analysis of gas and dust, their distribution, and evolution within galaxies.Caught in the act: diffuse stellar and Ly$α$ emission around a halo-less quasar in the assembling cluster CARLA J0800+4029 at z=2
Extended Ly$α$ emission is commonly detected around luminous quasars at $z\sim2$-3 and traces cold gas in the circumgalactic environment of the AGN.Fooled by mass? Recovering the $Γ-λ_{Edd}$ relation of quasars from their X-ray variability
We measure the relation between the X-ray photon index $Γ$ and the Eddington ratio $λ_{Edd}$ in unobscured type-1 quasars, using as parent sample the cross-match of the SDSS DR16Q catalogue with the…
