This paper introduces EllipSect, a Python-based tool that complements GALFIT 3 by generating publication-quality visualizations, exportable data, and non-parametric measurements to facilitate the quantitative assessment of galaxy surface brightness models.
This study analyzes 67 galaxies in the PHANGS-ALMA survey to reveal how cloud-scale gas properties, particularly gas surface density and virial parameter, influence molecular gas depletion times and star formation efficiency, while highlighting the sensitivity of these results to CO-to-H2 conversion factors and their potential for comparison with numerical simulations.
This paper proposes that wave-optical interference patterns in the voltage auto-correlation of Fast Radio Bursts (FRBs), caused by collective microlensing from stars in a lensing galaxy, could serve as a unique signature to identify strongly-lensed FRBs even when only a single image is detected.
This paper introduces ARCANE, a novel framework that achieves robust, early detection of interplanetary coronal mass ejections in streaming solar wind data by leveraging a ResUNet++ machine learning model, which significantly outperforms threshold-based baselines while maintaining high performance even with real-time data constraints.
This paper establishes a foundational framework for synergistically detecting ultralight axion-like dark matter by combining Pulsar Timing Arrays and Pulsar Polarization Arrays, specifically deriving three-point correlation functions and Bayesian likelihoods that account for the non-Gaussian nature of timing signals to enhance detection capabilities.
SpiralMap is a Python library that compiles nine major models of the Milky Way's spiral arms, enabling users to extract their 2D traces and visualize them in various coordinate frames and tracers.
This paper reports a new ground-based transit detection of the long-period, low-density exoplanet HIP 41378 f, which refines its orbital ephemeris and suggests that planet d, rather than planet e, may be the primary driver of the system's transit timing variations.
This paper proposes and validates through 3D magnetohydrodynamic simulations a model where two distinct AGN jet episodes launched 15 and 5 million years ago from the Galactic center generated the outer eROSITA bubbles and inner Fermi bubbles, respectively, successfully reproducing their observed multi-wavelength morphologies and physical properties.
This review synthesizes recent advancements in identifying red supergiants across the Milky Way and nearby galaxies, highlighting how improved methodologies, expanded datasets, and new discoveries regarding variability and binarity are refining our understanding of massive star evolution and the Humphreys--Davidson limit.
This paper models the spectral energy distributions of rotating Population III stars to demonstrate that they can produce strong He II 1640 emission lines without requiring extremely high stellar masses, while also assessing their modest but potentially detectable impact on the global 21-cm signal and power spectrum during cosmic dawn.
This study demonstrates that the thermal evolution and inferred radii of Neptune and sub-Neptune exoplanets are highly sensitive to thermal conductivity assumptions in non-convective, compositionally stratified layers, revealing that current theoretical uncertainties significantly exceed observational errors and necessitate improved data on material properties and primordial states.
This study employs an uncertainty-aware hybrid machine learning framework trained on Bayesian-inferred observational probability density functions to constrain fuzzy dark matter models using 21-cm neutral hydrogen fraction data, identifying a best-fit scenario with a particle mass of approximately $10^{-22}\,\mathrm{eV}$ and a fraction of 0.04 while ruling out lighter masses.
Based on archival Hubble Space Telescope observations from 2015 to 2019, this paper presents a preliminary circular orbit for Makemake's satellite with a period of approximately 18 days and an edge-on inclination that suggests the potential for mutual events between the dwarf planet and its moon.
This study introduces a novel method that applies cosmological reconstruction to the void-galaxy cross-correlation function, enabling the inclusion of small nonlinear voids and achieving a 23% improvement in constraining Alcock-Paczynski parameters compared to traditional redshift-space analyses.
This study proposes that the recently detected 220 PeV neutrino (KM3-230213A) is a cosmogenic neutrino consistent with minimal ultra-high energy cosmic ray flux models derived from Telescope Array data, while also satisfying constraints from gamma-ray observations.
This study utilizes a 3-D polyhedral shape model to comprehensively analyze the surface dynamics, gravitational potential, and orbital stability of comet 67P/Churyumov-Gerasimenko, revealing that most surface slopes are low, escape speed peaks in the Hapi region, and specific equilibrium points and periodic orbits exist despite minimal perturbations from third-body gravity and solar radiation pressure on larger particles.
This paper presents a blind analysis of seven independent mass models for the MACS J0138-2155 cluster, which uniquely strongly lenses two supernovae (Requiem and Encore), to predict future image appearances and derive a Hubble constant measurement of km s Mpc based on the time delay of SN Encore.
This paper presents a new determination of the evolving far-infrared galaxy luminosity function and dust-obscured star formation rate density out to redshift z~6 by combining ALMA follow-up data with stacked optical/near-infrared samples, revealing that the characteristic luminosity increases monotonically with redshift while dust-obscured activity contributes less than 25% to the total star formation rate density by z~6.
This paper presents a realistic forecast demonstrating that detecting the 21cm-galaxy cross-correlation and distinguishing reionisation scenarios requires wide-area, medium-to-deep slitless spectroscopic surveys that effectively sample large-scale modes, with optimal performance achieved at redshifts greater than 7.
